摘要
在对江苏北部气候、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该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、３１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，编制了江苏北部１∶１００万景观生态类型图。详细分析了江苏北部稀疏植被景观、常绿针叶林景观、落叶阔叶林景观、旱地作物景观、水旱轮作景观、水田作物景观、淡水水生植被景观等主要景观型的生态问题，提出了相应的生态对策。
Based upon the studies on climate, geomorphology, soil and vegetation, the landscape ecological classification system for the northern part of Jiangsu Province is established. It is a two grades system, including 10 landscape types and 31 landscape subtypes. Landscape type is divided by vegetation and landscape subtype is classified according to topography and vegetation map of landscape ecological types of the northern part of Jiangsu Province (1∶1000000) has been drawn. On the map the areas of landscape types and landscape subtypes are measured. Lastly, the ecological issues of the main landscape types in the northern part of Jiangsu Province such as sparse vegetation landscape, evergreen coniferous forest landscape, deciduous broad leaved forest landscape, dry land crop landscape, rotation of paddy and dry land landscape, paddy land crop landscape, freshwater landscape are analysed in detail, and the corresponding strategies are put forward.
