随着城镇化、工业化的快速推进,我国城乡建设用地快速扩展使农用地保护面临巨大挑战,从经济机制上防止土地过度非农化尤为重要。该文对土地非农化生态价值损失过程机制进行了理论探索,建立了价值损失估算方法,并以江汉平原为例进行案例分析。研究表明:单纯的市场机制没有考虑土地非农化造成的生态价值损失,无法实现土地资源最佳配置,非农化规模偏大;土地非农化生态价值损失巨大,1987-2010年江汉平原因此累计损失73 692.11万元,人均承担49.25元;不同类型土地的生态价值损失强度有所差异,每公顷的自然保留地、水域、林地、草地、耕地非农化价值损失分别为2.459 8万元/a,2.036 7万元/a,1.262 9万元...

With rapid development of urbanization and industrialization,urban-rural construction land in China becomes a big challenge in conserving agricultural land.This study insists that it is a good point to prevent non-agriculturalization in land-use through economic regulating mechanism.This paper explored theories about ecological value loss mechanism during the process of nonagriculturalization of arable land and established an estimate method on ecological loss.Jianghan Plain was chosen as a case study in order to verify the estimate method.The ...
