    摘要:

    [目的] 对甘肃省庆阳市2012-2013年实施完成的15个土地整治项目进行综合效益评价,以期为庆阳市土地整治项目的实施与管理提供参考。[方法] 采用投影寻踪方法(PP)构建评价指标体系,借助实数编码加速遗传算法的投影寻踪分类模型(RAGA-PPC模型),从社会、经济、生态3个方面选取12个评价指标对项目实施的综合效益进行评价。[结果] 15个土地整治项目中宁县和正宁县的两个项目的综合效益为优,西峰区项目为良,合水县等的11个项目为中,华池县城壕乡项目最差。[结论] 研究区土地整治项目实施效益整体较好,但是还需要在制定和优化土地整治工程建设内容和管理时更加合理、平衡。

    Abstract:

    [Objective] The comprehensive benefits from land reclamation in Qingyang City of Gansu Province were evaluated to promote the implementation of land reclamation and to improve land management. [Method] A evaluation system was established by the projection-pursuit classification model of real coding accelerating genetic algorithm(RAGA-PPC), in which twelve evaluation indices, including the aspects of social, economic and ecological, was used to evaluate the comprehensive benefits from 15 projects of land remediation in Qingyang City from 2012 to 2013. [Results] In 15 land reclamation projects, projects of Ningxian County project and Zhengning County project were assessed having the best comprehensive benefits, Xifeng District having good benefits, Heshui County and other 10 projects having intermediate benefits, the lowest was Chenshao Township of Huachi County project. [Conclusion] The overall benefits from land renovation project were thought better, but the construction entries of land renovation project and the management need to be conducted more reasonably and jointly.
