| 1 | Changes of Precipitation Infiltration Recharge in the Circumstances of Coal Mining Subsidence in the Shen-Dong Coal Field,China显示文摘煤采矿沉淀是在采矿区域的一个通用环境地质的问题。由作为研究领域选择 Shen 盾煤采矿沉淀区域,这篇论文在降水渗入学习变化再装在这种情况下借助于领域的煤采矿沉淀,地质的调查和实验室模拟试验,它被期望在采矿区域为 eco 环境的恢复提供一个科学基础。结果显示在沉淀的不稳定的阶段,在 Shen 盾采矿区域的沉淀的三种类型在降水渗入上有积极效果再装,并且完整厚度的基岩沉淀的类型有最大的影响。在沉淀,在长期的干旱以后的降水渗入进程和在通风地区的潮湿移植的稳定的阶段经历三个不同阶段:在降水前的蒸发渗入,渗入向上的渗入渗入在在降水以后的降水和蒸发渗入期间。在一个重降雨渗入过程期间,在好沙,粗糙的沙和罚款粗糙的沙的二元的结构的弄湿的前面运动由二个阶段组成:在降水,弄湿的前面运动距离与深度在有线性关系期间弄湿前面运动的阶段,和在降水,弄湿的前面运动距离与深度在有力量功能关系以后弄湿前面运动的阶段。弄湿的前面运动速度被降雨数量和岩性学在通风地区影响。作为深度增加,然而,运动速度将指数地腐烂。 | ZHANG Fawang SONG Yaxin ZHAO Hongmei HAN Zhantao WANG Dong | 2012 | Acta Geologica Sinica(English Edition)2012，86，4： | 11 |
| 2 | Quantifying the Preferential Flow by Dye Tracer in the North China Plain显示文摘The preferential flow plays a vital role on the infiltration of irrigation or rainfall. The objective of this study was to quantify preferential flow in the processing of irrigation infiltration in the field scale. Tests of different initial soil water contents and irrigation intensities were conducted using Brilliant Blue FCF(C.I.42090) dye tracer in Luancheng County of the North China Plain. The results showed that the percentages of infiltration by the preferential flow for irrigation depth of 25, 50, and 75 mm were 16.67%, 43.67%, and 34.17%, with 19.72%, 61.42%, 66.64% of dyed areas in the soil profile, respectively, which indicated that preferential flow was enhanced with increasing irrigation intensity, but reduced when the irrigation intensity was over 50 mm. The percentages of preferential flow for 75 and 180 mm previous irrigation producing different initial soil water contents were 23.26% and 18.97%, with 53.23% and 39.94% of dyed areas in the soil profile, respectively. Compared with the 75 mm without previous irrigation, the results indicated that higher initial soil water contents restrained the preferential flow in the field. Therefore, intermittent irrigation and low irrigation intensity patterns, and larger depth of plowing would be suggested to reduce the preferential flow which would increase the soil water utilization efficiency and reduce pollution risk of pesticide and fertilizer to groundwater. | Qinghua Wu Chunlei Liu Wenjing Lin Meng Zhang Guiling Wang Fawang Zhang | 2015 | Journal of Earth Science2015，26，3： | 4 |

| 4 | Evolution Characteristics and Influence Factors of Deep Groundwater Depression Cone in North China Plain,China——A Case Studyin Cangzhou Region显示文摘The North China Plain(NCP) is one of the global hotspots of groundwater depletion, groundwater is almost the only source of water for agricultural, industrial and drinking water in this region. After long-term's over-exploitation of deep groundwater, there appeared several deep groundwater depression cones, such as Cangzhou cone, Dezhou cone, Hengshui cone, Tianjin cone, etc., in which the Cangzhou cone is one of the typical cones for its special geography and hydrogeology conditions. In this study, the authors intended to analyze the evolution characteristics and influence factors of deep groundwater depression cone in Cangzhou region, especially the No. III aquifer depression cone, which is the main exploitation zone in this region. Analysis of the evolution of the groundwater depression cone of the No. III aquifer group in Cangzhou region showed that this process can be divided into four stages, namely, development, stable development, rapid expansion, and gradual recovery. The shape and evolution characteristics of the depression cone at different stages are described by analyzing the evolution of the-30,-40, and-50 contours of the groundwater table, for example the closed area of water table contour of-50 m has been enlarged from 95 km2 in 1985 to 6 528.5 km2 in 2005. The dominant factors that affect the evolution characteristics at different stages are proposed. The results showed that relatively long dry periods with less precipitation, special geological and hydrogeological conditions, and sharply increased water consumption for industrial and agricultural development are the main factors that cause the formation of deep groundwater depression cones. Meanwhile, an environmental response against groundwater exploitation is presented, and rational solutions are suggested to avert water crisis. | Yasong Li Fawang Zhang Zhantao Han Ping Wang Honghan Chen Zhaoji Zhang | 2014 | Journal of Earth Science2014，25，6： | 2 |
| 5 | Removal of trimethoprim and sulfamethoxazole in artificial composite soil treatment systems and diversity of microbial communities显示文摘Four artificial composite soil treatment systems(ACSTs)fed with reclaimed water containing trimethoprim(TMP)and sulfamethoxazole(SMX)were constructed to investigate SMX and TMP biodegradation efficiency,ammonia and nitrite removal conditions and the microbial community within ACST layers.Results showed SMX and TMP removal rates could reach 80% and 95%,respectively,and removal rates of ammonia and nitrite could reach 80% and 90%,respectively,in ACSTs.The MiSeq sequencing results showed that microbial community structures of the ACSTs were similar.The dominant microbial community in the adsorption and biodegradation layers of the ACSTs contained Proteobacteria,Chloroflexi,Acidobacteria,Firmicutes,Actinobacteria and Nitrospirae.Firmicutes and Proteobacteria were considerably dominant in the ACST biodegradation layers.The entire experimental results indicated that Nitrosomonadaceae_uncultured,Nitrospira and Bacillus were associated with nitrification processes,while Bacillus and Lactococcus were associated with SMX and TMP removal processes.The findings suggest that ACSTs are appropriate for engineering applications. | Qinqin Liu Miao Li Rui Liu Quan Zhang Di Wu Danni Zhu Xuhui Shen Chuanping Feng Fawang Zhang Xiang Liu | 2019 | Frontiers of Environmental Science & Engineering2019，13，2： | 2 |

| 7 | Removal of sulfamethoxazole and trimethoprim from reclaimed water and the biodegradation mechanism显示文摘Sulfamethoxazole (SMX)and trimethoprim (TMP)are two critical sulfonamide antibiotics with enhanced persistency that are commonly found in wastewater treatment plants.Recently,more scholars have showed interests in how SMX and TMP antibiotics are biodegraded,which is seldom reported previously.Novel artificial composite soil treatment systems were designed to allow biodegradafion to effectively remove adsorbed SMX and TMP from the surface of clay ceramsites.A synergy between sorption and biodegradation improves the removal of SMX and TMP.One highly efficient SMX and TMP degrading bacteria strain,Bacillus subtilis,was isolated from column reactors.In the removal process,this bacteria decade SMX and TMP to NH4^+,and then further convert NH4^+to NO3^- in a continuous process.Microbial adaptation time was longer for SMX degradation than for TMP,and SMX was also able to be degraded in aerobic conditions.Importantly,the artificial composite soil treatment system is suitable for application in practical engineering. | Qinqin Liu Miao Li Xiang Liu Quan Zhang Rui Liu Zhenglu Wang Xueting Shi Jin Quan Xuhui Shen Fawang Zhang | 2018 | Frontiers of Environmental Science & Engineering2018，12，6： | 2 |

| 10 | NUMERICAL SOLUTION OF THE SPACE FRACTIONAL DIFFERENTIAL EQUATION显示文摘In this paper, a space fractional differential equation is considered. The equation is obtained from the parabolic equation containing advection, diffusion and reaction terms by replacing the second order derivative in space by a fractional derivative in space of order. An implicit finite difference approximation for this equation is presented. The stability and convergence of the finite difference approximation are proved. A fractional-order method of lines is also presented. Finally, some numerical results are given. | Zheng Dayi Lu Xuanzhu Liu Fawang | 2005 | Annals of Differential Equations2005，21，3： | 1 |
