Invading and spreading manners of broad-leaved tree species into coastal Pinus stands were studied in Hokuriku and South Thohoku district in Central Japan. 102 tree species and 88 herb species were appeared and especially Prunus, Quercus and Rhus were typicla genera in those areas. Canopy gaps which created by the blighted pine trees were filling up with broad-leaved tree species.In artificial Pinus densiflora stand on sand dune, the under vegetations were divided into 3 types. The patch community type which mainly consisted of Rhus trichocarpa was successional seral community from the no undergrowth type to the type dominated by broad-leaved tree species.Seedfall, germination and survival of Pinus densi-flora and some broad-leaved tree species were surveyed in each community types.Reproductive behaviors on Rhus trichocarpa, Prunus apetara var. pilosa and Quercus serrata were profitable for spreading on space and time in seral communities.Seed of Quercus serrata and that of almost all tree species were dispersed by murid rodents and birds, respectively. Mechanisms on spreading the broadーleaved tree species were discussed.

在日本中部的北陆和南东北地区，研究了阔叶树种对海岸松林的入侵和扩散方式。结果表明，该区共有乔木102种，草本88种，其中以李属、栎属、漆树属为代表。枯梢松树造成的林隙被阔叶树种所填充，沙丘人工赤松林下植被可分为3种类型。以漆树为主体的斑块群落类型是由无林下植物群落向以阔叶树种为主的演替演替系列群落，对各群落类型中赤松和部分阔叶树种的种子落地、萌发和存活情况进行了调查。在演替系列群落中，毛叶栎和锯缘栎在空间和时间上都有利于种子的传播，锯缘栎和几乎所有树种的种子分别由鼠类和鸟类传播。并对阔叶树种的推广机制进行了探讨。
