    Being the age of urbanism, urban designers are requested to prepare answers on many metropolitan problems.
    The writer intends to research a key on urban green problems, with studies on citizens' recreational habitation at greens.
    As a result to study their recreational utilization, follows are concluded.
    An urban hierarchy of 2-3 h. a. space is a community of heighbourliness, and has to be accomodated with a pre-teenager's playlot, according to their max. sphere of action; i, e, radius of 0.1km.
    Next urban hierarchy of 20-30 h. a, space is a community of daily shopping, and has to be acco-modated with a low-teenager's playground, that is concluded with their max. sphere of action;i, e. radius of 0.3km.
    Third urban hierarchy of about 2km2 space, which comes with the max. sphere of action in citizens' usual recreational walking or in whose human locality sense, is a community of cmmon shopping, and has to be accomodated with a neighbourhood park
    This space 2km2 is also concluded with their usual sphere of above actions; i, e, radius of 0.7km. Remarks

    This study aims at the finding out some trees suitable to the reclaimed land soil in Hachirogata lagoon.
    For this experiment 7 species were prepared: Populus nigra var, italica, Zelkova serrata, Ulmus Davidiana var, japonica, Platanus orientalis, Robinia pseudoacacia, Pinus thnubergii and Cryptomeria japonica.
    The results obtained were as follows:
    (1) All trees except Populus grow better in the plot covered with field soil by 15cm and 30cm deep than in the reclaimed land soil.
    2) Only Populus shows the best growth in the reclaimed land soil.
    (3) Fertilization effect can not yet be seen in this experiment.
    (4) Generally speaking, Populus and Pinus are comparatively suitable species in the reclaimed land soil.
