| 摘 要： | 在有害生物治理中以生态学与经济学原理为出发点,建立“可持续阈值与经济利益回收”模型,提出有害生物治理中的生态成本(Ce)、整合成本(Ci)、净收益速率(r)、固有收益速率(r*)等概念,据此发展一种以可持续阈值作为临界点调查虫口密度的新的参考方法,并对模型的有关参数作了讨论. |
| 关 键 词： | 经济利益回收 收益速率 生态成本 可持续阈值 |

| Abstract: | Based on the principles of ecology and economics in pest management,this paper established the model of sustainable threshold and economic profit acquirement,proposed the definitions of ecological cost C_e,integrated cost C_i,net acquirement velocity r,proper acquirement velocity r~* and so on,developed a new reference method surveying the pest-insect population density based on the critical point of T_s.With this model,it tried to discuss the parameters. |
| Keywords: | economic profit acquirement acquirement velocity ecological cost sustainable threshold |
