The restoration of burrow systems is one of the key indices of the restoration of plateau pika (Ochotona curzoniae) populations, changes of burrows distribution can reflect population dynamic. We measured the density of plateau pika, the density of burrows and those burrows relative positions in a 2.79 hm2 alpine meadow during 2014-2016 in Qilian country of Qinghai Province, in which six 50m×50m plots with lethal and block control, six 30m×30m plots with lethal control and three 50m×50m plots as control group. The average nearest neighbor and mean crowding index was used to analyze the distribution pattern and clump areas of available burrows, abandoned burrows, fecal pits and sportive pits respectively，and descriptive and correlation analyses were conducted between parameters. The results show that: during the restoration of plateau pika (ⅰ) The distribution pattern of available burrows changed from random to dispersed, abandoned borrows changed from random to clustered, fecal pits and sportive pits displayed no obvious changing trends; the restoration of available and abandoned burrows toward its original distribution patterns before lethal control, but both of them restored inadequately. (ⅱ) The average nearest neighbor index of available burrows was positively correlated with density, abandoned burrows were negatively correlated with density, fecal and sportive pits displayed no obvious correlation with density; and only fecal pits have a significant negative relationship with population density. (ⅲ) The clump area changing trend of available burrows is well consistent with fecal pits and sportive pits, and in compensating situation with abandoned burrows; and the variability of burrows clump area is much less than their density. It declared that: (ⅰ) Hysteresis exists in burrows distribution pattern and burrows density during the restoration of plateau pika. (ⅱ) The distribution pattern of available and abandoned burrows are mostly decided by their density. (ⅲ) Plateau pikas have more urgent demand for burrow system area than burrow numbers during restoration.
