土壤及土壤膠質物ノ理學的性質ニ就テ

, 1938
　　土壤膠質物是存在於土壤中特別的物質，極為細微，具理學成分。膠質此一學術語與晶質有所區別，其亦非食鹽、砂糖等諸溶液的結晶。膠質在土壤中是以物質的形式微量存在的。土壤膠質物的理學性質其一為吸水後的發熱膨脹，更進一步的探討會發現其與水量與土中膠質物之多寡有關，化學性質方面則與土壤中酶基置換作用有關。土壤膠質物與土壤組織結構有很大的影響，對土壤排水、通氣性、可塑性、黏著力諸程度上有相對的影響存在。此外，土壤膠質物亦會影響植物對土壤養分的吸收。 　　先行研究指出，土壤膠質物的形成與土壤中動植物遺骸及腐植植 ...

丘陵赤红壤降雨入渗产流模型及其变化特征

Shuitu Baochi Xuebao, 2001
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～ 5 1.0 4m m,径流率变化范围为 0 .5 6 %～ 47.5 8% ,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 .0 2 5 9.Pn1 .40 34 ,径流率与土壤表层初始含水量拟合关系式为 R′0 ...
