    用熵权法和改进TOPSIS模型评价高标准基本农田建设后效应

    Post-evaluation of well-facilitied capital farmland construction based on entropy weight method and improved TOPSIS model

    • 摘要: 规范评价实施效果对科学开展高标准基本农田建设具有重要意义。该文以山地丘陵区3个农业产业化进程梯度差异明显的高标准基本农田建设示范县--重庆市江津区(YQ-I)、铜梁区(YQ-II)、梁平县(YQ-III)为样区,以土地整治项目为样点,选取新型经营主体数量、土地流转规模等10项指标,构建了高标准基本农田建设后经济-社会效应评价指标体系,并将熵权法和改进TOPSIS(technique for order preference by similarity to ideal solution)模型应用于评价。结果发现,在影响经济-社会效应的各项指标中,适度规模化经营面积、项目后期管护农民参与度、农民参与项目施工收入等3项指标处于重要级,指标值变差大、影响强;农民人均农业年收入变化、整治工程村民满意度、项目后期管护措施到位度和农民参与项目施工人数等4项处于边缘级,指标值变差小、影响弱;其余指标处于次要级,影响程度居中。3个样区高标准基本农田建设后经济-社会综合效应与农业产业化进程关系密切,呈现为农业产业化进展快速型的YQ-I>进展加速型的YQ-II>相对缓慢型的YQ-III,效应等级分别为良、中、差;但单方面的经济效应和社会效应具有不平衡性,表现为指标等级分布不平衡、效应等级分布不平衡、研究样区内部不平衡;而随着农业产业化进程加快,经济效应和社会效应之间的差距在逐步缩小,表现为YQ-III、YQ-II和YQ-I中,经济效应贴近度与社会效应贴近度之间的差距依次为22.25、1.21和0.77倍。因此,通过农业产业化,山地丘陵区能有效地利用和发挥高标准基本农田建设的支撑作用,并通过新型经营主体更好地统筹高标准基本农田的建设与后续管护;而基于熵权法和改进TOPSIS模型的评价方法,能够有效用于高标准基本农田建设后经济-社会效应评价。

       

      Abstract: Abstract: In the context of a large-scale well-facilitied capital farmland construction, scientifically evaluating its effect and influence of post-implementation will be of great significance. We chose Jiangjin District(YQ-I), Tongliang District(YQ-II), and Liangping County(YQ-III), three demonstration counties of well-facilitied capital farmland construction from Chongqing Municipality as study areas, which were characterized by obvious gradient difference of agricultural industrialization.We also chose typical land consolidation projects as survey samples from each county. Taking economy and society effect as the core, and by the aid of entropy weight method and improved TOPSIS model, we built the post-evaluation index system and evaluated economy and society effect of three sample areas. In the evaluating index system, number of the new operators(C1), scale of land circulation(C2), area of scale management(C3), changes of peasants' annual farm income per person(C4), and changes of per area output(C5) were used as indicators of economy effect. Income of peasants' participation in the project(C6), number of peasants' participation in the project(C7), degree of peasants' satisfaction for the project implementation(C8), degree of peasants' participation late in the project(C9), and degree of nursing measures' implementation late in the project(C10) were used as indicators of society effect. The results showed that the index weight order of economy effect was C3(0.3984)>C2(0.2706)> C1(0.1798)>C5(0.1337)>C4(0.0175), and the index weight order of society effect was C9(0.4006)>C6(0.3999)>C8(0.0995)>C10(0.0919)> C7(0.0081). Through the classification of index weight importance, C3, C9, and C6 were classified as importance with the large variation and strong impact; C4, C8, C10, and C7 were classified as edge with the small variation and weak impact; the rest, as less importance with moderate impact. Evaluation results of the three study sample areas had an obvious relationship with the process of agricultural industrialization, order of the comprehensive effect was YQ-I(rapid advance)> YQ-II(accelerated advance)> YQ-III(relatively slow advance), and the effect level was good, medium, and poor respectively. And in single effect, there were disequilibrium features between economy effect and society effect, which included disequilibrium of index classification, effect classification, and the study sample area inside. However, accompanied by speeding up agricultural industrialization process, the gap between economy effect and society effect was closing from 22.25 times of YQ-III to 1.21 times of YQ-II, 0.77 times of YQ-I. Based on analysis of evaluation results, we considered that, in addition to following the generalized target, content and technical requirements, giving play to the supporting role of well-facilitied capital farmland construction in mountain and hilly area, should also definitely aim at practical demand of regional agricultural development. Among the three studied areas, experience of YQ-I was worth learning, and its specific practice consisted of three steps. First step was to discover regional advantages of agricultural resources and industry.Second step was to combine well-facilitied capital farmland construction with land circulation, agricultural industrialization and scale management.The third step was to transform farming plots, constructed supporting agricultural infrastructure according to demands of different agricultural industries and moderate scale management. By means of the three steps, YQ-I answeredthe needed-facilitied capital farmland construction on how to improve agricultural production conditions, and how to construct agricultural infrastructure, especially realized benign interaction between farmland construction and agricultural industrialization. However, problem of YQ-II still needed to rethink. The key was to pay more attention to new agricultural operators' role in well-facilitied capital farmland construction, and built a mechanism from point-based nursing experiences and succeeded practice to surface-based popularization and application. Lessons of YQ-III should be remembered. Well-facilitied capital farmland construction cannot be divorced from agricultural industrialization, and removed from agricultural structure adjustment, land circulation, moderate scale management, and new operators' development. In conclusion, under the guide of agricultural industrialization mountain and hilly area can be able to effectively utilize the supporting role of well-facilitied capital farmland construction, and realized better successor-nursing by means of new operators. Meanwhile, the evaluation method based on entropy weight method and improved TOPSIS model can be also effectively used to evaluate economy and society effect of well-facilitied capital farmland construction.
