不同植物类型昆虫群落结构的研究

Studies on the Structure of the Insect Communities in Different Plant Types

研究了4种不同园林植物类型内昆虫群落的组成、结构及多样性的变化。研究结果表明，构成复杂的植物类型内昆虫群落种类丰富、结构复杂、多样性指数高；反之则相反。而且复杂植物类型内昆虫群落数量变化规律明显，排序结果显示其变化可在时间过程中明显区分为几个阶段；简单植物类型内昆虫群落变化无明显规律性。

The variation of the composition, strueture and diversity of the insect communi-ties in four type of garden plants are studied. The results showed that the inseet community had more rich species, more complieated strueture and higher diversity index in the compli-cated plant type than those in the simplc plant type. And the number variation of the inseet community had obvious regular pattern in the complicated plant type, the Ordination analy-sis demonstrate that the variation can be divided in to several stages obviously in the course of time. But in the simple plant type the variation of the insect community had no obvious regularity.
