摘要: 青海湖是一个较特殊的巨大微咸水湖。青海湖流域沼泽化草甸具有明显的湿地生境特征,其形成发育和时空分布的主要气候因子是大于等于10℃的积温和5月至9月的降水及年湿润系数。根据主要气候因子作出了湿地率与该环境形成发育的主要气候因子的数学模型。

Abstract: Qinghai Lake is located in the northeastern Qinghai Xizang (Tibet) Plateau.It is a special big light saltwater lake.Paludification meadow in Qinghai Lake drainage area is an eco-system affected by the eco-environment factors.Paludification meadow in Qinghai Lake drainage area have obvious wetland habit features,is the component of Qinghai Lake wetland.Its formation,development,and spatial and temporal distribution are governed by a few main meteorological factors in the eco-environment to a certain extent.The main meteorological factors are ≥10℃ accumulated temperature,precipitation from May to September and annual humidity coefficient.The mathematical model of the mire wetland rate and the main meteorological factors are given by multivariate linear regression in the paper.
