Topic: Towards Global Carbon Neutrality: Inspiration from Comprehensive Surveys on Tibetan Plateau and Adjacent Regions

Abstract: In-depth understanding mechanism of global climate change is critical to achieving global carbon neutrality in the near future. The continuous convergence between Indian and Asian continents has created a growing Tibetan plateau. Rough 7 trillion tones atmospheric CO2 were transformed as organic carbon, carbonates and carbonic magmas/fluids trapped in the Tibetan thickened crust and adjacent foreland basins, leading to glacial-interglacial climate. During the interglacial periods, the Tibetan plateau is a huge heat source, together with higher sea surface temperature, resulting in much freshwater being removed to low latitudes including the Tibet plateau. Tibet plateau thus becomes a greenly giant water tower and sequesters huge amounts of CO2 through tectonics and plants to decline global atmospheric CO2 concentrations greatly. During the glacial times, the Tibetan plateau is a hugely cold source that much freshwater is sent to high latitudes, e.g., transformed as ice sheets in Greenland island. The low latitudes thus become deserts. The deserted plateau releases, rather than absorb, large amounts of CO2, resulting in global atmospheric CO2 concentrations never below 180 ppmv and rising subsequently. Tibetan plateau has thus remained a quasi-dynamic balance of globally atmospheric CO2 concentrations since the Miocene times. Today much freshwater is returning to inland deserted regions, especially the deserted Tibetan plateau, due to global warming triggered off by anthropic emissions. Large amounts of atmospheric CO2 and much water are sent to Tibetan deeply broken silicates by the tectonics and plant roots, enhancing subsurface silicate chemical weathering continuously. Pedogenic carbonates and organic carbon are also continuously formed in the wetlands. These processes are always carbon unsaturation so that at least 10 billion tons/year atmospheric CO2 are passively sequestered by the Tibetan plateau and adjacent regions in the near future based on our conservative estimates. Therefore, man-made planting wetland within Tibetan and adjacent regions is a better approach to achieve global carbon neutrality in the near future.

Topic: Water Leak Control for the Oil-producing Wells Using Downhole Water Sink Technology

Abstract: Casing or tubing leaks cause unwanted water production from oil-producing wells. Many chemical and mechanic water control technologies can be used to solve this problem, including squeezing chemical shutoff fluids into the targeted zone or using plugs, cement, packers, patches to block the leakage. Although those methods are field-proven to be effective, the mechanical solutions may require well logs to detect the water entry point in the well. Chemical methods may present environment risks. In this study, an alternative method, Downhole Water Sink, is proposed to solve the problem of unwanted water production from a casing or tubing leak. The effectiveness of this method to control water production in a well with casing or tubing leaks is tested using the Hele-Shaw experimental model. The results show that this method can control unwanted water production via dynamic control of the pressure drawdown in the reservoir. From a technical standpoint, the advantage of this technology is that it eliminates the need to run logs to locate the water entry point and does not require chemical injection into the formation. From an environmental standpoint, this technology has the circular economy elements. Because the produced water in this technology contains little or no oil, it can be reused for reinjection into the reservoir for water flooding or pressure maintenance purposes. Therefore, a production-reinjection process to recycle the produced water is established to reduce the pollution caused by discharging the wastewater into the environment.

Topic: Spatial Quantitative Analysis of Urban Energy Consumption Based on Night-Time Remote Sensing Data and POI

Abstract: Climate change has become a major global environmental issue that is widely concerned by countries around the world. It has been a very clear scientific consensus that the global carbon emission has to be cut urgently under the context of the global warming and extreme climate. Currently, few studies on the urban energy consumption have been performed, especially the quantitative research on the scale of urban blocks, which is actually required by cities in order to adopt precise control, optimize energy structure, and reduce carbon emissions. This paper took Jingmen, a resource-based city, as a case city, and applied night-time remote sensing data, POI, and other big data. Quantitative analysis of the spatial data on key factors affecting carbon emissions in transportation, industry, and construction sectors, respectively, was applied to realize block- scale spatial visualization of urban energy consumption, and furthermore, to discuss the impact of urbanization and industrialization on urban energy consumption. It is found that the continuous growth of energy consumption in the industrial sector was the main driving factor of the city's total energy consumption growth. Among the 72 towns (blocks), 10 towns (blocks) were dominated by industrial energy consumption which accounted for up to 68% the energy consumption of Jingmen. From 2005 to 2015, the total energy consumption of Jingmen City increased by 828,200 tons of standard coal equivalent(tce), while the number of towns (blocks) with more than 10,000 tons of standard coal equivalent(tce) decreased by 4. Therefore, the energy consumption of Jingmen City showed a trend of increase and concentration. The conclusions of this study can fill up the problems that cannot be found in the energy consumption statistics of cities, and propose a more accurate way to reduce energy consumption in Jingmen City, which provide a reference for the green transformation of similar small and medium-sized resource-based cities.

Topic: Nitrogen Management by Livestock Manure Application in the Integrated Crop-livestock System(ICLS)

Abstract: Nitrogen(N) and phosphorus(P) pollution is common problem worldwide. Global N and P cycle is reshaped by human activities, especially through agricultural production. The first pollution survey in China estimated that 57% of nitrogen (N) and 67% of phosphate (P) in water bodies were from agricultural production losses. The UN Food and Agriculture Organization has listed intensive livestock and poultry farming as one of the three major sources of environmental pollution in the world. It was estimated that 551 million tons of manure (dry weight base) were generated in 2014, which contained 25.3 million tons of N, 5.2 million tons of P, and 19.4 million tons of potassium, respectively. And trend will increase even further with the expansion of the livestock and poultry breeding industry. In this speech, Professor Zhang Qingwen will introduce some researches of her team considering identification of key points in N flows in China's agricultural system using NUFER model, and the potential of crop-livestock system coupling based on land bearing capacity of cropland. Besides, the results of field experiment on gaseous nitrogen loss control and optimized nitrogen management under ICLS showed that combined application of biogas slurry and synthetic fertilizer could potentially reduce N2O emission and increased crop yield. N management by livestock manure application in the integrated crop-livestock system(ICLS) can provide a scientific reference for achieving green and high-quality development of agriculture.

Topic: Research on the Upper Atmospheric Gravity Wave Parameters at the Altitude of 90-100 km Detected by GBAII

Abstract: In the upper atmospheric radioactive transfer, the AGWs (atmospheric gravity waves) come from the Earth’s surface physical phenomenon upward propagating. AGWs are reflected by the variation of the upper atmospheric concentration and wind velocity. AGWs play an important role in the dynamics of the upper and middle atmosphere. In this topic, the three number densities of O2 nightglow species at the peak altitude of 94 km at Xi'an had obtained through the self-made GBAII (Ground-based airglow imaging interferometer) prototype which could obtain the O2 (0-1) nightglow’s imaging interference fringes at the three local times in June.13 2012, Oct.18, 2018, and April.7 2019. And three corresponding AGWs parameters of the periods, 2 dimension wavelengths, energy flux, and momentum flux were obtained by GBAII, respectively: AGWs’ period ranges from 0.32 h to 7.05h; the meridional wavelengths range from 30.53 km to 494.90km and the zonal one ranges from 28.22 km to 610.89km; the energy flux of AGWs ranges from 0.0605m3s-3 to 60.6554m3s-3 and the momentum flux ranges from 0.0017m2s-2 to 1.5788m2s-2. The research results can provide some scarce data for O2 concentration in the upper atmosphere and related wave parameters of AGWs.
