| 摘 要： | 耕地资源可持续利用评价中的难点在于生态可持续评价指标的确定及其可行性，由于长期连续的耕地性状数据难以获取，农业用地生态可持续性评价往往属于定性描述而非定量化的结果。本文提出了耕地可持续利用评价指标体系，将之划分为生态、经济和社会三个层次，建立了耕地类基本生产力模型和影子价格模型，对技术进步因素作了剔除，并根据苏州吴江市1987～1997年的耕地利用状况，定量评价了其耕地利用方式的可持续性。

| Abstract: | The establishment of an ecological index system for assessment of sustainability of cultivated lands has always been difficult due to lack of long-term cont inuous data of land properties.So usually the assessment results are qualitative instead of quantitative.In this essay an index system for assessment of sustainability of cultivated land is proposed and followed by a case study of Wujiang City, Suzhou City.The index system is divided into three levels, i.e.ecological, economic and social levels.To get a quantitative result in ecological assessment we set up a quasi-basic productivity model and a shadow price model and eliminate the contribution of technique improvement.Besides we assess the economic sustainability and the influence of agricultural policies. |
