山东南部景观生态特征研究

以地貌和基质为基本线索，以植被为标志，建立了山东南部的景观生态分类系统。该系统为二级分类系统，包括７个景观型、１７个景观亚型。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、土地利用图、地貌图等，编制了山东南部１：１００万景观生态类型图；在景观生态类型图上量算了各景观亚型的面积，并且分析了山东南部主要景观型的生态问题，据此提出了相应的生态对策。

A STUDY ON THE ECOLOGICAL CHARACTERISTICS OF LANDSCAPE IN THE SOUTHERN PART OF SHANDONG PROVINCE

Based on the studies on climate, geomorphology, soil and vegetation, the landscape ecological classification system for the southern part of Shandong Province is established. It consists of two grades, including 7 landscape types and 17 landscape subtypes. Landscape type is divided by vegetation (vegetation type or cultivated vegetation type), and landscape subtype is classified according to topography and vegetation (formation group or cultivated vegetation group). Making landscape subtype be mapping unit, letting the Soil Map (1:1000000) of the Region be the base map, and consulting several kinds of maps relating to the area (e.g. landsat images, vegetation maps, landuse maps, geomorphological maps), Map of Landscape Ecological Types of the Southern Part of Shandong Province (1:1000000) is compiled. On the map the areas of landscape types and Landscape subtypes are measured. Lastly, the ecological problems of the main landscape types in the southern part of Shandong Province (e.g. sparse vegetation landscape, evergreen coniferous forest landscape, deciduous broad leaved forest landscape, crop on dry land lsndscape, rotation of paddy and dry land landscape, lake landscape) are analysed in detail, and the corresponding strategies are put forward.
