| 摘 要： | 针对水电梯级开发将改变水资源时空分布并引起流域植被环境的变化,以湖北省清江流域为例,采用基于归一化差异植被指数的像元分解模型和TM/ETM+遥感数据对研究区域水电梯级开发不同时期的植被环境态变化进行了定量估算.结果表明,该法有效可行,且水电梯级开发对清江流域植被境的影响较大,1987～2004年清江中下游的植被环境有较大改善. |

| Abstract: | Hydropower cascade development will change the spatial and temporal distribution of water resources,thus lead the vegetation environment to change in watershed.In this paper,the pixel decomposition model based on normalized difference vegetation index(NDVI) and TM/ETM+ imageries have been applied to quantitatively analyze the dynamic change of vegetation environment in Qingjiang River basin.The results indicate that the hydropower cascade development has a greater influence with the change of vegetation env... |
