基于MODIS遥感数据和GIS的山东省生态环境状况评价

本文利用山东省MODIS遥感影像，以监督分类方法进行了土地利用／覆被分类，通过GIS的空间分析功能提取出生物丰度指数、植被覆盖指数、水网密度指数、土地退化指数、环境质量指数等评价信息，利用构建的生态环境状况指数（EI）模型，进行了山东省生态环境状况的评价。研究结果表明，山东省生态环境状况整体较好，优、良面积占总面积的61．1％，但同时存在环境污染、土地退化、水资源短缺等问题，生态环境较差、差的面积占16．2％。该研究探索了MODIS数据和GIS技术相结合的生态环境状况评价方法，对区域生态环境的保护和改善具有积极意义。

Evaluation of the ecological environment of Shandong Province using MODIS data and GIS platform

MODIS image centered about Shandong Province, classification of land use/land cover by supervised method, extraction of the indexes of biological abundance, vegetation cover, water density, land degradation, environmental quality by using spatial analysis functions in GIS and other relevant information were used to evaluate the ecological environment of Shandong Province by establishing an ecological and environmental situation index (EI) model. From the results, the overall ecological environment of Shandong Province is good, with 61.1% of the total area classed as excellent or good. However, other problems like environmental pollution, land degradation and water shortages exist, with 16.2% of the total area classed as worse. The study has positive implications on the protection and improvement of the regional ecological environment.
