| 摘 要： | 进行土地集约利用评价比较的前提是不同区域或行业间应具有可比性,本研究首先阐释了土地集约利用评价的可比性问题,然后设定了产业差异修正系数,在对江苏省各工业行业土地利用指标进行产业差异修正的基础上,评价了各工业行业及各区域的土地集约利用水平。研究结果表明:①土地利用指标经过修正后,行业间差异和区域间差异明显变小,个别指标出现了在不同区域间的优劣转变;②苏南、苏中、苏北工业行业土地集约度差异较大,从全省工业行业情况来看,土地集约利用总体水平偏低,黑色金属冶炼、造纸、石油加工、机械制造类、通信电子类行业土地集约度相对较高;③产业差异修正前后,工业行业土地集约利用评价结果存在一定差异,苏南工业行业平均土地集约度低于苏中。

| Abstract: | The aims of this paper are to illustrate the meaning and method of comparing evaluation results of land use intensity, and improve levels of intensive land use. We described the comparability of intensive land use, and note that when comparing evaluation results equal consideration and the correct land use status for different industries are needed. In order to modify differences caused by land scale, production processes and technical processes, we set correction factors for land use for different industrial sectors according to the construction land norm for Jiangsu province. Finally, we established an evaluation index system of land use, and evaluated the level of intensive land use between different industrial sectors and regions. The results indicate that differences in inter-regional and inter-industry land use are smaller, and some indicators change the pros and cons in different regions. Land use intensity is different among the three regions in Jiangsu province, and different industries exhibit different characteristics on land use. Leading industries in Sunan such as the communications-electronics manufacturing and machinery manufacturing did not show high land use intensity; some high-tech industries show higher land use intensity in Suzhong and Subei. At the provincial level, the level of industrial intensive land use is lower, and in some industries is higher, such as for ferrous metal smelting and rolling, papermaking, petroleum processing, machinery manufacturing and communications-electronics manufacturing. The results of the evaluation indicate differences before and after modification, and some habitual ideas about land use are overthrown. For example, land use intensity in Sunan is significantly higher than Suzhong and Subei, and land use intensity in Suzhong is highest. |
