%X 地球环境系统的恶化威胁到人类的生存发展和自然资源的可持续性，必须加强对地球环境系统变化的监测与管理，这已成为科学研究中备受关注的热点领域。本文将2011~2021年浙江省的植被指数作为研究对象，探究浙江省NDVI时空变化特征及其对地形因子、土地利用因子的响应变化规律。结果表明：(1)研究期间，浙江省植被指数有轻微下降趋势，主要与城市化进程、农业生产活动受到抑制有关；(2) 研究期间，浙江省NDVI具有明显的海拔梯度差异特征，坡度、坡向对植被变化影响不大；(3) 浙江省土地利用类型以农田、森林、水域和不透水地表为主，NDVI的变化与土地利用类型转换有关。<br />
The deterioration of the earth’s environmental system threatens the survival and development of human beings and the sustainability of natural resources. It is necessary to strengthen the monitoring and management of the changes of the earth’s environmental system, which has become a hot topic in scientific research. In this paper, the vegetation index of Zhejiang Province from 2011 to 2021 is taken as the research object to explore the temporal and spatial variation characteristics of NDVI in Zhejiang Province and its response to topographic factors and land use factors. The results show that: (1) during the study period, the Zhejiang NDVI has a slight decline, which is mainly related to the inhibitory process of urbanization and agricultural production activities; (2) during the research, NDVI in Zhejiang Province has obvious characteristics of elevation gradient differences, and the impact of slope and slope has little effect on the change of vegetation; (3) the land use type in Zhejiang Province is mainly farmland, forests, waters and impermeable surfaces. The changes in NDVI are related to the conversion of land use types.
