中文摘要：根据东北地区生物多样性特征,利用系统保护规划方法和国际上常用的保护规划软件C-plan,计算了规划单元的不可替代性值,确定了区域生物多样性热点地区,并根据保护区分布现状进行了生物多样性保护空缺分析。结果显示,东北地区不可替代性较高的热点地区有4个,分别是:(1)长白山西北部林区,(2)大兴安岭北段山地区,(3)大兴安岭南部森林与草原过渡区,(4)松嫩平原中部湿地区.在优先、一般、非优先3个等级中,需要优先保护地区的总面积是19.49×104km2,约占区域总面积的20.91%。同时,根据已建保护区分布情况研究发现,区域内存在3个明显的保护空缺,即长白山西北部林区、大兴安岭北段山地区和大兴安岭南段森林草原过渡区。建议新建和扩建保护区,同时建立生态廊道把相应的保护区关联起来,以实现区域内生物多样性保护目标。

外文摘要：Based on the researches on biodiversity characteristics in Northeast China,The value of irreplaceability for the conservation planning units are calculated by using systematic conservation planning and software C-plan.Four hotspot areas are identified,including northwestern of Changbai Mountain,northern Daxinganling Mountain,the transitional zone between western grassland and Daxinganling forest mountain area,and the wetlands around the center of Songnen plain.The most priority area for conservation is 194,900 km^2,20.91% of the whole research area.In the meantime,a gap analysis for biodiversity conservation has been conducted in this region based on the results of hotspots′ assessment,The results show that there are three evident gaps for protection based on an analysis of currently existing national nature reserve,including Changbai Mountain area,northern of Daxinganling Mountain area,the transitional area between western grassland and Daxinganling forest mountain area.Suggestions for establishing new PAs and eco-corridors have been put forward in this paper.
