    摘要:

    飞蝗有迁移和聚集习性,在取食特别是成虫产卵时有明显选择生境的能力,但就种群动态的数量变化过程而言,则具有自我调节的特征,马世骏等在种群密度与生物学特性,天敌、食物及空间因素等对种群增长的反馈作用方面,已分別有所阐述(马世骏等,1965a、1965b)。本文以湖区为例,进一步从系统生态学观点阐明“改”与“治”在根除蝗害中相辅相成的作用。

    Abstract:

    The present paper deals with the characteristics of Oriental Migratory Locust from the ecosystem point of view and the eco-economic basis for the control strategy, and a lake ecosystem is taken into consideration, as an illustrative example.Specifically, it comprises three parts. The first part is the natural regulatory mechanism of the population. This mechanism is achieved by three feed-back systems, namely, intraspecific interference of population crowding, environmental influences and natural enemies. I...
