济南市耕地多功能性时空演变及优化调控研究
Study on Spatio-temporal Evolution and Optimal Regulation of Cultivated Land Multifunctionality in Ji'nan City
摘要
Abstract
The research on the multi-functionality of cultivated land is of great significance to the protec-tion and sustainable utilization of cultivated land.Taking Ji'nan city as a research area,a grid-scale multi-functional evaluation method system of cultivated land has been constructed,the spatio-temporal evolu-tion characteristics of multi-functionality of cultivated land in Ji'nan city from 2013 to 2023 has been sys-tematically analyzed,and the zoning has been optimized.It is showed that spatial distribution of various functions and multi-functionality of cultivated land in Ji'nan city is similar from 2013 to 2023,and spatial distribution pattern is high in the north and low in the south.During the study period,the multi-func-tionality of cultivated land in Ji'nan will decrease first and then increase.In terms of specific functions,ex-cept for habitat maintenance function,other functions show a trend of weakening first and then strengthe-ning,while habitat maintenance function shows a trend of strengthening first and then weakening.The protection of multi-functionality of cultivated land in Ji'nan city should start from the perspective of the"trinity"of quantity,quality and ecology,and formulate protection and development policies according to different functional areas of cultivated land.关键词
