摘要: 本研究统计分析了青海省50个气象台站1961-2006年的气象资料,利用改进后的综合顺序分类法划分了青海草原类型第1级-“类”。根据划分结果将全省草地划分为11类,基本符合青海草地类型分布特征,说明了改进的综合顺序分类法在青海进行植被类型划分是可行的。选择刚察、玛多、格尔木3个有代表性的地区,统计分析了它们的湿润度K值和>0℃年积温的变化趋势,同时分析了草场的演替趋势。

Abstract: Meteorological data of fifty observation stations from 1961 to 2006 were analyzed. Based on the principles of advanced comprehensive and sequential classification, the first grade grasslands of Qinghai, were classified into 11 classes, which agreed with the features of Qinghai grasslands. This showed that it was feasible to classify Qinghai grasslands and three typical regions were chosen to analyse their trends, K value (wetness degree), accumulated temperature over 0℃, and grassland succession.
