| 摘 要： | 基于归一化植被指数（NDVI）分析方法，选用1977年Landsat、1992年TM、2000年ETM^＋卫星影像，分别对石林风景区及石林县除石林风景区外的NDVI进行了计算和分析，结果认为，1977～2000年石林风景区植被覆盖度整体呈下降趋势，由1977年的62．15％下降到2000年的60．07％．对造成这一结果的原因进行了浅析．

| Abstract: | Based on the method of NDVI,the NDVI of Stone Forest and other areas of Shilin county were calculated and analyzed by choosing the data of Landsat in 1977,TM in 1992,ETM and satellite image in 2000.The results indicated that the vegetation coverage of stone forest scenic spot showed the tendency of declination,decreased from 62.17 % in 1977 to 60.07 % in 2000,the reasons for this result were analyzed as well. |
