福建省耕地生态压力与农业经济的脱钩分析

Decoupling Analysis of Cultivated Land Ecological Pressure and Agricultural Economy in Fujian Province

运用“国家公顷”生态足迹模型,计算并分析福建省2006—2020年的人均耕地生态足迹、人均耕地生态承载力和耕地生态压力指数。选用Tapio脱钩模型对耕地生态压力和农业经济的脱钩关系进行评价。结果表明,2006—2020年,福建省人均耕地生态足迹降低了20.0%,人均耕地生态承载力降低了49.3%;耕地仅在2006年存在生态盈余,其余年份都出现生态赤字,且人均生态赤字呈现扩大趋势,2020年达到2007年的4.3倍;耕地生态压力指数15年里上升了60%;耕地生态压力和农业经济的脱钩状态以强脱钩和弱脱钩为主,个别年份具有不稳定性。

The per capita ecological footprint,per capita ecological capacity,ecological pressure index of cultivated land in Fujian from 2006 to 2020 were calculated and analyzed by using the “National Hectare” ecological footprint method.Tapio decoupling model was used to evaluate the decoupling relationship between cultivated land ecological pressure and agricultural economy in Fujian from 2006 to 2020.The results show that:from 2006 to 2020,the per capita ecological footprint of cultivated land in Fujian decreased by 20.0%,the per capita ecological capacity of cultivated land in Fujian decreased by 49.3%.Only in 2006,there was an ecological surplus in cultivated land,and there was an ecological deficit in other years,and the per capita ecological deficit showed an expanding trend,which in 2020 was 4.3 times that of 2007.During the fifteen years,ecological pressure index of cultivated land increased by 60%.The decoupling state of cultivated land ecological pressure and agricultural economy was mainly strong decoupling and weak decoupling,with instability in individual years.
