摘要
我国绝大多数煤矿集中区生态环境脆弱,存在地表植被破坏、水土流失和土地荒漠化等现象。NDVI作为监测植被生长状态及地表覆被变化的最佳指示因子,是反映生态环境状况的重要指标。本文基于Landsat系列卫星影像,利用趋势分析和像元二分法对1995—2016年攀枝花煤矿集中区NDVI和地表覆被变化开展了研究。
Most of the coal mines in our country have fragile ecological environment,such as destruction of surface vegetation,soil erosion and land desertification. The NDVI as the best indicator of vegetation growth status and land cover changes,is an important index to reflect the status of ecological environment. Based on the Landsat series of satellite images,the trend analysis method and pixel dichotomy were used to study the NDVI and land cover changes of the Panzhihua coal mine concentration area from 1995 to 2016.
