| 摘 要： | 分析了黑河流域生态环境恶化的现状和主要特征，主要表现为沙化加剧，绿洲萎缩；河水断流，湖泊干涸；地下水位下降，水质恶化等。在此基础上分析认为；水分条件是导致生态系统状态变化的主要驱动力，但气候变化在一定程度上加剧了生态环境恶化的进程和严重程度。因此，保护黑河流域本已非常脆弱的生态环境主要从研究水问题入手。除了调整种植业结构，大力发展节水农业；加强水资源管理以及普及节水意识等方面外，更重要的是要创新水问题研究思路，实行虚拟水战略。

| Abstract: | The ecological environment is deteriorating in the arid areas of northwest China. However, the speed and degree of ecological environment deterioration in Heihe River Basin are particularly obvious. The paper analyzes the present status and main characteristics of ecological environment deterioration in Heihe River Basin, that is, the desertification of land is aggravating, the oasis is shrinking, the rivers and lakes are drying up;the underground water table becomes lowered, the water quality becomes worsened, etc. It is suggested that water condition is the major driving factor of causing ecosystem change in Heihe River Basin, and simultaneously, the climate changes aggravate the process and severity of ecological environment deterioration to some extent. Therefore, in order to protect the fragile eco-environment in Heihe River Basin, more attentions should be paid to the research of water problems. The most important aspect is to bring forth new ideas of solving water problems and implement virtual water strategy besides adjusting the planting structure, vigorously developing water saving agriculture, enhancing the management of water resources, popularizing water-saving awareness and so on. |
