以浙江省天目山国家级自然保护区少受干扰的毛竹林为研究对象,基于GIS空间分析功能,建立毛竹林空间结构优化调控模型.模型目标是空间结构,非空间结构作为主要约束条件,模型属非线性整数规划,采用Monte Carlo法求解.模型求解得到最优采伐方案,此方案对毛竹林空间结构进行优化调控,使林分空间结构目标函数值比伐前提高32.650 0％,最大限度地改善林分空间结构,又不破坏非空间结构,可作为制定采伐计划的依据.
Spatial Structure Optimizing Adjustment and Control Model of Phyllostachys edulis Stand
Spatial structures of current Phyllostachys edulis stands are usually irrational. Based on non-spatial structure requirements, how to adjust and control the spatial structures of Phyllostachys edulis stands to lead to rational state is a focus problem in practice. This study used a less disturbed Phyllostachys edulis stand in Tianmu Mountain National Nature Reserve of Zhejiang Province as a research object, a spatial structure optimizing adjustment and control model of Phyllostachys edulis stand was established based on GIS ( geographic information system) spatial analysis function. The objective of the model is spatial structure, non-spatial structures are its constraints. The model belongs to nonlinear integer programming, Monte Carlo algorithm was used to solve the model. An optimal cutting plan was obtained by solving the model. Based on the plan, through spatial structure optimizing adjustment and control of Phyllostachys edulis stand, the objective function value of stand spatial structure after cutting increases 32. 650 0% than that of before cutting. The stand spatial structure is improved at the furthest and non-spatial structures are not destroyed. Therefore,this plan can be used for making cutting plan.
