长白山自然保护区风灾区植被恢复立地分类

长白山保护区风灾区的面积占保护区面积的5.8％,目前的恢复现状为：已恢复区大约占10％,半恢复区占7.9％,未恢复区占81.4％.本文以长白山自然保护区管理局横山、维东、池西、峰岭四个自然保护管理站的数据为基础,根据长白山区植被、土壤等的变化特征,确定植被恢复立地类型划分的指标体系和立地分类系统.结果表明,长白山自然保护区风灾区共有39种立地类型,其中,台地草地中层壤质山地棕色针叶林土,阴陡坡草地中层壤质山地棕色针叶林土和阴缓坡草地中层壤质山地棕色针叶林土三种类型所占的比例最大,分别为38.56％、19.53％、10.57％,面积分别为4390.35 hm^2、2223.78 hm^2、1203.99 hm^2.

The Classification of the Vegetation Restoration Site at Wind Disastrous Area in Changbai Mountain Nature Reserve

Wind Disastrous Area in Changbai Mountain Nature Reserve accounts for 5.8% of the whole protected area. The current vegetation restoration status to restore zone accounts for about 10%, semi - restored area 7.9% and non - recovery area 81.4%. Based on the four natural protection station data in Hengshan, WeiDong, ChiXi, FengLing of Changbai Mountain Nature Reserve Administration Bureau and according to the characteristics of vegetation, soil, site type, this thesis defines classification index system and site classification system. The results show that the site conditions of wind disastrous area in Changbai Mountain National Nature Reserve were 39 site types among which the plateau grassland middle loamy mountain brown coniferous forest soil, the negative slope grassland middle loamy mountain brown coniferous forest soil and the gentle slope grassland middle loamy mountain brown coniferous forest soil take the largest proportion, respectively 38.56% , 19.53% , 10.57% , and the areas are respectively 4390.35 hm^2, 2223.78 hm^2, 1203.99 hm^2.
