| 1 | Soil Properties and Plant Growth Response to Litter in a Prolonged Enclosed Grassland of Loess Plateau, China显示文摘The enclosure and ungrazing practices for grassland management result in accumulation of plant litter on soil surface thus affecting the available soil water and nutrients for plant production. We experimentally investigated the effects of litter on soil properties and plant growth in a prolonged enclosure grassland of Loess Plateau, China. Three different litter manipulations were conducted including removal of all litter, an untreated in-situ control with original litter levels, and a double litter treatment. Litter treatment experiments demonstrated that plant litter affected the superficial soil water. Soil water content in plots with in-situ or double litter is generally higher than that with litter removal. The depletion of soil water up to five days post rainfall is fastest in litter removal plots for the top soil, but no evident difference for the deep ones. Different litter treatments have no significant impact on soil total carbon, nitrogen as well as carbon/nitrogen ratio for consecutive two years experiments. Both above-and below-ground biomasses in plots of litter removal were less than those in the plots of in-situ and double litter treatment. Litter affects plant production mainly through the mechanical barrier regulating root zone soil moisture. Therefore, prolonged litter manipulation experiments are desirable to understand the long-term response of plant growth on litter from nutrient aspect. | Yunwu Xiong Bing Yu Mengting Bai Xueyang Zhang Guanhua Huang Alex Furman | 2019 | Journal of Earth Science2019，30，5： | 2 |
| 2 | 基于跨孔电阻率CT的污染阻隔帷幕性能检测显示文摘为克服传统钻孔取样和常规阵列测量的跨孔电阻率法在帷幕检测工作中的不足,采用阵列优化方法对3种常规跨孔电阻率阵列进行优选,构建了高分辨率和高信噪比的阻隔帷幕测量组合阵列。采用数值模拟方法对该组合阵列进行阻隔帷幕检测效果验证,并应用于某垃圾填埋场的阻隔帷幕性能检测。根据垃圾填埋场2处阻隔帷幕的跨孔电阻率CT探测结果得出:膨润土阻隔帷幕主体在固结初期表现为均匀完整的低阻带,电阻率为0.001~0.06Ω·m,2处阻隔帷幕的注浆影响半径分别为0.55,0.95 m,满足帷幕厚度和完整性要求。结合阻隔帷幕芯样的渗透系数测试分析得出:2个测量区域阻隔材料渗透系数均<10^(-6)cm/s,满足污染阻隔的性能要求。利用组合阵列的跨孔电阻率CT技术,实现对污染场地阻隔帷幕完整性和防渗性能的高效准确评价。 | 马新民 毛德强 闫利刚 刘登峰 李书鹏 张家铭 Alex Furman 王京 | 2023 | 环境工程2023，41，8： | 0 |
