摘 要：
对沙尔套山草地资源实地调查资料总结和采集植物标本进行分类学鉴定统计的结果表明:共有草地植物323种(包括亚种、变种),分归为43科174属,其中禾本科种数最多(共计65种),其次是菊科57种、豆科24种,三科的种数占全部草地植物种数的45.2%;按照牧草适口性标准,划分特别喜食牧草有48种,喜食牧草有69种,乐食牧草有113种,可食牧草有62种,不愿采食牧草有18种,不食或有毒植物13种。在天然草地植被垂直带分布结构中,有9种牧草为主要优势种组成了具有代表性的草地植被,并分析了以这9种牧草为主构成的草地分布、面积和产草量。对沙尔套山天然草地牧草资源总体评价是:植物学成分复杂,优良牧草种类多;禾本科牧草种数最多,饲草生产量大;鸭茅(Dactylis glomerata)草地资源优势突出,生态和经济地位重要。

摘 要：
Plant species in Shaertao Mountains were collected and identified taxonomically.The results showed that there were 323species(included subspecies and varieties)in grassland vegetations,classified into 43 families,174genera,65 belonged to Gramineae,57 belonged to Asteraceae and 24 belonged to Leguminosae,plants in these three families accounted for 45.2% of the total specie in grassland vegetations.According to forage palatability,48 species were the forages of special favorite to eat,69 species were forages of favorite to eat,113 species were forages of wanted to eat,62 species were forage of edible to eat,18 species were forages of not wanted to eat and 13 species were of forage of poisonous plants.There were9 species that was major dominant species,they formed local representative grassland in nature grassland vegetation perpendicular band distribution structure,and the distribution,area and productivity of grassland were analyzed.The overall assessment of Shaertao Mountains natural grassland had very complex botanical ingredients,many kinds of excellent forage,large numbers of Gramineae species,high production of forage,significant advantage of Dactylis glomerata grassland resource and important ecological and economic status.
