中文摘要	以艾比湖湿地国家级自然保护区为研究区,选用1972年、1998年、2007年和2013年9月或10月的Landsat MSS、Landsat TM和Landsat OLI遥感影像为主要数据源,采用像元二分方法,得到研究区的植被覆盖度,并将植被覆盖度分为3个等级;运用转移矩阵法,分析植被覆盖度变化情况。研究结果表明,与1972年相比,1998年植被有大幅度的改善,1998年低覆盖度(植被覆盖度≤30%)植被面积增加了708.80 km~2(占22.30%),植被类型主要为荒漠草原,高、中覆盖度植被面积分别仅增加不到3 km~2(占0.09%);与1998年相比,2007年该保护区的低覆盖度植被面积减少了943.82 km~2(占29.69%),高覆盖度植被面积减少了1.24 km~2(占0.04%),而中覆盖度植被面积增加了0.9 km~2(占0.03%);与2007年相比,2013年该保护区的低覆盖度植被面积减少了232.73 km~2(占7.32%),中覆盖度植被面积减少了0.84 km~2(占0.03%),而高覆盖度植被面积增加了1.96 km~2(占0.06%);与1972年相比,2013年该保护区的低覆盖度植被面积减少了467.75 km~2(占14.71%),高、中覆盖度植被面积都有所增加,分别增加了3.56 km~2(占0.11%)和3.01 km~2(占0.09%)。从空间变化来看,1972~2013年,艾比湖湿地国家级自然保护区植被减少了461.14 km~2,1998~2013年期间,该保护区东部植被面积大幅减少。
英文摘要	Vegetation fractional coverage is an important index to describe and evaluate the ecological system. Using Landsat MSS/TM/OLI remote sensing data in September or October 1972, 1998, 2007 and 2013, the change of vegetation coverage in Aibihu Wetland National Nature Reserve was studied in this paper. Pixel dichotomy method was used to get vegetation coverage and grades of vegetation coverage were classified; then using the transfer matrix method, and the transfer areas of 3 kinds of vegetation coverage between 4 periods were analyzed. The results showed that vegetation area had greatly increased in 1998 compared with that in 1972, the vegetation area of low coverage (vegetation coverage is less than or equal to 30%) increased by 708.80 km~2 (22.30%), the vegetation was mainly desert grassland, and the vegetation areas with high and middle coverage increased by less than 3 km~2 (0.09%). The vegetation coverage was significantly decreased in 2013 compared with that in 1998. The vegetation area with low coverage decreased by 943.82 km~2 (29.69%) in 2007, the vegetation area with high coverage was decreased by 1.24 km~2 (0.04%), and the vegetation area with middle coverage increased by 0.9 km~2 (0.03%). The vegetation area with low coverage decreased by 232.73 km~2 (7.32%) in 2013 compared with that in 2007, the vegetation with middle coverage decreased by 0.84 km~2 (0.03%), and the vegetation area with high coverage increased by 1.96 km~2 (0.06%). The vegetation area with low coverage decreased by 467.75 km~2 (14.71%) in 2013 compared with that in 1972, the vegetation areas with high and middle coverage increased by 3.56 km~2 (0.11%) and 3.01 km~2 (0.09%). The area of vegetation coverage in Aibihu Wetland National Nature Reserve decreased 461.14 km~2 in 2013 compared with that in 1972. The vegetation area in the east of the reserve decreased obviously.
