摘　　要：为科学认识湘赣边县域“三生空间”格局演变,促进区域发展,以茶陵县为研究区,基于茶陵县2000年、2010年和2020年土地利用数据,采用土地利用动态度、土地转移矩阵、核密度估计法,揭示茶陵县“三生空间”格局分布与演变特征。结果显示:(1)茶陵县“三生空间”分布中,生态空间分布最广;生产空间聚集性较强,主要位于茶陵县中部至西南部,呈线状分布;生活空间主要分布在县城地区。(2)茶陵县“三生空间”二级分类中单一土地利用动态度最高的是水域生态空间,其次为城乡生活空间,而林地生态空间是唯一单一土地利用动态度为负的二级分类类型,整个研究期内综合土地利用动态度均为正。(3)2000—2020年,茶陵县共有179.47 km~2空间面积发生了转换,其中生产空间主要转为生态空间,生活空间和生态空间均主要转为生产空间,二级分类中林地生态空间转为农业生产空间的面积最大。(4)茶陵县“三生空间”转入转出面聚集程度较高,其中生态空间的转出密度值最高,为1.72,生产和生活空间转入的高值区分布在中心城区及周边乡镇,生态空间转入区则多分布于虎踞、高陇、界首等外围乡镇。在转出的空间分布中,生产和生活空间较为分散,生态空间转出区集中于中心城区及周边的枣市镇、严塘镇和舲舫乡。研究结果说明2000—2020年茶陵县“三生空间”格局变化明显。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 km’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
