利用耕地功能指数、功能优势指数等分析 2010-2020 年湖南省武陵山片区耕地多功能的时空演变趋势,探讨功能视角的片区耕地分区优化措施.结果表明:耕地功能时间演变存在差异,总体持续增长,文化、生产、生态安全、社会保障功能的变化率依次降低;耕地功能呈现明显的空间异质性,总功能由 2010 年的东高西低、北高南低演变为 2020 年的 4 个高值中心;生产功能由北低南高演变为高值集中于东部;社会保障功能由东高西低演变为高值局部凸出、中等值普遍分布;生态安全功能由四周高、中间低演变为极高值三足鼎立,文化功能由北高南低演变为极高值和高值贯穿全域.将研究区划分为生产-生活、生态-文化、生产、文化和生活-生态功能优势区等5类.
Cultivated land function index and function advantage index were collected to analyze the spatiotemporal variation trend of cultivated land multi-functions and to find out zoning optimization strategies in Wuling Mountain Area of Hunan Province.The results were as follows:the temporal changes of cultivated land multi-functions were different and they all showed growth trends.The change rates of cultural,production,ecological security and social security functions decreased successively.It had obvious spatial heterogeneity for the cultivated land functions.The total function had changed from higher in the east and lower in the west,higher in the north and lower in the south in 2010 to four higher centers in 2020.The production function had changed from lower in the north and higher in the south to the higher centers concentrated in the east.The social security function had changed from higher in the east and lower in the west to higher centers local protrusions and medium areas widespread distribution.The ecological security function had changed from lower in the center and higher in the peripher to highest and higher areas distributed throughout the region.The research area could be divided into five types,namely that production-living,ecological-cultural,production,cultural,and living-ecological functions advantage areas.
