沙漠化土地整治中几个问题的探讨

Discussion on Several Problems Concerning Desertified Land Rehabilitation

本文通过对土地沙漠化整治中几个问题的论述和分析,提出在沙漠化整治中首先应处理好开发与保护、整治与生产,以及生态效益与经济效益的关系;其次应处理好封沙育林育草与解决农村能源(燃料)的关系,要考虑沙区人民的切身利益,启发群众治沙的自觉性;再次,我国沙漠化与发展之比为1:8,说明沙漠化整治的速度相当缓慢。因此,依靠旱生植物治沙已不能满足沙漠化整治的需要。要缩小沙漠化整治与发展的比例,应尽可能采用“以水治沙”(水路)和“植物治沙”(旱路)相结合的治沙之路,才能加快我国沙漠化土地的整治。

In this paper the authors discussed several problems concerning desertified land rehabilitation. For this purpose, we must correctly handle the relations, such as land development and its protection, rehabilitation and production as well as ecological benefit and economic benefit. In addition,we should resolve fuel supply and the problem of closing off sandy land for vegetation growth. According to investigation data the rehabilitation of desertified land in our country is rather slow, the ratio beteen rehabilitation are and expanding area is roughly at 1 : 8. In order to speed up the rehabilitation of desertified land the biological control measures have to be combined with irrigation.
