The quality of the habitat is deteriorating continuously, and the degradation is serious around the city and along the main river basins.[Conclusion] The habitat quality in the central and western regions of Jilin Province has declined seriously, thus, more attention should be paid on the protection and rational utilization of city surrounding zones and water systems. %R 10.13961/j.cnki.stbctb.2020.06.022 %U http://stbctb.alljournal.com.cn/stbctb/home %1 JIS Version 3.0.0
