项目摘要

This study examines the characteristics of beach vegetation growing on the seawall side of beaches, between the front of the seawall and the shoreline, in the Fuji, Enshu, and Hichirimihama coasts, Japan. The effect on beach vegetation habitat zone of incident waves, wave run-Lip, and beach topography including beach slope at the shoreline is discussed for the three coasts. Also, the growable ground level from the mean seawater level where beach vegetation can grow is discussed on the basis of field data. The obtained results are summarized as follows(1)The ground level of the seaside edge of vegetation zone is a little different for different beach slopes. In the range of 1/10<i≦1/2, the vegetation ground level, Rv/Ho, is relatively high (on average 4.8 times as high as R/Ho), while in the range of 1/25<i≦1/10, the vegetation ground level, Rv/Ho, is on average 5.3 times as high as k/Ho.(2)In the Fuji, Enshu, and. Hichirimihama coasts, the ground level of the seaside edge of vegetation zone is related to wave run-up height and wave steepness by the diagram of Tsuchiya et al. based on the beach slope parameter.(3)The ground level at the seaside edge of vegetation zone is influenced by wave run-up and beach slope at the shoreline(4)The relative ground level at the seaside edge of vegetation zone is a different among the Fuji, Enshu, and Hichirimihama coasts.(5)For the vegetation growable condition, the ground level from the mean sea water level in common for the three coasts was determined by the arranged figures.

这项研究研究了海滩壁侧，海堤前部和海岸线之间的海滩植被的特征，富士，Enshu和日本的Hichirimihama Costas。针对三层外套的海滩植被栖息地区域的影响，包括海岸线的海滩坡度，包括海滩坡度。同样，根据现场数据，讨论了海滩植被可以增长的平均海水水平的地面水平的增长。所获得的结果总结如下（1）不同海滩插槽的植被区海边边缘的地面有点不同。在1/10 <i≦1/2的范围内，植被地面水平RV/HO相对较高（平均高达R/HO的4.8倍），而在1/25 <i≦1/10的范围内，RV/HO的植被接地水平为RV/HO，平均为k/ho（2）的5.3倍（2），fuji，Enshu，以及Enshu，和Enshu，和Enshu，和Enshu，和Enshu，和Enshu，和shsshu，和。 Hichirimihama大衣，植被区域的海边边缘的地面与Tsuchiya等人的图有关，与波长的高度和波钢有关。（3）植被区海边边缘的地面水平受海岸线的波浪和海滩坡度的影响（4）植物区域的海滨区域的相对地面水平在富士，恩苏（Enshu）和植物库中的河畔（5）在植被中的一层为单位的情况下是不同的。
