摘要
应用在甘肃省夏河县甘加高山草原的系统调查资料,对狭翅雏蝗的种群数量消长进行了模拟。结果表明, 狭翅雏蝗在草地的种群数量动态可用数学模型Nt=0.348 51t1.21333·e-0.02941t来描述。
In this paper, we systematically analysed the investigation data in alpine pasture in Xiahe county, Gansu province and made simulations about the population change of Chorthippus dubius (Zubovsky). The result showed that the population quantity change of Chorthippus dubius (Zubovsky) could be described by the mathematical model Nt=0.348 51t1.21335e-0.029 41t.
