摘要
Abstract
The Caragana aurantiaca community of the Yili River Valley situated on the riverbank marshes near the Jiefang Bridge of Tianshan town of Zhaosu county in Xinjiang. Investigated sample sites in this area, all the 64 species of plants belonged to 29 families, 6 growth forms of plant, 3 growth forms of root, 6 life forms, 5 ecological types of water. Among them, the species of Compositae and Gramineae respectively took the most of 14. 0% , and which of Leguminosae are 12. 5%. The species of upstanding type were 39. 0% of the growth form of plant, as well as those of divaricate type and tufty type were 25. 0% and 22. 0%, respectively. Among the growth form of root, the most of 50. 0% belong to taproot type, as well as brushy root type and rhizome type both reached 25. 0%. The life forms of the most belonged to geophyte which was 42. 0% , hemicryptophyte and therophyte were 33. 0% and 12. 5%. The species of mesophyte were the most of ecological type of water which reached 57. 8% ,and those of mesoxerophyte and mesophydrophyte respectively were 14. 0% and 12. 5%. In the marshes of Yili River Valley, the plants and roots took on the characters of middle temperate plant community and roots characteristics, the climate was typical middle temperate geophyte, and had a mesophytic habitat.关键词
