Analysis and Evaluation of Atmospheric Precipitation in Weinan of Shaanxi Province

According to the distribution Weinan, the atmospheric precipitation characteristics of atmospheric precipitation in monitoring station of Weinan and atmospheric precipitation monitoring station of Nanjiao Village in Linwei District were set up. After one year of monitoring and analysis of the atmospheric precipitation in Weinan, the precipitation amount, pH value, and the change characteristics of conductivity of the atmospheric precipitation were obtained. The concentrations of five kinds of cation （Ca^2＋,NH^4＋,Mg^2＋,Na^＋,K^＋） and four kinds of anion （F^-,Cl^-,SO4^2-,NO3） in the precipita- tion of Weinan and Nanjiao Village were determined by ion chromatography. The results showed that the concentration of SO3 and NO3 in atmospheric precipitation of Weinan changed significantly, while there was no significant change observed on the concentration of F^-, Cl^-, Mg^2＋, K^＋ and Na^＋ in a year.

GEOCHEMICAL RECORDS OF PALAEOCLIMATIC CHANGES IN WEINANSECTION SINCE THE LAST INTERGLACIAL

Weinan section consists of Holocene soil SO, last glacial loess L1, and last interglacial soil S1, furtherly L1 can be subdivided into three layers of loess (L1-1, L1-3, and L1-5), and two layerS of weakly developed soil (L1-2 and L1-4). Based on studying the content variations of Carbonate, free Fe2O3, and the total organic content in Weinan section, the environmental evolution of this region has been discussed over the last glacial-interglacial cycle. Our results indicate that the chemical parameters can be ed as climatic proxy data, and the variations of these indexes reflect the cyclic nature of the Quaternary climatic change. In addition, the climatic records of Weinan section can also be correlated with that of the marine oxygen isotope records, so the environmental evolution of the Loess Plateau is also consistent with the global climatic changes. The unexpected finding is that the climatic curve of L1-5, which can be correlated with stage 4 of marine oxygen isotope records, consists of three troughs and two sandwiched peaks, and may suggest the existence of the second-order warmcold oscillations of this period.

Impact of Long-Term Fertilization on Cropland Soil Fauna Community at Loess Soil, Shannxi, China

The relationship between long-term fertilization and cropland network for soil fertility and fertilizers in Loess soil of Shannxi soil fauna was studied at the station＇s experiment research Provincefrom Jul. 2001 to Oct. 2002. Six types of long-term fertilizer were carried out for this study including non-fertilizer （CK）, abandonment （ABAND）, nitrogenous and phosphors and potassium fertilizers combined （NPK）, straw and NPK （SNPK）, organic material and NPK （MNPK） and 1.5 times MNPK （1.5MNPK）. 72 soil samples were collected and 5 495 species of cropland soil fauna obtained by handsorting and Cobb methods at 4 times, belonging to 6 Phyla, 11 Classes, 22 Orders, 2 Superfamilies, 61 Families and 35 Genera. The result showed that different fertilizer had significantly impacted on the cropland soil fauna （F = 2.24, P〈0.007）. The number of the cropland soil fauna was related to the soil physicochemical properties caused by long-term fertilization. The result by principal component analysis, focusing on the number of 15 key soil fauna species group＇s diversity, evenness of community and the total soil fauna individuals indicated that the effects of SNPK, NPK, MNPK and 1.5MNPK were significantly different from that of the cropland soil fauna, in which, SNPK and NPK had the positive effect on cropland soil fauna, and MNPK and 1.5 MNPK had the negative affect, others could not be explained. By principal component I, the synthetic effect of different fertilization on the total soil fauna individuals and the group was most significant, and the effect was little on evenness and diversity. By value of eigenvectors, the maximum one was 9.6248, and the minimum one was - 1.0904, that means the 6 types of fertilization did not affect evenly the cropland soil fauna.

Reservoir Characteristics and Main Controlling Factors of the Flow III Section of the K Oilfield in the Weixinan Depression

In order to clarify the reservoir characteristics and main controlling factors of the flow three section of the K oil field in the Weixinan Depression, a study on the reservoir characteristics and main controlling factors of the flow three section of the K oil field in the Weixinan Depression has been carried out by utilizing the data of cores, casting thin sections, physical property tests and logging wells. The results show that the lithology of the reservoir in the flow three section of the study area is dominated by coarse sandstone and medium sandstone, followed by conglomerate-bearing sandstone and sand conglomerate. The porosity is mainly distributed in the range of medium-high porosity, and the permeability is mainly medium seepage, and the overall physical properties are good. The three sections of the stream in the study area mainly include four sedimentary microphases, namely, underwater diversion channel, estuarine dam, mat sand and inter-diversion bay. The underwater diversion channel has the best physical properties, characterized by coarse grains and low mud content. The medium and coarse sand content of various lithologic reservoirs is the main factor in the formation of high-quality reservoirs. Rock-forming action is an important factor affecting the physical properties of local reservoirs, comparing the compaction, cementation and dissolution between different sedimentary microphases, the underwater diverging river has the lowest rate of compaction and pore reduction, the highest rate of pore increase by dissolution, and the best physical properties. Therefore, the weakly cemented-strongly dissolved coarse sandstone phase developed in the microphase of the underwater diversion channel in section 3 of the flow in the study area is the most favorable reservoir.

The elemental carbon record in Weinan loess section since the last 21 ka

We studied the records of elemental carbon (EC) of the last 21 ka in the Weinan loess section, Shanxi Province. The variations of EC abundance and δ13CEC value along with depth (or age) were presented. There are four large peaks of EC abundance around the following years: 20.16 ka, 17.76 ka, 11.97 ka and 4.49 ka. Climatic situation was changed rapidly during these periods. The peaks around 11.97 ka and 20.16 ka are particularly sharp, occurring over intervals of tens to hundreds of years, which could represent short-duration intense events. δ13CEc values in the upper 4 m of the Weinan loess section vary between -11.71‰ and -21.34‰, which suggests that the vegetation pattern of the last 21 ka on the Loess Plateau is G4-dominated grasses.

泾阳-渭南活动断裂带场地形变与地层应力特征数值分析

西安地铁十号线穿越的泾阳—渭南断裂,该断裂为全新世活动断裂,黏滑发震与同震位错对地铁线路构成潜在安全威胁。为揭示泾阳—渭南断裂带黏滑发震和同震位错作用引起的场地形变与地层应力特征,以西安地铁十号线穿越泾阳—渭南断裂带为工程背景,建立断裂带场地同震位错与黏滑发震地质力学模型,考虑不同位错量及发震强度,开展断裂带场地形变及应力场特征的数值模拟分析。结果表明:同震位错下场地在断裂带附近上、下盘分别出现应力降低区和增强区,场地呈反“S”形差异沉降破坏,差异位移在断裂带处达到峰值且塑性区集中,上盘变形范围与塑性区分别为下盘的1.67倍和2.50倍;黏滑发震作用下场地在断裂带附近位移量及差异形变均达到峰值,大震时场地位移影响范围约为中震的6.50倍,且具有典型的上盘放大效应,远离断裂带时位移呈线性递减;大震时地表峰值加速度放大系数受影响范围为中震时1.14倍,场地呈“V”形剪切破坏,上盘塑性区范围约为中震时1.40倍,而下盘则为1.00倍。研究结果可为西安地铁线路穿越泾阳—渭南断裂带场地的抗震设防提供科学依据与参考借鉴。

十四运期间渭南市PM_(2.5)中无机元素来源解析及健康风险评估

利用Amms-100大气重金属分析仪在线数据,结合正交矩阵因子法(PMF)对渭南市在中华人民共和国第十四届运动会(十四运)期间细颗粒物(PM_(2.5))中的14种无机元素的污染特征及来源进行分析。结果表明,总元素的平均质量浓度十四运前(2.4μg/m^(3))>十四运后(2.2μg/m^(3))>十四运期间(1.3μg/m^(3))。表征扬尘的元素昼夜变幅在十四运期间远高于其他时段;铅(Pb)的峰值与交通早晚高峰时间一致,其日间变幅在中期较为平缓,表明十四运期间扬尘源和交通源的控制效果显著;钾(K)在夜间浓度较高可能与站点东北方向聚集的村庄生物质燃烧有关。PMF结果显示,监测期间渭南市PM_(2.5)中无机元素主要来源于扬尘源(45.2%)、燃烧源(34.5%)、交通源(12.0%)和工业源(8.3%)。健康风险评价模型结果显示,所有时段中不同来源的非致癌风险的危险商(HQ)均小于1,但在不同时段中锰(Mn)对儿童的HQ最高,且砷(As)对儿童存在致癌风险。

渭河盆地东南缘渭南塬前北侧分支断层的浅部结构及晚第四纪活动

渭南塬前断裂是渭河盆地东南缘一条重要的近EW向的全新世活动断裂,与1556年华县8级特大地震的发生密切相关。该断裂的北分支——渭南塬前北侧分支断层通过渭南市区,查明该北侧分支断层的展布、浅部结构、晚第四纪活动性以及发震能力,对于当地的防震减灾工作具有重要意义。文中通过浅层地震和钻孔联合剖面探测,结合地面地质调查,对渭南塬前北侧分支断层的展布、结构特征以及晚第四纪活动性开展研究。4条测线的浅层地震勘探揭示渭南塬前北侧分支断层与渭南塬前断裂平行展布,两者呈阶梯状正断层结构关系。渭南塬前北侧分支断层错断多套第四纪地层,显示出生长型正断层特征;可识别的上断点埋深为95m以浅,晚更新统的垂直错距为16~20m;在剖面上表现为宽200~1 800m的次级断陷带,具有阶梯状正断层和小型地堑结构。钻孔联合地质剖面揭示渭南塬前北侧分支断层距今19ka以来仍有活动,晚更新世中期以来的平均垂直运动速率为0.07~0.26mm/a。结合地表的断层陡坎和断错地貌现象判定,渭南塬前北侧分支断层与渭南塬前主断层同样具有较强的晚更新世—全新世活动性,不能排除渭南塬前北侧分支断层曾经参与1556年华县8级大地震破裂的可能性,亟需针对其潜在地震危险性和危害性开展相关研究。
