华北石质山区坡地产流模型

坡地是流域的基本产流单元。对坡地产流模型的研究,可为研究流域的水文过程奠定基础。本文在认识坡地产流规律的基础上,经过对人工模拟降雨试验中取得的产流各个环节(降雨、出流及土壤含水量变化)的数据的分析,建立了一个具有物理机制的简单的坡面产流模型。其中,使用Horton模型模拟入渗和地表产流过程,用水箱模型模拟壤中流过程。模型能够同时对降雨过程中的地表、地下出流和土壤含水量变化过程进行模拟。计算得到的产流总量的误差较小,但在变化过程线上存在一些差异。这些差异主要是由模型对实际情况的简化和假定、数学模拟的局限性、变雨强降雨过程的复杂性等因素引起的。这种分层组合的坡面产流模型对华北石质山区的上层超渗、下层蓄满的产流特征是可行的。本文所做的工作是对华北石质山区分布式水文模型的产流模块的初步尝试。     

不同雨强对杉木和米槠林地表径流和可溶性有机碳的影响

采用径流小区法,对中亚热带地区的杉木人工林和米槠次生林在不同雨强下径流量和可溶性有机碳（DOC）流失浓度进行比较研究。结果表明：在小雨、中雨、大雨和暴雨4场降雨过程中,米槠次生林和杉木人工林的地表径流量和DOC流失浓度变化趋势一致,即降雨强度增加,地表径流量也随之增加。DOC浓度均呈现了随着雨强的增加而逐渐降低的趋势。说明降雨强度对径流量和DOC浓度均产生了较为明显的影响;米槠次生林和杉木人工林的地表径流量之间差异不显著,米槠次生林和杉木人工林的DOC流失浓度除大雨外均达到显著性水平差异（P〈0.05）,说明植被类型对地表径流量影响较小,对DOC浓度具有较明显的影响。     

北京密云水库小流域非点源污染负荷估算

根据不同类型的非点源污染发生区,选择若干径流小区,进行降雨、径流量、径流水质同步监测,分析不同土地利用类型小区地表径流和泥沙中氮、磷的流失情况。根据地貌特征和土地利用情况,利用通用土壤流失方程和SCS法分别计算不同土地利用类型区土壤侵蚀量和径流量,分析氮、磷的流失特点。结果表明:坡耕地和荒草坡单位面积土壤流失量比较严重;村庄中溶解态氮的流失量最多;村庄和坡耕地是氮、磷流失的重点区域。

粤北石漠化灌丛坡地模拟降雨地表径流水中钙离子含量变化

通过模拟降雨试验,研究粤北地区不同石漠化程度的灌丛坡地地表径流水中钙离子含量的变化。结果表明,在不同雨强下,不同石漠化灌丛坡地地表径流量、地表径流水钙离子浓度和地表径流水钙离子总量随石漠化程度的加重呈逐渐上升后又降低的倒“U”型趋势;在同一雨强下,潜在、轻度和极重度石漠化坡地径流水钙离子流失量远低于中度和重度石漠化坡地;地表水中的钙离子流失总量和地表径流量、土层厚度、岩石裸露率均有较高的相关性,其中与地表径流量达到显著性相关。     

北京地区径流曲线数模型中的径流曲线数

径流曲线数模型(SCS-CN模型)是国内外最受欢迎的地表径流评价方法,该模型只需综合参数--径流曲线数(CN),该参数反映降雨前流域的地表和土壤特征。本文的目的是确定北京地区径流曲线数模型中的径流曲线数。研究采用了北京密云、延庆、门头沟64个坡面径流小区的降雨径流资料,用算术平均值法计算出小区径流曲线数值,用定水头法测定了北京主要土壤类型和土地利用类型的饱和导水率,用经验公式确定出64个坡面径流小区的饱和导水率值,并根据饱和导水率确定了北京地区和坡面径流小区的水文土壤组类型,得到了北京不同水文土壤组、土地利用下的径流曲线数数据库。结果表明:北京地区主要水文土壤组为B类;土地利用、水土保持措施、植被盖度和前期土壤湿度等对径流曲线数有显著影响;根据北京径流小区径流资料得到的径流曲线数值比美国土壤保持局查算表提供的数值要大。本研究结果可为该区域的地表水资源量评价以及土地利用管理提供服务。     

紫色土坡面降雨侵蚀试验研究

坡面水蚀的主要侵蚀动力来自降雨及其产生的地表径流,将坡面水蚀过程分为降雨侵蚀和径流侵蚀,可以从侵蚀动力、侵蚀特征差异与侵蚀规律等方面研究坡面水蚀过程与机理。应用人工模拟降雨及微小区测定技术,以大田紫色土为研究对象,模拟和测定不同雨强与不同坡度条件下降雨侵蚀过程和侵蚀量,揭示以降雨为主要动力的土壤降雨侵蚀特征和规律。研究结果表明：(1)小雨强(＜67．26 mm/h)下,紫色土坡面降雨侵蚀率具有稳定性,随着降雨历时的增加变化微小；大雨强(106．57 mm/h)下,降雨侵蚀率随降雨历时增加呈上下波动；(2)紫色土降雨侵蚀率与降雨强度呈线性相关,随降雨强度增加而直线增加；(3)降雨侵蚀率与坡度符合二次抛物线关系,随坡度的增加出现临界坡度,且临界坡度随雨强的变化而改变。在中小雨强(18．06～67．26 mm/h)条件下,临界坡度SK的变化范围在17°～19°。在大雨强条件下,临界坡度有逐渐增大的趋势；(4)当坡度与雨强共同影响产沙效应时,坡度对降雨侵蚀的影响较小,雨强能掩盖坡度对产沙的贡献。     

东北黑土区坡耕地土壤侵蚀对影响因素响应的定量分析

东北黑土区坡地耕作方式多样,侵蚀过程复杂,形成了强烈的水土流失,须加强土壤侵蚀影响因子对产流产沙影响的定量化研究.本文利用2013-2017年东北典型黑土区海伦市光荣小流域不同处理方式的坡耕地径流小区监测数据,采用K均值聚类法和通径分析法,系统研究了不同降雨类型事件中坡耕地产流产沙对影响因素的响应.研究结果发现,研究区以中等历时、中等雨强、中等雨量的降雨(RⅢ)为主,其次是长历时、中等雨量的变雨强类型降雨(RⅡ),长历时、大雨量、大雨强的大暴雨(RⅠ)极少发生.横坡垄作对RⅢ的水土保持防护效益明显优于RⅡ.在免耕、少耕、顺坡垄作和裸坡小区,RⅡ和RⅢ的平均次降雨径流深相差较小,但RⅢ的土壤流失量明显高于RⅡ,RⅢ是研究区土壤流失的主要贡献者.降雨量和降雨侵蚀力分别在RⅢ和RⅡ中对产流具有较大影响.水土保持措施通过直接和间接影响径流深的作用进而控制土壤流失量.作物经营管理对土壤流失量的影响以间接效应为主.本文研究结果表明不同处理小区的径流深和土壤流失量均具有显著差异,实施水土保持措施能明显减少产流产沙.单纯从防治水土流失的角度考虑,横坡垄作是该区最为适宜的水土保持措施,其次是免耕,不推荐少耕措施.     

粤北石漠化地区水文过程试验研究

通过在粤北石漠化地区选取不同石漠化阶段样地,进行人工降雨模拟试验,研究粤北石漠化地区水文过程。结果表明:随石漠化程度的加深,地表植物对雨水最大截留量不断下降,其中以重度→极重度阶段降幅最大,达6倍多。土壤持水量在重度→极重度石漠化阶段发生转折。地表径流在中度和重度石漠化土地上具有相同特征,但在与轻度和极重度石漠化土地中差异明显。当雨强为30~50 mm/h时,产流35 min内总径流量以中度石漠化样地最高;当雨强为51~60 mm/h时,以极重度石漠化样地最高;而当雨强为61~70 mm/h时,则以重度石漠化样地最高。在各石漠化阶段样地上以雨强35 mm/h进行人工模拟降雨60 min,有0.6%~2.71%雨水被植被及枯落物截留;2%~53.31%雨水被土壤吸收;2.18%~7.37%雨水转化为地表径流;41.8%~93.41%雨水渗漏形成地下水。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
