| 摘 要： | 利用Landsat遥感数据,计算归一化植被指数（NDVI）并结合空间分析技术,研究了分别代表四川盆地平原和丘陵地貌的眉山市东坡区和仁寿县的NDVI动态演变特征。结果表明,NDVI呈波动变化,总体表现为上升;除1975年外,仁寿县均高于东坡区,即丘陵区均大于平原区;NDVI变化与环境政策、农业政策和农村经济状况密切相关,而丘陵区生态最为脆弱,水是最重要的限制因子。

| Abstract: | Based on Landsat remote sensing data,normalization difference vegetation index(NDVI) was calculated.Combining with spatial analysis technology,NDVI dynamic evolution characteristics of Dongpo District and Renshou County in Meishan City that represent for the plain and hilly landscape of Sichuan Basin respectively were studied.The results showed that NDVI assumed the fluctuation changes and it showed an overall rising performance.Except 1975,NDVI in Renshou County was higher than that in Dongpo Dsitrict,whic... |
