| 1 | Modular growth and clonal propagation of Hippophae rhamnoides subsp, sinensis in response to irrigation intensity显示文摘A multipurpose clone plant species,Hippophae rhamniodes has the capacity for indefinite longevity,although under successive drought stress it may often decline or die across large areas.Field trials were conducted over 2 years to examine the effects of varied irrigation intensities on modular growth and clonal propagation in a semi-arid area.Irrigation levels included a control,as well as two,four and six times the volume of water that was typically received via local annual average precipitation.Irrigation intensity significantly influenced clonal propagation capacity(number of daughter ramets),aboveground modular growth(height,base diameter,and crown width),belowground modular growth included root nodule dry weight,stretching capacity of lateral roots(length of the longest lateral roots,and diameter of firstgrade lateral roots),and branching intensity of lateral roots(number of lateral roots bifurcation grade,number of firstgrade lateral roots).The modular growth and the density of daughter ramets were small under non-irrigation or low irrigation,and became larger with increased irrigation intensity.Beyond a certain threshold,however,further increases in irrigation intensity resulted in a reversion to the development.The optimal irrigation intensities for growth and propagation were 3.48–5.29 times the volume of nominal local annual average precipitation.There were effects of irrigation intensities on the positive significant correlations between aboveground and belowground modular growths,and on clonal propagation capacities.Under various water treatments,H.rhamnoides may adapt to the environment through the regulation of growth and propagation.We concluded that water shortages act to weaken the growth and propagation of H.rhamniodes plantations. | Zilin Cao Tianjiang Li Genqian Li Chunhong Liu Haiyin Gao Guanghui Dai Zhiyong Xiao Sunling Li | 2016 | Journal of Forestry Research2016，27，5： | 14 |
| 2 | A new approach to quantifying vehicle induced turbulence for complex traffic scenarios显示文摘Traffic-related pollutants adversely affect air quality, especially in regions near major roadways. The vehicleinduced turbulence(VIT) is a significant factor that controls the initial dilution, dispersion, and ultimately the chemical and physical fate of pollutants by altering the conditions in the microenvironment. This study used a computational fluid dynamics(CFD) software FLUENT to model the vehicle-induced turbulence(VIT) generated on roadways, with a focus on impact of vehicle-vehicle interactions, traffic density and vehicle composition on turbulent kinetic energy(TKE). We show, for the first time, that the overall TKE from multiple vehicles traveling in series can be estimated by superimposing the TKE of each vehicle, without considering the distance between them while the distance is greater than one vehicle length. This finding is particularly significant since it enables a new approach to VIT simulations where the overall TKE is calculated as a function of number of vehicles. We found that the interactions between vehicles traveling next to each other in adjacent lanes are insignificant,regardless the directions of the traffic flow. Consequently, simulations of different traffic scenarios can be substantially simplified by treating two-way traffic as one-way traffic, with less than 5% difference in the overall volume-averaged TKE. We also developed equations that allow the estimation of the overall volume-averaged TKE as a function of the number and the type of vehicles. | Yesul Kim Li Huang Sunling Gong Charles Q.Jia | 2016 | Chinese Journal of Chemical Engineering2016，24，1： | 2 |

| 7 | Modeling study on the roles of the deposition and transport of PM_(2.5) in air quality changes over central-eastern China显示文摘The role of PM_(2.5)(particles with aerodynamic diameters≤_(2.5)μm)deposition in air quality changes over China remains unclear.By using the three-year(2013,2015,and 2017)simulation results of the WRF/CUACE v1.0 model from a previous work(Zhang et al.,2021),a non-linear relationship between the deposition of PM_(2.5)and anthropogenic emissions over central-eastern China in cold seasons as well as in different life stages of haze events was unraveled.PM_(2.5)deposition is spatially distributed differently from PM_(2.5)concentrations and anthropogenic emissions over China.The North China Plain(NCP)is typically characterized by higher anthropogenic emissions compared to southern China,such as the middlelow reaches of Yangtze River(MLYR),which includes parts of the Yangtze River Delta and the Midwest.However,PM_(2.5)deposition in the NCP is significantly lower than that in the MLYR region,suggesting that in addition to meteorology and emissions,lower deposition is another important factor in the increase in haze levels.Regional transport of pollution in central-eastern China acts as a moderator of pollution levels in different regions,for example by bringing pollution from the NCP to the MLYR region in cold seasons.It was found that in typical haze events the deposition flux of PM_(2.5)during the removal stages is substantially higher than that in accumulation stages,with most of the PM_(2.5)being transported southward and deposited to the MLYR and Sichuan Basin region,corresponding to a latitude range of about 24°N-31°N. | Lei Zhang Jianjun He Sunling Gong Xiaomei Guo Tianliang Zhao Huizheng Che Hong Wang Chunhong Zhou Jingyue Mo Ke Gui Yu Zheng Lei Li Junting Zhong Xiaoye Zhang | 2023 | Journal of Environmental Sciences2023，，1： | 0 |
