A study on vegetation and landscape of China and Japan

与日本暖温带地区相对应的中国调查区域包括浙江省、安徽省部分地区和上海经济区。在该地区的沿海、河滨、低地、高原和山区进行了植物社会学野外调查。共划分612个高架，分为森林、灌木、草地等100多种植被类型。进一步通过与日本植被的比较，系统化了植物社会学的层次结构。在中国东部和日本西部的常绿林带中，有许多相应的句法类群。日本茶树属是两国常见的分类学。日本圆齿花茶在中国没有分布，但在黄山分布着Sohayaki-element的替代类群。暖温带夏绿落叶林是湿润条件下或崩塌地的土壤顶极林，在中国分布较多。在日本第三纪晚期和中国东部低地有灭绝的当代物种。常见的植物社会学分类主要是次生草地群落，如蒿属植物（Artemisietea principis）、芒草属植物（Miscanthetea sinensis）、亚洲植物（planteinetea asiaticae）、三叶Bidentetea triparties和Chenopodietea。它们在人类活动的影响下分布，尤其是在农村景观周围。在进行植物社会学野外调查的同时，还进行了Sigmassociation调查，目的是对景观和土地利用进行分类。从92种signassociation材料中，24种景观单元通过表工作分类。这些排列对应着海岸线到内陆，低海拔到高海拔的线条，因此地形要素处于同一条线上，盐沼-海岸-池塘&湖泊-河床-低地-高原-山脉。明确了该地区潜在的自然植被，并在毛山市和上海市建设了环保林。中国科学家来日本的目的是为了与日本西部的植被进行比较。阐明了两国常绿森林不仅在物种组合上相互交织，而且在结构和动态上相互交织。少

The Chinese survey area corresponding to Japanese warm-temperate region includes Zhejiang province, the part of Anhui province and Shanghai economic area. The phytosociological field survey is carried out in seacoasts, riversides, lowlands, plateaus and mountains in this region. 612 releves are taken and classified into more than 100 vegetation types such as forest, shrub and grassland. Further through comparing with Japanese vegetation phytosociological hierarchy is systematized. There are many corresponding syntaxa between eastern China and western Japan in evergreen forest zone. Camellietea japonicae is common syntaxa in both countries. Japanese Fagetea crenate doesn' t distribute in China, however vicarious syntaxa of Sohayaki-element distributes in Mt.Huangshan. Warm-temperate summergreen deciduous forests which are edaphical climax forests on humid condition or collapsed site, are more divers in China. There are contemporary species that became extinct in Japan during Tertiary pe … More riod, in the lowland of eastern China. Common phytosociological classes are mostly secondary grassland communities such as Artemisietea principis, Miscanthetea sinensis, Planteginetea asiaticae, Bidentetea tripartitae and Chenopodietea. They are spread out under the human activity especially around the rural landscape.Phytosociological field survey at the same time the survey of Sigmassociation is carried out for the purpose of classifying landscape and land use. From 92 sigmassociation's materials 24 landscape units are classified through the table work. Those arrangement is corresponding to lines, seacoast to inland, low to high altitudes, therefore topographic elements stand in the same line, salt marsh-seacoast-pond ＆ lake-riverbed-lowland-plateau-mountains. Potential natural vegetation of this area is also clarified, and environmental protection forests are built at Maushan city and Shanghai.Chinese scientists came to Japan for the purpose of comparing with Japanese vegetation in the western Part. It is clarified that evergreen forests of both countries interosculate for not only species combination but also structure and dynamics. Less
