摘要
本文以内蒙古东胜区泊江海镇覆沙地3种不同盖度沙柳林和柠条沙柳混交林行间植物为研究对象,在典型样地内采取样方法对行间植物特征进行研究,结果表明:随灌木林盖度增加,植物种数、一年生草本植物重要值、中生植物重要值、植物多样性指数和丰富度增加,多年生草本植物重要值、旱生植物重要值降低;灌木重要值为低盖度柠条沙柳混交林>低盖度沙柳纯林>中盖度沙柳纯林;均匀度为中盖度沙柳纯林>低盖度沙柳纯林>低盖度柠条沙柳混交林。
The paper studys the interrow growth of Salix psammophila,mixed forest of Caragana intermedia and Salix psammophila which have 3 different sorts of coverage in sand covered plot of Bojianghai Town in Dongsheng Area of Innera Mongolia and survey the characteristic of it by using the method of sampling in typical sample plots.The result indicated that the quantity of plant species,the important value of ageratum houstonianum,mesophyte,the diversity index and the species richness increase along with coverage of Shrub while the important value of penenial herb and xerophyte decreased;The important value of shrub in mixed forest of low-coverage Caragana intermedia and Salix psammophila is the biggest of all and pure forest of low-coverage Salix psammophila is bigger than pure forest of medium-coverage Salix psammophila.The evenness of pure forest of medium-coverage Salix psammophila is biggest of all and pure forest of low-coverage Salix psammophila is bigger than mixed forest of Caragana intermedia and Salix psammophila.
