| 摘 要： | 格尔木河流域是柴达木盆地工农业较发达地区之一。近年来,随着流域水资源开发利用程度不断加大,用水结构欠合理,生态环境趋于恶化。本文从流域主要植物生长状态分析了地下水位埋深对植物生长的影响,确定了不同植物对地下水位埋深、地层岩性和不同盖度下的植物蒸发蒸腾强度。从研究流域生态需水量出发,分别对河道内、河道外天然植被和东达布逊湖生态需水量进行了初步估算,分析了水资源开发利用对生态环境的影响,从而为今后研究流域水资源开发利用和生态环境保护提供理论参考。

| Abstract: | Gelmud River Basin is one of the most developed industrial and agriculture areas in Chaidamu basin. In recent years, ecologic environment has deteriorated gradually with the development of basin water resource and unreasonable water use structure. This thesis analyzed the influence of groundwater depth to plant growth from the grow situation of main plants in the basin, and confirmed different groundwater depths, lithology character and plant evaporate strength under different coverage degrees. From the research on basin ecologic water demand, the paper preliminarily estimated on the natural vegetation of inner river and outer river and ecological water demand of east Dabuxun lake, analyzed the influence of water resource development to ecological environment, and provided the theoretical basis for the research on basin water resource development and ecological environmental protection. |
