長(zhǎng)白山自然保護(hù)區(qū)北坡及南坡甲螨多樣性組成比較研究

長(zhǎng)白山自然保護(hù)區(qū)北坡及南坡甲螨多樣性組成比較研究摘要：

甲螨是長(zhǎng)白山地區(qū)重要的無(wú)脊椎動(dòng)物群體，對(duì)維持該地區(qū)生態(tài)系統(tǒng)平衡和資源的合理利用具有重要意義。本文通過(guò)對(duì)長(zhǎng)白山自然保護(hù)區(qū)北坡及南坡甲螨多樣性組成進(jìn)行對(duì)比研究。

研究結(jié)果表明：長(zhǎng)白山北坡甲螨共分為6個(gè)科、16屬、28種；長(zhǎng)白山南坡甲螨共分為7個(gè)科、18屬、34種。南坡甲螨物種數(shù)量和屬的個(gè)數(shù)均高于北坡。長(zhǎng)白山南坡橙綠美螨、紅全盤美螨、瑞金胡椒美螨為該區(qū)域特有種。兩坡中均出現(xiàn)鹿角狀皮螨、無(wú)耳銼甲螨、溝牙肉刺螨等共有種。長(zhǎng)白山北坡和南坡甲螨多樣性相對(duì)較低，其中以狹鱗繭蜱、瘤繭螨、白肋瓢螨等常見(jiàn)種占據(jù)主導(dǎo)地位。

本文在對(duì)比研究的基礎(chǔ)上，探討了長(zhǎng)白山地區(qū)甲螨多樣性的影響因素，發(fā)現(xiàn)海拔高度、植被類型、環(huán)境溫度等因素均可能對(duì)甲螨的多樣性產(chǎn)生影響。
