摘要
为恢复官厅水库库区植被提供科学依据 ,在官厅库区妫水河流域内延庆县大榆树镇上辛庄小流域试验区 ,进行了不同植被覆盖条件下的土壤积水入渗试验 ,并用 4种入渗公式进行了拟合。通过分析比较 ,得出了不同植被覆盖条件下的土壤入渗规律 ,并对采用考斯恰可夫、Horton、通用经验公式以及Philip入渗模型时的适用性和准确性进行了评价。
In order to provide scientific basis for vegetation rehabilitation in basin area of Guanting Reservoir, in Shangxinzhuang small watershed, which is located on the Dayushu town in Yanqing county in Guishuihe river basin of Guanting Reservoir, the soil pounding infiltration experiments in different vegetation coverages were done and the experimental data were simulated by four infilitration models. Through analyzing and comparing, the law of soil infiltration in different vegetation coverage was found, the applicability and veracity using Костякоь, Horton, General Experimental formula and Philip model were evaluated.
