数字技术在当代备受青睐,成为政府进行社会治理的重要工具。然而,在数字治理中,政府数字权力在无形地滋长和扩张,也产生了侵蚀公民权利保障基础的负外部性。因此,要建立起必要的权力监督体系。但是,我国法律建构的内部监督机制还存在存而不用的状态,公民通过行政诉讼等途径维护自身合法权利也遇到重重阻碍。内外部监督机制的困境,源于数治和法治之间存在内在张力,工具理性和价值理性存在冲突。传统的法律治理技术需要结合数字时代的新发展做出必要的变革。在建构权力控制体系时,需要结合数据的性质、数字权力的运行逻辑,构建宏观与微观相结合、内部监督与外部监督相衔接、主观诉讼与客观诉讼并行的控制体系。

Comparative Analysis of Ambient Ozone and Its Background Concentration in Beijing in Recent Years

Huanjing Kexue/Environmental Science 2025年第3期46卷 1275-1284页

作者： Li, Yun-Feng Tang, Ji-Lin Ji, Yuan-Yuan Wang, Ya-Fei Li, Hong gao, rui Department of Environmental Engineering School of Mechanical Engineering Beijing Institute of Petrochemical Technology Beijing102617 China State Key Laboratory of Environmental Criteria and Risk Assessment Chinese Research Academy of Environmental Sciences Beijing100012 China

To understand the trends of O3 pollution changes and the contribution of regional background in Beijing in recent years，this study investigated the temporal variations of O3 mixing ratios and the exceedance of O3pollution at different types of sites，such as urban，suburban，clean，regional，and transportation sites，based on the online monitoring data from 34 stations in Beijing from 2018 to 2022. The regional background estimation method proposed by the Texas Commission on Environmental Quality（TCEQ）was applied to calculate the contributions of regional background and local generation to O3. The results showed that the annual average value of O3 mixing ratios in Beijing was the highest in 2019，the lowest in 2021，and rebounded in 2022，from 2018 to 2022. Except for transportation sites，O3 mixing ratios in Beijing and all other types of sites exhibited decreasing trends. The highest monthly average value of O3 occurred in June and the monthly average values of clean sites were often higher than those of other sites. The proportions of O3 exceedance days and heavily polluted days varied over the last five years and days with high O3 pollution more often occurred at the clean site. The O3 exceedance days were mostly dominated by light pollution and the average O3 mixing ratios on heavily polluted days in 2020-2022 were greater than those in 2019. To exclude the influence of NO on the"titration"effect of O3，the TCEQ method was estimated by using the total oxidant Ox（Ox=O3+NO2）instead of O3. The results showed that both the regional background and the local generation in Beijing showed decreasing trends and the contribution of the regional background was significantly higher than that of the local generation. However，the contribution of the regional background decreased in the summer due to the enhancement of the photochemical activities. In general，although the O3 mixing ratios in Beijing had been decreasing from 2018 to 2022，no such trend was observed in the O3 mixing ratios
