An assessment indicator system for regional land use efficiency was established in this paper from the aspects of society,economy,ecology and environment. The weight of each indicator was defined by an analytical hierarchy process (AHP) and the entropy method (EM). Then,a case study in Zhanjiang was carried out to analyze the regional land use efficiency from 1996 to 2004 and its development by using the method of multifactor composite evaluation and an analytical model of the de-gree of coordination. The results indicate that land use efficiency with respect to society and the economy improved,whereas the ecological and environmental efficiencies were found to decrease. The degree of coordination in Zhanjiang is still at the status of basic coordination. Finally,measures for enhancing the ecological and environmental establish-ment are suggested in order to improve the regulations of land use structure and patterns,establish ecological forests for the public good and green corridors and prevent the soil erosion.展开更多

The urban environment is a supporting systemto the sustainable development of city. Taking the urban area of Chongqing as an example, this paper establishes theindicator system for assessment of the coordination between urban environment and economy according to the resultfrom principal component analyses by software SPSS11.0. Meanwhile, the weight was assigned for each indicator basedon the load of the first proper principal components. Through computation of the coordinated development model set upaccording to the knowledge of statistics, the paper draws the conclusion that the situation of the coordination betweenenvironment and economy in Chongqing developed well from 1996 to 2004. Finally, countermeasures for the coordina-tion in the coming years are proposed.展开更多
