Research Of Land-Use Structure Optimization Based On The Flexible Planning In Qianjiang City

In the phase of economic booming, more and more uncertain factors there are in land utilization. For this reason, it becomes increasingly difficult for land-use plan to forecast and control the future, which triggers the flexible land-use planning. The main content and elementary method of land-use planning is land-use structure optimization, which is regarded as a starting point in this study. Taking QianJiang city in Hubei Province as a case study, this thesis optimizes land-use structure through the concept of flexible planning and the model of grey multi-goal and dynamic programming(GMDP). The optimization scheme we acquired provides scientific reference for the city's new round of general land-use planning revision.Firstly, based on the relative research home and broad, this thesis summarizes on the theory of flexible land-use planning and gives a qualitative description of flexible land-use structure.Secondly, by analyzing the merits and drawbacks of traditional optimization methods, this thesis introduces a grey multi-goal and dynamic programming method, and describes the modeling process.Thirdly, this thesis analyzes the state of land-use conditions in QianJiang city from three aspects: the natural foundation, social-economic environment and the problems in existence of land utilization. Then, it defines the strategies and the main objectives in new round of general land-use planning.At last, this thesis aims at the study area to simulate the whole optimizing process. The design is driven as follows:(1)divides the planning period into three stages;(2)forecasts the flexible demands of land-use to get the parameters of the model;(3)puts 12 variables, 10 terms of restraining, and 3 goal functions to set up the model and solves it by applying WINQSB;(4)constructs three typical schemes, then determines the optimal one by a combination of qualitative and quantitative analysis.The study proves that it's feasible to optimize land-use structure by the GMDP with support of computer, and it shows a variety of results in the future land utilization, that reflects the flexibility of the planning...
