辽河口湿地芦苇群落退化过程中土壤营养元素和含盐量变化

2011年8月,在辽河口芦苇(Phragmites australis)沼泽采集土壤样品,在室内对土样进行测试分析,研究芦苇群落退化演替过程中,芦苇沼泽土壤营养元素和含盐量的变化.结果表明,在芦苇群落退化过程中,土壤有机质含量先增加后减少,土壤全氮和全磷含量的变化也有相似规律,二者与土壤有机质含量呈显著正相关,说明土壤中氮和磷的来源主要是动植物残体积累;土壤速效钾和易溶盐含量呈逐渐增加的趋势;土壤营养元素和含盐量的垂直分布表明,随着土壤深度的增加,土壤有机质含量、全氮含量、速效钾含量和易溶盐含量逐渐降低,但全磷含量无明显变化.     

小流域自然土壤与耕作土壤养分比较及影响因素分析

通过对河北省易县观坐岭小流域自然土壤和耕作土壤有机质、速效氮、速效磷、速效钾及微量元素有效含量的测定分析,得出了该小流域自然土壤和耕作土壤的肥力状况.结果表明:自然土壤中有机质和速效氮含量处于较高水平;速效钾含量丰富,速效磷比较缺乏;有效Fe、Mn含量处于高水平,有效Cu、Zn含量中等.自然土壤开垦为耕作土壤后,有机质和速效氮含量下降;由于施肥原因,速效磷含量明显增高;速效钾含量因母质影响有所下降.海拔与土壤养分变化的相关性小明显,不同坡位土壤养分表现出向下汇集的趋势.并从自然环境、人为影响、地形母质等方面分析土壤养分变化的影响因素.     

三江源花石峡地区植被退化与土壤养分的关联

为探索三江源区草地退化过程中植被与土壤养分之间的关联性,对果洛州玛多县花石峡地区不同退化梯度草甸的植被特征和土壤养分进行了相关性分析。结果表明:在山地草甸梯度退化过程中,优质牧草丰富度、盖度均降低,低产杂草类植被比例增加;随着退化梯度加剧和土壤剖面加深,土壤养分梯度变化明显,有机质含量明显下降,土壤呈碱化趋势,速效磷含量下降。植被盖度与土壤速效磷、p H值、有机质含量呈高度关联性。有机质和磷肥是植被恢复重建的关键。     

东祁连山高寒草甸土壤理化性质对海拔和坡向的响应及其与植被特征的关系

为了探索高寒草甸土壤理化性质对海拔和坡向的响应及其与植被的关系,以东祁连山高寒草甸为研究对象,分析了7个海拔和2个坡向高寒草甸的土壤养分含量和生态化学计量比变化规律及其与植被的关系。结果表明：（1） 土壤含水量、电导率、有机碳、全氮、全钾、碱解氮、速效磷、速效钾含量、碳磷比（C/P）和氮磷比（N/P）随海拔的升高呈先升高后降低的趋势,土壤容重、全磷和碳氮比（C/N）呈先降低后升高的趋势。（2） 同一海拔,大部分海拔梯度阳坡的土壤土壤容重、速效钾、电导率和全磷高于阴坡,阳坡的土壤含水量、速效磷、C/P和N/P低于阴坡,海拔3200 m梯度以下阳坡的土壤有机碳、全氮、碱解氮和C/N低于阴坡。（3） 不同海拔和坡向的高寒草甸土壤C/N、C/P和N/P处于14.55~38.13、12.61~87.94和0.27~5.01之间。（4） 冗余分析（RDA）发现,土壤容重、全氮和速效磷是影响高寒草甸植被的关键土壤因子,聚类分析发现海拔3200~3400 m的阴坡和阳坡聚为一类。综上所述,东祁连山高寒草甸土壤养分和生态化学计量比随海拔和坡向的变化呈规律性变化,基于对N/P比的分析发现,该区域高寒草甸类草原的初级生产力主要受土壤氮限制且低海拔和高海拔区域尤为明显,基于聚类分析发现,海拔3000 m和3400 m是该区域草地植被和土壤特征发生变化的临界线。建议在高寒草甸类草原的管理过程中,应该充分考虑海拔和坡向的分异性特征。     

流沙地恢复过程中土壤特性演变研究

以毛乌素沙地西南缘的盐池县沙边子及位于腾格里沙漠东南缘的沙坡头地区为例,研究了该地区不同程度沙漠化土地恢复过程中土壤机械组成及土壤养分的动态变化。结果表明:不同地区或同一地区不同区域的沙漠化土地中,随着植被盖度的增加及恢复程度的增强,土壤中的粉粒、粘粒含量都有显著增加（P<0.05）,土壤质地向着壤质化和细粒化方向发展;土壤的有机质、全氮、全磷含量也有显著增加（P<0.05）;速效氮、速效磷含量也有相应的增加。土壤有机质、全氮和全磷的含量与土壤粉粒、粘粒含量呈显著正相关,且前三者之间也呈极显著正相关;但是土壤粉粒和粘粒含量与速效氮、速效磷和速效钾之间的关系则因区域和土地利用的不同表现出明显的差异。     

放牧对阿拉善荒漠草地土壤性状的影响

对阿拉善荒漠草地不同放牧条件下土壤理化性状的变化进行了研究,结果表明:在草地基况一致的条件下,经过连续6a不同强度的放牧,0~ 20cm土层土壤容重轻牧和重牧区低于中牧区。随着放牧强度的增加,土壤颗粒组成极粗砂、粗砂和中砂含量增加,细砂、极细砂、粉砂和粘粒含量减少,过度放牧加快了土壤风蚀沙化。0~20cm土层中土壤有机C、全P的含量和C/N随着放牧强度的增加而依次降低;全N、全K、pH末发生明显变化;速效N和速效K重牧区显著高于轻牧区和中牧区;速效P轻牧区高于中、重牧区。土壤有机C与全P、速效P呈显著正相关;全P与速效N和K呈显著负相关,与速效P呈显著正相关(P<0.05)。     

祁连山中段青海云杉林土壤肥力质量评价研究

以祁连山排露沟流域青海云杉林为研究对象，研究了海拔梯度上土壤肥力因子的分布特征及变化规律，并运用主成分分析法对青海云杉林土壤肥力状况进行了评价。结果表明：（1）研究区土壤呈碱性，pH值均大于8.0；高海拔地区（3 300 m）含水量达到过饱和状态，各土层含水量均大于100%；随海拔升高，全氮含量呈增大趋势，全钾含量呈减小趋势，而全磷含量呈先减小后增大趋势；不同海拔梯度速效磷含量差异不显著（P>0.05），海拔3 300 m处速效钾含量显著高于其他海拔段（P<0.05）。（2） 不同海拔梯度下土壤有机质、全氮、全磷、全钾、速效磷和速效钾含量都有明显的“表聚效应”，其中3 300 m处0~10 cm土层有机质含量高达325.93 g·kg^-1，是本海拔段其他土层的1.6~1.8倍，是同土层其他海拔段的1.3~2.0倍。（3） 土壤肥力因子间关系密切，土壤含水量与有机质、全氮呈极显著正相关关系，与土壤容重、pH和全钾呈极显著负相关关系，土壤养分含量之间存在不同程度的显著正相关关系。（4） 不同海拔梯度土壤肥力质量为：3 300 m>3 200 m>3 100 m>3 000 m>2 900 m。     

区域尺度土壤养分空间变异及其影响因素研究

江苏北部5市土壤表层(0~20cm)全氮含量连云港东北部、淮安南部和盐城西部显著高于其它地区;全磷含量呈现由北到南、自西向东升高的趋势;速效磷含量高值区位于北部的灌云县和南部的金湖县;速效钾含量东部沿海高于其它地区。土壤类型和成土母质对土壤养分产生显著影响:对于土类而言,沼泽土和水稻土养分较高;各成土母质中,湖相沉积物发育的土壤养分含量最高。在研究区1:5万尺度范围内,土壤类型对全氮和全磷的变异起主导作用,而速效磷受成土母质的影响较大,土壤类型和成土母质对速效钾的影响较小,土壤类型和成土母质对全量养分的影响要大于速效养分。     

阿拉善荒漠草地恢复初期植被与土壤环境的变化

对阿拉善荒漠草地恢复初期(1998-2001)植被特征和土壤养分的变化进行了研究。结果表明:草地恢复过程中,植被的盖度和生物量比封育前分别增加272%~536%和44.39%~305.3%。植被的恢复使土壤理化性质发生了变化,与封育前相比土壤中有机质、全N、速效K以及细砂、特别细砂和粘粒含量显著增加;速效N、速效P降低。土壤有机质、全N和全P的含量与土壤中<0.05 mm颗粒和速效K含量呈极显著正相关,并且前三者之间也呈极显著正相关(P<0.01)。     

阿拉善荒漠草地几种灌木对土壤有效态养分的影响

对阿拉善荒漠草地广泛分布的几种灌木、半灌木土壤有效态常量和微量营养元素的“肥岛”效应进行了研究。结果表明：①霸王、白刺、红砂和沙冬青提高了灌丛根部土壤速效Na、K、Fe和Mn 的含量,而降低了灌从根部土壤速效Ca、Mg的含量;驼绒藜除对土壤速效Mg含量有显著影响外,对其他元素无显著的影响。②霸王、白刺和沙冬青对速效Na、K、Fe和Mn有明显的富集作用,对速效Ca负富集作用;红砂对速效Na有极强的富集作用,EA、EB分别为37.59和52.93;除红砂和驼绒藜对速效Mg有富集作用外,其余灌丛对速效Mg无富集作用。③灌丛周围土壤pH值与速效K、Fe和Zn含量呈显著负相关,与Ca呈正相关,与速效Na无相关性。霸王、白刺、沙冬青周围土壤速效Mg含量与pH值也呈显著正相关;除了霸王外,其他灌木周围土壤速效Mn含量都与pH值呈负相关。
