A soil survey was conducted on Qinghuahai National Wetland Park by using traditional soil profile survey combined with typical route survey methods.The results showed that four types of soil namely red soil,paddy soil,alluvial soil and swamp soil were identified.The distribution,soil profile configuration and characteristics,basic physical and chemical properties of the soil types were described.The largest distribution area was the red soil under the Pinus yunnanensis forest or the pine-oak mixed forest in the catchment area and the hydromorphic paddy soil in the dam area.Most of the soil layers were deep,with complete profiles,typical diagnostic layers,good soil ecosystems and good soil fertility.This paper proposed appropriate transformation of existing low-quality and inefficient forest stands,focusing on the protection and rational use of paddy soil,and further conducting regional investigation and research on swamp soil and sediment.
