Planning and construction of Xiong’an New Area(city of over 5 million people):Contributions of China’s geologists and urban geology

China established Xiong’an New Area in Hebei Province in 2017,which is planned to accommodate about 5 million people,aiming to relieve Beijing City of the functions non-essential to its role as China’s capital and to expedite the coordinated development of the Beijing-Tianjin-Hebei region.From 2017 to 2021,the China Geological Survey(CGS)took the lead in multi-factor urban geological surveys involving space,resources,environments,and disasters according to the general requirements of“global vision,international standards,distinctive Chinese features,and future-oriented goals”in Xiong’an New Area,identifying the engineering geologic conditions and geologic environmental challenges of this area.The achievements also include a 3D engineering geological structure model for the whole area,along with“one city proper and five clusters”,insights into the ecology and the background endowment of natural resources like land,geothermal resources,groundwater,and wetland of the area before engineering construction,a comprehensive monitoring network of resources and environments in the area,and the“Transparent Xiong’an”geological information platform that is open,shared,dynamically updated,and three-dimensionally visualized.China’s geologists and urban geology have played a significant role in the urban planning and construction of Xiong’an New Area,providing whole-process geological solutions for urban planning,construction,operation and management.The future urban construction of Xiong’an New Area will necessitate the theoretical and technical support of earth system science(ESS)from various aspects,and the purpose is to enhance the resilience of the new type of city and to provide support for the green,low-carbon,and sustainable development of this area.

Influence of underground space development mode on the groundwater flow field in Xiong’an new area

The degree and scale of underground space development are growing with the continuous advancement of urbanization in China.The lack of research on the change of the groundwater flow field before and after the development of underground space has led to various problems in the process of underground space development and operation.This paper took the key development zone of the Xiong’an New Area as the study area,and used the Groundwater modeling system software(GMS)to analyse the influence on the groundwater flow field under the point,line,and surface development modes.The main results showed that the underground space development would lead to the expansion and deepening of the cone of depression in the aquifer.The groundwater level on the upstream face of the underground structure would rise,while the water level on the downstream face would drop.The“line”concurrent development has the least impact on the groundwater flow field,and the maximum rise of water level on the upstream side of the underground structure is expected to be approximately 3.05 m.The“surface”development has the greatest impact on the groundwater flow field,and the maximum rise of water level is expected to be 7.17 m.

Hydrogeochemical characteristics of groundwater and pore-water and the paleoenvironmental evolution in the past 3.10 Ma in the Xiong’an New Area,North China

The groundwater level has been continuously decreasing due to climate change and long-time overexploitation in the Xiong’an New Area,North China,which caused the enhanced mixing of groundwater in different aquifers and significant changes in regional groundwater chemistry characteristics.In this study,groundwater and sediment pore-water in drilling cores obtained from a 600 m borehole were investigated to evaluate hydrogeochemical processes in shallow and deep aquifers and paleo-environmental evolution in the past ca.3.10 Ma.Results showed that there was no obvious change overall in chemical composition along the direction of groundwater runoff,but different hydrochemical processes occurred in shallow and deep groundwater in the vertical direction.Shallow groundwater(<150 m)in the Xiong’an New Area was characterized by high salinity(TDS>1000 mg/L)and high concentrations of Mn and Fe,while deep groundwater had better water quality with lower salinity.The high TDS values mostly occurred in aquifers with depth<70 m and>500 m below land surface.Water isotopes showed that aquifer pore-water mostly originated from meteoric water under the influence of evaporation,and aquitard pore-water belonged to Paleo meteoric water.In addition,the evolution of the paleoclimate since 3.10 Ma BP was reconstructed,and four climate periods were determined by theδ18O profiles of pore-water and sporopollen records from sediments at different depths.It can be inferred that the Quaternary Pleistocene(0.78‒2.58 Ma BP)was dominated by the cold and dry climate of the glacial period,with three interglacial intervals of warm and humid climate.What’s more,this study demonstrates the possibilities of the applications of pore-water on the hydrogeochemical study and further supports the finding that pore-water could retain the feature of paleo-sedimentary water.

Land Subsidence in Xiong’an New Area,China Revealed by InSAR Observations

In 2017,China’s central government approved the national strategy to build Xiong’an New Area(XNA,100 km southwest to Beijing),which was announced as a"millennium strategy"and a"demo area"for a sustainable,modern,and innovative urban model.Xiong’an will draw in as much as$380 billion investment and is expected to help accelerate the development of the wider Beijing-Tianjin-Hebei(Jingjinji)Area.In this paper,present subsidence in the XNA area is investigated using InSAR observations for the first time.The 24 SAR images acquired by European Space Agency’s Sentinel-1 satellites during the period from June 2017 to July 2018 suggest that in the north of Xiong County,the subsidence rate reaches up to 90 mm/y,which is highly correlated with the exploitation of geothermal drilling.As the construction in the XNA area will significantly accelerate and its high-quality development,the InSAR findings could provide valuable information for future sustainable urban planning and underground infrastructure construction.

The Importance of Environmental English Public Signs to Xiong’an New Area’s Ecological Environment in China

With the establishment and development of Xiong’an New Area in China, more foreign industries and visitors will be attracted to come here. Investigations made in our study show that the environmental English public signs are very important. They can offer directions for foreigners who can’t understand Chinese well because they have these three functions: indication, suggestion and prohibition. In order to help Xiong’an New Area play its “eco card”, the translators are supposed to attach great importance to the translation of environmental English public signs.

Analysis of Air Pollutants in Xiong’an New Area Based on MATLAB Grey Model

The purpose of this paper is to study the air pollutants in Xiong’an New Area based on MATLAB grey model [1]. From 2011 to 2016, the results of sulfur dioxide (SO2), nitrogen dioxide (NO2) and inhalable particulate matter (PM1O) detected at monitoring points in the three counties of Xiong’an were analyzed. According to the national environmental air quality standard [2], the air quality in Xiong’an New Area was reasonably evaluated based on grey model in MATLAB. Judging from the weight of pollution factors in the model, sulfur dioxide (SO2) is the controlling factor of air quality in Xiong’an New Area, and the weight of nitrogen dioxide (NO2) gradually increases. The main sources of the three pollutants were obtained by comprehensive data analysis, and a grey model was established according to the mass concentration of the main air pollutants, and the grey forecasting model was tested. The experimental results show that the model can be effectively applied to the forecasting of ambient air quality. On this basis, the present situation of atmospheric environmental quality in Xiong’an New Area and suggestions for improvement are obtained.

抗日根据地“新式家庭”的历史建构——以太行区李来成家庭为中心

20世纪40年代,为了动员群众以便更好地开展大生产运动,中国共产党结合晚清尤其是新文化运动以来知识分子家庭革命观与马克思主义妇女解放理论,对根据地家庭问题进行了理论探索与实践创新。于是,太行区襄垣县李来成家庭作为“新式家庭”的典型应时代发展需求而生,其特点在于提倡民主家风、制订生产节约计划以及建立相关激励机制。通过主流媒体宣传与文娱宣传,该家庭模式从太行区推广到各抗日根据地,在建构“新民主主义”革命话语、开展农业社会主义改造、推动农村妇女解放乃至建设社会主义精神文明等方面产生了深远影响。尽管李来成家庭在1945年以后逐渐淡出媒体,但其为中国进行农村家庭变革以及建构农民集体主义理念提供了重要历史借鉴。

论长寿内卷化

进入长寿时代后,农村老年人在其高龄阶段的生命历程中,会遭遇各种负性生活事件。伴随其机体衰退,他们会不可避免地坠入巨大的生活风险之中。结合中国传统的老龄观,通过对“内卷化”这一概念的辨析和创造性转化,可以构建“长寿内卷化”的概念,以理解当前农村高龄老年人的生活风险状态。当高龄老年人的生命历程步入内卷点之后,其寿命虽然仍然在延长,但由于各种负性生命事件的发生和影响,生命质量却开始下滑,与理想状态相反的是,这段生命历程将持续进入病寿、苦寿、辱寿等单一存在或同时并存的生活风险状态;当这一曲线下滑至接近生命质量轴的交叉点时,它意味着高龄老年人生命主动或被动的终结。支撑从长寿内卷化到生活风险发生的机制是,城镇化进程带来的社会压力通过环状结构的新家庭结构形式向高龄老年人转移。秉持积极老龄观,加强政策干预,实现长寿去内卷化,是长寿时代所必需面对的重要议题。作为一个分析性概念的“长寿内卷化”,不仅对理解当前农村高龄老年人的生活风险具有理论意义和政策意义,将来也同样适用于分析城市高龄老年人的生活风险状况。
