中文摘要 对广州市2014年ETM遥感影像进行解译,得出植被覆盖度(NDVI指数)、土壤指数(裸图植被指数)及坡度3个环境因子的空间分布结果,再利用综合指数法对归一化后的环境因子进行加权叠加处理,得出广州市自然生态环境最终评价结果。结果显示:广州市总体自然生态环境状况不容乐观,优等级别的地区仅占总面积的0.01%,良好级别的占4.5%,中等级别的占35.79%,差等级别的占59.70%;南部的城市核心区生态环境普遍较差,北部和东北部状况较南部好。重视城市中绿地、绿道的建设,是改善区域环境质量、提高自然生态环境水平的有效途径。

英文摘要 Based on the interpretation of the ETM remotesensing image of Guangzhou in 2014, the spatial distribution results of three environmental factors including vegetation coverage index (NDVI), soil index (naked figure vegetation index) and the slope were collected. By adopting comprehensive index method after normalization of the environmental factors for weighted super position processing, the final ecological environment evaluation results was obtained for Guangzhou. The results showed that overall natural ecological environment in Guangzhou is not in good situation. The area with excellent eco-environment, fine eco-environment, medium eco-environment only accounts for 0. 01%, 4. 5% and 35. 79% of the total area, respectively, while 59. 70% of the total area could be classified as inferior ecoenvironment. In the south of Guangzhou core area, the eco-environment is generally poor, while the north and northeast core area is relatively better. The effort taken to build green spaces and green belt in cities is the effective means toimprove regional environment quality and ameliorate the natural ecological environment.
