| 摘 要： | 目的]探讨边缘效应对贺兰山东坡直翅目昆虫群落的影响。方法]样带法采集取样,记录不同种类及生境中直翅目昆虫的数量。结果]斑翅蝗科、斑腿蝗科和癞蝗科个体数量分别占总数的42.65%、29.15%和12.76%,构成研究区域直翅目昆虫的优势类群。直翅目昆虫数量沿疏林草地、边缘和荒漠草地依次增加,边缘多样性高于疏林草地和荒漠草地内部,且边缘与疏林草地差异显著;无论是疏林草地还是荒漠草地,直翅目昆虫群落多样性都是随着距边缘距离的增加而降低。在疏林草地-荒漠草地过渡带出现了栖息地广布种、利用边缘的栖息地广布种、利用边缘的栖息地特异种和逃避边缘的栖息地特异种4种边缘反应类型。结论]该研究可为直翅目昆虫生物多样性的保护和开发利用及保护生物学的发展提供数据和理论基础。
