Water environmental degradation is a major issue in the Heihe River Basin belonging to the inland river basin of temperate arid zone in northwestern China. Mankind's activities, such as dense population and heavy dependence on irrigated agriculture, place immense pressure on available and limited water resources during the last century, especially the recent five decades. An investigation on the water environmental degradation in the Heihe River Basin and analysis of its causation were conducted. The results indicated that water environmental changes in the whole basin were tremendous mostly in the middle reaches, which reflected in surface water runoff change, decline of groundwater table and degeneration of surface water and groundwater quality. Some new forms of management based on traditional and scientific knowledge must be introduced to solve problems of water environmental degradation in the Heihe River Basin.
水环境退化是中国西北温带干旱区内陆河流域黑河流域的一个主要问题。在上个世纪，尤其是最近五十年，人类活动，如人口密集和对灌溉农业的严重依赖，给有限的可用水资源带来了巨大压力。对黑河流域的水环境退化进行了调查并分析了其成因。结果表明，整个流域的水环境变化巨大，主要集中在中游，表现为地表水径流变化、地下水位下降以及地表水和地下水水质恶化。必须引入一些基于传统和科学知识的新型管理方式，以解决黑河流域的水环境退化问题。
