At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.

结果表明：秋季鼠类对种子的捕食压力大，使得种子在无保护的情况下很少存活到出苗；而秋季覆网保护和完全保护（覆网一直保留到第二年10月调查时为止）均增加了直播种子的存活和出苗率；将种子埋藏在土壤1-4cm也显著增加直播种了的存活率和出苗率，这与鼠类密度(12%)在秋季显著高于春季(2%)有直接关系。
