摘　　要：文章采用WetSpass模型评价松嫩盆地的降水入渗补给量。结果得出:①该地区的降水入渗补给量、蒸发蒸腾量和区内产流量,都与土壤质地和土地利用、覆被类型有空间相关性;②从湿润区—半湿润区—半干旱区,降水入渗补给量由大到小;③该区域入渗补给能力从大到小,依次是砂土、砂壤土、粉砂土、粉砂壤土和砂质粘土。The paper evaluates the precipitation infiltration replenishment of Songnen basin by using the WetSpass model.The results show that:①there are very distinct spatial correlation between rainfall infiltration re-plenishment,evapotranspiration and local runoff yield and soil texture,land use and vegetation cover.②the pre-cipitation infiltration replenishment is decreases gradually while the climate changes from humid,semi-humid to semi-arid zones.③the regional infiltration ability is descending in this order:sand,sandy loam,silt sand,silt loam and sandy clay.
