带状皆伐后更新密度对植物多样性的影响
Effect of Regeneration Density on Plant Diversity afterBand Clear Cutting
摘要
Abstract
Aiming at the problem of loss biodiversity of Larix Olgensis plantation,five species of Quercus mongolica Fischer ex Ledebour,Quercus mongolica Fischer ex Ledebour,Juglans mandshurica Maxim,Picea koraiensis Nakai and Fraxinus mandschurica Rupr trees were artificially regenerated by two kinds of densities of 2 000 plants/hm2 and 3 300 plants/hm2 after band clear cutting of Larix olgensis henry in Meng Jiagang forest,Heilongjiang province.Two years later,the plant diversities of regenerated stand and without regeneration stand were investigated and analyzed respectively.The results showed that herb and shrub plant species of regenerated stand increased.The density,coverage and the average height were lower than without regeneration stand because the soil surface was destroyed due to the site preparation after clear cutting.After band clear-cutting of Larix olgensis henry forest,it was recommended to construct a mixed forest of needle and broad species with 2 000 plants/hm2 for its the better community diversity and more uniform individual species distribution关键词
