With the acceleration of urbanization, the mass rail transit (MRT) is developing rapidly in China. However, some unsustainable problems are brought to many metropolitan governments, such as the expensive costs of MRT construction and operation, the incompatibility between MRT and its surrounding land use, the difficulty of MRT sharing the benefits brought by itself, etc. Therefore, for the sustainability of MRT, this research presents a transit oriented development (TOD) planning model of China. The paper put forward the objective functions and constraints of China TOD (CTOD) model and designed the algorithm of this multiobjective optimal problem. The problem is divided into two phases and parallel genetic algorithm is adopted. By these methods, the Pareto optimization solution set is searched so that it can offer some alternative land-use schemes. Taking the example of Dan Zhutou station of Shenzhen metro third line constructing, the land-use schemes in walking available scope of MRT station are designed considering MRT sustainability. The optimization results are alternative schemes of land-use type and land-use density in planned region, so that the land use can ensure the sustainable development of MRT. © 2010 ASCE.

Based on the advantages of single model in the field of land use simulation, This research construct a Markov-logistic-CA integrated model to reflect the land use change precisely considering both sides of macroscopic and microscopic factors. The conventional CA model is extended from two aspects including iteration times and conversion rules by Markov and Logistic respectivly. Finally the integrated model software is developed by VC.NET language and tested in the shenzhen city. The experimental result shows that Markov-logistic-CA model can better simulate and predict the situation of land use change rationally, and the result reached the expectant aim from the model accuracy test. It is conclusion that the Markov-logistic-CA model is a good tool to make decision for local government and have powerful computation function in complicated geographical system.

Monitoring land use status timely is the basis of rational management of land resource, and the important gist for planning agriculture or even the whole national economy. Possessing the advantages of macroscopic information, real time, periodicity and integrity, remote sensing provide the possibility for monitoring land use quickly, objectively and precisely. This research uses CART algorithm to draw knowledge automatically, and extracts classification image of the trial zone to analyze land use change in Xiangxi river watershed. It was concluded that Land use was unreasonable utilized at Xiangxi River basin in recently years, vegetation and the maintenance of water and soil were destroyed in a certain extent.
