Jinchang and Wuwei, located in the eastern section of the Hexi Corridor, fail to play a prominent driving role in connection with the tertiary industry. ; visualization, X.X. Dai, J.-C.; Xie, F.; Na, K.-P. Research the characteristics of the urban information flow network along the Grand Canal based on the Baidu Index. Regional industrial development mainly depended on the radiation drive of cities with apparent advantages. Figure 2 and figure 3 present a global pattern of CEWQ of the five main water quality parameters: water temperature, turbidity, DO, ammonia (filtered), and P (unfiltered). eNotes.com will help you with any book or any question. Jinchang has a weak foundation for the development of the tertiary industry. Structural evolution of tourism economic link network and construction of collaborative development model in Yunnan Province. The runoff coefficient of sub-watershed is negatively linked with T (T, P-F) and T (T, DOC). Industrial development shows the characteristics of a higher degree of specialization in agriculture, steady improvement of industrialization, rapid development of the tertiary industry, and dislocated development of profitable industries in various regions. Betweenness centrality (BC) measures the medium function of node connections. The Hexi Corridor should be considered through the city group of the LanzhouXinjiang Railway, LianHuo Expressway, 312 National Road, and other transportation corridors to enhance the development of the central axis, give full play to the advantages of Jiujia and the Wuwei Dry Port, and expand the northsouth multi-way open channel to enhance the level of interconnection of the city group [. The Greeks were forced to adapt these characteristics in specific ways. These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds. Yang, L.-J. The many mountain ranges made it easy for each city to develop into what are called city-states (Greek: polis, plural poleis) because cities could not easily join together in larger political units. Griffith, D.A. The factors are: 1. Topography (the arrangement of natural and human-made physical features of an area) is one feature which affects human population growth. The Topography of an area can greatly influence our climate. There is a positive correlation between relief degree and elevation, and a much stronger correlation between relief degree and slope. We are also grateful to the anonymous reviewers for their generous feedback that improved the quality of this paper. Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth's tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water. Yang, L.-J. The topography of an area also helps determine the climate. The mountains also worked as barriers to separate different areas. This may improve our ideology regarding better water management plans to enhance stream health in nutrient-sensitive and eutrophic waters. Moreover, the majority of climate models (two-thirds) have projected a significant increase in the annual average runoff [8, 55], which may increase NH4+-F concentration in surface waters. several techniques or approaches, or a comprehensive review paper with concise and precise updates on the latest [ 16] found that chemical oxygen demand in water of Lake Kasumigaura, the second largest lake in Japan, increased with rising air temperature. We discuss the socio-economic and topographic factors that cause instability of CEWQ parameters and conclude with some suggestions for watershed managers to bring sustainability in freshwater bodies. Ma, D.; Zhang, C.; Hui, Y.; Xu, B. Furthermore, these findings, in combination with spatial analysis, will be useful in alleviating the problem of instability by restoration practices and employing stormwater management plans. Mountain ranges are natural barriers to air movement. P-F and DOC are abundant in tropical (A), arid (B) and temperate (C) climate waterbodies. Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth's surface. Nowadays, GIS-aided statistical analysis provides new tools to explore these relationships. GDP data was obtained from the World Bank (http://data.worldbank.org/indicator/NY.GDP.MKTP.KD.ZG). These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). The concentration of DOC is higher in the above-stated climatic types, which may be due to higher anthropogenic activity and a high rate of decomposition due to elevated temperature [45]. In 1933, it recorded its lowest temperature of -67.7C. methods, instructions or products referred to in the content. How does topography affect population? Fan, J.; Li, Y.; Zhang, Y.; Luo, X.; Ma, C. Connectivity and Accessibility of the Railway Network in China: Guidance for Spatial Balanced Development. Factor # 1. Ye et al (2009) found that topographic characteristics in the Xiangxi River in the Three Gorges Reservoir Region explained 26% variations in water quality [18].

Africa has eight major physical regions: the Sahara, the Sahel, the Ethiopian https://doi.org/10.3390/land12020274, Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. interesting to readers, or important in the respective research area. Zhong, Z.-H.; Qin, C.-L.; Ye, X.-Y. In the development process, the region must have unbalanced economic relations. This would explain the marked contrast between the city-states of Sparta and Athens. Agriculture, forestry, animal husbandry, and fishery, 2. Heated ground causes air to rise which results in lower air pressure. Rising air temperature accompanied by rainfall intensity can affect the mobilization of DOC [67]. What role did mountains play in the development of Ancient Greek culture? The response of DOC is site specific and complex to climatic drivers [67]. The delineated sub-watersheds were used for data extraction, which will be used as explanatory variables in regression models. For more information, please refer to "How did geography and topography affect Greek economic, political and social development? Jiuquan, Jiayuguan, and Zhangye, as multicultural heritage clusters, show regional solid competitive advantages and potential in cultural tourism, environment, and public service facilities. Development dynamics emerging country example (case study) Connectivity Improved Humans and wild animals face new challenges for survival because of climate change. Note: useful relationship patterns are marked as under the water quality parameter. This work was supported by National Natural Science Foundation of China (Grant No. Location and climate have large effects on income levels and income growth through their effects on transport costs, disease ; writingreview and editing, P.S. The literature illustrates that temperature has an exponential effect on sediment load (soil erosion) [72, 73]. ; formal analysis, X.X. Lett. This paper analyzes the industrial functional connection of the Hexi Corridor urban agglomeration through the urban flow intensity and industrial functional complementarity index, calculates the economic connection intensity based on the revised gravity model, and uses social network analysis to explore the evolution of the economic network structure, drawing the following conclusions. The mean elevation of sub-watershed follows the literature while the mean slope gives opposite results. Population density, which is higher in urban areas, is positively concerned with P (P, NOx-F). from Rutgers University-New Brunswick/Piscataway. Topography (the arrangement of natural and human-made physical features of an area) is one feature which affects human population growth. Dynamic Evolution of Trans-regional urban agglomeration Economic network: Based on analysis of urban agglomeration in Haixi, Yangtze River Delta and Pearl River Delta. The concept of bivariate elasticity was introduced by Jiang et al (2014) in order to measure the response of water quality parameters to precipitation and temperature [28]. and X.X. Liu, W.; Cao, Y.; Wu, W.; Guo, J. Spatial impact analysis of trans-Yangtze highway fixed links: A case study of the Yangtze River Delta, China. The above-mentioned data sets are publicly available and are at 0.50.5 latitude/longitude grid resolution. Previous studies, which used statistical approaches or process-based approaches, have discussed the river water quality relationship with, or response to, air temperature and precipitations. Economic uncertainty spillover and social networks. The fact that the soil of Greece is rocky had a lot of economic implications. The monthly air temperature (T, C) and precipitation (P, mm) data were extracted from the Global Historical Climatology Network (GHCN) [30, 31]. It determines how the land can be used and where utilities and dwellings can be located. Other city-states that were not on the Temperature usually decreases by 1C for every 100 metres in altitude. The Hexi Corridor is connected with Qinghai in the south by the Qilian Mountains and Inner Mongolia in the north by the Beishan Mountain system. It can also be considered a subfield or method in economics. Firstly, we introduce an elasticity approach (climate elasticity of water quality (CEWQ)) to characterize the response of typical water quality parameters to air temperature and precipitations (or their relationships). Nie, X.-Y. permission is required to reuse all or part of the article published by MDPI, including figures and tables. For The results are as follows. 41771130. (1) The overall function of the urban agglomeration is weak, the outward function of manufacturing is outstanding, the complementary network is highly complicated and evolving, and the environment and public service and tourism industry have apparent advantages. The climate of any particular place is influenced by a host of interacting factors. [. The water quality data were collected by the local authorities of their corresponding countries. HDI is calculated by the United Nations. Runoff coefficients for different Koppen climatic conditions were obtained from Chiew et als studies [27]. A general rule of thumb in understanding weather is warm air rises and cold air sinks. No special We will accelerate the development of Dunhuang as a famous international cultural and tourism city, support the transformation and development of Yumen as a resource-exhausted city, expand Wuwei Qingyuan Wine Town and Zhangye Nijiaying Seven-Color Danxia Town, build the Guazhou agglomeration center, highlight county characteristics, and promote the integrated development of the urban and rural economies. Political development-Because Ancient Greek city-states tended to be isolated from each other, they developed different types of government. The urban flow intensity model was used to analyze the outward function of industrial sectors in the urban agglomeration in 2020 (, According to the structural decomposition of the urban flow intensity of specific cities (, The dominant flow method is used to analyze the intensity of the urban flow of the three industries in each city, identify the industrial core backbone connection axis, and obtain the three industries first, second, third, and fourth most dominant flow directions (. Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. In order to be human-readable, please install an RSS reader. Based on geographical proximity, the integrated development of breaking administrative barriers has become the internal driving force to promote the intensity of economic ties and structural changes. The topography of an area can influence the weather and climate. He, C.-F.; Yu, C.-D. Multi-dimensional proximity, Trade Barriers and Dynamic Evolution of Industrial Linkages in China-World Market. Figure 2. How did the Greeks contribute to democracy? Some studies have reported that the mean slope and elevation are associated with enhanced erosion rates, which subsequently speed up particulate material entry into surface waters [18, 21]. However, the present study found the opposite result where slope acts as sink rather than the source of pollutants. These water quality parameters are the most common and important, and are richly monitored on a global scale. Yu, J.-K.; Ma, J.-Q. The impacts of natural environment on water quality, e.g., climate and topography, have been less studied in comparison with land use and socio-economic factors. A region's weather patterns, usually tracked for at least 30 years, are considered its climate. Watersheds were selected based on long-term water quality records. Liu, S.; Wang, Y.; Yang, P.; Chevallier, J.; Xiao, Q. Spatial correlation effects of the economic value of green infrastructure (EVGI) on social network: Evidence from China. Any further distribution of this work must maintain attribution to the author(s) and the title of the work, journal citation and DOI. Huang, X.; Huang, X.-J. The results showed that socio-economic and topographic factors threaten the stability of CEWQ parameters and we should focus on alleviating the problem of instability by Topographical features like mountains affect the weather mostly in the way that they direct air currents. Climatic factors such as light, water, and rainfall, temperature, air, relative humidity and wind also affect farming in various ways. As air cools, this water vapor is forced to condense, depositing rain or snow on windward slopes. Klages-Mundt, A.; Minca, A. Optimal intervention in economic networks using influence maximization methods. The results implied that watersheds with lower runoff coefficient, thick population density, over fertilization and manure application face a higher risk of instability. It is of great significance to strengthen the urban connection in the Hexi Corridor and give full play to the overall competitive advantage. Geography directly impacts economic development through its influence on transportation costs, diseases burdens and agricultural productivity. Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Wang, H.-H.; Zhai, L.-J. Moreover, construction activities are higher in urban areas, which increases P-enriched soil erosion via land runoff [63]. When topography comes into play, weather scenarios deviate from that rule. By which act dyarchy was introduced in india? Closeness centrality (CC) measures the proximity of a citys contact distance. Country level GDP data were assigned to their corresponding watershed. progress in the field that systematically reviews the most exciting advances in scientific literature.
