摘要
以SPOT 6卫星影像为数据源,以安徽省灵璧县渔沟地区为研究区,利用植被指数模型和像元二分法计算渔沟地区的植被覆盖度,按照等差级数将研究区植被覆盖度密度分割为无植被覆盖区(0-0.2)、较低植被覆盖区(0.2-0.4)、中植被覆盖区(0.4-0.6)、较高植被覆盖区(0.6-0.8)和高植被覆盖区(0.8-1)5个等级,并统计不同植被覆盖区的植被面积。研究成果对磬云山灵璧石国家地质公园的生态环境建设和保护起到一定促进作用。
Using Yugou district of Lingbi county in Anhui province as the study area,and the SPOT-6's image as the data source,the fractional vegetation coverage was extracted by the NDVI and pixel dichotomy models.According to the arithmetic progression,the study area was divided into no vegetation coverage zone,low vegetation coverage zone,vegetation coverage zone,high vegetation coverage zone and extremely high vegetation coverage zone,and counted the areas of different vegetation coverage aones.Research results will play a certain role on the ecological environment construction and protection of Qingyunshan National Geological Park.
