1鹰潭小流域季节性降雨径流特征研究显示文摘降雨是影响低丘红壤坡地土壤侵蚀和养分随径流迁移的一个关键因子。利用三角量水堰自动测量径流量和自动雨量计观测数据,分析了鹰潭小流域的季节性降雨径流特征。小流域降雨主要发生在4~6月,总量达512.4mm,占观测时段总雨量的70.1%,而旱季7~9月仅为218.9mm。上游、下游围堰累积径流量随旱季、雨季的变化表明:小流域降雨-径流-土壤水界面水分转化可分为土壤水补给阶段(4月14日~6月14日)、土壤水饱和阶段(6月15日~7月28日)和土壤水消耗阶段(7月28日以后)。雨季径流量对降雨的响应波动超过旱季。日累积降雨量与日累积径流量有极显著的正相关关系。径流小区水样分析结果说明观测期下坡径流小区总氮(TN)、总磷(TP)浓度高于上坡。景元书 张斌 王明珠 Thimm A Zepp H 2003水土保持学报2003,17,5:11
2桔园地土壤水分与径流的坡位差异研究显示文摘从大气降水-土壤水循环系统出发,于2001~2002年在江西省余江县刘垦农场内桔园地用定位法对土壤水分与径流的坡位差异进行了研究。结果表明,由于上坡、下坡土壤的质地分异,雨季上坡水势值总体上高于下坡,而旱季上坡水势值基本上低于下坡,相对应的土壤水分150cm贮水量及收支平衡也有明显的差异;用径流小区法测定的径流表明,旱季10mm降雨上坡、下坡径流深度为0.596,0.585mm,但雨季上坡、下坡10mm降雨径流深度为0.429,0.488mm。为土壤水分适时调控、节水定量灌溉及分析养分迁移提供依据。景元书 张斌 王明珠 Thimm A Zepp H 2004水土保持学报2004,18,2:8

7低丘红壤深层水分的CASCADE模型应用与管理显示文摘低丘红壤深层水分对建立合理的耕作制度和旱季作物水分调控有重要意义。花生地定位试验实测数据表明:旱地土壤水分垂直梯度变化趋势基本表现为增长型,土壤含水量受降雨影响在40cm土层旱季明显大于雨季。采用CASCADE模型模拟了不同年型低丘红壤地区花生地土壤含水量的动态过程,各层次模拟值与实测值的平均绝对偏差<4 7%,模型可用于分析红壤水分的季节性变化规律和采取抗旱措施。还针对水分利用存在的问题,从工程措施、生物措施和生产措施三方面进行红壤旱地水分资源的有效管理,提高红壤地区降水资源与深层水分的利用率。景元书 张斌 赵其国 Zepp H Thimm A 2003山地学报2003,21,4:1
