摘要
为判别土地整治的可持续性,从土地整治应增加耕地有效利用面积并提高耕地产能、增强土地抵御自然灾害的能力、改善生态环境、具有经济活力与社会可接受性4个方面提出了判别标准。并依此为准则,采用理论分析与专家咨询的方法,构建了土地整治可持续性评估的指标体系与评估模型,并以山东省东明县小井土地整治项目为例进行了案例分析。案例研究结果显示:土地整治前可持续性综合分值为63.20,整治后分值为80.55,可持续性等级由勉强持续上升为中等持续;4项因素的分值分别由21.77、5.61、14.46、21.36提高到26.32、8.53、15.95、29.75,说明土地整治对这4个方面都产生了积极影响。研究结果可以为土地管理部门的土地整治决策提供支持。
In order to discriminate the sustainability of land consolidation（LC）,the criteria for the sustainability of land consolidation were established,which include increasing cropland and enhancing agricultural production（C1）,strengthening disaster bearing capacity（C2）,improving ecological environment（C3）and possessing economic vitality and social acceptability（C4）.According to these criteria,a comprehensive assessment index system and model were defined.And then taking Xiaojing land consolidation project（LCP）in Shandong province of Eastern China as a case study,a total of 15 indicators were selected and the integrated index of sustainability of LC（SLC）was defined to evaluate the sustainability of LC.The results showed the total score of SLC was 63.20 belonging to marginal sustainability before LC and 80.55 belonging to moderate sustainability after LC,which indicated that the sustainability of LC increased after LC.The total integrated index scores of C1,C2,C3 and C4increased from 21.77,5.61,14.46,21.36 to 26.32,8.53,15.95,29.75,respectively.The results can provide a support for the decision-making of the land consolidation authorities.
