Plant diversity analysis of different altitudinal gradients in Shikuihe river, Yunnan province
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 9
Abstract
As the main river in Qiubei county, Shikui river plays an important role in local economic and environmental development. In this study, through the investigation and analysis of the diversity of plants in the shikuihe mountain area, the reasonable allocation of different altitude plants in the mountain area was achieved, providing theoretical basis for the later research. The results show that there are six typical communities in the range of 950-1200 m. Shrubs and herbaceous plants are the main types below the elevation of 1050 m, and trees and shrubs are the main types above the elevation of 1050 m. The basic change trend of the three indexes was the same, and the overall law of Simpson dominance index, shannon-wiener diversity index and Pielou evenness index was ＞ herb layer of shrub layer ＞ tree layer. The tree and shrub diversity was significantly affected by the altitude, while the herb was small. At the altitude of 1050 m, it was the community diversity index ＞ shrub layer ＞ herbaceous layer, while at the altitude of 1200 m the community diversity index herbaceous layer ＞ arbor layer. On the whole, the vegetation diversity in shikui mountain area decreases with the elevation increase.
