| 摘 要： | 农田边界 (田埂ｆｉｅｌｄｂｏｕｎｄａｒｙ)可定义为农田(作物田块 )间过渡带 (ｅｃｏｔｏｎｅ) 4 ] 。不同类型农田边界所包含的景观要素不同。农田边界包括的景观要素有树篱、防护林、草带、墙、篱笆、沟渠、道路、作物边界带等。半自然生境的农田边界是重要的动植物栖息地和扩散廊道6] ,而农田边界的生物多样性和物种的扩散 ,又受边界结构属性、农作系统及农作措施和区域景观结构及动态的影响1,7] 。随着人口的增加和农业集约化的发展 ,农业景观中非生产性(半自然生境 )用地面积逐渐减少 ,在一定程度上引起生物多样性下降及影响农田…

| Abstract: | Biological community including carabids and spiders were investigated in 30 various fields margins and 10 related fields by pitfall trap in Quzhou area of North China Plain.It was concluded that biodiversity index and numbers of biological groups in field margins are higher than those in the related crop fields.There is a given relationship between the attributes of field margins and biodiversity.The control of structure and vegetation in field margins would be the possible way to protect natural enemy such as carabides and spiders. |
