中文摘要：

为研究网格式生物埂护坡的时间效应，以无生物埂护坡的裸坡为对照，对建设时间为1～4年的黄花生物埂坡面土壤的入渗与贮水特征进行了研究。结果表明，①建设年限1～4年的黄花生物埂与裸坡的饱和贮水量、最大涮留贮水量、最大吸持贮水量、初始入渗率、稳渗率、平均渗透率和渗透总量均表现为：4年〉3年〉2年〉1年〉裸坡，到均与建设时间呈显著的线性关系；②坡位对土壤贮水及渗透性的影响明显。1～4年的黄花生物埂均表现为坡上〉坡中〉坡下的规律，而裸坡表现出与之相反的规律；③土壤渗透性与土壤理化性质（总孔隙度、非毛管孔隙、毛管孔隙、土壤密度及有机质）和植被因子（根长密度、地下生物量和地上生物量）显著或极显著相关。

英文摘要：

To study the time effect of net form banks on slope protection, soil water holding capacities and infiltration characteristics of Hemerocallis fulva banks were studied in one-year to four-year development period, and non-banks bare slop was used as a control . The results indicated that： @Soil saturated water storage, water-holding capacity of non-capillary porosity, water-holding of capacity porosity, initial infiltration rate, average infiltration rate, stable infiltration rate and accumulate infiltration were all shown as the sequence of 4a〉3a〉2a〉1a〉bare slop, which had a linear function with development time. （2）The influence of slope position on the infiltration rate had obvious regularity with upslope〉middle slope〉down slope in one-year to four-year development period; however,, there existed a contrary tendency for bare slop. （3）@The closely relative factors to soil water infiltration properties were picked out, which included total porosity, non-capillary porosity, capillary porosity, soil hulk density, the organic matter content, root length density, underground biomass and above-ground biomass.
