| Abstract: | A survey was conducted on species,quantity,coverage and height of undergrowth vegetation in a Larix principis-rupprechtii plantation.Effect of thinning intensity on the biodiversity of undergrowth vegetation was studied by Simpson index,Shannon-Wiener index and Gleason index.Results showed that the species and quantity of undergrowth vegetation in the L.principis-rupprechtii plantation gradually increased with increasing thinning intensity.The species of undergrowth vegetation in sample plots under differen... |
