长三角耕地—粮食生产时空演变与区域协同治理
The spatial-temporal evolution and regional collaborative governance of farmland and grain production in the Yangtze River Delta
摘要
Abstract
Cultivated land resource is vital for food security and the high-quality integrated development of the Yangtze River Del-ta region.This paper combined the centroid,elasticity coefficient,and carrying capacity models to analyze the spatiotemporal interactions of cultivated land and food production in this region from 2009 to 2023.The results showed that:① Spatially,cultivated land endow-ments and food production capacities were greater and higher in the north than in the south,with significant regional differences.②Temporally,total cultivated land first decreased and then increased,high-quality cultivated land continued to decline,food output steadily rose,and the centers of gravity for cultivated land and food production shifted to northern Anhui.③ The coupling relationship between cultivated land and food production generally improved,with food production becoming more dependent on cultivated land.④Overall cultivated land carrying capacity remained balanced but with large internal differences,highlighting the need for enhanced culti-vated land protection and regional cooperation.关键词
