| 摘 要： | 黑河上游山区土壤水分表现为非饱和特征,准确估算该区域表层土壤非饱和导水率(K10)可提高山区生态水文模型的可靠性.本研究野外测定了黑河上游排露沟流域的K10,并利用土壤传递函数(PTFs)以土壤机械组成、容重及土壤平均粒径作为分析因子进行模拟估算,结果表明:排露沟流域森林、草地、退耕裸地的K10均值分别为(0.21±0...

| Abstract: | In mountain region of upper Heihe River,the characteristic of soil water regime is of unsaturated,and thus,to accurately estimate the values of its topsoil unsaturated hydraulic conductivity (K10) is essential for eco-hydrological modeling. Taking the Pailugou catchment in upper Heihe River as a case,its topsoil K10 values were measured,and simulated by the pedotransfer functions (PTFs) integrating with factors-soil mechanical composition,bulk density,and average particle size. The observed K10 in forestlan... |
