【摘要】：为了探讨长江中下游地区土壤节肢动物对林分类型的响应,2016年8月末对安徽省铜陵市横冲流域土壤节肢动物进行了调查,利用独立样本T检验分别对三种坡位下的两种林分类型土壤节肢动物群落多样性和土壤理化性质进行差异显著性检验。结果表明:(1)捕获的土壤节肢动物隶属7纲14目;(2)在上坡位,两种林分类型下的土壤节肢动物群落各指数差异不显著(P0.05);在中坡位,栎木林下的土壤节肢动物类群数(P=0.004)、多度(P=0.000)、Shannon多样性指数(P=0.005)和DG指数(P=0.021)显著高于杉木林,Simpson优势度指数(P=0.011)显著低于杉木林;在下坡位,栎木林下的土壤节肢动物类群数(P=0.046)、多度(P=0.000)和DG指数(P=0.032)显著高于杉木林,Simpson优势度指数(P=0.047)显著低于杉木林。
[Abstract]:In order to study the response of soil arthropods to stand types in the middle and lower reaches of the Yangtze River, a survey of soil arthropods in the Hengchong Valley of Tongling City, Anhui Province, was carried out in late August 2016.The diversity of soil arthropod communities and soil physical and chemical properties of two types of stands under three slope positions were tested by independent sample T test.The results showed that the captured soil arthropods belong to 7 classes, 14 orders and 2) in the upper slope position, the index difference of soil arthropod community under the two forest types was not significant (P 0.05), but in the middle slope position, there was no significant difference in the index of soil arthropod community under the two forest types.The number of soil arthropods under oak forest was significantly lower than that in Chinese fir forest (P _ (0.004), P _ (0. 000) (P _ (0.005)) and DG (P _ (0.021))), and was significantly lower than that in Chinese fir forest (P _ (0.011)), and in the downhill position, it was significantly lower than that in Chinese fir forest (P _ (0.011)).The number of soil arthropods and DG index (P0. 046) and DG index (P0. 032) of soil arthropods under oak forest were significantly higher than that of Cunninghamia lanceolata (P0. 047) and Cunninghamia lanceolata (P0. 047).
