基于土地整治的项目区耕地资源社会价值评定及变化分析

社会效益评价是土地整治的重要内容之一, 而整治项目区社会价值是土地整治社会效益评价的重要依据, 因此, 开展项目区耕地资源社会价值评定研究对土地整治社会效益评价具有重要意义。本文以河北省曲阳县土地整治项目为例, 通过构建基于土地整治的项目区社会价值评定体系, 借鉴资源经济学的市场价值法、替代市场法、成果参照法及资本还原法等研究方法, 实现土地整治项目区社会价值货币化, 并对整治前后的价值变化进行分析。结果表明, 研究区在土地整治后, 社会保障价值增加32 442.02万元, 但所占总价值比例较整治前有所降低; 社会稳定价值增加1 453.29万元, 人文景观价值增加884.37万元, 且两者占总价值比例均有所升高。耕地总社会价值增加34 779.68万元, 土地整治社会效益显著, 不仅实现了耕作条件的便利、耕地面积的增加, 更实现了生态景观价值的提高。该研究方法对土地整治社会价值评定有借鉴意义, 评价结果可为曲阳县土地整治社会效益评价提供科学依据。

Social value evaluation of cultivated land resources in land reclamation project area

The evaluation of social benefits is an important component of land remediation. Evaluation results of land reclamation project areas lay the crucial basis for evaluating the social benefits of land regulation. Therefore conducting research on land reclamation and social valuation is of tremendous practical significance. A case-study in land rehabilitation project area in Quyang County of Hebei Province was conducted in this research. The social value of cultivated land in the project area was evaluated through constructing a cultivated land value evaluation system based on land reclamation projects and research methods in resource economics, including market value method, alternative market method, achievement reference methods and capital reduction method. In addition, changes and differences in values before and after reclamation were analyzed and conclusions drawn. The results indicated that after land reclamation, the social security value increased by 324.420 2 million RMB. However, the percentage of total value decreased compared with the ratio before the land reclamation. Social stability value increased by 14.532 9 million RMB. Then cultural landscape value increased by 8.843 7 million RMB and both proportions were enhanced. Total social value of cultivated land increased by 347.796 8 million RMB. Land reclamation social benefit was remarkable not only for convenient cultivation conditions and increased cultivated area, but also for enhanced ecology landscape value. This study provided a significant reference for the evaluation of social values of land reclamation. The results also provided the scientific basis for social benefit evaluation of land remediation in Quyang County.
