Establishment and Application of Agriculture Landscape Pattern Spatial Optimization Model Based on GIS-MATLAB-CA

WANG Xue-ge et al(China Northeast Municipal Engineering Design and Research Institute,Changchun,Jilin 130021)  
The reasonable degree of the landscape pattern spatial distribution directly influences the sustainable use of regional land resource.Based on the unreasonable distribution of agricultural ecological landscape pattern and the increasing deterioration of ecological environment,the CA model's principle is used to establish the optimized rules,such as the landscape suitability rule,the landscape prior rule and restraint condition,and the standardization of the special data is realized by the competence of GIS spatial data handling and data spatial analysis,it is relied on the MATLAB platform to establish the landscape pattern spatial optimization model,that is LPSO model.The spatial pattern optimization of agriculture landscape has been realized and it makes the western Jilin agricultural landscape spatial distribution tend to reasonable and establish good foundation to realize regional agricultural sustainable development.
