| 摘 要： | 通过Quick Bird、ZY-3商业卫星影像遥感解译提取台雄水库周围区域2008年、2018年共2期的土地利用数据,基于叠图法、景观指数法分析了水库建设前后土地利用空间分布格局、变化特征等。主要结论如下:台雄水库采取了有效的植被恢复措施,工程建设对自然植被尤其是森林植被的影响有限,工程建设和运行基本未改变生态系统总体异质性,对区域生态体系的阻抗稳定性影响不大。

| Abstract: | Through quick bird and ZY-3 commercial satellite image remote sensing interpretation,the land use data of two phases in 2008 and 2018 in the area around Taixiong reservoir are extracted,and the spatial distribution pattern and change characteristics of land use before and after the construction of the reservoir are analyzed based on the overlay method and landscape index method.The main conclusions are as follows: Taixiong reservoir has taken effective vegetation restoration measures,the impact of engineering construction on natural vegetation,especially on forest vegetation is limited,the engineering construction and operation have basically not changed the overall heterogeneity of the ecosystem,and have little impact on the impedance stability of the regional ecosystem. |
