摘要 通过对石期河流域19912、002年两期遥感数据进行一系列标准化处理,运用混合像元模型反演出植被覆盖度,求解出石期河流域1991~2002年的植被覆盖变化情况。结果表明,整个石期河流域植被覆盖水平呈逐步退化的趋势。1991~2002年,石期河流域植被覆盖总面积由909.259 km2减少到882.611 km2,减少了19.993 km2,占到整个流域面积的2.19%。植被覆盖地区的覆盖度水平也有明显的变动,主要体现在中等植被覆盖度(50%~80%)面积的不断缩小,低植被覆盖度(〈30%)面积的扩大。 Through standardized processing of 2 series of remote sensing data of Shiqihe river basin in 1991 and 2002,the mixed-pixel model was used to perform the vegetation coverage degree and solve the vegetation coverage change situation in Shiqihe River Basin between 1991 and 2002.The result showed that the total vegetation coverage level of Shiqihe River Basin had a trend of gradually degradation.From 1991 to 2002,total vegetation covering area was reduced from 909.259 to 882.611 km2 in Shiqihe River Basin,decreasing by 19.993 km2 and accounting for 2.19% of the total drainage area.The vegetation coverage level in vegetation covering area also had markedly change,mainly manifesting that in the area of middle vegetation coverage(50%-80%) continue to be decreased and that of low vegetation coverage(〈30%) continue to be expanded.
