Abstract:

This paper, based on a brief introduction to Beijing’s development, sets up an index system to evaluate the land resources load capacity from population, construction scale, economy and ecology, applies mean variance analysis to evaluate Beijing’s land resources load capacity, and shows that, during 2004 to 2008, population load which is of high capacity and ecological load rose continuously; construction scale load fell with a low capacity; and economic load rose at a higher capacity. In general, Beijing’s land resources comprehensive load capacity is always rising until 2008. This paper presents approaches to Beijing’s land resources load capacity.

Key words: Beijing, land resources, load capacity, mean variance analysis
