摘要/Abstract

摘要： 基于VIC(Variable Infiltration Capacity)大尺度水文模型,采用实测的日降水和日最高、最低气温数据,模拟了近35年(1971~2005)全国范围30 km×30 km分辨率的逐日土壤含水量。文章利用43个流域的实测流量资料,率定模型水文参数,建立和验证水文参数移用公式,确定无资料地区的水文参数。选取全国范围内的28个站19年的土壤含水量实测值,对模拟的土壤含水量进行了验证。结果表明,VIC模型较好地模拟了土壤含水量,尤其是在湿润和半湿润地区。模拟的0~100 cm的土壤含水量多年平均值与实际的全国土壤水分分布较为一致。

Abstract: On the basis of Variable Infiltration Capacity(VIC) land surface macroscale hydrology model and observed maximum and minimum air temperature and precipitation this paper simulated daily soil moisture values over China for the period January 1,1971 to October 31,2005.The model was applied over a grid of 10,458 points with a resolution of 30 km?30 km.The model was first calibrated and validated by using observed hydrographs over 43 catchments.In situ soil moisture measurements from 28 sites over the country were also used for model validation.VIC performs well over both calibration and validation catchments especially in humid and semi-humid regions.The 35-yr soil moisture climatology for the 0-100m from VIC is consistent with known soil moisture conditions in China.
