土地利用空间配置的空间化遗传优化模型与算法研究

Land use planning is the main means to optimize the development pattern of land and to promote rational and effective utilization of land resources. How to complete the rational allocation of regional land resources in temporal and spatial dimension and then to accomplish the optimization of land use quantitative structure and its spatial layout is the core of land use planning, which is currentlt the difficulty and the research hotspot of land science. Aimming at shortcomings in quantization, ramdomization and efficiency which are reflected when intelligent algorithms are utilized to solve problems from the field of optimization of land resources allocation, the study on the improvement of intelligent models and algorithms for spatial optimization is carried out and genetic algorithm is selected as an instance. Through studying the spatial representation of the optimization model based on GA, genetic operations combined domain knowledge and algorithm parallelization, the spatial optimization model of land resources, based on the direction of domain knowledge and spatial GA, is constucted. Wuhan is selected as the study area for model validation. To lay a theoretical and technical foundation for the intelligent optimization of regional land use structure and its spatial layout, theories and technical methods on genetic optimization, which are coupled with land use issues, are expected to be established.
