【摘要】 设置样点样地,以样方法对位于滇西北金沙江峡谷地区的丽江市退耕林地进行昆虫多样性调查和分析,探讨生境修复过程昆虫相及其变化。调查样地采集鉴定昆虫2240号,属于13目61科377种,主要为鞘翅目Coleoptera、半翅目Hemiptera、膜翅目Hymenoptera、直翅目Orthoptera、同翅目Homoptera、双翅目Diptera,共占总种数88.59%和总个体数量的96.11%。退耕林地、云南松林和农耕地的昆虫相呈现差异,以退耕林地的昆虫种类和数量最多。食叶及刺吸类昆虫在退耕林地中占具优势。退耕生态林地的昆虫多样性更相似于农耕地,而退耕经济林地昆虫相与云南松林较为接近。综合昆虫多样性信息结果来看,滇西北金沙江峡谷丽江退耕林地呈现正向生态恢复。更多还原

【Abstract】 Insect compositions and insect phase variations were analyszed.2240 insects were collected from sample plots in converting the cultivated land for forest located The Jinshajiang Gorge,Lijiang which can be classilied into 13 orders,61 families and 377 species.Moreover,insects belonged to Coleoptera,Hemiptera, Hymenoptera,Orthoptera,Homoptera and Diptera are 88.59%of total species and 96.11%of total individuals number.Insect phases of the converting the cultivated land into forest region differ from the natural Yunnan pine forest and farmland.Both insect species and numbers in the forest land converted from the cultivated land are more than the other investigated ecotope,and Defoliator and the phytosuccivorous insects have occupied a dominant position.Furthermore,insect diversity of ecological forest converted from the cultivated land is similar to the farmland,while insect phase of converted economical forest is closed to the Yunnan pine forest.Based on the recovery of insect diversity,conclusion can be drawn that the converting cultivated land into forest was useful for ecological restoration in The Jinshajiang Gorge.更多还原
