摘　　要：[目的]从经济、社会、生态3个维度对武汉市2005—2017年土地利用多功能性及其障碍度进行评价,以提高土地利用效率,促进区域土地合理利用,实现区域可持续发展。[方法]根据目标层—指标层—要素层框架构建评价指标体系,运用熵权TOPSIS法确定指标权重并计算障碍度。[结果]①研究期间武汉市土地利用综合功能呈现总体上升的态势,功能协调性呈Z型式下降,功能变化优势度呈波浪式下降,土地利用日益多样化。②经济、社会、生态功能有着不同程度的增长,其中经济功能、社会功能均经历了低级—中级—良好—优质的发展阶段,整体增长快速;生态功能经历了低级—中级—优质的发展阶段,虽小有波动,但总体大幅增长。③经济功能、社会功能障碍度有所下降,而生态功能的障碍度不断上升。其中,SO 2年均浓度、经济密度、人均GDP、卫生机构密度、人均水资源量等障碍因子影响较大。[结论]武汉市应当注重生态功能的提升,转变经济发展方式,推进产业升级,实施清洁生产,减少三废污染,同时注重水资源的保护,实现土地的可持续利用。[Objective]The multi-functionality of land use and its obstacles in Wuhan City during 2005—2017 was evaluated in terms of economy,society and ecology in order to improve the efficiency of land use and promote the rational regional land use and achieve regional sustainable development.[Methods]According to the target layer,index layer and element layer framework,an evaluation index system was constructed,and the entropy weight TOPSIS method was used to determine the index weight and calculate the obstacle degree.[Results]①During the study period,the comprehensive function of land use in Wuhan City showed an overall upward trend,the coordination of functions showed a Z-shaped decline,the dominance of functional changes showed a wavy decline,and land use became increasingly diversified.②The economic,social and ecological functions had different growth levels.Among them,the economic and social functions experienced low-intermediate-good-quality development stages,and the overall growth was rapid;the ecological functions experienced low-intermediate-quality development.At this stage,although there were small fluctuations,the overall growth was substantial.③The degree of economic and social dysfunction declined,while dysfunction of ecological functions continued to rise.[Conclusion]Wuhan City should pay attention to the improvement of ecological functions,transform the economic development mode,promote industrial upgrading,implement cleaner production,reduce the pollution of the three wastes,and pay attention to the protection of water resources and realize the sustainable use of land.
