5Application of computational fluid dynamic to model the hydraulic performance of subsurface flow wetlands显示文摘A subsurface flow wetland(SSFW)was simulated using a commercial computational fluid dynamic(CFD)code.The constructed media was simulated using porous media and the liquid resident time distribution(RTD)in the SSFW was obtained using the particle trajectory model.The effect of wetland configuration and operating conditions on the hydraulic performance of the SSFW were investigated.The results indicated that the hydraulic performance of the SSFW was predominantly affected by the wetland configuration.The hydraulic effciency of the SSFW with an inlet at the middle edge of the upper media was 0.584 and the best among the SSFWs with an inlet at the top,the middle,and the bottom edge of the upper media.The constructed media affected the hydraulic performance by the ratio(K)of the upper and lower media resistance.The selection of appropriate media resistance in the protection layer can improve the hydraulic effciency.When the viscous resistance coeffcient of the media in the protection layer changed from 2.315×105 to 1.200×108,the hydraulic effciency of the SSFW increased from 0.301 to 0.751.However,the effect of operating conditions on the hydraulic effciency of the SSFW was slight.Liwei FAN Hai Reti Wenxing WANG Zexiang LU Zhiming YANG 2008Journal of Environmental Sciences2008,20,12:17

8Land Use Changes in Northeast China Driven by Human Activities and Climatic Variation显示文摘Human-induced land use/cover change (LUCC) forms an important component of global environmental change. Therefore, it is important to study land use/cover and its change at local, regional and global scales. In this paper we conducted the study of land use change in Northeast China, one of the most important agricultural zones of the nation. From 1986 to 2000, according to the study results obtained from Landsat images, widespread changes in land use/cover took place in the study area. Grassland, marsh, water body and woodland decreased by 9864, 3973, 1367 and 10,052km2, respectively. By comparison, paddy field, dry farmland, and built-up land expanded by 7339, 17193 and 700km2, respectively. Those changes bore an interactive relationship with the environment, especially climate change. On the one hand, climate warming created a potential environment for grassland and marsh to be changed to farmland as more crops could thrive in the warmer climate, and for dry farmland to paddy field. On the other hand, the changed surface cover modified the local climate. Those changes, in turn, have adversely influenced the local environment by accelerating land degradation. In terms of socio-economic driving forces, population augment, regional economic development, and national and provincial policies were confirmed as main driving factors for land use change.WANG Zongming LIU Zhiming SONG Kaishan ZHANG Bai ZHANG Sumei LIU Dianwei REN Chunying YANG Fei 2009Chinese Geographical Science2009,19,3:10
9Crustal Composition of China Continent Constrained from Heat Flow Data and Helium Isotope Ratio of Underground Fluid显示文摘Based on conservation of energy principle and heat flow data in China continent, the upper limit of 1.3 μW/m3 heat production is obtained for continental crust in China. Furthermore, using the data of heat flow and helium isotope ratio of underground fluid, the heat productions of different tectonic units in China continent are estimated in range of 0.58–1.12 μW/m3 with a median of 0.85 μW/m3. Accordingly, the contents of U, Th and K2O in China crust are in ranges of 0.83–1.76 μg/g, 3.16–6.69 μg/g, and 1.0%–2.12%, respectively. These results indicate that the abundance of radioactive elements in the crust of China continent is much higher than that of Archean crust; and this fact implies China’s continental crust is much evolved in chemical composition. Meanwhile, significant lateral variation of crustal composition is also exhibited among different tectonic units in China continent. The crust of eastern China is much enriched in incompatible elements such as U, Th and K than that of western China; and the crust of orogenic belts is more enriched than that of platform regions. It can also be inferred that the crusts of eastern China and orogenic belts are much felsic than those of western China and platform regions, respectively, derived from the positive correlation between the heat production and SiO2 content of bulk crust. This deduction is consistent with the results derived from the crustal seismic velocity data in China. According to the facts of the lower seismic velocity of China than the average value of global crust, and the higher heat production of China continent compared with global crust composition models published by previous studies, it is deduced that the average composition models of global continent crust by Rudnick and Fountain (1995), Rudnick and Gao (2003), Weaver and Tarney (1984), Shaw et al. (1986), and Wedepohl (1995) overestimate the abundance of incompatible elements such as U, Th and K of continental crust.WANG Yang SUN Zhiming 2010Acta Geologica Sinica(English Edition)2010,84,1:10
10Spectral characteristic of infrared radiations of some acupoint and non-acupoint areas in human arm surface显示文摘Using infrared spectrum detective device, we experiment on Neiguan, Laogong and Hegu acupoints of seven adult volunteers as well as contrastive points beside ones. We get 63 infrared spectrums. The experiment outcome tells us that the differences of the intensities among individuals are great, and so are the differences between acupoint and non-acupoint areas. However, the differences of spectral character are small, which indicates that infrared radiations of human body are based on the same biophysical fundament.DING Guanghong YAO Wei CHU Junhao SHEN Xueyong HUANG Zhiming CHENG Huansheng LIU Hui WANG Shenzhang YANG Jing WEI Hu FEI Lun 2001Chinese Science Bulletin2001,46,8:9
11The change in population density from 2000 to 2010 and its influencing factors in China at the county scale显示文摘在人口分发和密度学习变化能为地区性的开发提供重要基础并且计划。空间模式和在在中国的人口密度的变化的开车因素还不是清楚的。用在 2000 和 2010 的人口普查数据,因此,这研究第一在中国分析了人口密度的变化并且在所有 2353 个县把变化划分了成 4 种类型,由快速的增加,慢增加,慢减少和快速的减少组成。随后,基于部分最少的平方(请) 回归方法,我们认出了重要因素(在 11 个自然、社会经济的因素之中) 为有人口变化的不同类型的整个国家和县的影响人口密度变化。结果显示出那:( 1 )在 2010 ,与在 2000 的人口密度相比,在大多数县(超过60%)的人口密度每 km 由 21 个人增加了<啜class=“ a-plus-plus ”> 2 平均,当在另外的县的人口密度每 km 由 13 个人减少了时<啜class=“ a-plus-plus ”> 2 。所有 2353 个县,当 458 和 446 个县分别地在人口密度显示出慢、快速的减少时, 860 和 589 个县分别地在人口密度显示出快速、慢的增加。(2 ) 在 11 个因素之中,社会经济的因素比自然因素更显著地影响了人口密度变化。更高经济的发展水平,更好医药的条件和更强壮的通讯能力是人口增加的主要的拉因素。稠密的人口密度是人口减少的主要的推因素。这些结论在过去的 10 年在中国澄清了人口变化和它的影响因素的空间模式并且能为计划的未来人口提供有用参考。WANG Lu FENG Zhiming YANG Yanzhao 2015Journal of Geographical Sciences2015,25,4:8

17Identification of odorous compounds in reclaimed water using FPA combined with sensory GC-MS显示文摘Odorous compounds in the influent of a reclaimed water treatment plant (RWTP),consisting of coagulation,sedimentation,continuous micro-filtration (CMF),and chlorination in succession,in a north China city,were identified by combining flavor profile analysis (FPA) with sensory gas chromatograph-mass spectrometry (GC-MS).The sewery/swampy/septic odor with an odor intensity of 6.4 was found to be the major odor group in the RWTP influent,and the existence of well-known odorant including dimethyl disulfide,dimethyl trisulfide,indole and skatole were confirmed using GC-MS.The result of a spiking test showed that the intensity (3.6) of the sewery/swampy/septic odor caused by these four chemicals contributed to over 50% of the odor intensity of the influent.The FPA intensity for sewery/swampy/septic odor in the RWTP effluent was 3.8,showing that the treatment process was not efficient for the removal of odorants,particularly indole and skatole.Zhiming Yan Yu Zhang Jianwei Yu Hongying Yuan Min Yang 2011Journal of Environmental Sciences2011,23,10:6
