The results indicated:（1）the combination of the Markov and spatial logistic models can improve the predictability of each model individually. In macroscopic scale, the total land use amount can be predicted via Markov chain; in microscopic scale, the multi-class multinomial logistic model can be used to implement the combined calculations of categorical variable and continuous variable, qualitative variable and quantitative variable to improve the precision of spatial regression. Meanwhile, the transition probability of each land use unit will be confirmed and the prediction of land use spatial distribution will also be completed.（2）the application system developed in accordance with the integrated model can effectively simulate and predict the land use evolution in Shenzhen City, and the prediction precision of verification system will suffice for recent land use monitoring and the making of annual land supply planning.

Based on connotation of intensive land use and the evaluation principle of intensive deployment of city land,this paper establishes a set of scientific and practical index system in evaluating the intensive utilization of city land,and conducts a demonstration analysis in 13 cities of Jiangsu Province by the way of multifactor comprehensive evaluation,rank correlation coefficient and cluster analysis.During the last ten years from 1997 to 2006,the urban land use intensity had increased in all cites,but varied in amplitude and mode in different cities.Urban land use intensity was descending sharply from the southern and the middle to the northern part of Jiangsu Province,in which Nanjing was the tiptop and Suqian was the lowest .

The fact have been proved that we must solve these problems, allocate land reasonable and make intensive utilization of land resource in order to quicken up the citify process and improve the life quality of people. The process of urbanization should be the process of intensified utilization of lands. The phenomenons of extensive exploitation of land, irregular market and the lack of management have already obstructed the reusable source of land and the fast development of the citys economy. Therefore, it has become the urgent affairs to build up the indicator system of measuring the intensive use of urban land and look for a way to carry out.

Land use type is the outcome of duple influence of nature and human activity, which possessing scrambling, relative instability and complexity, and it can be discussed by fractal theory. Application of fractal theory in land use structure involve in the calculation of fractal dimension of land use type, research method and fractal description of change of land use structure, fractal model of region landscape and so on, but fractal mechanism of spatial diversity of land use type is rarely reported.

Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.
