摘要
通过遥感解译分析沈阳市2011年-2018年土地利用空间分布,对该区域生态环境状况进行评价,分析变化趋势及主要影响因素。结果表明,沈阳市2011年-2018年生态环境状况级别均为良,逐年变化值均小于1,属无明显变化级别,生态环境质量状况总体稳定。期间,生态环境状况指数及变化值与土地胁迫指数、污染负荷指数相关性较大,受污染物排放量、土壤侵蚀面积、降水总量等指标要素影响较大。
Through remote sensing interpretation and analysis of the spatial distribution of land use in Shenyang from 2011 to 2018,the ecological environment of the region was evaluated,and the change trend and influencing factors were analyzed.The results show that from 2011 to 2018,the ecological environment of Shenyang is in good condition,and the annual change value is less than 1.There is no obvious change level,and the ecological environment quality is generally stable.During the period,the index and change value of the ecological environment condition have a great correlation with the land stress index and pollution load index,and are greatly affected by the pollutant emission,soil erosion area,total precipitation and other indicators.
