摘要
在草地生态系统中,年际间变化较大的气候条件(如降水、温度等),是草地初级生产力的决定因素。从1991年~2005年根据54个样点的牧草产量和当地气象因子的统计相关资料,建立牧草产量预报统计模式,为当地草原开发利用和畜牧业经济的发展,提供科学依据。
The primary productive capacity in the steppe ecosystem was determined by some climatic factors like rainfall and temperature that fluctuated yearly.The predict model of forage production was established based on the production and climate data monitored in fifty-four sites.This could provide some useful information for the local steppe use and economy development.
