Research of the Conductive Structure of Crust and the Upper Mantle beneath the South-Central Tibetan Plateau

With the super-wide band magnetoteiluric sounding data of the JUong （吉隆）-Cuoqin （措勤） profile （named line 800） which was completed in 2001 and the Dingri （定日）-Cuomai （措迈） profile （named line 900） which was completed in 2004, we obtained the strike direction of each MT station by strike analysis, then traced profiles that were perpendicular to the main strike direction, and finally obtained the resistivity model of each profile by nonlinear conjugate gradients （NLCG） inversion. With these two models, we described the resistivity structure features of the crust and the upper mantle of the center-southern Tibetan plateau and its relationship with Yalung Tsangpo suture： the upper crust of the research area is a resistive layer with resistivity value range of 200-3 000 Ω.m. The depth of its bottom surface is about 15-20 km generally, but the bottom surface of resistive layer is deeper in the middle of these two profiles. At llne 900, it is about 30 km deep, and even at line 800, it is about 38 km deep. There is a gradient belt of resistivity at the depth of 15-45 km, and a conductive layer is beneath it with resistivity even less than 5 Ω.m. This conductive layer is composed of individual conductive bodies, and at the south of the Yalung Tsangpo suture, the conductive bodies are smaller with thickness about 10 km and lean to the north slightly. However, at the north of the Yalung Tsangpo suture, the conductive bodies are larger with thickness about 30 km and also lean to the north slightly. Relatively, the conductive bodies of line 900 are thinner than those of line 800, and the depth of the bottom surface of line 900 is also shallower. At last, after analyzing the effect factors to the resistivity of rocks, it was concluded that the very conductive layer was caused by partial melt or connective water in rocks. It suggests that the middle and lower crust of the center-southern Tibetan plateau is very thick, hot, flabby, and waxy.

Heat Budget of the South-Central Equatorial Pacific in CMIP3 Models

ABSTRACT Using data from 17 coupled models and nine sets of corresponding Atmospheric Model Intercomparison Project （AMIP） results, we investigated annual and seasonal variation biases in the upper 50 m of the south-central equatorial Pacific, with a focus on the double-ITCZ bias, and examined the causes for the amplitude biases by using heat budget analysis. The results showed that, in the research region, most of the models simulate SSTs that are higher than or similar to observed. The simulated seasonal phase is close to that observed, but the amplitudes of more than half of the model results are larger than or equal to observations. Heat budget analysis demonstrated that strong shortwave radiation in individual atmospheric models is the main factor that leads to high SST values and that weak southward cold advection is an important mechanism for maintaining a high SST. For seasonal circulation, large surface shortwave radiation amplitudes cause large SST amplitudes.

Exploratory Potential for Gold Placer Deposits in the Coastal Range, BioBío Region, South-Central Chile

Many gold placers located in the Coastal Range of south-central Chile have been exploited commercially during the past decades;nevertheless and until now, there are not any exploration studies of these placers and their basement. In order to provide an overview of exploratory potential, the stream sediments that are part of several gold placers in the northwest area of the BioBío region are analyzed, which have been registered on the basis of empirical evidence from artisanal mining activities. The overview consists of two goals: 1) determine the presence of auriferous occurrences (stream sediments and basement) and 2) identify potentially favorable areas to find gold placer deposits. Through optical microscopy this study characterized the metallic and non-metallic mineralogy of the basement, along with geochemical analyses of stream sediments and surrounding rocks of the placer deposits. The geochemical results show two sectors with high precious metal contents in sediments (up to 24 ppm of Au and 8 ppm of Ag) and two rocky outcrops with Au (757 and 41 ppb). Additionally, there are depressions in the study area that have received large amounts of sediments (reaching up to 170 m-thick), which are favorable places for the accumulation of auriferous sediments from nearby valleys due to the tectonic and structural conditions where they are located. Then, these results show an exploratory potential for gold placers and can be useful to delineate future exploration strategies in the Coastal Range of south-central Chile.

Mineralogy of a Radioactive-Rare Earth Elements Occurrence in the Paleozoic Batholith, South-Central Chile

South-central Chile has some potential mineral resources including radioactive and rare earth elements (REE) minerals. This study reports some basic characteristics of the mineralogy of a radioactive-rare earth elements occurrence, related to a pegmatitic outcrop “Vertientes Pegmatite” hosted on Paleozoic granitic rocks of the South Coastal Batholith and discusses potential areas for REE deposits, particularly beach placers along the coastline of the BioBío region. In this pegmatite, X-ray diffraction analysis shows uranium-bearing minerals such as coffinite and metaschoepite, along with microcline, anorthoclase, albite, quartz and illite. Through optical microscopy and electron probe micro-analyzer (EPMA), rare earth minerals (monazite and xenotime) and radioactive minerals (thorite and thorium silicate ± uranium) were identified. Additionally, granitic rocks of the South Coastal Batholith around this pegmatite show rare earth minerals (monazite and allanite).

京津冀高质量协同:发展历程、取得成效与未来展望

京津冀协同发展是重大国家战略。经过10年来的发展,京津冀协同发展已迈入高质量协同发展阶段,在科技创新、空间布局、生态保护、对外开放、民生领域等方面取得一系列显著成效,但也存在创新转化能力不足、产业转移承接断层、“过密过疏”现象突出、生态联合治理及生态补偿机制有待完善等挑战。面向中国式现代化建设的先行区、示范区这一目标任务,应进一步完善顶层制度设计和空间功能布局,以新质生产力为协同发展的新引擎,让数据要素成为协同发展的新动能,推动京津冀协同发展迈向更高质量、更高水平。

京津冀协同发展战略实施十年回顾及展望

京津冀协同发展战略实施近十年来,北京非首都功能疏解取得明显成效,北京城市副中心和雄安新区“两翼”建设稳步推进,三地交通一体化、生态联防联控、产业转型升级三大领域取得率先突破,区域内体制机制改革与创新稳步实施。但仍面临经济份额下降、创新驱动经济增长能力不强、人口和经济过密与过疏现象并存等问题。展望未来,应从现代化首都都市圈建设、打造“一核两翼”空间新格局、优化区域现代产业分工体系与区域创新格局、创新跨区域协同治理体制机制等方面,全面推进京津冀协同发展迈向更高水平、更优效益和更高质量,努力使京津冀成为中国式现代化建设的先行区、示范区。

京津冀地区大气污染物与二氧化碳的协同减排分析

推进减污降碳协同增效成为社会经济高质量发展的客观要求。基于协同控制效应坐标系、单指标协同减排弹性和协同减排协同度等多维度协同减排分析方法,对2013—2019年京津冀地区CO_(2)排放量与SO_(2)、NO_(x)、烟粉尘的排放特征和协同减排水平进行综合评价。结果表明:(1)近年来,京津冀地区的CO_(2)排放量整体上处于增长的平台期,三类大气污染物(SO_(2)、NO_(x)、烟粉尘)实现了不同程度的减排,然而与全国对比,京津冀地区减污降碳协同增效工作仍面临较大压力。(2)京津冀地区CO_(2)与SO_(2)、NO_(x)和烟粉尘三类大气污染物之间存在不连续的协同减排年份、不稳定的协同减排交叉弹性、中低程度的耦合协同度,反映了该区域协同减排程度均处于较低水平,尚未形成稳定的减污降碳协同增效状态。在绿色低碳高质量发展目标引领下,提出如下建议:(1)加快推动污染末端治理向源头治理转变,从源头上实现产业发展和能源消费的低碳化。(2)将产业结构优化作为推进京津冀减污降碳的主要途径,统筹规划项目布局和产能分配。(3)发展能源替代和节能减排,优化调整京津冀的能源消费结构。

京津冀协同发展政策对人口增长态势的影响——基于系统动力学模型的研究

在京津冀协同发展背景下,流动人口集聚态势变化将使不同区域的人口规模与结构发生变动。应用系统动力学模型不仅可以模拟社会经济因素对人口增长产生的影响,还可以模拟政策效应,分析不同政策方案对京津冀人口增长态势的影响。模型不仅纳入了人口、经济与资源环境子系统的众多参数,厘清了京津冀协同发展过程中系统内要素的反馈过程,还依据北京疏解产业产值比衡量疏解政策强度并设计了政策参数,模拟了高方案、中方案、低方案以及技术进步方案下京津冀的人口增长趋势。应用灵敏度检验验证了模型的稳健性。结果显示,不同政策方案下人口规模与结构的变动呈现出明显差异。具体而言,政策实施后随着产业转移与区域内劳动力集聚态势变化,北京未来常住人口规模将下降,这可以缓解城市的资源承载压力;天津、河北的劳动力供给则有所增加。在人口结构方面,政策实施后北京的人口老龄化水平将提高,天津、河北的人口老龄水平虽然在中期会降低,但是在远期则会提高。京津冀协同发展政策、技术进步与市场机制共同发挥作用,可以有效地调节城市人口增长。文章的政策含义是,京津冀各地应依据人口增长的趋势实施差异化、动态化的政策,不断提升资源环境承载能力,以实现区域人口合理分布、经济发展、生态安全的目标。

“公转铁”政策对京津冀绿色物流效率的影响

为落实绿色发展理念,促进京津冀物流业高质量发展,有效发挥“公转铁”政策对绿色物流效率的提升效应,在系统梳理“公转铁”政策促进绿色物流效率理论机制的基础上,用2010—2020年京津冀地区面板数据,通过双重差分模型、广义双重差分模型和中介效应模型,研究“公转铁”政策对绿色物流效率的促进效应以及作用机制。研究发现,“公转铁”政策在京津冀地区的实施对提升绿色物流效率具有显著的促进效应,并且该效应在经过稳健性检验后依旧成立;政策实施力度对绿色物流效率存在显著的影响,绿色物流效率随着政策实施力度增强而不断提升;“公转铁”政策通过改变物流企业的运输方式偏好,增强铁路运输对公路运输的替代作用,提升绿色物流效率;绿色物流效率提升还受到铁路设施水平、区域建设水平、经济水平、创新能力等多种因素的影响。因此,京津冀绿色物流效率提升,应该考虑多种因素的综合影响,以多层次和系统性支撑政策推动“公转铁”政策的实施;以改变承担社会物流活动企业运输偏好为导向;充分考虑当地内外部环境,结合产业结构、创新能力等因素调整“公转铁”政策实施力度。

京津冀城市群综合承灾能力时空异质性研究

基于2010—2020年京津冀城市群13个城市的调查数据,应用Kernel密度估计方法、空间自相关模型及Dagum基尼系数,分析不同时期京津冀城市群综合承灾能力时空动态演进分布格局及地区差异。结果表明:(1)在时间维度,2010—2020年京津冀城市群综合承灾能力总体呈现逐渐上升趋势,但京津冀城市群各市之间的承灾能力水平差距逐渐增大,区域整体呈现非均衡特征;(2)在空间维度,2010—2020年京津冀城市群综合承灾能力在空间分布上关联度较低,不存在显著的集聚或分散特征,但有局部地区产生聚集特点,属于“高-高”“低-低”空间聚集型城市较多,在此期间京津冀城市群综合承灾能力呈现空间集聚与空间分异并存;(3)京津冀城市群综合承灾能力的总体差异呈现上升趋势,北京-河北地区间差异最大,地区间差异是总体差异的主要来源。掌握京津冀城市群综合承灾能力的时空分布变化规律,并制订相应的防灾策略是京津冀城市群有效应对外部冲击以及实现京津冀地区协同与高质量发展国家战略的重要支撑。

京津冀协同发展战略的空间结构评估与政策优化

“一核双城三轴四区多节点”是京津冀协同发展战略的重要空间支撑。2014年以来,京津冀城市群空间形态结构初步形成,“一核”中心性短期上升,“双城”融合趋势明显,京津发展轴逐渐向“菱形”城市化区域拓展。但从功能结构来看,北京的核心辐射带动能力还有待提升,北京与天津差距持续拉大,“三轴”的产业与人口集聚力尚需增强,“四区”的协调度和多节点综合承载力也有待完善。整体来看,京津冀城市群的空间结构尚停留在形态建设层面,空间功能还有待进一步发挥。未来,应形成“一主两副、三圈耦合、四轴四区、多中心”的空间结构,把石家庄建设成为京津冀的副中心,促进京津冀三大都市圈耦合协同,将“三轴”拓展为“四轴”,大力培育具有“二传手”功能的区域性中心城市,支撑京津冀协同发展战略长期目标的实现。

京津冀科技创新与产业协同发展研究
