摘要
文章以三峡库区典型小流域——陈家沟小流域为研究对象,构建了陈家沟小流域SWAT模型空间数据库和属性数据库。通过对地形图数字化处理、土地利用方式重新编码及土壤类型自定义化细分,构建了空间数据库。通过查阅《万县地区土种志》,运用软件和经验公式,利用实测和调查数据,构建了属性数据库。陈家沟小流域SWAT模型数据库的构建,为模型在此流域的应用奠定了基础。
A typical small watershed in Sanxia area-Chenjiagou small watershed as the research object, spatialand attribute database were constructed for SWAT model of Chenjiagou small watershed. The spatial databasewas constructed based on the processing the topographic map digitally, re-encoding the land use pattern and sub-dividing the customized soil type. The attribute database was constructed by looking at the‘soil species in Wanx-ian area＇, using software and empirical formula for calculating and using measurement and investigated data.The SWAT model based database construction can be the foundation in application of the model in this water-shed.
