内蒙古贺兰山国家级自然保护区饲用植物资源调查

摘要

Based on the investigation and identification of plant samples collected in Helan mountainous area,and accessing relevant research about literatures on forage plant resource,the statistics and analysis of wild forage plant resources in Helan Mountains National Nature Reserve in Inner Mongolia is reported in this paper.The results show that in the Nature Reserve,there are 370 species of wild forage plant（including varieties,subspecies and forms）,belonging to 188 genera and 57 families.Among them,Herbs are 302 species,which account for 81.62% of the total of forage plants in the Nature Reserve.From the water ecological types,there are 199 species of mesophyte,which account for 53.79% of the total of forage plants in the Nature Reserve.There are 37 species for the superior,101 species for good,121 species for medium,and 91 species for the lower,20 species for inferior,respectively accounted for 10%,27.30%,32.70%,24.59% and 5.41% of the total species.From forage value,good forage and above plants are accounted for 37.30% of the total species,it can be seen that the forage plants have high value in Nature Reserve,which has a high potential of development and utilization.And in this paper,the suggestions has also been proposed for developing and utilizing the wild forage plant resource in the Nature Reserve.%在调查鉴定内蒙古贺兰山国家级自然保护区内的植物标本的基础上,结合查阅有关研究饲用植物资源文献,统计分析了保护区的野生饲用植物资源,结果表明,保护区内分布的野生饲用植物共有370种（含种以下单位）,隶属57科188属。其中草本植物占绝对优势,共计302种,占保护区内饲用植物总种数的81.62%;从水分生态型分析,中生植物最多,有199种,占保护区内饲用植物总种数的53.79%。从饲用价值上看优等37种、良等101种、中等121种、低等91种、劣等20种,分别占保护区内饲用植物总种数的10%、27.30%、32.70%、24.59%和5.41%。良等以上饲用植物占该保护区野生饲用植物总种数的37.30%,可以看出该保护区饲用植物价值高,具有很高的开发利用潜力。本文还对该保护区野生饲用植物资源的保护及开发利用提出建议。
