Abstract:

General land use planning and urban master planning are the basis of urban land use and land development. Coordination of their relation is of great significance for urban land use planning, and the quantitative evaluation of the coordination degree is extremely important to the preparation and implementation of these two planning. To evaluate the coordination degree of general land use planning and urban master planning, a coordinating comprehensive evaluation system was built through analyzing the content and connotation of these two planning, and then 13 indices in terms of economy, society, resources and environment were selected. The increase rate of each index from the results of these two planning was calculated, and then the Synergisticity Model was applied to calculate coordination degree of each index. After determining the weight of each index by the Analytic Hierarchy Process (AHP) method, the coordinate degree of these two planning was calculated by synthesizing coordinate degree of each index and index weights. Geography Information System spatial overlay analysis was applied to determine spatial difference of the land use in these two planning. Taken Nanjing City as an example, the coordinating value and degree of these two planning were calculated by the model. The results showed as follows. The coordinating value of compilation achievements of these two planning in Nanjing city was 91.58, and the coordinate degree was medium. The coordinate degree of indices among economy, society, resources and environment were different. Indices in terms of economy and society had high coordinate degrees, while indices in terms of resources and environment had low degree. The inconsistency of these two planning was contributed to the difference of land use database in the base and planning period. In order to improve the coordinate degree of these two planning in Nanjing City，the database of the land use in base period and planning period should be consistent
