在Spot Vegetation NDVI时序数据的基础上,结合土地利用数据,对鄂西南地区近13年来植被覆盖状况的时空变化过程进行系统分析,并对其变化原因进行了探讨。结果表明,鄂西南地区主要土地利用类型为林地,绝大多数地区植被覆盖度均在75%以上,植被覆盖状况和生态环境整体优良;2001-2009年鄂西南地区植被覆盖状况保持稳定,并从2010年后开始呈现明显好转的态势,植被覆盖度好转地区的面积大于变差地区的面积,表明该区域自实施一系列林业生态工程以来生态环境得到了保护和逐步恢复。气温和降水量对鄂西南地区植被覆盖状况变化的影响不明显;2001年以来林业生态工程的实施是引起鄂西南地区自然植被覆盖状况逐...

With the support of land use data and long time series data of spot vegetation NDVI,the spatial-temporal variations of the vegetation coverage from 2001 to 2013 were systematically analyzed, and the main causes in the southwest of Hubei province in the recent years were explored. The results showed that the main land use type was woodland and the vegetation coverage degree in most parts of the region was more than 75%. The vegetation cover condition remained stable in2001 to 2009 and got better after 2010, and the areas that vegetation coverage degree increased was larger than that of decrease...
