海南岛东南海岸带植被景观分类系统探讨

将Forman和Godron提出的基于植被(或土地利用)的景观分类方法与中国特有的土地类型分类方法相结合,采用区域性原则,综合性与主导因素相结合原则,人类干扰原则与层次性原则等分类原则,确立研究区海岸带植被景观类型系统。根据景观土地属性分类的植被分类途径,将海南岛东南海岸带景观分为植被景观、农田景观、湿地景观、建筑景观与其他景观等5种一级景观类型;针叶林、阔叶林、人工林、灌草丛和红树林等5种二级植被景观类型;青梅Vitica mangachapoi-柄果木Mischocarpus sundaicus林、榕树Ficus microcarpa-桄榔Arenga pinnata林等39种植被斑块类型(三级景观类型)。表2参13

Classification system of vegetation landscape in south-east coastal zone,Hainan Island

The classification system of coastal zone vegetation landscape was established being drawn lessons from land type classification in China and Forman and Godron's landscape classification based on vegetation or land usage in the light of the principals,such as the regional one,comprehension and main factor one,human disturb one and administrative level one.According to land usage types and the physiognomy of the vegetation communities,five 1st level landscape types,i.e.vegetation landscape,farmland landscape,wetland landscape,buildings landscape and other landscapes,and five 2nd level vegetation landscape types,i.e.evergreen coniferous forest,broad-leaved forest,human-planting forest,mangrove and scrub and herbosa were classified by using vegetation approach of land attribute classification in landscape ecology,then on basis of the upper layer tree's life form of vegetation landscape,and 39 3rd level vegetation landscape types,such as Vatica mangachapoi-Mischocarpus sundaicusi forest and Ficus microcarpa-Arenga pinnata forest were divided.
