Abstract:

Effectiveness evaluation is the base and starting point for land-use general planning. Taking 31 provinces, autonomous regions and municipalities of China inland as samples, an index system including product effectiveness, quality status, structure status, utilizing level, utilizing intensity, and conditions of resources is set up for comprehensive evaluation of China’s land-use. Under the help of Matlab6.5 we used correspondence analysis to characterize the status of comprehensive effectiveness of land-use in China. The conclusions of the study are: 1) China’s land-use effectiveness is controlled under the first and the second main factors which express the effects of production effectiveness and utilizing intensity, and the factors of quality status and amount of resources have limited effects on China’s land-use effectiveness. 2) Investment increase in construction results in increase of the output from construction land and the decrease of the output from agricultural land, and eventually results in the loss of output of land-use. 3) 31 provinces, autonomous regions and municipalities are assorted into 7 types, and Shanghai, Beijing, Tianjin belong to a high-level type of which two main factors act harmoniously.
