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(P>0.05);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。
In order to investigate the response of soil arthropod to the stand types in the middle and lower reaches of the Yangtze River, soil arthropods were surveyed in Hengchong watershed, Tongling City, Anhui Province in late August 2016. T-test was performed on two types of soil samples The differences of soil arthropod community diversity and soil physical and chemical properties in forest stand were tested. The results showed that: (1) The captured soil arthropods belonged to 7 classes and 14 orders. (2) In the uphill position, there was no significant difference in index of soil arthropod communities between the two forest types (P> 0.05) (P = 0.004), abundance (P = 0.000), Shannon’s diversity index (P = 0.005) and DG index (P = 0.021) under oak forest were significantly higher than those of Chinese fir plantation and Simpson’s dominant (P = 0.011) was significantly lower than that in Chinese fir plantations. The number of soil arthropod groups (P = 0.046), abundance (P = 0.000) and DG index (P = 0.032) Chinese fir plantation, Simpson dominance index (P = 0.047) was significantly lower than that of Chinese fir plantation.
