A Stndy on Optimization of Land Use Structure Based on Quantitative Analysis of Ecological Footprint-A Case Study of Xuzhou City, Jiangsu Province
Ecological footprint method is an effective approach for quantitative evaluatation of the regional sustainable development. Dynamic changes of ecological footprint(EF) and ecological capacity(EC) were analyzed based on ecological footprint method and land use sustainability was assessed using EF
EC and other indicators of Xuzhou City
Jiangsu Province from 1999 to 2008. The results showed that the per capita ecological footprint of Xuzhou City increased from 1.13 hm2 in 1989 to 2.57 hm2 in 2008
and the per capita ecological capacity decreased from 0.58 hm2 in 1989 to 0.45 hm2 in 2008. The per capita ecological deficit increased from 0.55 hm2 in 1989 to 2.10 hm2 in 2008. Intensification of land-use is low in Xuzhou City. The author used a linear regression model to predict the population
and predicted the ecological footprint of 2010-2015 by gray prediction model. The multi-objective linear programming model was built to optimize the land use structure in Xuzhou City
which minimizes ecological deficit and maximizes economic benefits as the objective function
and sets up seven variables and nine constraints. The land use structure was optimized in Xuzhou City according to optimal scheme.
