Abstract:

本文以2007、2009和2012年的5月和9月共6个时期的遥感影像,基于栅格数据和综合评价模型,对若尔盖县的生态环境质量状况进行了评价。首先,从影响生态环境质量的因子出发,选取归一化植被指数(NDVI)、地表温度、坡度、坡向、土地利用、湿度指数6项生态因子作为评价指标;然后,利用主成分分析法确定各评价指标的权重,根据综合指数评价模型计算出研究区的生态环境质量指数,同时,依据计算结果的大小把研究区的生态环境质量划分为优、良、中、差4个等级;最后,对若尔盖县的生态环境状况的空间分布规律进行分析。结果表明,2007-2012年若尔盖县生态环境质量良好,不同时相的生态环境综合指数的均值均在60左右,同时该区域的生态环境质量有变好的趋势;不同季节的评价结果稍有差异,但是同一季节不同年的变化趋势是一致的;不同等级的区域相间分布,较差区域主要集中在植被覆盖较差的区域,西北部居多,中部零星分布。
