基于层次模糊物元模型的承接产业用地空间适宜评价

    Undertaking industrial land spatial suitability evaluation based on hierarchical fuzzy matter element model

    • 摘要: 如何立足产业转移、生态环境及用地开发战略高度,科学甄别承接产业类型及其用地空间布局,对于中西部地区尤其重要。以承接产业典型代表池州市域为研究对象,基于区位商和比较劳动生产率双重视角,构建产业转移判识模型,判识区域承接产业类型;从自然生态、基础设施、开发程度、开发效益4个准则层,构建产业用地空间适宜评价指标体系及其经典域、节域,综合运用层次分析法及模糊物元分析法,借助Matlab7.0、ArcGIS、Excel等数理软件,评价不同产业类型用地适宜程度,科学指导产业用地空间布局,促进区域土地资源开发与产业协调发展。研究表明:池州市产业区位商最大值、最小值分别为10.5421、0.0315,产业集聚度相对较高,而比较劳动生产率整体偏低,大于1仅有5个行业类型;结合矿产资源、生态资源、旅游资源等三大核心资源,判识未来承接及培育发展矿物采选业、纺织服装业、设备制造业、木材家具业及食品加工业5类产业;市域各类产业用地适宜普遍较低,且区域差异很大,较高集中分布市辖区和涓桥镇、乌沙镇、东流镇、香隅镇等沿江城镇带,以及围绕青阳县城周边的蓉城镇、陵阳镇、新河镇等集中连片区,而其他区域均较低;承接产业及工业发展空间走廊仅限于市辖区及沿江城镇带,其他区域以自然生态环境为主,不适合大规模国土空间开发,只能适当发展旅游、生态农业等绿色环保产业。

       

      Abstract: Abstract: It is of vital importance for the central and western regions to distinguish the undertaken industrial types as well as land space layout on the basis of transferring industry, ecological environment and land development strategy. In this paper, Chizhou City, the typical representative of undertaking industrial types, from the perspectives of location quotient and comparative labor productivity, constructs industrial transfer identification model and identifies regional undertaken industrial type. From four criterion layers of natural environment, infrastructure, development degree and development benefit, construct the identification model and the evaluation index system and its city domain and the classical domain; using analytic hierarchy process (AHP) and fuzzy matter element analysis method and mathematical software such as Matlab7.0, Arcgis and Excel, identify the regional industrial types undertaken and evaluate the industrial land development suitability. Research shows that Chizhou City industry location quotient varies from the maximum value of 10.5421 to the minimum value of 0.0315, which demonstrates that the degree of industrial agglomeration is relatively high while the comparative labor productivity is low overall, only 5 types of industry more than 1. Industry location quotient and comparative labor productivity are low, which shows that industrial development difference is small and without obvious hierarchical gradient. According to industry transfer identification model, the Chizhou industry is classified into 4 types, of which the numbers of competitive advantage industry and weak industry respectively reach 12 and 15, and stay out industry and undertaken industry account for only 5 and 2. Based on the advantages of the three core resources, i.e. mineral resource, ecological resource and tourism resource, five categories of industry including mineral mining industry, textile and garment industry, equipment manufacturing industry, wood furniture industry and food processing industry will be identified to be undertaken and fostered in the future. Land development suitability in the city is generally low, and the regional difference is obvious. The areas with higher land development suitability is concentrated around the city areas and around the towns along the river belt like Juanqiao, Wusha, Dongliu, Xiangyu, and is also gathered around Rongcheng Town, Lingyang Town and Xinhe Town surrounding Qingyang County. On the contrary, other types of industrial land have rather low development suitability degree. As a result, the undertaken industry and the space corridor of industrial development is only limited to the city areas and town zones along the river; to other regions, it is a good choice to develop green environmental tourism industry and ecological agriculture relying on the natural ecological environment, which is not suitable for large-scale land and space development. It has completed the evaluation of the five categories industrial land, overcame the subjective sideness in the multi-angle and multi-factor assessment, and followed a certain ambiguity and extension of the result itself. Scientific evaluation of industrial land suitability, clear developing direction of future industrial development type and expansion of land space in Chizhou, with rational industrial layout mode to drive the optimal allocation of regional land resources, are the effective ways to realize industrial projects guarantee. This idea and method in this paper can provide a reference for similar regions to evaluate the undertaken industry's land spatial suitability. In addition, the research results will also scientifically guide the industrial land space layout and further promote the regional land resource development and industrial coordination development.
