黄土高原生态环境建设关键性问题的研讨

Discussion on Key Problem of Eco-environment Construction on Loess Plateau

该文以学习贯彻中央领导“治理水土流失，建设生态农业”的批示为基础，研讨有关的科学技术问题。以生态环境演变为主导，论证了自然侵蚀和人为加速侵蚀的发生发展过程及其调控的基本原理。以生态环境建设系统工程为目标，研讨了治理水土流失、侵蚀环境调控、农田建设、水利建设及防止新的人为加速侵蚀等，提出了应强化研究的关键性和基本规律性的科学技术问题。

According to the center leader's instruction of 'soil erosion control and ecological agricultural construction”,this paper discuss some related scientific and technical problems.Considering the evolution of ecological environment,it proves that the genetic and developmental processes of natural and human's accelerated erosion and the basic principle of their control must be thoroughly understood.To the goal of system engineering construction of eco-environment,it discuss the related and coordinated problems of soil erosion control,erosion environment regulation,silt decreasing in the Yellow River and ecological agricultuated construction.Considering the important measures of eco-environment construction including the integral planing making ,vegetation reconstruction,farmland construction,water resource construction and prevention of new human's accelerated erosion et,it points out that some researches on the scientific and technical key problem of the basic principle should be strengthened.
