صينى. 根据北京市红门川流域原有1：101300土地利用图，结合流域1990年、1995年、2000年和2005年四期遥感影像，在GIS支持下，得到四期土地利用图，采用AreView分析获得空间数据和属性数据。将不同年份土地利用结构中的水源涵养林替换为单一森林类型，利用SWAT模型模拟单一森林类型下的产流量。结果表明：红门川流域不同森林类型产流有所不同，其排序为：灌木林〉针叶林〉混交林〉阔叶林。森林植被调蓄径流功能与降水有一定关系，在丰水年和汛期不同森林类型产流差异明显，在枯水年和枯水期差异不明显。

Based oil the land - use map （1：10000） and the remote sensing images （ 1990,1995,2000 and 2005 ） of Hongmenchuan watershed of Beijing, the spatial and attribute data of these 4 periods were obtained using ArcView software. Simulate runoff using SWAT model of the substitution of water conservation forest and single forest type under the land use structure in different year. The re- suits showed that： The runoff of different forest types was different, the order is： shrubbery 〉 coniferous forest 〉 mixed forest 〉 broad - leaved forest. The function of storing runoff of forest vegetation is different, difference of different forest type is observed in wet year and flood season, difference of difference of different forest type is not observed in low flow year and low water season.
