基于NDVI的农牧交错带典型地区时空动态特征研究--以吉林西部为例
The Temporal and Spatial Dynamic Characteristics of Typical Area in the Farming-pastoral Ecotone Based on NDVI-A Case of Western Jilin Province
摘要
Abstract
Objective] To discuss the temporal and spatial dynamic characteristics of typical area in the farming-pastoral ecotone based on NDVI.[ Method] Based on the MODIS NDVI data sets from 2000 to 2010, the spatial distribution of NDVI for the above-ground vegetation in typical area of the farming-pastoral ecotone in western Jilin Province was studied by spatial autocorrelation analysis and trend analysis methods. [Result] NDVI for the vegetation in the western Jilin Province performed a significantly rising trend in the growing season during 2000-2010. spatial distribution of aboveground vegetation in research region showed a positive correlation, but there was a fragmented distribution in some special areas, indicating the general integrity of vegetation distribution.[ Conclusion] This research provides scientific basis for the rational protection of nature.关键词
