摘　　要：根据矿业城市土地利用特点和三角模型性质,对阜新市城市土地可持续利用状态与趋势进行分析评价。结合非资源环境合理性、经济可行性以及非社会可接受性3个指数,选取反映阜新市自然、经济和社会等方面的19项评价指标,构建评价指标体系,运用层次分析法计算权重,然后采用加权平均法求得3个综合指数值,最后利用三角模型对阜新市市区土地可持续利用状态与趋势进行分析。结果表明:2001—2009年阜新市市区土地可持续利用状态由相对不可持续上升为相对一般可持续,土地可持续利用趋势由相对弱可持续转变为相对很强可持续;生态表现由最初的"差"转变为之后的"优"。三角模型在城市土地可持续利用状态与趋势评价方面具有可行性;阜新市需在以后的发展中重点解决产业结构调整、环境保护以及人口数量控制等问题。According to the characteristics of mining oriented urban land use and the nature of triangle model, the status and trends of urban land sustainable use of Fuxin was analyzed and evaluated. 19 evaluation indices reflecting the natural, economic and social elected to were selected build evaluation index system by combi- ning with the rationality of non-resource enviromnent, economic feasibility and non-social acceptability, and the analytic hierarchy process was used to calculate weight, three composite index values were obtained by the weighted average method. Finally, triangle model was used to analyze the status and trends of urban land sustainable use of Fuxin. The results showed that status of land sustainable use shifted from relatively non- sustainability to relatively common sustainability, the trends shifted from relatively weak sustainability to very strong sustainability, and ecological performance changed from weak to good condition from 2001 to 2009, in urban area of Fuxin. Itls feasible to apply the triangle model in evaluation of urban land sustainable use Fuxin need to focus on resolving the adjustment of industrial structure, environmental protection and population control in terms of the development in the future.
