摘　　要：为了更好地维持城市绿地系统的稳定,获取城市绿地率演变规律特征,提出城市绿地率空间分异格局及其演变规律模拟方法。预处理遥感数据,基于数据处理结果提取城市绿地率空间分异格局特征;通过城市绿地斑块之间的连通关系构建绿地连通图,采用邻近事件矩阵统计绿地连通空间的排列特征,获取城市绿地率演变规律。将得到的全部特征输入到Matlab仿真软件中展开仿真分析,经实验测试结果证明,所提方法可以获取满意的模拟结果,演变规律模拟效率与精度较高。In order to maintain the stability of urban greening system and obtain the characteristics of evolution law,this article puts forward a method of simulating the spatial heterogeneity pattern of urban greening rate and its evolution law.At first,the remote sensing data was preprocessed.On this basis,the characteristics of spatial heterogeneity pattern were extracted.And then,a connectivity map was constructed through the connectivity relationship between urban green space patches.Moreover,the adjacent event matrix was used to obtain the arrangement characteristics of connected space.Finally,the evolution law of urban greening rate was obtained.All the features were input into the MATLAB software for simulation analysis.Experimental test results show that the proposed method can obtain satisfactory simulation results.;And the simulation efficiency and accuracy of the evolution law are high.
