Analysis of Pattern Evolution Characteristics of"Production-Living-Ecological Space"in Chaling County,Hunan Province
To scientifically recognize the evolution of"Production-Living-Ecological space"pattern in counties on the border of Hunan and Jiangxi provinces and to promote regional development.Chaling County was taken as the study area,and based on the land-use data of Chaling in 2000,2010,and 2020,the distribution and evolution characteristics of"Production-Living-Ecological space"pattern revealed by utilizing the land-use dynamic degree,land transfer matrix,and kernel density estimation method.The results were as follows:(1)In the distribution of the"Production-Living-Ecological space"in Chaling County,the ecological space was the most widely distributed,the production space was highly agglomerate,mainly located from the central to the southwest with a linear distribution;the living space was mainly distributed in the city proper of the county.(2)In the secondary classification of"Production-Living-Ecological space"in Chaling County,the highest land use dynamic degree was water ecological space,followed by living space in urban and rural areas.Forest ecological space was the only secondary classification type a with negative dynamic degree,and the comprehensive dynamic degree of land use was positive throughout the study period.(3)A total of 179.47 km2 of spatial area was converted in Chaling County from 2000 to 2020,of which production space was mainly converted into ecological space,the living space and ecological space were mainly converted into production space,and the area of forest land ecological space converted to agricultural production space was the largest in the secondary classification.(4)In Chaling County,the aggregative degree of the transfer-in and transfer-out was relatively high,and the transfer-out density of ecological space was the highest(1.72).The high-value areas of production and living space transfer-in areas were distributed in the central urban area and surrounding towns,while the ecological space transfer areas were mostly distributed in the peripheral towns such as Huju,Gaolong,Jieshou,etc.In the distribution of transfer-out,the production and living space were scattered,and the ecological space transfer-out area was concentrated in the central urban and the surrounding Zaoshi,Yantang,and Lingfang Township.The research results indicate that there has been a significant change in the pattern of"Production-Living-Ecological space"in Chaling County from 2000 to 2020.
