Analysis on the Composition and Resources of Seed Plants in Wild-fruit Forests in the Large Xigou and Small Xigou Valleys in Huocheng County, Xinjiang

According to the investigated results, there are more than 500 species of seed plants in 233 genera and 60 families in wild-fruit forests in the Large Xigou and Small Xigou valleys, Huocheng County, Xinjiang, China. In the study area, it is rich in wild plant resources, and the statistical results show that there are 38 species of wild fruit trees, 30 species of edible plants, 60 species of forage plants, 111 species of nectariferous plants, 128 species of ornamental plants, 50 species of perfume plants and 113 species of medicinal plants. In which 9 species are the key protected plants at national level, 9 species at autonomous region level, and 3 species are the rare plants on the brink of extinction. In this paper, the advantages and disadvantages of the physical geographical and ecological conditions for the growth and survival of Prumus diuaricata Ldb. in the Large Xigou and Small Xigou valleys are analyzed, and the distribution and multiplication of the wild-fruit trees and the vegetation and habitats are discussed based on the filed investigations. Moreover, the composition and basic characteristics of seed plants in the study area are researched, the plant species and their properties as well as the utilization of plant resources are lucubrated, and the brink of extinction of Prumus diuaricata Ldb. in the Large Xigou and Small Xigou valleys is analyzed from many aspects. It is suggested to establish a nature reserve of Prumus diuaricata Ldb. in the Large Xigou and Small Xigou valleys, and some suggestions are put forward for conserving the plant species on the brink of extinction.
