Abstract


Wudinghe right bank of a tributary of the Yellow River, flows through the northern Loess Plateau, the largest river in Yulin City. In recent years, with the national energy base construction Yulin City, has made great economic and social development, the demand for water has increased dramatically, and in the context of global warming, is located in the arid and semi-arid regions Wuding River Basin variability of precipitation tendency of further expansion, making the already fragile ecological environment worsened, decades of struggle sand obtained results may be in vain, in reduced precipitation, vegetation was destroyed large areas of the case Maowusu The direct-drive south to the desert, no barriers can be used as a direct threat to the Guanzhong area and northern regions of ecological safety. Wuding River basin rich in mineral resources, and the development of these resources, demand for water will be enormous. Wudinghe drying up, the future national energy base construction has brought uncertainty, water has become a constraining economic development in the watershed biggest bottleneck. Wudinghe stop exploring the causes and effects and solutions for industrial and agricultural Wudinghe of drying methods and measures, is the development of the local economy and improve people's lives have to face a problem, but also the smooth construction of national energy base, the protection of national Energy security is a big key factor. In this paper, a large number of reference Wudinghe River hydrological climate change, economic trends and the ecological environment planning and other planning documents and government reports, based on a large number of domestic and foreign see the rivers on the ecological environment, economic and social impacts of development on , according to the occurrence Wudinghe situation of water resources and utilization in predicting future population and industrial and agricultural development of the region on the basis of size, to determine the extent and future water shortages in this under the influence of the degree of influence on the industry and agriculture. The main conclusions are: climate change and human factors under the double impact Wudinghe drying trend will become more severe. With the development of industry and agriculture, water crisis will deepen the degree of conditionality more obvious agricultural, ecological water demand and development of industrial and agricultural demand for water more acute contradictions and difficult balance. In response to the basin cutout impact of economic and social development, this paper attempts to improve the ecological environment of the basin, regulating spatial and temporal distribution of water resources, improve water utilization, increase publicity and awareness of water conservation measures and other aspects to slow down the drying Wudinghe frequency and its impact on the protection of the local ecological security and economic development on water resources needs to find the right balance point to promote Wudinghe River sustainable economic and social development.
