摘要
以内蒙古天然草场为研究区域,利用2004~2008年生长季牧草产量观测资料和能够综合反映光、温、水对牧草生长影响的气象条件指数,分析了内蒙古主要天然草场牧草产量与气象因子之间的关系,并分别建立了适用于不同草地类型（温性草原类、温性草甸草原类、低地草甸类、温性草原化荒漠类、温性荒漠草原类）的牧草产量气象估算模型。经过验证,所建产草量估算模型具有良好的估测能力,准确率较高,可以满足应用需要。
The natural grassland in Inner Mongolia was the study area.Based on the growing season grass biomass data observed from 2004 to 2008 and the meteorological condition index which can reflect the influence of precipitation,air temperature and sunlight on grass,the relationship between the grass yield and the meteorological factors were analyzed and the meteorological estimation model for forage yield in different natural grassland types（warm steppe type,temperate meadow type,lowland meadow type,temperate steppe desert type,temperate desert steppe type） were also established.After verification,the established meteorological estimation model for forage yield had a higher accuracy,and can meet application needs.
