Identifying priority areas of Four Major Chinese carps’ species in the Pearl River basin based on the MaxEnt model

Watershed Ecology and the Environment 2023年第1期5卷 18-23页

作者： Shao, Xiaojing Liu, Xing Cai, Jie Cai, Yanzi Cui, Baoshan Research Center for Monitoring and Environmental Sciences Taihu Basin & East China Sea Ecological Environment Supervision and Administration Authority Ministry of Ecology and Environment of the People's Republic of China Shanghai 200125 China State Key Joint Laboratory of Environmental Simulation and Pollution Control School of Environment Beijing Normal University Beijing 100875 China

The Pearl River basin (PRB) is an important producing area and the gene pool of wild resources of Four Major Chinese carps (FMCC). However human activities and climate changes causes the area shrink of the river network in PRB, the pollution aggregation, the serious habitat destroy of aquatic organisms, and the threat of biological resources and their living environment. Based on the accurate location and distribution data of FMCC from the literature and the field survey report of 2015–2016, this study used the MaxEnt model to predict the hot spot distribution area of FMCC in PRB. The simulation results show that the distribution of FMCC in the PRB gradually increases from the upper reaches to the middle and lower reaches. According to the MaxEnt model, the hot spots of FMCC in the PRB are mainly distributed in the south reaches and the lower reaches of the southeast. The model simulation also demonstrates that the hottest spots for the distribution of FMCC species in the PRB are the Yujiang basin, the Qianjiang basin and the lower reaches of the Xijiang basin. This study can provide the scientific guidance for the protection and the restoration of FMCC species in the PRB. © 2022 The Authors

Economic activities release pollutants and carbon (mainly CO2) directly by consuming energy resources and indirectly by using energy-intensive goods. This research put forwards a grey model (GM) (1, 1) based input–output model (GIOM) for simulating pollutants and CO2 emissions in Fujian Province under varied socio-economic development scenarios. Major findings are: (i) in the planning period, Agriculture, forestry, animal husbandry and fishery (AGR) is the main sector for wastewater emissions in the planning period, and manufacturing and materials and energy conversion (MEC) sectors will be the main sectors for emissions of waste gases and CO2 in the planning period;(ii) through the simulation, the total energy consumption in Fujian Province increases by 13.53–51.08%, Metal and nonmetal products (MAN), MEC and Wholesale and retail transportation and warehousing (WRT) are the main energy consumers;(iii) the COD, NH3–N, SO2, and NOx emissions decrease 24.55–70.11%, 24.53–70.83%, 27.11–70.55% and 22.47–72.00% over time, and the CO2 emissions range from an increase of 36.35% to a decrease of 5.98% over time. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Development of seasonal ozone maximum reactivity scales for Beijing, China

Science of the Total Environment 2024年 957卷 177563页

作者： Zhou, Houhua Liu, Yanhui Tan, Zhaofeng Chen, Shiyi Zeng, Liming Li, Xin Lu, Keding State Key Joint Laboratory of Environment Simulation and Pollution Control College of Environmental Sciences and Engineering Peking University Beijing100871 China Environmental Analysis and Testing Laboratory Chinese Research Academy of Environmental Sciences Beijing100012 China

We designed scenarios based on urban emissions to develop a Maximum Incremental Reactivity (MIR) scale for 41 conventional volatile organic compounds (VOCs) in Beijing and quantitatively analyzed the various factors affecting MIR in urban areas. We explored the effects of updating the representative urban atmosphere used for ozone reactivity calculations by incorporating updated meteorological data, emission rates, initial condition concentrations, and VOC profile compositions. A box model equipped with the Master Chemical Mechanism (MCM) was used to localize the MIR scale for Beijing based on urban emission model inputs, and this was compared with scenarios in the United states. The MIR differences for most VOC species were minimal;however, Beijing exhibited higher MIR values for aromatic hydrocarbons in the summer, attributed to the higher emission intensity of aromatics in the city. Due to differences in meteorological conditions and emission scenarios, the MIR showed significant seasonal characteristics across different months. It is necessary to calculate independent MIR scales for different urban agglomerations under specific ozone pollution seasons and emission conditions. This study provides recommendations for the application of the MIR scale and can serve as a reference for VOC control strategies in China and other countries facing ozone pollution. © 2024
