Study on Land Use Transformation and Ecological Environment Effects in Yulin City
[Purposes]By analyzing the characteristics of land use transformation and quantitatively ex-pressing the effects of ecological environment caused by land use transformation,this study provides a reference basis for promoting the sustainable development of the"three living"space in Yulin City,carry-ing out regional land space planning,resource conservation,and ecological environment protection.[Methods]The land use data of Yulin City in 2000,2005,2010,2015 and 2020 were selected,the lead-ing functions of land use were divided according to"production-life-ecology",and the land use transfer matrix was used to study the land use situation of Yulin City,and the ecological environment quality in-dex and ecological contribution rate of land use transformation were calculated to quantitatively analyze the ecological environment effect of Yulin City.[Findings]From 2000 to 2020,the area of production land and ecological land in Yulin City decreased,while the area of living land increased;The change of land use center is relatively stable,and the change of living land center is obvious.The ecological envi-ronment quality index of Yulin City increased from 0.489 0 in 2000 to 0.493 2 in 2020,and the ecologi-cal environment quality showed an upward trend.There are two kinds of ecological environment improve-ment and deterioration in Yulin city at the same time,but the trend of improvement is slightly greater than the trend of deterioration.[Conclusions]Yulin City should strengthen ecological protection and pro-mote the further improvement of ecological environment quality.
