摘要:

本文论述了保护昆虫多样性的意义、我国昆虫多样性的基本特点及面临的问题、昆虫多样性的保护战略和利用对策。文中强调指出,昆虫是生物界的一个主要类群,在我国,需要防治的害虫大约只占全部昆虫种类数的1%,其余种类对人类都是有益或者是中性的,它们不仅可以作为显花植物的传粉者、为人类提供食物和各种工业原料,而且可以作为许多害虫或杂草的天敌,以及用于环境净化和科学研究。我国由于地域辽阔,生境复杂,因此,昆虫种类极为丰富,珍稀物种及有益昆虫较多。然而,由于受到人类活动的干扰,我国昆虫多样性面临着生境遭到破坏,物种濒于灭绝,天敌大量减少等问题。为了有效地保护和利用我国的昆虫资源,作者提出了一些战略和对策。

Abstract

This paper dealt with the significance of conservation of insect diversity,the basic characteristics of insect diversity in China,the main problems of China's insect diversity,and the strategies for conservation of insect diversity in China.It was pointed out that,some 1% of all the described insect species in China are major insect pests,and the majority of insects are either directly or indirectly beneficial or neutral in their relationship to human beings.Insects pollinate crop plants;provide food for other animal and products for human consumption;serve as natural control agents of other pests,including insects and weeds;and contribute to the environmental purification and scientific research.China is rich in species of insects,and possesses many rare and valuable groups because of its vast territory and complex habitata.As a result of the interference of human's activities,however,China's insect diversity has been facing destruction of the habitat,near extinction of the rare species,and decreasing in natural enemies.In order to conserve and utilize China's insect resources more sensibly and efficiently,the author put forward a series of rational strategies.
