大都市郊区工业用地减量化适宜性评价方法与实证

工业用地减量化是节约集约用地管理制度下大都市用地转型的必然,也是地方实践在土地整治领域的创新尝试。论文建立大都市郊区工业用地减量化适宜性评价方法,以上海市浦东新区大团镇为例,客观评价其减量化的适宜等级。研究结果表明：1）工业用地减量化的5个影响因素中,污染与能耗因素值差异最大,布局合理性因素值差异最小,主体意愿性因素的空间分布差异最明显;2）218个工业地块划分成5个适宜度等级,随着适宜度提高,相应工业地块零星程度加剧,地块平均规模由适宜度一级的9 507 m²逐渐下降至五级的3 300 m²;3）一级适宜占24.06%,二级适宜占21.51%,三级适宜占29.45%,四级适宜占12.63%,五级适宜占12.35%。适宜等级所占面积的分布接近于正态 分布特征。研究结论：论文所建立方法可作为大都市郊区工业用地退出的评估工具,有助于提高工业用地减量化的统筹协调性。

Suitability Assessment of Reducing Industrial Land in Shanghai Metropolitan Region

Due to the extensive expansion of urbanization since 1990s in Shanghai, there are serious problem in industrial land use, such as low efficient, high pollution risk and decentralized spatial layout. As the first city in China committing to limit the total amount of land allocated for construction, Shanghai plays a critical role in informing reducing industrial land. Reducing industrial land emphasized that the land use should be returned from industrial land to ecological land or agricultural land. Taking Datuan Town in Pudong of Shanghai as an example, this study provides a suitability evaluation method for reducing industrial land in metropolitan suburbs. Geographical Information System tools are used to analyze the 218 industrial land parcels in the whole town. Results indicate that: 1) Among the five factors influencing the reduction suitability of the 218 industrial land parcels, the values of pollution and energy consumption showed the biggest difference, while the value of rationality of layout had the smallest difference, and willingness of land right owners had the biggest difference in spatial distribution. 2) When the suitability grade of reduction of industrial land increases, the industrial land parcels become more sporadic. The average area of parcels varieties from 9 507 m² in suitability grade 1 to 3 300 m² in suitability grade 5. 3) According to the evaluation index value and its spatial distribution, five suitable grades are classified. The total area of parcels in the first grade is 24.06%, in the second grade is 21.51%, in the third grade is 29.45%, in the fourth grade is 12.63% and in the fifth grade is 12.35%. The distribution of the area in different grades is close to the normal distribution. 4) The industrial lands which are suitable for reducing before 2020 are mainly located in Zhaoqiao Village, Shaocun Village, Tuanxin Village, Jinyuan Village and Jinshi Village. The industrial lands which are not suitable for reducing before 2020 are mainly distributed in Tuanxi Village, Guoyuan Village, Longshu Village, Zhennan Village and Chezhan village. The method proposed in this paper not only can be used to evaluate the suitability of reducing industrial land in one city, but also can be used to compare the suitability reducing industrial land among similar cities so as to improve the coordination of the industrial reduction on a larger scale.
