摘要
本文首次引入幂指模型（ｙ＝ ｙＬＭ ｅｘｐ（－ｂｄａ））来模拟害虫密度与作物产量间的关系，通过对１５组不同来源的害虫与作物竞争资料的模拟，证明幂指模型具有实际的生物学意义，能准确地描述多种害虫和多种作物间的危害关系，预测害虫危害作物可能造成的产量损失．为害虫的经济防治提供了一种新的研究方法．
This paper first quoted power-exponcnt model (y = yLM exp(-bda)) to fitting relations between pest density and crop yield, simulated 15 different source data of pests competed with crops and proved the actual biology significance of power-exponent model. It can describle accurately the damage relations of varied pest and varied crop, forecast the possible crop yield losses made by pests. It provided a new research method for economical prevention and control of pests.
