| 1 | 植物功能性状对土壤保持的影响研究述评显示文摘植被对土壤保持具有重要的影响,但是从植物功能性状的角度总结评述植被对土壤保持影响的研究并不多见。总结评述了植物地上功能性状、地下功能性状对土壤保持功能的影响以及植物地上、地下功能性状的关系,认为:(1)植被地上部分功能性状对土壤保持的作用主要体现在对溅蚀、面蚀的影响及间接改变土壤理化性质等方面,其功能性状指标主要包括叶面积、叶长、叶宽、枝数、植被高度等;(2)植被地下部分功能性状对土壤保持的作用主要体现在固持土壤、提高土壤抗剪切强度、提高土壤抗侵蚀能力、增强土壤渗透性,植物根系固持土壤与根系抗拉能力密切相关,植物根系土壤的物理和水文性质,与细根比例、根长密度、根表面积等性状密切相关;(3)可以通过植物地上部分功能性状间接反映地下部分功能性状,但是现有研究多为定性认识;(4)在植物功能性状对土壤保持的研究中亟待加强植被地上地下功能性状的长期定位监测,深化植被功能性状尤其是根系特征与土壤保持的作用机理,加强植被地上部分、地下部分功能性状的定量表达,建立植被功能性状与土壤保持功能的定量关系,实现植被功能性状与土壤保持功能特征的动态链接。 | 王晶 赵文武 刘月 贾立志 | 2019 | 生态学报2019，39，9： | 21 |
| 2 | 新疆洪水管理与土壤水库重建显示文摘使用《新疆统计年鉴》和第二次全国水土流失遥感监测数据,分析新疆洪水灾害发生的时空特征及其与土壤水力侵蚀的关系。结果表明:1990—2010年间,新疆洪水灾害面积平均为每年642.6 km2。昌吉回族自治州、伊犁州直属县(市)、和田地区和阿勒泰地区洪水面积占新疆洪水总面积的58.8%。新疆洪水灾害面积仅占土壤水力侵蚀面积的0.56%。水土保持生态修复是防治土壤侵蚀和洪灾的根本措施。通过植被覆盖,可增加地表径流入渗,重建土壤水库。从土壤水库重建的角度,提出了一些防治洪水灾害的措施。 | 张文太 | 2013 | 中国水土保持科学2013，11，S1： | 4 |
| 3 | Using live vegetation volume to analyze the effects of plot Pinus massoniana Lamb on water and soil conservation under natural rainfall events显示文摘The 3-D spatial distributions of vegetation arc of great significance for water and soil conservation but arc rarely concerned in literatures.The live vegetation volume(LVV) was used to relate to water/soil loss under 144 natural erosive rainlall events from 2007 to 2010 in a typical water-eroded area of southern China.Quadratic polynomial regression models were established for five pure tree(Pinus massoniana Lamb) plots between LVV and water(runoff)/soil conservation effects(RE/SE).RE/SE corresponds to the ratios of runoff depth/soil loss of the pure tree plots to that of the control plot under each rainfall event.Increasing LVV exhibits descending(DS),descending-ascending(DA),ascending-descending(AD),and ascending(AS) trends in the LVV-RE and LVV-SE curves.The effects of soil conservation on the plots were generally more noticeable than the effects of water conservation,and most of the RE and SE values reflected the positive effects of water and soil conservation.The effects were mainly positive under heavy rains(e.g.,rainfall erosivity,R = 140 MJ mm ha^(-1) h.maximum 30min intensity,I_(30)= 16 mm h^(-1)),whereas the effects were mainly negative under light rains(e.g.,R = 45 MJ mm ha^(-1),I_(30) = 8 mm h^(-1)).The trees' water/soil conservation effects notably transformed when rainfall erosivity and intensity were lower than the positive or negative effects to a certain threshold.About 50%rainfall events led to obvious transform effects when LVVs were near 0.5 or 0.6.These results are able to aid in the decision making on the forest reconstruction in water-eroded areas. | Zhu-jun GU Xiao-xia WU Xiao-lei WANG Shao-yun PENG Hao LUO Xue-zheng SHI Dong-sheng YU | 2013 | International Journal of Sediment Research2013，28，4： | 3 |
| 4 | 植被三维结构对水蚀红壤粒径分布及养分含量的作用显示文摘基于福建省长汀县河田镇48个样区(15 m×15 m)植被垂直分层类型,不同垂直层次的总体植被覆盖度、枯落物厚度、土壤粒径分布及养分含量3类土壤属性数据,分析植被特征与土壤属性间的相互关系,并比较不同侵蚀程度、不同垂直结构类型下植被覆盖度、枯落物厚度与土壤粒径分布及养分含量的差异。结果表明,植被覆盖度、枯落物厚度与侵蚀程度显著负相关,与土壤中有机质含量、全氮含量、全磷含量显著正相关,但与全钾含量差异不显著。当植被覆盖度达到50%、枯落物厚度达到20 mm时、可以有效保持水土,其中枯落物较上层植被的水土保持作用更明显。不同植被垂直结构组合中,选择林灌草、林灌、灌草、纯草均可以较好地促进植被生长、改良土壤结构、保持土壤肥力。 | 顾祝军 罗昊 | 2015 | 江苏农业科学2015，43，7： | 2 |
| 5 | 利用地基激光雷达估算不同地表条件下土方量显示文摘不同地表条件下土方量估算对土壤侵蚀量监测以及高标准农田工程建设具有重要意义,但基于地基激光雷达(Terrestrial Laser Scanning,TLS)的估算精度尚需求证。在江西省鹰潭市红壤生态实验站获取了7种不同地表条件下(植被覆盖度、砾石含量、地形起伏)填/挖土前后两期TLS数据,采用移动曲面拟合滤波与反距离加权插值方法计算填/挖土方量并验证,分析了TLS测站数量、位置与点云间距对计算精度的影响。结果表明:1)TLS在不同地表条件下估算土方量误差为1.69%~18.17%;2)在保证土方量计算精度的前提下,植被覆盖度分别小于1%、20%~30%的样方可将测站数量减少至2和3个,低地势测站位置更有利于获取地表完整信息;3)TLS计算土方量的精度随点云间距增加而降低,近地表无覆盖、有覆盖的样方最优点间距分别为1~8和1~4 cm。研究为估算厘米级土体三维时空变化研究提供技术支持,为TLS野外观测设置提供依据。 | 冯凯月 马利霞 陈洋 王鑫 宋洁 于东升 | 2021 | 农业工程学报2021，37，23： | 2 |
| 6 | A Catastrophe Model to Assess Soil Restoration Under Ecological Restoration in the Red Soil Hilly Region of China显示文摘Current methods that utilize simple data or models to evaluate soil restoration under ecological restoration are not sufficiently rigorous.Soil restoration under ecological restoration measures was evaluated in the red soil hilly region of China by applying the catastrophe model.Among 89 soil sites selected,26(29.21%) were in the middle lobe,10(11.24%) in the upper lobe,and 53(70.79%)in the lower lobe of the process surface in the Cusp catastrophe model.The catastrophic direction of the 26 unstable soil sites was to the upper lobe of the process surface according to vegetation cover change and fieldwork.There was a significant negative correlation of the variation in bifurcation set(? value) with vegetation cover increase,and a higher vegetation cover increase was related to higher unstable probability.The four ecological restoration measures were listed in the order:low-quality forest improvement(LQFI)>arbor-bush-herb mixed plantation(ABHMP)>orchard improvement(OI)>closing measures(CM) according to the proportions of unstable soil sites,which were all higher than no restoration measure,while they were in the order:LQFI | CHEN Zhiqiang CHEN Zhibiao BAI Liyue ZENG Yuee | 2017 | Pedosphere2017，27，4： | 2 |
