淮河下游地区景观生态特征研究

本文在对淮河下游地区气候，地貌，土壤，植被等景观生态要素研究的基础上，以地貌和基质为基本线索，以植被为标志建立了淮河下游地区的景观生态分类系统。该系统为二级分类系统，包括１０个景观型，３５个景观亚型，其中，景观根据植被（植被型或革培植被型）划分，景观亚型根据地貌，植被（群系组成载培组合）划分。以景观亚型或景观亚型的组合为基本制图单位，以１：１００万土壤图为基础底图，参考多种比例尺的卫星照片，植被图

A Study on the Characteristics of Landscape Ecology in the Lower Huaihe Valley

Based on the studies of climatic, geomorphological, soil and vegetational elements of the tower Huaihe Valley, the landscape ecological classification system for this area is established. It has two grades, including 10 landscape types and 35 landscape subtypes. Landscape type is divided according to vegetation type or cultivated vegetation type, and landscape subtype is classified according to topography and vegetation formation group or cultivated vegetation group. Map of landscape ecological types of the lower huaihe valley (1: 1000000) is compiled.On the map the areas of landscape types and landscape subtypes are measured. Lastly, the ecological problems of the 7 main landscape types (e. g. Spares vegetation Landscape, Evergreen coniferous forest Landscape, Deciduous broad - leaved forest Landscape, Crop on dry land Lsndscape, Rotation of paddy and dry land Landscape, Crop on paddy land Landscape, Lake Landscape) in the Lower Huaihe Valley are analysed in detail, and the corresponding management strategies are put forward.
