摘要: 通过对河西地区疏勒河下游的生态环境的恶化,终端湖泊的后退,湿地萎缩,生物多样性减少,土壤盐渍化及土地沙漠化扩展的主要原因的调查分析研究,提出了生态环境保护的关键问题,并对最低水资源需求量及未来水资源保证状况进行了预测。研究结果表明,为保护和维系现存林地、草地、湿地、湖泊等生态环境不继续恶化,约需水2.92亿m3,其中安西1.5217亿m3,敦煌1.4306亿m3。但昌马水库只能提供2.4058亿m3的生态用水,还缺0.52亿m3,需通过流域实施农业节水和全面建立节水型社会解决。

关键词: 生态保护, 水资源量, 湿地

Abstract: The study area is located in the lower reaches region of the Sulehe River, Hexi Corridor of Gansu province. The paper investigated into its main causes of ecological deterioration, terminal lake retreating, wet land shrinking, bio-diversity reducing, soil salinization and land desertification developing; then has proposed the key problem of ecological environment protection, has also predicted the water resources need and the available quantity in future. For details, the water need for preventing the ecosystems of existing forest land, grass land, wet land and lake, etc. from continuously degrading is 2.92×108 m3, among which Anxi County accounts for 1.5217×108 m3, Dunhuang County for 1.4306×108 m3. Whereas, the available ecological water quantity from the Changma reservoir is only 2.4058×108 m3, so the water deficit is still 0.52×108 m3. For compensating the shortage it needs the carrying out of water-saving agriculture and even the establishment of water-saving society in the whole water basin.

Key words: ecological protection, water resources quantity, wet land
