Human activities, such as trampling and off-road vehicle, compact soil and affect the distribution of benthic macrofauna. 踩踏与越野车等人类活动都会压密土壤，也会影响底栖动物的生存与分布。
It is also found that the benthic communities need some time to stabilize after isolation, and then present apparent variation over time. 河流栖息地被隔离后，底栖群落经过一段波动周期后才表现出规律性变化趋势。
