摘要
针对AnnAGNPS模型在国内推广应用中因相关数据缺失,数据库建立困难的现状,以三峡库区香溪河流域为研究示范区,探讨在现有资料的基础上如何建立AnnAGNPS模型中土壤和气象这2类重要数据库,重点研究数据库建立过程中露点温度、太阳辐射、土壤质地转换、水文土壤组划分、土壤侵蚀因子K等重要参数的计算方法。以期为An-nAGNPS模型数据库的建立研究提供借鉴,并为模型在国内的推广应用提供参考。
Due to a lack of relevant data and database construction difficulties of AnnAGNPS model in the domestic promotion at present, Xiangxi River watershed in the Three Gorges Reservoir Region is selected as a case study area in this paper. Suitable An nAGNPS model climate and soil databases are established on the basis of existing data,and importance is attached to introducing the parameter＇s construction process in detail, including dew point temperature, solar radiation, soil texture conversion, hydrological soil groups and soil erosion factor K, etc. in order to provide a reference for a similar model database construction process,and promote its use in our country.
