坡长对坡耕地侵蚀产沙过程的影响 总被引：9，自引：0，他引：9
蔡强国 《云南地理环境研究》1998,10(1):34-43
模拟降雨试验结果揭示出随着坡长增加,径流与侵蚀产沙量越大。当坡长小于１５ｍ时,累积侵蚀模数与降雨历时关系明显呈线性,其斜率随坡长增加而渐陡,当坡长大于１５ｍ时,累积侵蚀模数与降雨历时明显是非线性关系;坡长是导致细沟侵蚀的重要因素。细沟发育时,其侵蚀产沙量大约是坡面或细沟间的２－５倍;当细沟趋于稳定时,与无细沟发育的坡面水流含沙量值类似。在４０ｍ坡长小区,其单位时间侵蚀模数与２５ｍ坡长小区无明显差异,水流含沙量并无明显增加,显示出当坡长大于临界坡长时的变化过程规律。利用等高植物篱或等高地梗减少坡长有效值,可以大大降低单位面积上的土壤流失量。 相似文献

黄土坡面细沟水流分离能力 总被引：2，自引：0，他引：2
水流分离能力是土壤侵蚀研究的重点内容之一,阐明细沟水流分离能力变化规律可以深入认识细沟侵蚀过程,为建立细沟侵蚀过程模型奠定重要基础。采用细沟水槽试验方法对黄土坡面细沟水流分离能力进行研究,结果表明:不同流量下,细沟水流分离能力随坡度增加而增大,可用线性方程很好地描述;不同坡度下,细沟水流分离能力随流量的增加而增大,可用幂函数方程很好地描述;细沟水流分离能力因子模型为流量及坡度对细沟水流分离能力影响的二元幂函数方程,方程中流量对细沟水流分离能力的影响大于坡度的影响。 相似文献

黄土坡面发育平稳的细沟流水动力学特性 总被引：3，自引：0，他引：3
由于天然降雨存在间歇性,常会出现前期降雨已经发育成型的细沟又经历了二次降雨的情况,但目前对这一条件下细沟流水动力学特性的研究还很少。本文采用室内人工模拟降雨的方法,通过间隔24 h两场不同雨强的降雨,研究黄土坡面经过第一场降雨形成比较稳定的细沟之后,在第二场较小雨强降雨过程中,细沟发育平稳时的流水动力学特性。研究结果表明:①细沟流速大小受坡长影响并不显著,相同坡度下不同坡长的细沟流平均流速差别不大;细沟流速受细沟形态影响较大,25°坡面比20°坡面细沟密度大,流速相对较小;②剪切力大小受流量和坡度共同作用;雷诺数与水流剪切力呈显著正相关关系,弗洛德数与水流剪切力则呈显著负相关关系;③随着距坡顶距离的增加,阻力系数呈增大趋势;第二次降雨强度相同,坡度大的坡面上阻力系数也较大,可见阻力系数与径流量和坡度的关系十分紧密;阻力系数与雷诺数之间呈显著正相关关系,雷诺数的增加意味着平均流速增大,水流强度增大导致细沟形态更为复杂,水流受到的阻力增大;虽然雷诺数增加同时也意味着水流深度增大,但从试验结果可见,陡坡条件下阻力系数受流速的影响较大。 相似文献

山前洪积扇坡面细沟侵蚀跌坑特征的试验研究 总被引：1，自引：0，他引：1
跌坑的出现是坡面侵蚀过程中的重要现象,标志着细沟侵蚀正在发育,跌坑的贯穿标志着细沟的形成。采用土槽冲刷模型试验,选取流量、坡度、冲刷时间和坡面形态作为影响跌坑发育的因子结合正交试验调查了不同试验条件下跌坑发育特征及影响因素。结果表明：影响跌坑发育的因素主次为冲刷时间、流量、坡面形态、坡度;跌坑沿坡面连续分布,深度具有波动性,沿坡向下呈现先增大后减小的趋势,最大值一般发育在坡面中部;根据跌坑的发育特征将坡面细沟侵蚀划分为片蚀、细沟雏形、细沟发育和细沟调整四个阶段;坡面细沟侵蚀跌坑深宽积与土壤侵蚀量具有较显著线性关系。研究结果对输油管线水毁及水土流失防治具有一定的参考价值。 相似文献

黄土坡面细沟侵蚀过程的REE示踪 总被引：6，自引：0，他引：6
利用REE示踪技术探讨了坡面细沟侵蚀的发育过程。试验结果表明：在细沟发育过程中，各坡段细沟侵蚀量呈动态变化趋势；细沟发育过程可以分为起始、发展、稳定3个阶段，在不同阶段，侵蚀方式、发育特征迥异。总的看来，在坡顶部、上部、中部、下部4个坡段上，细沟发育过程中，坡面下部的侵蚀量较大。但随着放水流量的增加，坡面上部侵蚀量的比重增加。由于溯源侵蚀，最下部坡段的相对侵蚀量从92％减少到37％，呈显著下降趋势，其它3个坡段则分别从4．7％、0．25％、2．14％增加到29％、17％和23％。试验结果还表明，REE示踪法不仅可定量测定不同坡位的侵蚀量，还可以揭示冲刷过程中各坡位相对侵蚀量的变化趋势。 相似文献

细沟侵蚀是黄土高原坡面极其重要的侵蚀过程之一,汇沙对细沟侵蚀强弱具有重要影响,阐明汇沙对细沟侵蚀的影响与贡献,可以揭示坡面细沟侵蚀过程机理,并为治理坡面水土流失提供科学依据.采用定流量人工放水的组合小区模拟降雨的方法,对不同降雨强度与不同坡度下黄土坡面汇沙对细沟侵蚀的影响及贡献进行了研究,结果表明:细沟上方汇沙、细沟间汇沙、细沟径流剪切力对细沟侵蚀的影响,在不同降雨强度、不同坡度、不同降雨强度及坡度下皆可用三元对数方程描述;细沟上方汇沙、细沟间汇沙、细沟径流剪切力,以及细沟上方汇沙与细沟间汇沙及细沟径流剪切力三者的交互作用对细沟侵蚀的贡献率,在不同降雨强度下分别为13.18％、4.98％、61.2％及8.26％,在不同坡度下分别为4.73％、1.19％、73.65％及5.4％,在不同降雨强度及坡度下分别为10.84％、0.44％、65.22％及6.97％. 相似文献

为了明确土壤性质对坡面侵蚀方式作用机制的影响,本研究采用室内模拟降雨试验,选取黄土高原典型暴雨强度,在不同坡度条件下,对两种黄土的坡面侵蚀方式、形态特征、产流产沙过程及其相应径流流速的变化规律进行了研究。结果表明,绥德土径流量明显高于安塞土,10º、15º和20º时前者的平均径流量分别比后者高出51.1%、55.5%和63.0%,且前者更易形成细沟,使得其平均含沙量和平均产沙率分别是后者的1.14~3.59倍和2.50~8.48倍。在片蚀阶段,与绥德土相比,安塞土的含沙量较高,后者的平均含沙量是前者的1.24~1.73倍,但两种土壤的含沙量和产沙规律相同,均表现为先快速增加到最大值,然后逐渐降低到相对稳定状态,该现象证明片蚀的初期阶段主要受控于径流输沙能力,后期受径流的剥蚀能力控制。在细沟侵蚀阶段,绥德土细沟发育以沟头溯源侵蚀为主,崩塌作用频繁,该侵蚀形式不仅控制着细沟形态的总体特征,也导致含沙量和产沙率均急剧增加,该阶段平均含沙量是相应片蚀阶段的3.25~4.34倍。细沟沟口下方坡面存在明显的泥沙沉积带,表明细沟集中水流的搬运能力远高于坡面漫流,细沟侵蚀主要受径流输沙能力控制。两种土壤的径流流速均表现为坡面下部高于坡面上部,径流稳定后高于径流稳定前,总体来看,绥德土和安塞土上坡和径流稳定后的平均流速分别是下坡和径流稳定前的1.4倍、1.25倍和1.75倍、1.29倍,此外细沟侵蚀或侵蚀强度与微地貌形态之间的互馈作用对径流流速也有较大影响。 相似文献

黄土丘陵沟壑区坡面土壤侵蚀的临界坡度 总被引：5，自引：0，他引：5
坡度是重要的地貌因子.采用岔巴沟径流场和王家沟径流场资料,首先研究坡度与最大30 min雨强(I30)对土壤侵蚀影响,然后确定了主导侵蚀为溅蚀片蚀与主导侵蚀为细沟侵蚀之间的临界雨强,最后探讨了不同侵蚀类型下的临界坡度.结果表明:1.坡度与降雨强度存在明显的交互作用,随着坡度的增大,雨强对土壤侵蚀的影响增大;2.团山沟的溅蚀片蚀与细沟之间的临界I30为0.31 mm/min,同时,该临界雨强不是一定值,受下垫面因素等影响而具有一定的波动范围;3.以溅蚀片蚀为主时,土壤侵蚀存在一个＜31°的临界坡度,侵蚀模数随坡度的变化趋势与径流模数随坡度变化的趋势相同,从9°～31°土壤侵蚀模数随坡度增加是先增加后减小;以细沟侵蚀为主时,在9°～31°间土壤侵蚀不存在临界坡度,土壤侵蚀模数随坡度的变化趋势与径流含沙量随坡度变化的趋势相同,从9°～31°土壤侵蚀模数随坡度增加先逐渐增加后缓慢增加,临界坡度＞31°. 相似文献
