【 摘 要 】

Understanding past and current relationship between water-soil resources utilization and eco-environment is essential for predicting how these relationships may be affected by future human activities change. Combined with GIS technology and statistical analysis, based on the actual situation of water shortage, limited land resources and the prominent contradiction between the supply and demand of water-soil resources in the karst mountain area of southeast Yunnan province. This paper studies the coupling coordination relationship between the water-soil resources utilization and eco-environment in karst rocky region and evaluated the coupling coordination degree between the utilization of water-soil resources and the eco-environment by using the entropy weighting method and the system coupling theory. Results show that the model estimated the spatial and temporal variation between water-soil resources utilization and eco-environment parameters precisely. On this basis, the stress response mechanism of social and economic development and water-soil resources under the constraint of water-soil resources is further discussed by using impulse response function simulation, so as to provide theoretical and technical support for the sustainable development of regional water-soil resources.
