疏勒河流域中游生态环境变化及成因分析

近三十年来,疏勒河流域中游地区生态环境不断恶化,主要表现为绿色生产严重退化,湿地面积缩小,盐碱地,沙地迅速增加。通过不同时段的遥感解译,分析了不同生态景观的定量变化及成因。恶劣的地理环境加上人类活动对水资源利用量的不断增加是造成该区生态环境日趋恶化的主要因素。保护地下水平衡和合理用水结构,实行水资源优化管理,提高水的利用率是社会经济,环境可持续发展的有力保证。

Study on the eco-environment change of the middle reaches of Shule river

The eco environment of the middle reaches of Shule River has been continuously deteriorating for almost three decades.The main results are degeneration of the vegetation,reducing of the swamp area and the increasing of the area of salting soil and sands.The quantity change and the cause of formation were analyzed by the interpretation of the remote sensing of different periods.The study indicates that the abominable geographical environment and the continuous increasing need of the water resources are the main reasons of the deterioration of the eco environment in this region.To manage the water resources scientifically and to increase the using effciency of the water are the guarantees of the sustainable development of the social economy and environment.
