摘要:
[目的]测度土地利用绩效水平及诊断其障碍因子,为贵阳市生态文明建设和土地资源管理提供重要参考。[方法]从土地利用经济绩效、社会绩效、生态绩效和公平绩效4个方面构建贵阳市土地利用绩效评价指标体系,运用改进的多属性群体决策理想点法TOPSIS (technique for order preference by similarity to an ideal solution)模型和障碍度模型,对贵阳市2006—2015年土地利用情况进行绩效评价及障碍因子进行诊断。[结果]①贵阳市土地利用绩效在波动中呈稳步上升态势,绩效水平从较差上升至优质;②四大准则层的绩效水平整体提升,但增长方式存在差异,其中社会绩效与生态绩效增速最快,经济绩效与公平绩效相对较晚进入中级水平;③经济绩效和社会绩效是影响土地利用绩效的两大障碍因素;④从指标层因子的障碍度来看,未来影响贵阳市土地利用绩效的主要障碍因子是城市人均可支配收入、生态治理面积、地均就业人数、房价收入比和恩格尔系数。[结论]改进的TOPSIS模型与障碍度模型相结合能够客观、真实地反映贵阳市土地利用绩效变化状况及存在的绩效障碍问题。

Abstract:
[Objective] The land use performance and its diagnose obstacle factors were evaluated in order to provide references for ecological civilization construction and land resource management in Guiyang City.[Methods] The land use performance evaluation index system of Guiyang City was constructed from four aspects:land use economic performance, social performance, ecological performance and fair performance. The improved technique for order preference by similarity to an ideal solution(TOPSIS) model and obstacle degree model were used to evaluate the land use situation of Guiyang City from 2006 to 2015. Performance evaluation and obstacle factors were used for diagnosis.[Results] ① The land use performance of Guiyang City showed a steady upward trend in fluctuations, and the performance level improved from poor to high quality. ② The performance of the four criteria levels improved as a whole, but there were differences in growth patterns, among which, social performance and ecological performance have the fastest growth rate,while the economic performance and fair performance have entered the intermediate level relatively late. ③ Economic performance and social performance were two major factors affecting land use performance. ④ From the obstacles of the indicator factor, the main obstacles affecting the land use performance of Guiyang City in the future would be urban per capital disposable income, ecological management area, average employment, house price income ratio and Engels coefficient.[Conclusion] The improved TOPSIS model combined with the obstacle degree model can objectively and truly reflect the change of land use performance and the existing performance obstacles in Guiyang City.
