| 摘 要： | 变化分析是多时相遥感影像主要应用领域.本文利用多时相TM影像对惠水典型喀斯特地区地表植被的变化进行了研究分析.结果证明:①用不同时相的NDVI影像进行彩色合成可以直观地反映地表植被的变化;②利用不同时相NDVI影像进行NDVI值分级可以定量地反映区域表植被的变化情况;③可以从一个侧面反映喀斯特地区环境质量的变异.

| Abstract: | Land cover change detection is an important application field of remote sensing data. in this paper, multi-temporal landsat TM image is used to study and analyze the surface vegetation change of typical Karst area in Huishui. Results of its application in vegetation change detection of Huishui show positive aspects of this method: Color composition of multitemporal landsat NDVI image gives and obvious view of vegetation change; NDVI value graded to different multi-temporal landsat NDVI image can reflect this area's vegetation quantitatively and direct changing situation.And it can reflect the environment quantity changing of Kast area in a new aspect. |

| Keywords: | surface vegetation change detection NDVI value Karst |
