Optimizing Land Use Patterns Based on Environmental Capacity: A Case Study of Dongying City

Abstract:

This paper evaluated the environmental burden and capacity of Dongying City by emergy and ecological footprint to provide basis for optimizing land development. The result shows that from 2000 to 2010, the land area needed to support human society expanded rapidly from 310000 ha to 735000 ha, while the environmental capacity increased from 1144900 ha to 1226100 ha, which would be caught up by environmental burden in near future according to the current trend. Pollutants assimilation is the main environmental burden and local nonrenewable resources accounting for more than 65.0 percent of the total human emergy consumption. Cultivated land and construction land are the major sources of environmental capacity. Hence the farmland and virgin land should be developed for multifunction and construction land used in a low carbon and intensivism way to promote environmental sustainability.
