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
3Methodological Framework for a Multi-Scale Study on Hydrological Processes and Soil Erosion in Subtropical Southeast China显示文摘This paper introduces and illustrates the concepts of geoecological process combinations and geographical or landscape dimensions by outlining the methodology of a Sino-German cooperative project in Southeast China and presents the first results of the modelling process for the catchment scale. The project equipped a catchment in subtropical Southeast China from plot scale to catchment scale in order to study the hydrological and soil erosion processes. Distinct spatial differences in principal water and soil material fluxes were quantified. Deep drainage peaks occurred in May, June and July and even in August and November. Measurements in erosion plots as well as sedimentary deposits revealed that there was soil erosion connected with overland flow. Consistent with the results from the regular catenary variations of soil colors, textural stratification and hydrograph analysis, there was also a clear indication of interflow from measured soil moisture data. The experimental set up has the potential to further deepen the understanding of small-scale processes involved in lateral water fluxes and soil erosion. The expected results and interpretations will lead to a further integration of the collected data. In the future, to understand matter transfer in and between landscape ecological units, agricultural influence on nutrient status and flux data will be incorporated.H.

4低丘红壤区小流域土壤肥力性质空间分布特征显示文摘利用GIS软件的空间分析功能,以土地利用类型区为分析单元,分析评价了亚热带典型小流域土壤肥力性质的空间和剖面分布特征。研究结果表明:小流域土壤酸化明显,旱地酸度高于水田;土壤保肥力处于中等水平以上;42.6%的土壤表层有机质处于中度缺乏状态;94.3%的表层土壤全P和97.3%的土壤全K处于中度缺乏状态。不同土地利用方式下土壤性质分异明显,综合评价结果表明水田肥力高于旱地。唐家良 张斌 王明珠 Alexander Thimm Harald Zepp 2006土壤2006,38,4:8
5Anisotropy of Soil Hydraulic Properties Along Arable Slopes显示文摘The spatial variations of the soil hydraulic properties were mainly considered in vertical direction.The objectives of this study were to measure water-retention curves,θ(ψ),and unsaturated hydraulic conductivity functions,K(ψ),of the soils sampled at different slope positions in three directions,namely,in vertical direction,along the slope and along the contour,and to determine the effects of sampling direction and slope position of two soil catenas.At the upper slope positions,the surface soils(0-10 cm) sampled in the vertical direction had a lower soil water content,θ,at a certain soil water potential(-1500 kPa < ψ <-10 kPa) and had the greatest unsaturated hydraulic conductivity,K,at ψ > -10 kPa.At the lower slope positions,K at ψ > -10 kPa was smaller in the vertical direction than in the direction along the slope.The deep soils(100-110 cm) had similar soil hydraulic properties in all the three directions.The anisotropic variations of the hydraulic properties of the surface soils were ascribed to the effects of natural wetting and drying cycles on the structural heterogeneity.These results suggested that the anisotropy of soil hydraulic properties might be significant in inffuencing soil water movement along the slope and need to be considered in modeling.JING Yuan-Shu ZHANG Bin A.

6利用水同位素和水文地球化学证据表征张家口地区的地下水年龄和补给率显示文摘Despite the increasing depletion of the groundwater at the Zhangjiakou aquifer system in the northwest of Beijing-Tianjin-Hebei region,little information is available on the hydrological process of groundwater in this region.In this study,we utilized water isotopes composition(51sO,5D and 3H)of groundwater,river and precipitation to identify the characteristics of hydrochemistry,groundwater age and recharge rates in different watersheds of the Zhangjiakou area.Results showed that the river water and groundwater could be characterized as HCO3-Mg Na,HCO3 CI-Na and HCO3-Mg Na,HCO3 CI-Na,HCO3 CI-Na Mg types,respectively.The 5D and 5180 values in precipitation were linearly correlated,which is similar to the Global Meteorological Water Line(GMWL).Furthermore,the decreasing values of the 6D and 5180 from precipitation to surface water and groundwater indicate that groundwater is mainly recharged by atmospheric precipitation.In addition,the variation of 3H concentration with depth suggests that groundwater shallower than around 100 m is generally modern water.In contrast,groundwater deeper around 100 m is a mixture of modern and old waters,which has longer residence times.Groundwater showed a relatively low tritium concentration in the confined aquifers,indicating the groundwater recharged might be relatively old groundwater of over 60 years.The flow velocity of the groundwater in the study area varied from 1.10 to 2.26 m/a,and the recharge rates ranged from 0.034 to 0.203 m/a.The obtained findings provide important insights into understanding the groundwater recharge sources and hydrochemistry in the Zhangjiakou area,in turn developing a sustainable groundwater management plan.张清华 罗专溪 陆文 HARALD Zepp 赵玉峰 唐家良 2020Journal of Geographical Sciences2020,30,6:2
