基于RS和GIS的山东省植被覆盖的时空演变特征及其成因研究

Vegetation Covering Spatial-Temporal Changes in Shandong Province Based on RS and GIS

摘要: 当前山东省处于快速发展阶段，经济的高速增长以及粗放的发展模式使得山东省的土地利用方式以及植被覆盖发生了深刻变化。本论文以山东省为研究区域，利用2002年至2011年1 km分辨率的MODIS NDVI数据，在ENVI技术的支持下，分析了山东省植被覆盖变化情况。研究结果表明气候干旱、多元化开发以及农业耕种是导致山东省植被覆盖变化的主要原因，山东省整个区域的植被指数空间分布具有明显的地域特征，MODIS-NDVI植被指数可以用来对不同的植被种类进行监测，还可以对同种植被的不同生长期变化进行监测，本研究的研究结果可以为政府环境管理经济规划等工作提供基础信息支持。

Abstract: Shandong Province is in the stage of rapid development at present. Rapid economic growth and extensive development model make the land use and vegetation cover undergo profound changes in Shandong Province. Based on the MODI S NDVI data with 1 km resolution, the vegetation cover changes of Shandong Province from 2002 to 2011 were analyzed in this paper supporting by the ENVI technology. The results showed that drought, fixed assets investment and crop planting area may be the main reasons for vegetation coverage changes of Shandong Province. Vegetation index has an obvious spatial difference in Shandong and MODIS-NDVI can be used to monitor different vegetation types and their growing periods. This paper can provide a basic information support for governing environment and economic planning.
