摘要
依据环湖地区中心的铁卜加牧业气象试验站观测资料，以设计土壤潜在吸水系数、土壤潜在吸水量、降水指数和水分订正系数的计算为基础，从农业气象角度出发，选择水分订正系数对生长季大于或等于０℃的积温进行订正，得到气象积值，并根据数学生态学理论得出了环湖地区天然牧草群体生长动态数值模拟表达式。
Based on the observation data of Animal Meteorological Test Station of Tiebujia, on the basis of designing soil potential water absorbed coefficient, amount of soil potential water absorbed, precipitation index and the calculation of water corrected coefficient, choosing water corrected coefficient to correct the ≥0 ℃ accumulated temperatures in growth season and the meteorological acumulation value had been obtained; and according to mathematical ecology principle, a dynamic simulation model for colony growth of natural herbages around Qinghai Lake shore had been established.
