Abstract:
Based on the weights and membership values of evaluation indices, a measurement model of construction land intensive utility in Zijin County of Guangdong Province was established, and the basic principles of the greatest compatible class were adopted to classify the intensive utility levels of the construction land based on fuzzy recognition. Additionally, the intensive utility potential of construction land in Zijin County in 2005 was calculated by comparing the per capita construction land in towns, independent industrial and mining areas, and rural residential areas with the latest national land use standards for planning of town launched in 2007. The predicted value of the model was 0.421, suggesting that the construction land utility in Zijin County was still low- effective and extensive. Theoretically, the construction land area could be decreased by 555.69-2197.69 hm2, which meant there was a great potential in the intensive utility of construction land in the county.
