不同发展阶段的煤炭型城市土地集约利用研究

以老年型、中年型、幼年型这三个不同发展阶段的煤炭型城市为研究对象, 一方面紧扣建设用地单位面积上的投入与产出; 另一方面更多地考虑与煤炭生产状况及其有关的环境效益, 在此基础上构建集约利用评价指标体系, 并结合层次分析法, 对不同发展阶段的煤炭型城市土地集约利用进行了评价, 将评价结果从煤炭型城市土地投入、土地产出和土地利用结构对集约利用影响的角度进行了分析, 得到不同发展阶段煤炭型城市土地集约利用影响因子的差异, 表明山西省样本煤炭型城市的土地集约利用度要高于黑龙江省,老年型煤炭城市土地集约利用的潜力很大。并且提出了煤炭型城市土地集约利用程度的挖潜方式, 为煤炭型城市的土地集约利用与城市转型提供了参考。

Land Intensive Use of Coal Cities at Different Development Stages

Although much research work has been devoted to the urban land intensive use, researches on the land intensive use in coal cities, especially at different development stages, remain insufficient. With coal cities at different development stages as the study objects, this paper has divided these cities into aged, middle-aged and infant types. For example, Hegang and Datong are of the first type, Shuangyashan and Yangquan are of the second type, and Qitaihe and Shuozhou are of the third type. Assessment indexes were chosen from the peculiarities of coal cities, which included economic investment, human investment, resources investment, economic output, social output, environment output and land use structure. AHP method was used to get the weights of different factors and to calculate the degree of land intensive use in different coal cities. The results from the influential factors were analyzed, and difference in land intensive use was obtained. Some suggestions are put forward concerning the improvement of the degree of land intensive use, which are helpful to the land intensive use in coal cities and the transformation of city functions.
