【摘要】：為研究近自然森林經(jīng)營下的華北落葉松人工林不同林分類型對昆蟲群落多樣性的影響,以塞罕壩自然保護區(qū)內(nèi)的華北落葉松純林和混交林作為研究對象,對6種不同林分類型中的昆蟲群落結(jié)構(gòu)進行了研究。共獲得昆蟲標本9542頭,隸屬于7目,68科,187種,以雙翅目、半翅目和鞘翅目為優(yōu)勢類群。研究結(jié)果表明:6種林分類型中的昆蟲在物種和個體數(shù)上存在差異,相似性分析顯示群落結(jié)構(gòu)均不相似;群落多樣性指數(shù)分析表明華北落葉松純林和其它類型的混交林均具有較高的豐富度指數(shù)和多樣性指數(shù);主成分分析表明各林分類型中捕食性類群和寄生性類群是影響昆蟲群落結(jié)構(gòu)的主要因素,且捕食性類群和寄生性類群對植食性類群的控制作用較強;穩(wěn)定性分析顯示6種林分類型昆蟲群落結(jié)構(gòu)均具有較高的穩(wěn)定性。
[Abstract]:In order to study the effect of different stand types on insect community diversity of larch plantations under near-natural forest management, the pure and mixed larch forests in Saihanba Nature Reserve were used as the research objects. The insect community structure in 6 different stand types was studied. A total of 9542 insect specimens were obtained, belonging to 7 orders, 68 families and 187 species. Diptera, Hemiptera and Coleoptera were the dominant groups. The results showed that there were differences in species and individual number of insects in the 6 types of stands, and the similarity analysis showed that the community structure was not similar. Community diversity index analysis showed that both pure larch forests and other mixed forests had higher richness index and diversity index. Principal component analysis (PCA) showed that predatory and parasitic groups were the main factors affecting insect community structure, and predatory and parasitic groups had strong control over phytophagous groups. The stability analysis showed that the insect community structure of all the 6 forest types had high stability.
