大通种牛场灌丛草地12种灌木植物隶属7科9属,优势种是金露梅、山生柳、狭叶锦鸡儿,草本植物主要是草地早熟禾、黑褐苔草、珠芽蓼、圆穗蓼、矮生嵩草。山地灌丛草地灌丛层平均高度126.6cm,盖度41.2%,草本层平均高度10.5cm,盖度71%,植物量207.3g/m2;高寒灌丛草地灌丛层平均高度80.0cm,盖度52.7%,草本层平均高度5.4cm,盖度89%,植物量218.6g/m2。灌丛草地植物群落层次分化明显,可分为高灌木层、低灌木层及草本层。金露梅、山生柳及狭叶锦鸡儿植物量分别为480.5g/m2、879.8g/m2、976.3g/m2。
Abstract:There are 12 shrubs species, among which belong to 7 families 9 genera in Datong cattle farm. The Potentilla fruticosa, Salix oritrepha and Caragana stenophylla are dominant,the Poa pratensis, Carex atrofusca , Polygonum viviparum, P.macrophyllum D.Don, and Kobresia humilis occupied dominant position in herbage. The high average value of bush on mountains bush-land is 126.6cm, the bush coverage is 41.2%, the high average value of herbage is 10.5cm, the herbage coverage is 71%, and the biomass is 207.3g/m2 ; The high average value of bush on alpine bush-land is 80.0cm, the bush coverage is 52.7%, the high average value of herbage is 5.4cm, the herbage coverage is 89%, and the biomass is 216.6g/m2. The space structure of bush-band is obvious, which is divided into 3 layers such as the highest bush layer, low bush layer and herbage layer. The biomass of Potentilla fruticosa , Salix oritrepha and Caragana stenophylla is 480.5g/m2,879.8g/m2,976.3g/m2。
