构建黄土高原地区水土资源可持续开发与利用三结构模式——以陇东(平凉)黄土高原地区为例

Building Three-structural Model for Sustainable Development and Utilization of Soil and Water Resources in Loess Plateau Region——A Case Based on Pingliang Region of Eastern Gansu in the Loess Plateau

传统方式的土地利用结构及结构模式,容易误导人们理解为农业土地利用结构。重新构建的水土资源可持续开发与利用结构模式,遵循水土资源利用总体经济效果最大原则,把生态环境利用、经济与社会利用严格加以区分,并建立起可持续开发与利用的协调机制,使三者形成一个比较稳定的结构模式。通过协调和规范生态环境、经济与社会对水土资源利用的结构比例,实现人与自然和谐共存与发展。

For a long time, traditional utilization structure of land and its model are easy to make people misunderstand the structure of agricultural land. According to the principle that the economic effect must be maximized in utilization of soil and water resources, the structural model for developing and using soil and water resources sustainable was set up again, which not only strictly distinguished the biological use from economic and social use, but also established the mechanism for coordinating, so that a more stable structural model was formed. Nature and human being can develop in harmony together by coordinating structural proportion of biology, economy and society. 
