摘要
生物多样性是指各种生命形式的资源,它包括地球上所有植物、动物、微生物物种及它们所有基因,以及生物与其环境相互作用形式的生态系统与生物过程,它包括三个层次,即遗传多样性、物种多样性与生态系统多样性[1]。生物多样性对人类生存与发展,以及对维持整个地球的...
The present research investigated the plant species diversity and distribution pattern of plants under the canopy and indicated that relative radiation intensity was the main factor that affected plant diversity under canopy in Larix kaempferi (Lamb.) Carr. community by using regression step by step anaiysis method and gray relavant analysis method . The results showed that relative radiation intensity the most suitable to keep high plant species diversity was 31% and the most suitable shadeing intensity was 0.65 in Larix kaempferi (Lamb.) Carr. community.
