The main meteorological factors of formation and development of mire meadow of qinghai lake drainage area

摘要

Qinghai Lake is located in the northeastern Qinghai-Xizang(Tibet) Plateau. It is an es- pecially big light saltwater lake. The mire meadow in Qinghai Lake drainage area is an eco-system which is affected by the eco-environment factors. Its formation, development and temporal and spatial distribution law are decided y a few main meteorological factors in the eco-environment to a certain extent. The main meteorological factors are ≥ 10 deg. C accumulated temperature, precipitation from May to September and annual humidity coefficient. The mathematical model of the mire-wetland rate and the main meteorological factors is given by multivariate linear regression in the paper.
