【摘要】：土地整理是实现土地资源可持续发展的重要手段之一,科学合理的实施土地效益评价可以为土地整理工作提供理论与实际的指导。本文依托“南充市共兴镇土地整理项目”,综合运用土地资源学、土地规划学、土地经济学、运筹学等多学科理论方法和技术作为支撑,以南充市共兴镇为研究对象,采用特尔斐法选取评价指标并构建土地效益评价指标体系,运用层次分析法确定各评价指标权重,并采用模糊综合评价法,构建效益评价模型,在此基础上,分别从经济效益、社会效益、生态效益和综合效益4个方面对共兴镇土地整理前后的土地整理效果进行评价。本文主要结论包括以下两点：(1)本文分别选取6个经济效益指标,5个社会效益指标,4个生态效益指标构建土地整理效益评价体系,并通过层次分析法得出各评价指标权重,结果表明：农业总产值、绿色植被覆盖率和土地平整率3个评价指标权重相对较大,说明此研究区域在进行土地整理评价工作时这3个指标对评价结果的影响程度最大。(2)共兴镇土地整理后综合效益明显提升,其中整理后的综合效益值为78.88,综合效益评价等级达到“良好”,整理前综合效益评价分值为47.56,综合效益等级为“差”。土地整理的经济效益明显好于整理前,经济效益评价分值由整理前的36.34提高到87.01,评价等级由“差”提升为“优秀”；经济效益评价分值由53.65提高到84.86,社会效益评价等级由“差”达到“良好”级别；生态效益分值由49.07提高到72.61,生态效益评价等级由“差”达到“良好”级别。社会效益和生态效益虽然也明显提高,但同经济效益的大幅增长相比,仍存在不足,相关整理工作需要进行改进。
[Abstract]:Land consolidation is one of the important means to realize the sustainable development of land resources. Scientific and reasonable land benefit evaluation can provide theoretical and practical guidance for land consolidation. Based on the Land consolidation Project of Tongxing Town in Nanchong City, this paper comprehensively uses the theories and techniques of land resources, land planning, land economics and operational research as the support, and takes Tongxing Town of Nanchong City as the research object. The evaluation indexes are selected by Delphi method and the evaluation index system of land benefit is constructed. The weight of each evaluation index is determined by analytic hierarchy process (AHP), and the model of benefit evaluation is constructed by using fuzzy comprehensive evaluation method. The effects of land consolidation before and after land consolidation in Tongxing Town were evaluated from four aspects: social benefit, ecological benefit and comprehensive benefit. The main conclusions of this paper are as follows: (1) in this paper, six economic benefit indexes, five social benefit indexes and four ecological benefit indexes are selected to construct the evaluation system of land consolidation benefit, and the weight of each evaluation index is obtained by analytic hierarchy process. The results showed that the weights of the three evaluation indexes of total agricultural output value, green vegetation coverage and land leveling rate were relatively large. The results show that these three indexes have the greatest influence on the evaluation results in the evaluation of land consolidation. (2) the comprehensive benefit of land consolidation in Tongxing Town is obviously improved. After finishing, the comprehensive benefit value is 78.88, the comprehensive benefit evaluation grade is "good", the comprehensive benefit evaluation score is 47.56, and the comprehensive benefit grade is "bad". The economic benefit of land consolidation was obviously better than that before consolidation, the evaluation value of economic benefit increased from 36.34 to 87.01, and the evaluation grade was raised from "poor" to "excellent". The evaluation value of economic benefit is increased from 53.65 to 84.86, the social benefit evaluation grade is improved from "poor" to "good" grade, the value of ecological benefit is increased from 49.07 to 72.61, and the evaluation grade of ecological benefit is "good" from "poor" to "good". The social and ecological benefits are also obviously improved, but compared with the substantial increase of economic benefits, there are still some shortcomings, and the related collation work needs to be improved.
