摘要:高标准农田建设项目的实施,在一定程度上促进了区域经济、社会和土地生产能力的可持续发展。选取广东省河源市6个高标准农田项目作为研究单元,在实地踏勘的基础上,建立了基于“流程逻辑”框架4个维度的17个指标构建指标体系,通过德尔菲法和层次分析法确定权重,在此基础上再用熵权法对得到的权重进行修正得到最终权重,利用物元可拓模型计算关联度得出评价结果。结果表明,河源市高标准农田项目绩效水平大体处于”良好”水平,其中4个项目绩效水平“良好”,1个接近“良好”水平,1个处于”优秀”水平的临界线,项目之间的无较大差异。但项目的土地利用提高率,劳动力就业提高率,项目收益人数达标率等评价指标,以及农田基础设施的修筑和维护,是制约该项目绩效等级关联度提高的主要因素。

Abstract: The implementation of high-standard basic farmland construction projects has promoted the sustainable development of regional economic, social and land productivity to a certain extent. Six high-standard basic farmland project areas in Heyuan city were selected as research units. Based on the field survey, 17 index construction index systems were established based on the four dimensions of “process logic” frame. Analytic Hierarchy Process to determine the weight, on this basis, the weight obtained by the entropy weight method is modified to obtain the final weight, and the matter-element extension model is used to calculate the degree of correlation to obtain the evaluation result. The results show that the performance of high-standard basic farmland projects in Heyuan city is generally at a “good” level, four of the projects have “good” performance levels, one approaching a “good” level and one at an “excellent” level with no major differences between the projects. However, the evaluation index of land use improvement rate, labor employment improvement rate and project yield rate of project area, as well as the construction and maintenance of farmland infrastructure in the project area are the main factors restricting the improvement of the project's performance level.

目前,中國工业化和城镇化进程不断加速、越来越多的土地资源被划为建设用地,耕地与基本农田非市场价值被严重忽视,农民对耕地的重视度也日益下降[1]。在新型城镇化和新农村建设背景下,为实现中国耕地与基本农田数量总体稳定、质量稳步提高,土地整治项目的施行与高标准农田建设工作需要加快速度在农村展开[2,3]。
中国的耕地面积近15年来已减少了约667万hm2,而且目前中国存在着许多中、低产田,中、低产田具有很大的粮食增产的潜力,通过高标准农田的建设,可以大大提高耕地质量和农田的粮食生产水平,从而提升耕地的经济效益,提高农民的人均纯收入[4]。……
