基于新生代活动构造背景的地震重点危险区域综合研究——以安徽为例

基于地震的发生与断裂的活动性密切相关,为了科学合理并尽可能准确地判定未来地震重点危险区域,以安徽为例,利用由深浅部对比、宏微观构造解析所给出的新生代构造活动性最新研究成果,结合地震活动性资料研究结果,对一些重点部位的地震危险性进行了综合研究。结果表明,根据长时间尺度的地质构造最新研究揭示的活动性较强区域,与根据近代地震活动性资料研究反映的危险性较大区域,呈现较好的一致性特征,从而为未来地震重点危险区域的判定提供了新的较为可靠的依据和方法。     

Application research of narrow band Internet of things buoy and surface hydrodynamics monitoring

This paper applies the narrow band Internet of things communication technology to develop a wireless network equipment and communication system, which can quickly set up a network with a radius of 100 km on water surface. A disposable micro buoy based on narrow-band Internet of things and Beidou positioning function is also developed and used to collect surface hydrodynamic data online. In addition, a web-based public service platform is designed for the analysis and visualization of the data collected by buoys. Combined with the satellite remote sensing data, the study carries a series of marine experiments and studies such as sediment deposition tracking and garbage floating tracking.     

Function of spa development in countryside for domestic tourism in China

The common problems on tourism of developing countries have often been researched by west researchers until now, which can be concluded into special words: “two sectors”, “enclave construction”, “government’s interference”, “developing scale”, and “the industrial role of tourism” etc. In fact all the researches were done from the areas with the patronage of foreign visitors, how is the situation of domestic tourism was ignored in some points. In this paper, another developing model compared with the one with foreign visitors was presented to the readers on the case studies of countryside spas in China. Through this research, one aspect of Chinese real leisure life can be understood to some extent, and the implying that for bigger developing countries the domestic tourism can match the effect of international tourism should not be ignored at least to China. As the developing of economy, domestic tourism will finally unite with international one together, and the common problems will disappear step by step, therefore domestic tourism and international tourism of developing countries should be researched equally since now. Biography: WANG Yan-ping (1962–), male, a native of Heilongjiang Province, is a doctorate student of Chiba University of Japan. His research insterest is environmental impact assessment.

基于细粒岩石类型对玛湖凹陷下二叠统风城组烃源岩分类评价

准噶尔盆地玛湖凹陷风城组页岩油勘探取得巨大突破,但是按照普遍认可的页岩油烃源岩评价标准,本区的烃源岩品质并不理想。为了科学评价玛湖凹陷烃源岩品质特征,本文在系统的岩心观察和有机地球化学分析的基础上,揭示烃源岩的形成环境,并按照矿物组成对烃源岩分类评价。玛湖凹陷风城组细粒岩主要沉积于正常半深湖、咸化半深湖、半咸化半深湖、含热液半深湖和滨浅湖环境中,各环境中细粒岩的有机质特征存在一定区别,其中半咸化半深湖有机质较为富集,w(TOC)均值在1%左右。进一步结合有机质类型判别图解,表明咸化半深湖和含热液半深湖有机质来源以湖泊生物为主,而其他环境中存在湖泊和陆源混合有机质来源。基于有机质生烃潜力评价和成熟度(V_re=0.74%)估算,表明目前风城组烃源岩中有机质正处于大量排烃的成熟阶段,且确定了细粒岩中的烃类为原生烃。由于不同矿物组成的烃源岩吸附能力的差异,按照陆相泥质烃源岩和碳酸盐质烃源岩开展分类评价,结果表明风城组沉积了累计厚度近250 m的的有效烃源岩,且富含以藻类体为主的有机质。     

地基微波辐射计探测在黄河上游人工增雨中的应用

利用2003、2004年夏秋季在青海省河南县的地基双频段微波辐射计连续观测资料,在实施系统探测实验以进行辐射亮温值(TB(23.87),TB(31.65))与大气汽态总水汽含量(Q)和云中积分液态水含量(L)值反演处理的基础上,分析了黄河上游河曲地区的云水特征,并进行了降水预测及人工增雨作业指标的探讨。结果表明:在黄河上游河曲地区,7—9月纯晴天无云天气条件下,L值基本为0,表明了统计回归反演的显著性。多云条件下Q值和L值分别在3.76~4.75g·cm-2、227.34~859.42g·m-2的范围内。可降水云天气,Q值在5.23~8.65g·cm-2间,L值在421.18~1016.37g·m-2的范围内;积雨云个例分析表明,在降雨开始前近5小时的降雨酝酿期内,Q及L的增加有明显的波动,但在对流云出现并发展时,Q和L总是急剧上升,在降雨前达到一峰值;由河南站和西安站的Q、L值比较差异可以看出,Q、L值受水汽输送、地形等因素的影响,黄河上游河曲地区的人工增雨潜力有显著的优势;所计算出的降水预测阈值,可作为该地区人工增雨作业指标的参考。     

基于GIS技术的三江平原热量资源评价

基于GIS技术,使用黑龙江省气象观测站和农垦、森工系统观测站的气温资料,以及数字高程模型(DEM)资料,运用趋势面分析法和线性内插法得到三江平原栅格化的热量资源数据。分析表明,三江平原纬度和高度因子对各项热量指标分布均有影响,经度因子主要影响年平均气温、4月平均气温、7月平均气温、≥0℃积温和≥10℃积温;佳木斯西部、双鸭山西部、鸡西大部热量资源较丰富,而青黑山、完达山、老爷岭和太平岭等地区热量资源相对较差。分析结果为合理开发利用三江平原热量资源提供了依据。     

东海西湖凹陷早第三纪烃源岩生烃组分剖析

采用有机岩石学分析方法，结合有机地球化学资料，剖析了东海盆地西湖凹陷早第三纪烃源岩。该烃源岩富镜质组，贫惰性组，含一定数量的壳质组和腐泥组（１０％～３０％）。壳质组＋腐泥组含量与氯仿沥青、总烃和有效碳等参数密切正相关；树脂体和孢子体＋藻类体分别是早期生烃和晚期生烃的重要组分。在此基础上提出了西湖凹陷烃源岩的生烃模式。     

Pretreatment of high strength waste emulsions by combined vibratory shear enhanced process with Fenton oxidation

Pretreatment of waste emulsions with high organic content by a combined process of vibratory shear enhanced process and Fenton’s oxidation prior to biological treatment was investigated. Vibrating membrane had shown good performance in chemical oxygen demand and oil removals and the mitigation of concentration polarization. However, the permeate after filtration processing still contained high content of organics. Thus, additional Fenton oxidation was applied to reduce the organic loading, and improve the biodegradability of the wastewater. The optimal molar ratio of ferrous iron to hydrogen peroxide was 0.05 obtained from the jar-test experiments. Removal of organics was enhanced by increasing hydrogen peroxide dosage, while efficiency of hydrogen peroxide reached maximum of 1.11(w/w) at the hydrogen peroxide dosage of 6.8 g/L. Furthermore, the biological experiments indicated that the high concentration of organics could inhibit microbial activity, which decreased the chemical oxygen demand degradation rates. The adaptive period of the microbe was greatly shortened using Fenton’s reagent at the low dosages. The improvement of the biodegradability could be explained by partial mineralization and chemical transformation of parent organic compounds after Fenton oxidation.
