【目的】归一化植被指数是反映森林植被变化的重要参数,分析湖南省NDVI(Normalized Differential Vegetation)的变化趋势及其影响因子,对准确评估该省2000-2017年间植被恢复情况,分析气候驱动力因素具有重要意义。【方法】在美国国家航空航天局卫星平台完成NDVI数据下载,运用戈达德航天中心下载的2000-2017年NDVI数据集,采用趋势分析的方法分析NDVI的变化。在中国气象科学数据共享服务网下载2000-2017年间降水、温度数据,结合同期NDVI数据,分析NDVI与降水、温度的相关关系。【结果】1)年际、季节NDVI均值增长趋势达到显著水平(P

【Objective】As a major forestry province, Hunan has been committed to the restoration of forest vegetation after the period of large-scale destruction of vegetation.Normalized Differential Vegetation is an important parameter to reflect the changes of forest vegetation, so it is of great significance to analyze the changes of NDVI (Normalized Differential Vegetation)in Hunan province to evaluate the changes, driving factors of vegetation in the past 20 years.【Method】Complete NDVI data download on NASA satellite platform, NDVI data set from 2...
