1、木兰林管局森林资源空间配置研究 木兰林管局森林资源空间配置研究 study on mulan forestry adminstration bureaus spatial configuration of forest resources research【中文摘要】 森林资源合理空间配置,是森林可持续经营的重要基础,是实现林业分类经营的前提。针对森林经营过程中,所面临的森林经营目标不明确、森林经营类型缺失等问题,在明确林业发展定位的基础上,按照森林分类经营要求,通过森林资源空间配置,最终解决“哪该有”、“有什么”林种,以及“确定林种后如何经营”等森林经营中必须解决的重大问题,对于最终建立以森

2、林经营方案为核心的森林资源管理体系,促进森林可持续经营,具有重要意义。研究工作,以河北省木兰林管局为研究对象,围绕森林资源空间配置与森林资源分类管理理论与技术问题,运用2005年最新森林资源二类调查资料,以地理信息系统为研究平台,同时借助利用sql选择模块分析方法,研究主要结论如下:(1)选取林地主要控制因素指标构建了包括13个指标的林地适宜性评价指标体系,以小班为评价的基础单位,对木兰林管局的林地资源进行了林地林种适宜性评价,并确定了划分等级界限值以及其计算方法。(2)从木兰林管局区位条件出发,按照林地适宜性评价体系,将全局划分为水源涵养林3 538.2 hm2、水土保持林5 307.7 h
