Damage to Alexandrlum tamarense DNA Caused by Hydroxyl Radicals [PDF]
, 2016 利用羟基自由基(·OH)压载水处理系统,采用大气压强电场放电技术制取·OH溶液对塔玛亚历山大藻(Alexandrlum tamarense)进行处理。通过普通光学显微镜,荧光显微镜和电子显微镜对·OH处理前后的塔玛亚历山大藻的细胞结构进行观测。结果表明,·OH能有效破坏藻细胞,从而造成藻类死亡。利用随机扩增多态性DNA(random amplification polymorphic DNA,RAPD)和实时定量PCR(RT-PCR)相结合的技术检测·OH对DNA链的破坏作用 ...

World Water Policy, Volume 10, Issue 4, Page 1170-1186, November 2024.Abstract Sustainable land management (SLM) practices is a key to reducing rates of land degradation and has proven to ensure water security by increasing soil moisture availability, decreasing surface runoff, decreasing soil erosion, increasing infiltration, and decreasing flood discharge. Land degradation is adversely affecting over 75% of the Earth's

Research on Bamboo Riparian Buffer Ecosystems for Diffuse Pollution Prevention [PDF]
, 2010 进入农业系统的过量氮(N)、磷(P)极易通过地表径流或地下潜流、渗漏及农田排水进入水环境，引发水体富营养化。具有一定群落结构的河岸植被土壤系统内部具有较大的生物生存空间和相互作用区域，其间生物地球化学联合机制，可以减缓径流、捕获泥沙、截断或去除地表径流、壤中流或渗漏水及浅层地下水中的氮磷等元素，有效改善受纳水体的水质。了解河岸植被土壤系统削减污染物和净化水质的机制及其影响因素，有助于加强对河岸带的管理和重建工作，为防治面源污染提供科学依据。 本文采用土壤剖面渗透水分层采集装置 ...

Shuitu Baochi Xuebao, 2007 在红壤丘陵区，对自然降雨条件下坡地（上层0～40cm，下层40～110cm）降雨壤中流产流过程进行了研究，结果表明：不同土地利用方式下，油茶林壤中流产流量大于同层恢复区；壤中流峰值流量恢复区大于同层油茶林；油茶林壤中流产流过程较恢复区开始早、结束晚。随着土层加深，滞后时间延长。同一土地利用方式下，产流量、峰值流量、滞后和拖尾均为上层小于下层。壤中流对降雨及地表径流的响应均为上层快于下层。不同的降雨类型，壤中流产流机理不同。峰值型降雨壤中流产流过程滞后时间较小，壤中流产流类型多为驱赶流。

Study on Nitrogen Retention in Riparian Vegetation System [PDF]
, 2009 随着经济发展和人口增加，世界范围内水体污染日趋严重，已经成为限制经济社会发展和威胁人类健康的重大环境问题。河岸植被土壤系统能显著减少地下水和地表水中的污染物进入水生生态系统。在我国南方丘陵地区，广泛种植的竹林是常见的次生植被群落，因此对河岸竹林土壤系统的深入研究，对于防治我国的环境污染和受纳水体的富营养化问题具有十分重要的理论和现实意义。 本文利用具有创新意义的土壤壤中流采集装置，结合水样氮素的分析与土壤反硝化实验，将河岸植被土壤作为一个系统，了解其内部的主要生物地球化学过程 ...
