Study On Flora And Resources Of Seed Plants In Ejina Banner

Ejina Banner is adjacent to the Badain Jaran Desert.In winter,the climate is cold,the summer is arid and rainy,and there is a large temperature difference between day and night.It is perennially affected by sandstorms.This article analyzes the literature data,collects data in the field,applies the principle of flora geography,and analyzes the flora of the Ejina Banner seed plant according to the plant resource classification system.The results showed that there were 54 families,195 genera and 431 species of seed plants in Ejina Banner.The distribution types were mainly temperate components,and the families,genera,and species of temperate distribution types accounted for 22.23%,53.17%,and46.41% of the non-world distribution numbers,respectively,and were the main components of the Ejina Banner seed plant flora.In the plant life type,herbaceous plants have obvious advantages,especially perennial herbs,accounting for 44.55% of all seed plants.The mesophytes are the main type of water ecology in this area,accounting for63.57% of the total number of plants in the area;Status,accounting for 33.41% of the total number of plants in the area.Among the plant resources in this area,116 kinds of medicinal plant resources accounted for 26.91% of the total number of plants in the area;106 kinds of protein and amino acid plant resources accounted for 24.59% of the total number of plants in the area;40 kinds of garden ornamental plant resources accounted for There are 9.28% of the total number of plants in this area;there are 34 kinds of fiber plant resources,accounting for 7.89% of the total number of plants in the area;30 kinds of oil plant resources,accounting for 6.96% of the total number of plants in the area.Other plant resources are relatively scarce.The total number of plant resources occupied by starch plant resources,vitamin plant resources,aromatic oil plant resources,plant gums and pectin plant resources,plant material resources,and energy plant resources are all in the total number of plants in this area 5% the following.Since ancient times,Ejina Banner has a poor natural environment and low ecological functions.In recent years,it has been continuously destroyed by humans and the ecological environment is extremely fragile.This paper systematically analyzes the seed flora of Ejina Banner and provides a scientific basis for the protection and utilization of the seed plant resources in this area.
