It is thought that the theory of soil and water ecology clarifies the complicated problems of ecological environment. Environmental pollution can be controlled,but it is only a matter of time and cost. Soil and water ecology is the root of ecological environment problems. The clean water and green mountain are destroyed,which cannot be restored. With the theory of soil and water ecology,the idea that clean water and green mountain are golden and silver mountains is read,as well as the way of turning clean water and green mountain into golden and silver mountains and its different impacts on eco-environment. The developed and underdeveloped areas should treat the idea that clean water and green mountain are golden and silver mountains. The application of the theory of soil and water ecology in soil and water conservation broadens the space of soil and water conservation,and it is necessary to establish a national commission for the conservation of soil and water ecology. The theory of soil and water ecology is the golden key to solve the problems of contemporary ecological environment and the theoretical basis for building a beautiful and rich China.展开更多
以太行山区(华北平原水源地,分属黄河流域和海河流域)为研究对象,建立了分布式水文模型WEP-L(Water and Energy transfer Processes in Large river basins),模拟了1980-2000年间山区的水循环过程,总结了蓝水(径流性水资源)和绿水的年...以太行山区(华北平原水源地,分属黄河流域和海河流域)为研究对象,建立了分布式水文模型WEP-L(Water and Energy transfer Processes in Large river basins),模拟了1980-2000年间山区的水循环过程,总结了蓝水(径流性水资源)和绿水的年际及随高程的变化规律。在此基础上,定量区分了研究区气候波动和土地利用/覆盖变化对蓝水与绿水变化的贡献。研究结果表明:(1)太行山两侧的蓝绿水变化具有明显的差异;海河片区蓝水呈增长趋势,绿水呈下降趋势;黄河片区蓝水呈减少趋势,绿水呈增长趋势。(2)太行山区蓝水资源量变化的主导因素是气候波动。(3)土地利用/覆盖的改变是太行山区绿水变化的决定性因素。植被增多可增加绿水资源的利用,但同时将明显减少对经济社会发展非常重要的蓝水资源量。因此,山区国土资源开发与空间优化须重点考虑蓝水和绿水的合理调控。展开更多
