为完善长白山地区保护区体系、减少生物多样性破坏、保护阔叶红松林,对长白山国家自然保护区周边6个林业局、64个林场进行实地调查和数据分析;基于保护生物多样性的地理学方法(GAP),选择41种植物作为重点保护物种,以采伐区、农田、居民点、公路数等因子作为干扰因素,并利用GIS空间分析研究了长白山地区指示植物数量和干扰强度的分布.结果表明:不同林场指示物种分布不均匀,以泉阳县胜利、冷沟子林场为中心形成西北坡和南坡2个保护植物富集分布区域,宝马、衡山、冷沟子和黑河林场有单个重要物种分布;各林场干扰强度不同,露水河林业局和白河林业局北部整体受干扰程度较大.通过各项指标综合分析,确定出长白山北坡的泉阳-露水河南部-白河北部和长白山南坡的长白县东部2个生态保护关键区带.
In order to improve the system of protected areas in Changbai Mountain, reduce the damage of biodiversity and protect the broad-leaved Korean pine forests, field surveys and data analysis were conducted on 6 forestry bureaus and 64 forest farms around the Changbai Mountain National Nature Reserve. Based on the geography of biodiversity conservation (GAP), 41 species of plants were selected as key protected species, and the factors of cutting area, farmland, residential area and number of roads were used as interference factors, and spatial distribution of indicated plants and disturbance intensity in Changbai Mountain was studied by using GIS spatial analysis.Results The results showed that there were two distributions of protected plants on the northwestern slope and the southern slope centered on Shengli County and Lenggouzi Forest Farm in Quanyang County. There was a single distribution of important species in BMW, Hengshan, Lenggouzi and Heihe Forest Farm ; The intensity of disturbance in each forest farm was different, and the whole of the north of Lu Shuihe Forestry Bureau and Baihe Forestry Bureau was interfered by a large extent.A comprehensive analysis of various indexes determined that Quyang-Lushui River in the northern slope of Changbai Mountain- northern Baihe River and southern slope of Changbai Mountain Two key ecological protection zones in eastern Changbai County.
