摘要
利用 1988～ 1997年对内蒙古锡林郭勒盟不同草原类型观测的牧草产量、地面气象数据及相关的NOAA气象卫星遥感资料 ,分别建立了草甸草原、典型草原和荒漠草原牧草估产模型。在此基础上 ,根据冷季的草地牧草残留量、牧草贮存量、草场利用率、家畜采食率、冷季天数及草地积雪情况等建立了草原冷季载畜量计算模型 ,为草原生态系统的良性循环提供科学依据。
By using the herbage yield, Meteorological data and RS information of NOAA meteorological satellite in 1988~1997 to establish the model for estimation of berbage production in meadow steppt, steppt and desert steppe in Xilinguole League of Inner Mongolia. According to the residues of herbage in pasture land, utilization rate, lovestock intake rate, and the situation of snow corer ete. in cool season to establish the model. Using it to calculate the carrying capacity in order to provide the scientific theory for management and sustainable development of the ecological system of grassland. It is useful for the control of macroscopically stocking rate in cool season and mitigate economic losses.
