以浙江省红壤小流域生态系统为研究对象，从资源持续开发利用角度首次提出了由小流域地形地貌类型、水资源条件类型及土地资源状况类型组成的红壤小流域生态系统的三级分类体系；明确了浙江省红壤小流域生态系统主要有８ 种类型，其中以低丘岗地地形地貌、缺水或引水灌溉、土地资源较丰富这一类型为主⒚ Taking the red soil small watershed ecosystems in Zhejiang Province as the research object, this paper for the first time proposes the three-level classification system of the red soil small watershed ecosystems composed of the landform types, the water resource conditions types and the land resource status types from the perspective of sustainable development and utilization of resources. It is clear that there are 8 types of ecosystem of red soil small watershed in Zhejiang Province.
