| 摘 要： | 为了实现经济的可持续发展,推动生态文明建设迈向更高台阶,生态环境质量状况越来越受到人们的关注。本文以新余市为研究区域,选取2002、2013和2017年Landsat影像,提取植被覆盖信息、土地覆被信息和土壤侵蚀信息。在建立生态环境评价指标体系的基础上,采用GIS和RS相结合的技术手段,计算出研究区域的生态环境状况指数(EI),分析和监测研究区域的生态环境质量状况。结果表明:2002年新余市的EI为75.96,为优水平,说明新余市的生态环境非常适合人类的生存;2013年新余市的EI为67.74,为良好水平,生态环境明显变差;2017年新余市的EI为70.71,也为良好水平,但生态环境有略微变好趋势。研究结果使人们对新余市的生态环境现状有一个很好的了解,为新余市的生态建设提供一个参考依据。

| Abstract: | In order to realize the sustainable development of economy and promote the construction of ecological civilization to a higher level,the quality of ecological environment has attracted more and more attention.Taking Xinyu City as the research area,remote sensing images of Landsat in 2002,2013 and 2017 were selected to extract vegetation coverage information,land cover information and soil erosion information on the basis of establishing the ecological environment evaluation index system,the ecological environment sta-tus index(EI)of the study area is calculated by using the combination of GIS and RS,and the ecological environment of the study ar-ea is dynamically monitored and analyzed.The results show that:the EI of Xinyu City was 75.96,which was the excellent level in 2002,indicating that the ecological environment is very suitable for human survival;The EI of Xinyu City was 67.74,which was a good level in 2013,and the ecological environment was obviously worse;The EI of Xinyu City in 2017 was 70.71,which is also a good level,but the ecological environment has a slightly better trend.The research results make people have a good understanding of the ecological environment and provide a reference for the ecological construction of Xinyu City. |
