生态环境退化对农业生产的影响--以塔里木河下游为例

由于人类近 5 0a不合理的水、土资源开发 ,造成塔里木河下游的生态环境退化日益严重。在人类发展经济而破坏生态环境的同时 ,生态环境退化又给塔里木河下游的经济发展带来了灾害性的影响 ,主要表现在 :土地沙漠化大面积发生 ;灾害频度和强度增加 ;草地退化制约了畜牧业的发展 ;水质污染影响了农业生产等。这些影响在很大程度上限制了塔里木河下游经济的发展。本文通过在塔里木河下游的调查资料 ,分析了坚持生态环境建设与经济发展相结合的重要性。同时 ,就该地区的实际情况 ,提出生态恢复和重建的建议。

The Effect of Eco-Environment Degradation on Agriculture--Taking the Lower Reaches of Tarim River as Example

Due to the irrational exploitation of soil and water resources in recent 50 years, many environment {problems have appeared in the lower reaches of Tarim River, which made the environment degradation}of this region serious. When human develop economy at the expense of the eco-environment, the ecological degradation also bring disastrous effect on the economy development in the lower reaches of Tarim River. These effects can reflect in the following several points: the desertification occurred in large scope; the disastrous extent and intensity increased; the grassland degradation restrictedthe stockbreeding development; the water pollution preventedthe agriculture development. Such problems were the important reasons which affected this regions'economy development in certain extent. According to some basic data investigated in the lower reaches of Tarim River, the importance of the relation between the eco-environment protection and the ecology development was analyzed in this article. In addition, the suggests about ecological restoration and rebuilding were also put forward according to the factual condition of this region.
