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

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.
