摘要
基于网格尺度揭示2010-2020年长株潭都市圈耕地生产、生活、生态、文化功能的时空分异特征,探究耕地多功能间的权衡与协同关系并进行耕地功能分区。研究发现,2010-2020年长株潭都市圈耕地综合功能提升,呈现“西高东低”的空间格局:耕地生态功能以中、较低等级为主,呈现“西高东低”的空间特征;生产功能以较高等级为主,较高等级区主要分布在西部及中部;生活功能较弱,空间不均衡性显著;文化功能的中等级区占比较大。2010-2020年长株潭都市圈耕地生态—生活功能、生活—生产功能为权衡关系,且权衡关系呈增强态势;生态—文化功能、生态—生产功能、文化—生产功能为协同关系,且协同关系呈增强态势;文化—生活功能亦为协同关系,但协同关系呈减弱态势。2020年长株潭都市圈耕地功能区域分为生产主导区、均衡发展区、生产生态区以及生产文化区。在此基础上,提出促进长株潭都市圈耕地利用转型的策略建议,以期助力乡村全面振兴。
Based on the grid scale,this study reveals the spatio-temporal differentiation characteristics of the production,living,ecological and cultural functions of cultivated land in the Changsha-Zhuzhou-Xiangtan Metropolitan Area from 2010 to 2020,explores the trade-off and synergistic relationships among the multiple functions of cultivated land,and conducts the functional zoning of cultivated land.Research findings show that from 2010 to 2020,the comprehensive functions of cultivated land in the Changsha-Zhuzhou-Xiangtan Metropolitan Area improves,presenting a spatial pattern of"higher in the west and lower in the east":the ecological functions of cultivated land are mainly at medium and lower grades,showing a spatial feature of"higher in the west and lower in the east";the production functions are mainly at higher grades,and the higher-grade areas are mainly distributed in the western and central regions;the living functions are relatively weak,and the spatial imbalance is significant;in terms of cultural functions,the proportion of medium-grade areas is relatively large.From 2010 to 2020,the ecological-living function and living-production function of cultivated land in the Changsha-Zhuzhou-Xiangtan Metropolitan Area are both in the trade-off relationship,and the trade-off relationships show an strengthening trend;the ecological-cultural function,ecological-production function and cultural-production function are all in the synergistic relationship,and the synergistic relationship is showing an strengthening trend;the cultural-living function is also in a synergistic relationship,but the synergistic relationship is weakening.In 2020,the cultivated land functional areas of the Changsha-Zhuzhou-Xiangtan Metropolitan Area are divided into production-leading areas,balanced development areas,production-ecological areas and production-cultural areas.Hence,strategic suggestions for promoting the transformation of cultivated land utilization in the Changsha-Zhuzhou-Xiangtan Metropolitan Area are put forward,with the aim of contributing to the comprehensive revitalization of rural areas.
