Abstract:

In order to evaluate the intensive and economical utilization of land in Chengdu ‘1+7’ economic zone, and to promote further intensive and economical land-use in these areas, the author had constructed an overall evaluation index system of urban land intensive and economical utilization from 4 aspects: land investment intensity, land use intensity, land output effectiveness, and land sustainable utility. The methods of AHP and Delphi technique were adopted to determine the weight of index, while the Matlab software was applied to conduct fuzzy comprehensive evaluation. The results showed that the land investment intensity, the second and tertiary industry development level directly influenced the urban land intensive and economical utilization. The efficiency of intensive land-use was at a low level in the districts mentioned: Chengdu was at a moderate intensity, Deyang at a preliminary intensity, Mianyang and Ziyang at a low-grade extension, and Leshan, Suining, Meishan and Ya’an at a moderate extension. Confronted with the severe status quo, the author objectively put forward suggestions, including optimizing and adjusting the industry structure, focusing on the development of the buit-up area and the exploration of the potential so as to increase the per land income and choose the mode of intensive development and so on.
