对日本暖温带湿润高草群落中几十个组成种的出苗和种子扩散的季节格局及其空间格局进行了测定。虽然观察到极高的空间异质性的出苗大多数物种，这可能是由于空间异质性的种子雨和“安全网站”的差异，出苗的季节模式是在一个物种内的空间和年之间的变化较小。群落年出苗开始于日积温（在一个基地上
Seasonal patterns of seedling emergence and seed dispersal as well as their spatial patterns were measured for several dozen component species of a species-rich moist tall grassland com- munity in warm temperate Japan. Although extremely high spatial heterogeneity of seedling emergence was observed for most of the species, which would have resulted from both the spatial heterogeneities of seed rain and 'safe-site' dis- tribution, the seasonal pattern of seedling emergence was less varied within a species over space and between years. Yearly seedling emergence in the community started when the accumulated daily air temperature (on a base
