| 摘 要： | 应用美国国家航空航天局最新的全球植被变化数据(GIMMS),通过计算每月NDVI变化率,并对研究区进行一元线性回归模拟,分析了江西省1982～2006年的地面植被覆盖情况。结果表明:25年来,植被覆盖呈微弱减少趋势,表明江西省植被生态环境有微弱下降的趋势;从季节变化看,江西省植被覆盖在春季呈增加趋势,夏、秋、冬季均呈下降趋势,其中夏季对植被覆盖总变化量的贡献最大。

| Abstract: | The change rate of monthly Normalized Difference Vegetation Index（NDVI） is calculated by using the data of Global Inventory Modeling and Mapping Studies（GIMMS） of NASA from 1982 to 2006,and the vegetation cover of earth surface in Jiangxi is analyzed by the unary linear regression simulation model.The main results were as follows： in recent 25 years,NDVI values showed a descending trend in the studied area,indicating that the macrocosm status of vegetation environment in Jiangxi was deteriorating;in spring,NDVI values showed an increasing trend,but did decreasing trend in summer,autumn and winter,and the summer＇s contribution to the vegetation change was the greatest. |
