Importance evaluation and regionalization of soil and water conservation function in Loess Plateau
摘要
Abstract
According to the characteristics of ecological environment and soil and water loss situation in Loess Plateau, the importance of soil and water conservation function was comprehensively evaluated, based on the evaluation of water conservation, soil conservation, water storage, sand-fixing, disaster prevention and mitigation, farmland protection and other service function. The results show that soil and water conservation function in Loess Plateau was of importance. 80. 03% and 19. 97% of the total area had the service function with high and medium importance, respectively. According to the evaluation results of importance of six single factor function, using overlay function of spatial analysis in ArcCIS, the basic line of division of soil and water conservation function in Loess Plateau was determined. The Loess Plateau was divided into nine division based on soil and water conservation function, and the direction of ecological protection was put forward for each division, so as to promote the the economic and social development with more effective support of natural ecological system, and lay the foundation for the improvement of the eco-environmental quality of Loess Plateau.关键词
