摘要

拟建的黄河大柳树水利工程对于黄河流域水土资源的有效利用和库区、灌区群众生存条件的改善具有重要的意义。但是水利工程移民引起的生态与环境问题也不容忽视。通过人 -地关系模型计算了大柳树工程移民前后对安置区产生的人口胁迫力变化

结果表明

移民使安置区土地的人口压力增加了 3.9倍。移民居住点、交通设施等的建设活动和土地开发利用也可能导致安置区的土地荒漠化

因此

必须预先采取相应的措施

缓解土地压力、防止土地荒漠化。

Abstract

The Daliushu Dam on the upstream of Yellow river will play an important role in rational utilization of water and land resources and improving the survival conditions for local people. But the environmental problems caused by the dam must be pay more attention. Using a Person Land model

the population stress of engineering immigrants on land are calculated. The results show that the population pressure on land increases by 3.9 times after the immigrants enter. The building activities of settlement and traffic facility and land exploitation and utilization may induce land desertification and hence

the area of deserted land rises. So it is necessary to take measures for reducing land pressure and preventing land desertification early.
