【摘要】 为了保护黑龙江省大兴安岭天然林区的森林资源,促进天然林的可持续经营,以GIS为手段,利用森林经理调查和连续清查固定样地数据材料,在分析土地资源结构、生态环境及林种结构现状后,对黑龙江省大兴安岭天然林区的土地资源配置和林种结构进行了优化调整。结果表明:目前黑龙江省大兴安岭天然林区土地资源配置及林种结构极不合理,经过土地资源优化配置和林种结构调整后,用于生态公益林的土地资源增加,生态公益林面积比例超过70%。更多还原

【Abstract】 The present state of land resources structure, ecological environment and forest-type structure was analysed in order to protect forest resources and promote the sustainable development of natural forests in Daxing’anling forest region of Heilongjiang Province. The land resources disposition and forest-type structure were optimized and regulated using GIS techniques according to the data collected from fixed sample plots. Result showed that at present, the land resource disposition and forest-type structure of Daxing’anling are unreasonable. Land resources used in public beneficial forests will increase to more than seventy percent after the optimization of land resources and the structure regulation of forest-type.更多还原
