Study On Wild Plant Resources Of Arhorqin Grassland Nomadic Grazing System In Inner Mongolia

Arhorqin Grassland Nomadic Grazing System in Inner Mongolia was identified as an important agricultural cultural heritage of China by the Ministry of Agriculture in 2014.The paper conducted the research on local wild plant resources in Hundlen Summer Herding place which is one of the core areas of the grassland nomadic system.The results: there are 196 species,1 subspecies,4 varieties and 1 forma of wild plants,which belonging to 52 families and 138 genera.Among them,Compositae is dominant,followed by Rosaceae,Gramineae,Leguminosae,Liliaceae,Ranunculaceae,Polygonaceae,Cruciferae,Labiatae,Salicaceae and Umbelliferae.The number of plant species of these 11 families accounts for 67.32% of the total species of wild plant resources in the study area,indicating that the plant species in this area are mainly concentrated in the minority families;Seeing from the Life form,the herbs are absolutely dominant in total plants including 155 species 1 subspecies 2 varieties and 1forma species,which accounted for 78.47% of total wild species.The woody plants are in second place,with 36 species and 1 variety,accounting for 18.32% of the total species.Seeing from the water ecotype,mesophytes is dominant,including 141 species 1 subspecies 3varieties and 1forma species,accounting for 72.28% of the total wild plants in the area,followed by xerophytes,with 51 species and 1 variety,accounting for 25.74%,indicating that the climate of this core area is relatively humid with better water conditions.According to the common classification method of wild plant resources and combining with the whole structures and the characteristics of wild plant resources in this study area,the paper classifies the wild plant resources of the Arhorqin Hundulun campsite into 7 categories and 16 subcategories.The statistical results show that there are 145 species 1 subspecies 4 varieties and 1forma of wild forage plants;139 species,1 subspecies and 4 varieties of wild medicinal plants,73 species and 3 varieties of wild edible plants;82 species and 1 variety of wild industrial plants;72 species 2 varieties and 1 forma of wild environmental plants;8 species of wild cultural plants;3 species of rare wild plants.From the perspective of the composition of wild plant resources,wild forage plants are dominant,followed by wild medicinal plants.Hundlen Summer Herding place is one of the main summer grazing place for local herders.Therefore,wild forage plants are the most important resources used by local herders.There are 147 species,3 varieties of wild forage plants belonging to 40 families and 98 genera in this area,accounting for 70.33% of the total plant species in the study area.The wild forage plants in Hundulun campsite are classified according to the comprehensive evaluation method of wild forage plant resources and the results show that there are 12 species,1 variety excellent forage plants,37 species 1 variety good forage plants,moderate feeding plants with 45 species 2 varieties,low feeding plants with 43 species 1 variety and 7 inferior forage plants,respectively accounting for 8.73%,25.50%,31.54%,29.53% and 4.70% of the total species.The results show that the main forage plants used in the study area are moderate feeding plants and low feeding plants.The plants in the two levels contain 90 species and 2 varieties,accounting for 61.34% of the total species.Arhorqin grassland nomadic system as a national agricultural cultural heritage has a high protection and research value.Hundlen Summer Herding place is one of the main grazing places for local herders,so this paper aims to give some advice of protection and sustainable use of local wild plants based on local situations and results of the survey.
