| ［目的］城市近郊区土地不仅关系到城市建设，也影响着社会经济的发展，是我国土地资源的重要组成部分。对城郊土地的可持续利用进行评价，从而确定土地利用目前的状态以及存在的问题，为今后完善土地利用规划，最终实现土地的持续利用具有重要意义。［方法］从经济可行性、社会可接受性和资源环境协调性3个方面构建济南城郊地区土地可持续利用评价体系，采用熵值法和加权法计算综合评价分值，并利用障碍因素分析法对2009—2017年该地区土地的可持续利用状态和主要限制因素进行了分析。［结果］（1）济南市城郊土地可持续利用的综合评分呈上升趋势，分值由2009年的0199提高到2017年的0827，可持续性程度明显提高，由不可持续过渡到了可持续程度很高，但土地可持续利用的社会接受性与经济可行性和资源环境协调性并不平衡。（2）对济南城郊土地可持续性利用的障碍因素进行诊断，确定出主要障碍因子依次为人均耕地面积、地均固定资产、垃圾无害化处理率和污水处理率。［结论］济南城郊土地可持续利用程度虽然呈现上升趋势，但提升空间还很大，针对限制土地资源利用的障碍因素，今后应从增加资本和科技投入，提高垃圾的处理率和切实保护耕地入手，从而实现土地的可持续利用。 |

| Abstract: |
| The land in the suburbs of the city affects not only urban construction, but also development of social economy. It is an important part of China′s land resources. The evaluation of the sustainable use of suburban land to determine the current state of land use and existing problems is of great significance for improving land use planning in the future and ultimately realizing the sustainable use of land. Taking Jinan suburbs as an example, this research constructed the land use evaluation system from three aspects: economic feasibility, social acceptability and coordination of resources and environment. Moreover, it calculated the comprehensive evaluation scores by adopting the entropy method and weighting method. In addition, it analyzed the sustainable use status of land and major limiting factors in research area from 2009 to 2017 by utilizing the obstacle factor method. The comprehensive score of sustainable use of suburban land in Jinan city was on the rise, with the score increasing from 0.199 in 2009 to 0.827 in 2017. The degree of sustainability had improved significantly. The transition from unsustainable to sustainable was high, but the land was sustainable, but the social acceptance and economic feasibility of sustainable land use and the coordination of resources and environment were not balanced. The obstacles to the sustainable use of the suburbs of Jinan were diagnosed, and the main obstacle factors were determined by the per capita arable land area, the fixed assets of the land, the harmless treatment rate of garbage and the sewage treatment rate. Although the sustainable use of land in Jinan suburbs is on the rise, there is still a lot of room for improvement. In order to limit the barriers to the utilization of land resources, we should increase the capital and technology investment, improve the treatment rate of garbage and protect the cultivated land to realize sustainable use of the land. |
