摘 要:[目的]考察大兴安岭野生笃斯越桔的适宜生境。[方法]根据大兴安岭野生笃斯越桔生物学特性及生境条件,利用数量化Ⅰ方法,通过对影响野生笃斯越桔株高生长和平均单株产量的8个环境因子的分析,研究野生笃斯越桔的适宜生境。[结果]影响野生笃斯越桔株高生长的主导因子依次为土壤类型、全氮含量、pH值、含水量、有机质含量、A层厚度;影响野生笃斯越桔平均单株产量的主导因子依次为土壤类型、全氮含量、有机质含量、pH值、含水量、A层厚度。样地聚类结果表明,研究区域样地可分为3种类型,以样地平均株高及平均单株产量作为笃斯越桔适宜生境衡量指标,表明第1类样地的生境条件最适宜。[结论]该研究为笃斯越桔模拟自然栽培技术提供了重要理论参考。[Objective]The study aimed to investigate the suitable habitat of wild Vaccinium uliginosum Linn in Greater Higgnan Mountains.[Method]According to the biological characteristics and habitat conditions of wild V.uliginosum,by using quantitative I method,the suitable habitat of wild V.uliginosum through the analysis on 8 environment factors influencing the high growth and average plant yield of wild V.uliginosum.[Result]The dominant factors impacting the high growth of the wild V.uliginosum in sequence were as follows:soil types,total nitrogen content,pH value,moisture content,organic matter content and A layer thickness.The dominant factors impacting the average plant yield of the wild V.uliginosum in sequence were as follows:soil types,total nitrogen content,organic matter content,pH value,moisture content,A layer thickness.The clustering results on the sample lands showed that the sample lands in the research area could be divided into 3 types.With the average plant height and the average plant yield of wild V.uliginosum in the sample lands as the measurement index for judging the suitable habitat of the wild V.uliginosum growing in the Greater Higgnan Mountains,the habitat conditions in first class sample land was the most suitable.[Conclusion]The study provided important theory reference for the resemble nature cultivation technique of V.uliginosum.
