Abstract
Abstract: Consolidation potential evaluation of industrial lands is important foundation for compilation and formulation of industrial land planning and selection of consolidation projects. It is also important for accelerating intensive and economical utilization of land resources and promoting sustainable development of industrial land. The consolidation potential of industrial lands is an comprehensive assembly of improving capabilities of various elements in industrial land utilization. It is defined as the increase degree in the respects of land productivity, production stability, economic feasibility, resources and environment protectability and social acceptability. An evaluation index system was constructed based on the consolidation potential connotation of industrial land by the theoretical analysis, experiences for reference and expert consultation. The evaluation indices comprehensively reflect the potential of industrial land in land use intensity, land effective use, land use structure, land comprehensive quality, land investment, land economic output, environmental quality, infrastructure improvement and geographical conditions. The indices were quantified by the appropriate method based on defining index connotation, and a fuzzy evaluation model was constructed for consolidation potential evaluation of industrial lands. Meanwhile, land parcels were appropriate to be used as evaluation unit in the consolidation potential evaluation for industrial land according to the consolidation practices of industrial land in China. During the evaluation process, the index standard values were determined based on 4 standards, including objective standard, social norm standard, design standard for urban land consolidation projects, and field survey and expertise. The objective standard and social norm standard refer to the maximum or minimum values under ideal conditions of evaluation system, and land use targets determined in the general planning of land use, regional development planning and city planning, respectively. The design standard for urban land consolidation project, and field survey and expertise refer to planning design value in urban land consolidation project, and standard according to typical parcel survey or expertise, respectively. Furthermore, the consolidation potentials of industrial lands were evaluated by GIS according to statistic data and field investigation data in Xingtai city. The potentials were divided into 3 levels, which were the first grade, the second grade and the third grade. The first grade zone covered the land parcels of number 1, 19, 20, 4, and 22. The second grade zone covered the land parcels of number 14, 10, 16 and 18. The third grade zone covered the land parcels of number 2, 3, 5, 6, 7, 8, 9, 11, 12, 13, 15, 17, 21, 23, 24, and 25. The evaluation results basically coincided with land use practical status of city industrial lands in Xingtai city, which demonstrated the difference among consolidation potentials of city industrial lands. The results indicated that this method was scientific, reasonable and practicable. The consolidation potential evaluation results for industrial land can provide foundation for compilation of general planning for land use and city planning. According to the evaluation results and comparison of land demand and potential-exploiting capability, the reasonable scale and scope of urban newly-added construction lands can be deduced, which supply policy support for annual implement plans of revitalizing land stock.
