A study on vegetation and landscape of China and Japan

与日本暖温带相对应的中国测区包括浙江省、安徽省部分地区和上海经济区。在该地区的海岸、河边、低地、高原和山区进行了植物社会学的实地调查。共采集612个样方，划分为森林、灌丛、草地等100多个植被类型。并通过与日本植被的比较，系统地归纳了植物社会学的等级。中国东部和日本西部万年青林区有许多对应的合生类群。山茶花在这两个国家都是常见的合生类群。日本毛茛在中国没有分布，但黄山分布有Sohayaki成分的替代组合。暖温性夏绿落叶林是我国分布最广的一类森林类型，是在湿润条件下或崩塌地形成的土壤顶极林。在第三纪时期，日本有一些现代物种灭绝了。 ...更多信息 位于中国东部低地的里奥德。常见的植物社会学分类主要是次级草原群落，如Artemisietea principis，Miscanthetea sinensis，Planteginetea asiaticae，Baplitetea tripartitae和Chenopodieea。在进行植物社会学实地调查的同时，进行植物群丛调查，对景观和土地利用进行分类。从92个sigmassociation的资料中，通过表格工作划分出24个景观单元。这些布局是由海岸到内陆、由低到高的线相对应的，因此地形要素处于同一条线上，即盐沼-海岸-池塘和湖泊-河床-低地-高原-山地。中国科学家赴日考察，目的是与日本西部植被进行比较。阐明了两国万年青林不仅在物种组合上，而且在结构和动态上都具有互作性。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
