埋立地の植生 : I.植物群落と微地形

抄録

This report deals with the vegetation in a reclaimed land area developed from the sand pump dredging of marine sediment. In areas where precipitation exceeds evaporation, it is generally thought that desalting is completed after 4-5 years and no halophytic vegetation will glow. In this area, however, there was an unexpected growth of halophytic vegetation, although there was evidence of desalting in some places. The halophytic vegetation showed a sequence which roughly resembled a concave microrelief. Other factors besides the microrelief were also taken into consideration. At present it is no more than an assumption that the method of reclaimed land construction or the materials used could have been influential factors. Future studies are needed to elucidate the vegetation-soil microrelief relationship of this area. In this initial report we discuss the occurrence of vegetation in relation to its environment.
