Plant sociological studies about planting environment on coastal reclaimed land (I)

This study aims at finding out the planting environment on coastal reclaimed land. In this investigation the plant communities and their succession on 3 types of soils (reclaimed land soil, reclaimed land soil mixed with loam, sandy soil) were studied in relation to PH, Chloride content, and water content of each soil. For this investigation vegetation survey in 83 places and soil survey in 16 places were held. The results obtained were as follows: 1. The environment for plantations is different each geographical feature. It is necessary to consider how to cover the reclaimed land with plants after examining the conditions of vegetation and then grasping nature environment 2. The main factor of environment for vegetation in this reclaimed land is supposed to be the size of soil grain rather than PH and Chloride content. 3. The appropriate way for plantations and the species of plant require consideration from the point of plant succession.
