湖南省"三生空间"的时空变化及生态环境质量
Spatiotemporal Changes and Ecological Environmental Quality of the "Three Spaces" in Hunan Province
摘要
Abstract
[Objective]Economic development and urbanization have led to changes in the structure and function of production,living,and ecological space(called"three spaces"),thereby causing chan-ges in the quality of regional ecological environment.Studying the spatiotemporal changes and ecological environmental effects of the"three spaces"can provide reference for scientific management of land use in the"three spaces".[Method]The land use data of five periods in 2000,2005,2010,2015 and 2020 were selected to analyze the spatiotemporal changes and characteristics of the"production-life-ecology"spatial land use function transformation in Hunan Province by using the transfer matrix and the shift of gravity,and the ecological environmental quality index evaluation model was used to comprehensively measure the regional ecological environmental quality.Combined with the ecological contribution rate of land use transformation,the ecological and environmental effects of the change of the"three spaces"in Hunan Province from 2000 to 2020 were quantitatively analyzed.[Result](1)From 2000 to 2020,the agricultural production space,forest ecological space and grassland ecological space in Hunan Province showed a decreasing trend,mainly in the conversion of production space and ecological space.(2)In the production space,the shift distance of the center of gravity in industrial and mining production space was the largest(32 853.9 m),and the smallest shift distance were agricultural production space(587.53 m)and forest ecological space(523.01 m).(3)During the study period,the eco-environmental quality index decreased first and then increased,with an overall decrease of about 6.7%.In space,it showed the distribution pattern of"high in the west and low in the north,gradually increasing from north to south".[Conclusion]The quantity and spatial change of the"three spaces"have affected the ecological environmental quality in Hunan Province.The conversion of forest land ecological space into agricultural,industrial and mining production space and urban living space are the main factor of the decline of ecolog-ical environmental quality in the prior period,and the conversion of agricultural production land into for-est land and other ecological land is the main reason of the improvement of ecological environmental qual-ity in the later period.关键词
