| 摘 要： | 该文在分析防护林体系空间配置的研究现状及存在问题的基础上,提出了防护林体系空间配置调整的要素和步骤,研究了小流域尺度防护林体系空间配置调整的主要思路和技术路线,构建了调整分期内的防护林体系空间配置调整的0--1整数规划模型。该模型选择一组需要进入调整分期的小班,以最大限度地发挥了防护林体系的防护效益为目标,经营成本和改进现有的空间配置为约束,生成可供决策者参考的调整方案。该研究充实了防护林体系空间配置的关于现有状态调整的理论研究,同时对于防护林管理部门的生产实践具有实际指导意义。

| Abstract: | Based on the analyses of the research status and existing problems of spatial allocation for protection forest system,the authors studied the elements,steps,main ideas and technology line of its regulation,and established 0-1 integer programming regulation model in a regulation period.The model can provide the regulation scheme through choosing a group of subcompartments that need to be regulated,aiming at their protection efficiency maximization,constraining its operation costs and improving its existing s... |
