基于遥感技术的江西省植被生态环境初探
Initial Research on Vegetation Ecological Environment in Jiangxi Based on Remote Sensing Technique
摘要
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 summers contribution to the vegetation change was the greatest.关键词
