通过对青海湖北部沙柳河镇不同植被类型土壤入渗实验测定,研究了不同植被类型土壤入渗特征及土壤蓄水性。结果表明,青海湖农场四大队厚土层低草地、高草地、油菜地和沙柳河镇南薄土层低草地的初渗率均值分别为4.55、4.71、0.64和2.31 mm/min,稳定前平均入渗率均值分别为2.09 mm/min、3.29 mm/min、0.53 mm/min和1.95 mm/min,稳渗率均值分别为1.53 mm/min、2.31 mm/min、0.32 mm/min和1.74 mm/min。在同一实验区,不同植被类型的土壤入渗率为高草地>低草地>油菜地。同种植被厚土层的初渗率大于薄土层,而厚土层的稳定前平均...

Through the determination of soil infiltration experiments on different vegetation types in southern Shaliuhe Town of Qinghai Lake area, the characteristics of the soil infiltration and the water maintenance in soil of different vegetation types were analyzed. The result showed that the mean values of initial infiltration rate of low grasslands, high grasslands and rape fields of thick soil in the fourth group of Qinghai Lake Farm and low grasslands of thin soil in southern Shaliuhe town were separate 455, 471, 064 and 231 mm/min. Average infiltration before stability were 209, 329, 053 and 195 mm/min respectively. The steady soil infiltration was 153, 231, 032 and 174 mm/min separately. In the same land, soil infiltration of high grasslands was highest. The soil infiltration of rape fields was lowest. The soil infiltration of low grasslands was intermediate. The time at which soil infiltration comes to a steady state was different among different vegetation types and soil thickness. Horton formula was a better one for fitting the experimental data, and the applicability of Koctakob formula and general empirical formula was bad in the study area. Soil porosity and the porosity among soil particle of southern Qinghai Lake were bigger than Shaanxi Loess Plateau’s, which led to that steady soil infiltration of southern Qinghai Lake was higher that of Shaanxi Loess Plateau. The characteristics of small soil thickness, low capacity of soil reservoir and little storage capacity in the study area determined the fragile ecological environment and grassland degradation easily occurred in drought years.
