基于熵权可拓物元模型的农村土地整理项目绩效评价

在剖析农村土地整理项目绩效内涵的基础上,从决策绩效、实施绩效、运营绩效三个方面构建了评价指标体系,建立了农村土地整理项目绩效评价的熵权可拓物元模型,并以苏州市农村土地整理项目为例进行了实证研究。研究结果表明:(1)苏州市农村土地整理项目绩效水平参差不齐,项目之间的差异较大:两个项目绩效处于"良好"水平,三个项目绩效接近"良好"水平,一个项目绩效接近"较差"水平;(2)植被覆盖提高率、粮食产能提高量、农地年收入增加量、土地利用提高率、灌溉面积增加率、防护林网密度、机耕面积增加率等指标是农村土地整理项目绩效水平提升的关键制约因素。(3)应进一步加强农村土地整理项目管理建设,建立景观生态型农村土地整理模式,健全农村土地整理后期管护机制,合理实施农地规模经营,优化种植结构等,进而促进农村土地整理项目绩效水平不断提升。

Achivement Evaluation of Rural Land Consolidation Project Based on Entropy-weighted Extension Matter-element Model

On the basis of defining the meaning of rural land consolidation project achivements, the evaluation index system was constructed from decision-making achivements, implementation achivements and operation achivements, and the entropy-weighted extension matter-element model for evaluation on rural land consolidation project achivements was established, then an empirical analysis was conducted on the projects of Suzhou City. Results showed that:(1) The achivements levels of rural land consolidation project in Suzhou City are quite different. Two projects' achivements levels are "good", that of three projects are close to "good", and one project is close to "poor".(2) The major obstacle factors of rural land consolidation project achivements include the raising rate of vegetation coverage, the raising amount of grain productive capacity, the increasing amount of annual income for farmland, the raising rate of land use, the increasing rate of the irrigated area, the density of shelter forest network, the increasing rate of mechanized farming area, and so on.(3) The rural land consolidation project achivements could be continuously improved by strengthening the rural land consolidation project management, establishing rural land consolidation mode based on the landscape ecology, sounding final-period management and maintenance mechanism in the rural land consolidation project, reasonable implementation farmland management in larger scale, readjustment of agricultural structures, and so forth.
