【摘要】：土地整治重大工程的实施在保障国家粮食安全、促进城乡统筹发展、改善农村生产生活条件、促进生态文明建设以及全面建成小康社会中发挥着重要作用。就湖北省南水北调汉江沿线土地开发整理重大工程为例,从经济效益、社会效益、生态效益三个方面提取出准则层9项、方案层34项的效益评价指标体系。针对效益评价运用层次分析法(AHP)分别确定不同的指标权重,用多层模糊综合评价法(Multi-FCE)对3大效益分别进行评分,提出指标贡献度的概念,并应用该成果对效益评价进行分析,建立对土地整治重大工程效益的AHP-FCE量化评价模型。研究结果表明:土地整治重大工程的实施能够增加有效耕地面积,提高耕地质量,有效控制水土流失,改善农村人居环境及提高农民生活水平;AHP-FCE模型的评价体系能够较为全面的覆盖土地整治重大工程的各个效益点,客观反映重大工程项目效益实际情况,评价更具科学合理、系统与可靠性;经济效益、社会效益与生态效益具有相互促进或相互牵制的特点。研究对土地整治重大工程效益评价具有一定的理论价值和生产实际意义。
[Abstract]:The implementation of major land regulation projects plays an important role in ensuring national food security, promoting the overall development of urban and rural areas, improving the conditions of rural production and living, promoting the construction of ecological civilization and building a well-off society in an all-round way. Taking the important project of land development and consolidation along the Hanjiang River of the South-to-North Water transfer Project in Hubei Province as an example, the benefit evaluation index system of 9 items of criterion layer and 34 items of scheme layer is extracted from three aspects of economic benefit, social benefit and ecological benefit. In view of benefit evaluation, (AHP) is used to determine different index weights, and multi-layer fuzzy comprehensive evaluation (Multi-FCE) is used to evaluate the three benefits, and the concept of index contribution degree is put forward. The results are used to analyze the benefit evaluation, and the AHP-FCE quantitative evaluation model for the benefit of major land renovation projects is established. The results show that the implementation of major projects of land regulation can increase the area of effective cultivated land, improve the quality of cultivated land, effectively control soil erosion, improve the living environment in rural areas and improve the living standards of farmers. The evaluation system of AHP-FCE model can comprehensively cover all benefit points of major projects of land regulation, objectively reflect the actual situation of benefits of major projects, and the evaluation is more scientific, reasonable, systematic and reliable. Economic, social and ecological benefits have the characteristics of mutual promotion or mutual restraint. The study has certain theoretical value and practical significance for the evaluation of the benefit of major land regulation projects.
