Ecosystem services in coastal sand dunes in Japan, present situation and restoration idea

本研究试图考虑日本稀有的天然草地--海岸植被的现状。在三因地区，天然海岸线保持完好，沿海沙丘因松林种植和农田建设而减少。原有的沿海植被也在很大程度上被摧毁了，在山因地区。建议在海岸沙丘遭到破坏和/或减少的地方，海岸植被容易部分保留，但其结构发生变化，生态色调功能可能丧失。

This study have tried to consider the present conditions of coastal vegetation that is rare natural grassland in Japan. In San-in district, natural shoreline was well left, the coastal sand-dune reduced due to pine forest planting and farmland making. Original coastal vegetation has largely destroyed also in San-in district. It is suggested that where a coastal sand-dune destroyed and/or was reduced, coastal vegetation may easy to be left partially, but its structure transformed, and the function of eco-tone may be lost.
