摘要:

由于黑河下游来水量的减少,黑河下游绿洲面积急剧退化。为了改善黑河下游的生态环境问题,遏制绿洲进一步退化的趋势,国务院批复于2000年开始对黑河下游进行调水,通过9年调水,黑河下游水资源时空分布发生了很大变化。为了客观评价黑河下游植被对调水的响应,本文通过实地调查、遥感等手段,分析了黑河下游1995-2004年地下水埋深、典型植被、景观类型及东居延海在调水以来的变化情况。研究结果表明:黑河下游生态环境对调水响应明显,下游生态环境向良好的方向转变。

Abstract:

Due to water reduction, the area of oasis degraded rapidly, and many eco-environmental problems have emerged in the lower Heihe River. For the sake of improving the eco-environment, and deterring the trend of further degradation of the oasis, the water transport project in the lower reaches of the Heihe River was carried out in 2000. According to the water line, there are great changes of temporal and spatial distribution of water resources in the lower Heihe River in the past nine years. As a result, the vegetation in the lower Heihe River also changed. In order to objectively evaluate the influence of water regulation on vegetation in this region, in this paper, by means of field surveys and remote sensing, the response range and extent of the groundwater were described, and the variation of natural vegetation in the lower reaches as a result of change of the groundwater level were also described in about five years, and the rules of groundwater response to the ecological water transport were analyzed preliminarily. These results show that there are obvious effects of water regulation on the vegetation, and that the eco-environment is experiencing a good change in the lower Heihe River.
