摘要

在对新疆塔城地区白杨河流域2000～2011年间的MODIS-NDVI数据分析的基础上,分析了该区域植被生态的演化,并从地下水因素、土壤因素、人类活动三方面对植被生态演化的影响进行了分析,总结出植被生态变化是自然因素和人为因素相互耦合的结果,其中,自然因素是研究区生态环境演化的主要因素,而近几年不合理的人类活动加剧了研究区生态环境的恶化.%Based on the analysis of MODIS-NDVI at Baiyang River from 2000 to 2011,the ecological evolution of vegetation and its inluence factors are analyzed,it is concluded that the ecological evolution of vegetation is the result of natural factor and human activites,in addition,the natural is the major factor in study area,and the human activites intensified the deteriorate of ecological evolution of vegetation.
