Studies on the Planting method for the Establishment of Seaside forest and Reclined foreshore land

根据1986年至1989年3年的调查结果，在内海国家公园区及周边地区积极加入植物演替促进技术，以创造“绿色”景观，并将林地的处理总结如下：(1)在松木枯死的林地土壤中，现有植被种下的泛欧花、白杨、小苞叶、马柳和松木的幼苗容易生长。死于长时间不降雨。此时林地土壤的pF值约为3.5 ~ 3.8。(2)松树枯死后的林床或叶盖是否存在与林下植被交错的情况，对松树幼苗的产生和生长有影响。(3) 1987年异常干旱期自然生长的红松幼苗全部死于裸露的土壤区，但35-5%的生长个体分布在林下植被生长的周边地区或有叶面覆盖的林地。

Vegitative succession promoting technique is positively added for the purpose of the creation of "Green" landscape in the Inland Sea national park district and peripheral regions in the future on the basis of the results of investigation for three years since 1986 up to 1989 and the treatment of a forest land is summarized as follows.(1) In forest land soils wherein the overwood of a pine was dead, the seedlings of Eurya japonica, Vaccinium oldhami, Vaccinium bracteatum, Mallotus Japonicus and a pine in the existing vegitation species are easily. dead by non-rainfall extending over a long period of time. The pF value of forest land soils at this time showed about 3.5-3.8.(2) The presence of the forest bed or the leaf-cover strudded with undergrowth vegitation after the pine withering has effect on the generation of pine seedlings and the growth thereof.(3) All individuals of naturally grown this-year-old pine seedlings were dead inbare soil areas by the abnormal dryness in 1987 but it was found that about 35-5% of grown individuals existed in peripheral areas, where undergrowth vegitation was grown, or forest land with confirmed leaf-cover.
