【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。
[Abstract]:The results of field investigation on grassland resources in Shaluoshan Mountain and taxonomic identification of plant specimens showed that 323 species of grassland plants (including subspecies, var. variabilis) were classified into 174 genera and 43 families. The gramineous species (65 species in total, 57 species in Compositae, 24 species in Leguminosae) and 45.2% of the total species in grassland were found in three families. According to the palatability criterion of forage, there were 48 species of herbivorous species and 69 species of herbivorous species. There are 113 species of forage, 62 species of edible forage, 18 species of reluctant forage and 13 species of non-feeding or poisonous plants. In the vertical distribution structure of natural grassland vegetation, 9 species of forage grass are the main dominant species to form representative grassland vegetation, and the grassland distribution, area and grass yield are analyzed. The general evaluation of natural grassland forage resources in Shalitao Mountain is as follows: the botanical composition is complex, the fine forage species are many, the gramineous forage species are the most, and the forage production is large; the grassland resources of Dactylis glomerataare prominent and the ecological and economic status is important.
