【摘要】 疏勒河流域地处极度干旱的河西走廊西部 ,是正在兴建的农业灌溉区。随着流域新一轮水土资源的大规模开发利用 ,必然引起与地表水—地下水循环转化系统密切相关的生态环境条件的恶化 ,已出现了类似石羊河、黑河流域水土资源开发利用过程出现的植被衰亡、草场退化、泉水衰减、土地盐渍化、沙漠化等生态环境问题。本文依据 2 0世纪 90年代对疏勒河流域的实地调查资料 ,在对流域生态环境特点、环境变迁历史进行分析对比的基础上 ,着重研究了生态环境与地下水的关系 ,并提出了流域地下水影响带内植被演化模式。更多还原

【Abstract】 Environment and development are focused in the world of today and water is a link to maintain the balance between economic development and ecological environment. Shulehe river basin is located in the west of arid Hexi corridor, where is being developed a new agriculture irrigation area.In pace with a large scale development of water and land by human,the ecological environment will be changed because the variation of cycle system of surface water—groundwater is related to the environmental problems, such as vegetation dying grassland degeneration, spring water decrease, salting of soil and desertization have been occured in similar areas, for example, Shiyanghe river basin and Heihe river basin. According to the invertigated data in 90’s of twenty century, the relationship between ecological environment and groundwater is studied based on the analysis about the feature of ecological environment, current situation of desertification and historical evolution of environment and the evolution pattern of vegetation affected by groundwater is proposed. The pattern and some other conclusions maybe have reference value to draw up the development of water resources and to propose the countermeasure for environmental protection in Shulehe river basin or extended to Northwest China.更多还原
