摘　　要： 以马来西亚雪兰俄州为例,利用逐次投影寻踪模型进行了生态环境脆弱度评价。在评价过程中,评价指标中加入了基于遥感的表征指标,并且通过逐次投影寻踪模型确定指标权重。结果表明,该地区的生态环境脆弱度不断加重,生态环境逐渐恶化;加入遥感表征指标,并基于逐次投影寻踪模型进行的生态环境脆弱度评价能,更好地反映研究区的生态环境脆弱度态势。 In this paper, remote sensing image and statistical data were used to evaluate eco-environment. In this process, some indexes of remote sensing which can reflect ecology environment well were added to evaluation index system and successive projection pursuit method was used to determine index weight. Through the evaluation of ecoenvironment vulnerability in Selangor, Malaysia, it indicates that the coo-environment vulnerability in this region is aggravating and the ecology environment is worse than before. The eeo-environment evaluation method of adding remote sensing indexes and using successive projection pursuit to get the weight is valid.
