Patterns of Resource Recycle Utilizing Sewage-soil-plant Systems: Ecological Engineering FLTS for Domestic Sewage [PDF]
, 2004 本文以厦门市狐尾山和仙岳山的原生生活污水林地生态处理系统（FLTS）为例，提出了“氧化塘+污水动力输送、管网投配+林地+再生水回收”的污水－土壤－植物资源再生范式，通过对该系统关键生态过程的研究，解决了FLTS生态工程运行技术参数。FLTS实验林地分为马尾松次生林和人工速生巨尾桉林，林地土壤属南亚热带丘陵台地典型的赤红壤性砂土，机械组成空间差异明显。不同林型比较，短期轮伐集约栽培（SRIC）下巨尾桉速生林平均年生物量积累明显优于次生马尾松林。N、P、K元素年累积量分别较马尾松林高出1.66～3.50倍 ...

Shuitu Baochi Xuebao, 2018 通过室内一维垂直土柱试验，利用TDR和张力计分别研究土壤中纳米碳混合层对土壤水分入渗特性、土壤水分分布以及纳米碳混合层对土壤水分特征曲线的影响。结果表明：（1）随着入渗时间的增加，含有纳米碳的土壤在相同入渗时间内累积入渗量减少，湿润锋推进距离明显减小，施加纳米碳具有明显的减渗作用。利用Philip入渗模型拟合入渗数据，吸渗率S随着纳米碳含量的增加而减小，随着纳米碳含量的增加，水分入渗初期的累积入渗量逐渐减小。对湿润锋分层进行线性拟合，在湿润锋进入第2层土壤时，入渗速率有了显著的降低 ...
