基于CLUE-S模型的土地利用格局优化研究

The Study of Landscape Pattern Optimization Based on CLUE-S Model

利用CLUE-S模型,通过限建区的划定,土地利用需求预案的设定以及转化参数的设置,完成土地利用类型的空间分配,对研究区的土地利用格局进行了定量的优化。结果显示CLUE-S模型较好地实现了对研究区土地利用格局定量优化的策略,能够反映土地利用的需求预案,体现限制区域的划定,完成空间明确的土地利用类型位置分配,是实现土地利用格局优化的有效方法。另外,CLUE-S模型也对建设用地的增长起到指导作用,这种特性使其具备了应用于城市增长模拟研究的潜力。图2,表3,参19。

This paper completed the spatial allocation of all land use types,and optimized the land use pattern of the study region with CLUE-S model,accompanied by the setting of restricted construction area,land use demand scenarios and conversion characteristics. The results showed that CLUE-S model accomplished the quantitative optimization of landscape pattern,and reflect the land use demand scenarios and restricted construction area. It is capable of land use location allocation,and proved to be an effective method for landscape pattern optimization. In addition,CLUE-S model is able to guide construction land growth,which enables it to be used in urban growth simulation researches.
