The Evaluation of the City Ecological Environment Quality Based on the Remote Sensing and GIS
Abstract Along with the speeding up of globalization and the rapid development of economy, the global or local ecological environment is suffering the interference and destruction in different extent and brings a variety of ecological environment problems。Based on the study of relevant theories and methods of the ecological environment quality evaluation, this paper established the ecological environment quality evaluation system based on remote sensing。Under the remote sensing and GIS platform, this paper uses remote sensing images and other information to realize acquiring the data of index system, and calculate the ecological environmental quality evaluation of Xuzhou represents years 。And this paper select four issue remote sensing data of 1995,2003,2009 and 2015 years as represented to make the analysis of longitudinal dynamic evaluation for Xuzhou in the past nearly 20 years。Finally this paper summarizes the trend of the change about the ecological environment in Xuzhou recent 20 years ,and analyzes the reasons of changes in ecological environment in Xuzhou city。And gives some corresponding suggestions and according to the change of Xuzhou city ecological environment quality,to provide reference for the relevant departments in Xuzhou on the future ecological environment construction 。
