摘要
生态环境质量直接影响着人类的生产生活环境,甚至整个生态系统,为探讨如何快速便捷的获取生态环境质量信息,以Landsat 8 OLI_TIRS卫星数据为基础,利用常用的绿度、湿度、热度和干度等4种生态指数,通过主成分分析法获得遥感生态指数,用于评价生态环境质量,并将其分为5级,同时结合当地的自然环境、城镇开发、居民活动等因素综合评价岳麓区的生态环境质量;对提升城镇区域及城郊过渡区域的生态质量和加强生态环境的建设和保护提出了有效建议。
The quality of the ecological environment directly affects the production and living environment of humans,even the entire ecosystem.To explore how to quickly and conveniently obtain information on the quali-ty of the ecological environment,this article uses Landsat 8 OLI_TIRS satellite data as a basis,obtaining the remote sensing ecological index through principal component analysis,using four commonly used ecological in-dicators,namely,Normalized Difference Vegetation Index,humidity,Land Surface Temperature Indext and Normalized Difference Siccative Index,to evaluate the quality of the ecological environment,and it is divided into five levels.Combined with factors such as the local natural environment,urban development and resident activities,a comprehensive evaluation of the ecological environment quality in Yuelu District has been made.At the same time,effective suggestions are put forward for improving the ecological quality of urban areas and suburban transition areas and strengthening the construction and protection of the ecological environment.
