在分析南亚热带丘陵赤红壤降雨入渗和产流过程基础上,依据田间实测资料,建立了丘陵赤红壤降雨入渗产流数学模型,分析了南亚热带丘陵赤红壤地表径流的动态变化特征及其影响因素。结果表明,丘陵赤红壤区,4~9月每次降雨产生的径流量变化范围为0.2~51.04mm,径流率变化范围为0.56%~47.58%,10月至次年3月一般不产生地表径流;地表径流量与降雨量拟合关系式为R0=0.0259.Pn1.4034,径流率与土壤表层初始含水量拟合关系式为R′0=9.8788W7.7702,而降雨强度对径流量的影响要比降雨量、土壤表层初始含水量小得多。
在分析南亞熱帶丘陵赤紅壤降雨入滲和產流過程基礎上,依據田間實測資料,建立瞭丘陵赤紅壤降雨入滲產流數學模型,分析瞭南亞熱帶丘陵赤紅壤地錶徑流的動態變化特徵及其影響因素。結果錶明,丘陵赤紅壤區,4~9月每次降雨產生的徑流量變化範圍為0.2~51.04mm,徑流率變化範圍為0.56%~47.58%,10月至次年3月一般不產生地錶徑流;地錶徑流量與降雨量擬閤關繫式為R0=0.0259.Pn1.4034,徑流率與土壤錶層初始含水量擬閤關繫式為R′0=9.8788W7.7702,而降雨彊度對徑流量的影響要比降雨量、土壤錶層初始含水量小得多。

Based on the analyses about the characteristics ofrainfall-infiltrati on-runoff of latored soil in hills of subtropics areas of south China,and on field measurement data,the mathematical model of rainfall-infiltration-runof f of latored soil in hills was made,and the dynamic characteristic of runoff an d its influencing factors of latored soil in hills of subtropics areas of south china. The results showed,in latored soil area in hills,in April to September ,the any runoff amount changed in the range of 0.2~51.04 mm,the any runoff ra te changed in the range of 0.56%~47.58%. There was no runoff amount in Octo be r to Mach of next year. The relationship between the runoff amount and rainfall amount was:R0=0.0259.Pn1.4034,and the relationship between the runoff rate and initial soil water content in surface layer was:R′0=9.87 88W7.7702.
