摘要
耕地利用存在大量不计入生产成本却由社会承担的社会成本。以耕地的主要类型旱地为例,探讨其社会成本的产生途径及表现形式,并针对不同表现形式的社会成本运用不同方法构建量化测算模型。以沈阳市苏家屯区为例进行实证分析,结果表明:苏家屯区旱地利用社会成本具体表现为水土流失、温室效应、水体富营养化、饮用水源污染和农田生态系统生物多样性降低;2010年苏家屯区旱地利用社会成本总计为1270.53万元,单位社会成本为672.06元/hm2。
Abstract： In farmland cultivation a lot of costs have beet not calculated as production cost but borne by society. Such costs are called social cost. Dry land, the main type of farmland, is taken for example to explore the generative origin and manifestations of social cost. Quantitative calculat：[on models are built for different forms of social cost with different methods. In the process, the dry land of Sujiatun, a Shenyang district, is taken for example to make an empirical research. The results show that Lhe social cost generated by the dry land cultivation in Sujiatun manifests itself as soil erosion, greenhouse effect, water eutrophication, the pollution of the drinking water sources and the reduction of the farmland ecosystem bio-diversity. The social cost generated by the dry land cultivation in Sujiatun in 2010 is ~12,705,300 totally, namely,Y672.06 / hm1.
