利用1 km空间分辨率的MODIS数据,对2007年～2016年的归一化植被指数(NDVI)时间序列数据以及NDVI与气象因子、土地利用类型、海拔高度的相关关系进行分析,研究近10a湖北省植被覆盖度在时间和空间上的变化特征.结果表明:全省年平均NDVI波动上升,从各季节变化线性拟合结果来看,冬季上升程度最大;NDVI月变化呈单峰型,最高值出现在7月份,为0.758,最低值出现在1月份,为0.383;在空间分布上,湖北省西部地区NDVI较大于东部地区,十堰、恩施和神农架林区植被覆盖度高,武汉和鄂州植被覆盖度低;降水量、海拔高度和土地利用类型与NDVI均有较显著的相关性,植被生长对降水的响应具有滞后性;高海拔山地地形区林地...

Based on MODIS data with 1 km spatial resolution, the NDVI time series and correlation between NDVI and meteorological factors, land use types and altitude, respectively, were analyzed to study characteristics of vegetation coverage in time and space of Hubei Province from 2007 to 2016. The results show that the annual NDVI increased slowly with fluctuation, and the seasonal NDVI increased most in winter. The monthly variation of NDVI was the single peak type. The highest value appeared in july as 0. 758. The lowest value appeared in January as 0. 383. In the spatial distribution, NDVI in the ...
