Land Use Planning In Urban Land Multi-objective Optimal Allocation Model And Its Algorithm

Land use planning is normative country land use, land use change in China in the structure is notreasonable, land use planning is important in China. The optimized allocation of land resourcesand land use planning of the same nature, all in order to achieve certain economic andenvironmental benefit target, make land use more reasonable, while it has not affected by variousplanning index constraints, only looking at one of a number of benefit maximization, under idealconditions, more solution towards quantitative advantages, these make it for land use planning asthe reference is a kind of important method. Based on the summarizing production of domesticand international relevant study, author try to design basic theoretical system,it can help thedepartment of managing and planning to find the better goal scheme of land use. In order tobetter service for land use planning.This article made a content: firstly carried out on the land suitability evaluation basic theoryresearch, construction land suitability evaluation system; then the development of spaceallocation optimization algorithm, constructs the city land resources optimal allocation model;finally specific case, taking Ji’nan city as an example to make land use database, and on this basisfor practical application.In this paper the application of method have two kinds: (1) the city land suitabilityevaluation.(2) Using multi-objective genetic algorithm to the original space, the land use typecross, variation, recombinant.Most of the results with the previous improvements were: Thispaper adopts three kinds of evaluation system can result in different locations suitable for whatpurpose; the previous single objective optimization, multi-objective optimization scheme into.According to the Ji’nan land resources spatial optimization results, and then with the Ji’nancity planning programmes were compared, the research methods and advantages anddisadvantages of objective and accurate evaluation, draw on the entire city of Ji’nan, land usesthe current situation and future areas in need of improvement.Using geographic information system to establish a can collect various data information andbe able to fast analysis and output of the system, improve, rich city planning design andconstruction means, improve the efficiency and management level of city planning andconstruction, is the contemporary China city planning and city management the inevitabledevelopment direction. Also the letter how specific applications to various research fields mainlymethod.
