Study on Synthesis Evaluation of Intensive Land Use and Growth Pattern Transformation of Towns

Abstract

It is very important that the scientific and reasonable evaluation on the intensive utilization of urban land and transformation of growth modes. It can enhance the levels of consolidation and management for urban land, maximize the intensive use efficiency of the land, and ensure sustainable development. In order to construct the comprehensive evaluation index system of the intensive utilization of urban land and transformation of growth modes. First, meet the the principles of scientificity, comparability and measurability, moderation, level, fairness and the goal-orientation. Second, consider the economic, social and ecological benefits from intensive utilization of land. Third, must be from the perspective of transforming the growth mode. Determine the weight coefficient of the evaluation indexes through weight determining method. The method is a combination of the AHP model supported by entropy technology and quantitative transformation of qualitative indexes supported by democratic decision-making of experts group. Then, apply fuzzy membership function method to conduct quantizing process for evaluated indexes. On this basis, build multi-target multi-level fuzzy comprehensive measuring model what is based on index system, use this model to calculate the value of comprehensive evaluation index. Take the new Zone of Northern Haidian District in Beijing as an example, and conduct a comprehensive evaluation research. The evaluation results indicate that the current intensive utilization level of urban land in Northern New Zone is low, which mainly reflected in the indexes of the water and soil resource utilization and ecological environment are not high. Therefore, further change of the growth mode should be made in the future so as to improve the intensive utilization level of land.
