摘要: 采用树高级种群分类,在一维和多维主导生态因子梯度上,提出了人工红松森林群落、人工落叶松森林群落,红松、落叶松种群生态位计算公式组:Nij(N1)=???(Pij*qij)1/2,Pij(SDR4)=B'+D'+C'+H'/4,qij(光)=(1-Ii)*Wij、qij(水)=K*Wij,qij(有机质)=Wij/Wmax,N(n)=√N12+N22+…+Nn2。计算结果表明,同林令最高树高级种群只出现在土壤含水率)25%、上壤有机质含量)6%的资源位上。

Abstract: Using connection analysis of grey theory, We got the dominant ecological factors affecting the productivity of artificial Korean Pine forest community and artificial Larch forest community. On one-dimension and multi-dimension graclient of dominant ecological factors, We advanced niche calculation formula group:Nij(N1)=???(Pij×qij)1/2,Pij(SDR4)=B'+D'+C'+H'/4,qij(光)=(1-Ii)×Wij、qij(Water)=K×Wij,qij(Organic matter)=Wij/W·N(n)=√N12+N22+…+Nn2,The calcalation results show that the highest tree-height grade population of the same aged appeared the resource niche that the soil water content exceeds 25%, soil organic matter content more than 6%.

Key words: Ecological niche, Korean pine population, Larch population, Tree-height grade, Artificial forest community.
