Abstract:

In order to study Diversity of soil invertebrate communities of 25-30 years of tea planting area. A preliminary study was conducted at Tea Park Yushan Hill, a total of 1095 soil animal belonging to 4 phylums, 7 classes and 27 taxa. Among them, the dominant groups werer Nematoda, Acarina and Collembola, which amounted to 88.18% of total individuals; Common groups werer the Araneae, Protura, Hymenoptera and Lepidoptera sorts, amounting to 7.31% of total, other was rare groups. Three kinds of ecological environment of soil animal community structure analysis showed: the density were Tea Park 2＞Tea Park 1＞Tea Park 3; Number of groups were Tea Park 1＞Tea Park 3＞Tea Park 2; diversity(H') were Tea Park 3＞Tea Park 1＞Tea Park 2; Evenness (J) were Tea Park 3＞Tea Park 2＞Tea Park 1; Dominance (C) were Tea Park 1＞Tea Park 2＞Tea Park 3. The results also showed that similarity (q) of soil invertebrates The Tea Park1 and Tea Park 2 , Tea Park 1 and Tea Park 3, Tea Park 2 and Tea Park3 were moderate similar (0.75＞q＞0.50). Vertical distribution of soil invertebrate are concentrated in the surface.
