摘要 为了研究麻阳河保护区植被覆盖度变化情况,采用2004、2007、2010年多源遥感影像的NDVI数据,运用arcgis软件计算出保护区植被覆盖度,分析麻阳河保护区植被覆盖度变化情况。结果显示,2004~2010年保护区植被覆盖变化总趋势是低、中低植被覆盖度往中、中高植被覆盖度转化,占保护区总面积的69.04%。受到保护区下游彭水电站施工影响,只有9.17%的中高植被覆盖度转化为中低植被覆盖度。保护区森林、灌丛植被覆盖面积大,植被覆盖度趋于正向转换,呈良性恢复趋势。 In order to study the vegetation coverage change of Mayang River protected section, using the multi-source remote sensing image' s NDVI data of 2004,2007,2010. Using ArcGIS to calculate vegetation coverage changes of the protected section to analysis the changes of Mayang River protected section' s vegetation coverage changes. The results show that, during the six years since 2004 to 2010, the trend of the protected section' s vegetation coverage changes is the low, middle-and-low level trans- form to the middle, high-and-middle level which accounts 69.04% of the entire protected section area. Affected by the construction of Pengshui hydropower station, only 9.17% of the middle-and-high vegetation coverage transform to the middle-and-low level. The area of forest and shrub vegetation is large in the protected section, vegetation coverage tends to be positive reversal and recovery well.
