摘要
本文从玉米地中、玉米地周围、周围大尺度这三个层次范围综述了非作物植被对玉米地节肢动物群落的影响。在不同尺度上,非作物植被对玉米地节肢动物群落影响的形式不同。在玉米地中,杂草等覆盖物能够增加天敌种类和数量,减少害虫的危害,但是杂草等覆盖物的存在同时也可能有利于害虫的发生;在玉米地周围,非作物植被可以为天敌提供栖息、越冬、捕食等场所,可以作为天敌"库"的场所;在周围大尺度上,非作物植被与作物的种植面积的比例影响着玉米地中节肢动物群落的动态,某些节肢动物可能对某一特定范围内的植被组成有响应。本文还浅析了非作物植被影响玉米地节肢动物群落的机理,并对相关问题进行了讨论。
The effect of non - crop vegetation within- farm and landscape levels on arthropod in different habitat scales which include within- crop, communities in maize fields was summarized. The way that non -crop vegetation takes effects on arthropod communities in maize fields varies with the different habitat scales. At the within- crop scale, weeds and other coveries benefit natural enemies and reduce the pest damage. But non -crop vegetation can also benefit pests. At the within -farm scale, non -crop vegetation can serve as the place for arthropods to rest, overwinter and prey, thus it acts as the convenient ＂pool＂ of natural enemies. At the landscape scale, the ratio of the area of non - crop vegetation to crop vegetation affects the dynamics of the arthropods respond to the vegetation composition only at the vegetation on arthropod communities in maize fields discussed. arthropod community in maize fields. And some some specifical scale. The effect mechanism of was analyzed, and some relative problems were
