| 摘 要： | 基于归一化植被指数(NDVI)分析方法,利用黄山风景名胜区新云谷索道建设前(2004年)后(2008年)的2个时相的遥感数据对索道建设区进行植被覆盖动态变化分析。结果表明:新云谷索道建设后周边的植被覆盖和生长情况明显优于建设前,森林生态系统正向演替没有因为工程建设而受到限制,工程建设导致的人工干扰没有使植被遭受明显破坏,研究区植被生态系统的结构与功能没有因索道建设而受到影响。以遥感技术(Remote sensing,RS)为手段的风景区植被指数分析方法在生态环境研究中具有广阔的应用前景。

| Abstract: | Based on Normalized Difference Vegetation Index （NDVI） method,it analyzed the dynamic changes of vegetation cover before（2004） and after（2008） the construction of New Cloud Valley cableway by the remote sensiong data.The results showed that：the surrounding vegetation cover and the growth condition after the construction of New Cloud Valley cableway was superior to that before the construction,the positive succession of forest ecosystems was not limited,vegetation were not suffered obviously from artificial intederence,vegetation ecosystem structure and function were not affected.So,remote sensing technology （RS） as a method of scenic vegetation index anaysis has broad application prospects in the study of ecological environment. |
