摘要
本文针对黄土高原及宁夏南部山区普遍存在的水土流失与生态经济严重失调问题,从生态与经济、治理与开发、近期与长远、定性与定量相结合的角度,应用系统工程方法提出了黄土丘陵区农林牧优化结构的设计原理与理论模式。该模式不仅揭示了黄土丘陵区建造优化结构的巨大生产潜力,而且从理论与实践结合的角度阐明了建造优化结构的途径与技术措施,是应用生态经济系统工程寻找黄土高原治理途径的新尝试。
Building principle and theoretic model of optimum farming, forestry and animal husbandry structure at loess hill area is put forward by the way of systematic project from both ecology and economy,harness and development, in the near and far future, and determining the nature and quantity, which is directed aginst those common problems of soil/water loss and serious ecological-economic dislocation at mountain area of southern Ningxia Hui Autonomous Region.This model successes not only on revealing the tremendous productive potentialities of optimum structure but also on expounding the way and the technique of how to establish the structure. It is a new attempt in seeking the way to harness the Loess Plateau from systematic project principle.
