麻阳河黑叶猴自然保护区生境对彭水水库蓄水响应的遥感监测分析

为揭示贵州麻阳河黑叶猴自然保护区生态环境对彭水水库建设的蓄水响应关系，为该保护区原始生态环境和黑叶猴生境的科学评价与保护，植被覆盖的恢复提供参考依据和基础数据，本文对彭水水电站建设前、中、后保护区生态环境变化进行动态监测，保护区对彭水水电站建设蓄水的响应进行分析。结果表明：彭水电站建设后在自然保护区范围内淹没面积仅有4.8 hm2，只占整个自然保护区面积的0.1%，主要影响区域在洪渡河流域的淹没区，水位上涨导致土地利用、水土流失有部分变化。说明水库蓄水对整个自然保护区生态环境的完整性影响较小。

Remote Sensing Monitoring and Analysis of Responses of Ma Yang Francois Nature Reserve to Impoundment of Pengshui Reservoir

The ecological environmental changes of Francois langur natural reserve was monitored during Pengshui Reservoir construction and influence of reservoir fil-ing on the habitat of the natural reserve was analyzed to provide the scientific basis and basic data for scientific evaluation and protection of original ecological environ-ment of the natural reserve and Francois langur’s habitat, and vegetation recover. The results showed that 4.8 hm2 of the nature reserve was submerged after reser-voir fil ing, which occupied for 0.1% of total area of the natural reserve only. The main influence area was in the submerged area of Hongdu River basin. The water level rise resulted in partial changes in land utilization and soil erosion, which indi-cates that reservoir fil ing has insignificant effect on ecological environment of the whole natural reserve.
