Abstract: 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.
