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。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: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%.
