樟翠尺蛾种群动态与植物群落结构及气候因子的关系

在昆虫种群的研究中,Ｇｉｅｉｒ和Ｃｌａｒｋ等曾经提出生命系统的基本概念1,2],认为生命系统由一个对象种群和作用于这个种群的环境所组成。控制昆虫种群增长的有密度制约因子(如食源)和非密度制约因子(如气候环境)。昆虫和植物之间的关系,历来是生态学研究的重要领域。通过长期的定点监测,研究某种昆虫种群动态与各种生态因子之间的关系,不仅可揭示动物和植物及环境之间互相影响的关系,对保护生物学理论的某些方面将有所发展,而且可为林业生产和环保工作提供如何应用生态学原理控制虫害,保护生物多样性和维护生态平衡的理论依据。樟翠尺…

The Interactions of Population Dynamics of Thalassodes quadraria and the Plant Community Structure and Climate Factors in Dinghushan

On the basis of long-term (eight years) monitoring for the population dynamics of Thalassodes quadraria Guene and the structure changes of plant community as well as the climate factors in the monsoon evergreen broad-leaved forest in Dinghushan Biosphere Reserve, the interactions among them were studied. As the food resources and habitats, plants have strong effect on the population dynamics of the moth. As a feedback, the population dynamics of this insect species caused the structure changes of the plant community. Climate factors, especially rainfall, contributed much to the mortality and reproduction of the moth.
