河南植被水平地带性的分布规律

THE HORIZONTAL ZONATION DISTRIBUTION OF VEGETATION IN HENAN

  • 摘要: 河南植被纬向性分布与气温有关。北部属温带落叶林区域,典型植被,山地为落叶阔叶林和常绿针叶林,东部平原的农作物为一年两作或两年三作。南部为亚热带常绿阔叶林区域的常绿、落叶阔叶混交林地带,典型植被为含有常绿成分的落叶阔叶林,针叶林由马尾松、黄山松和杉木林组成。河南植被的经向性分布职决于干燥度引起的地带性变化,东部大别山的植被由黄山松林和茶园来表征,南部的桐柏山地带则没有黄山松林和茶园。

     

    Abstract: Henan is located in the eastern part of China, lies 31°23′—36°22′NL,110°21′—116°39′EL.It is about 167074 km2 in area. The topography consists of plains, hills and mountains. The eastern part is the southern part of Huabei plains. The western part is mainly mountainous region which range from 1000m to 2000m above sea level.In summer, the climate of Henan is controlled by the summer monsoons coming from the Pacific Ocean. But in winter it is influenced by the cold air coming from Siberia. The vegetation of Henan hasa law of geographical distribution from north to south closely related to climate. The types of vegetation are different in different latitudinal zonations.The vegetation in the northern part belong to the temperate deciduous broadleaf forest region. The representative vegetations are the deciduous broadleaf forest and the evergreen needleleaf forest in the mountainous region. For example, Quercus variabulis forest,Quercus aliena var.acutiserrata forest and Pinus tabulaeformis forest, Pinus bugenana forest, etc. On the plains of eastern part, winter wheat, maize and rice are planted two crops a year, or winter wheat, cotton, maize, sesame and sweetpotato are planted three crops in two years. on the sandland, winter wheat, sweetpotato, peanut and sesame are planted oncea year. The mixed evergreen broadleaf forest and deciduous broadleaf forest which belongs to the subtropical evergreen broadleaf forest region cover the southern part of Henan. The representative vegetations are Quereus variabulis,Quercus aliena var.acutserrata and a few evergreen broadleaf trees, for example, Cyclobalanopsis glanca, Chclobanopsis myrsinaefolis, etc. The evergreen needleleaf forest consists of Pinus massoniana, Pinus taiwanensis (higher than 700m above sea level)and Cunnunghamia lanceolata etc.The climate in the eastern part of Henan is moister than that in the western part. In eastern part, the vegetation on the Dabie Mountain is characterized by Pinus taiwanensis and tea plantations. In the western part, however, there are no Pinus taiwanensis forest and tea plantations in Tongbai Mountain region.
