文摘Carbon neutrality(or climate neutrality)has been a global consensus,and international experience exchange is essential.Given the differences in the degree of social development,resource endowment and technological level,each country should build a carbon-neutral plan based on its national conditions.Compared with other major developed countries(e.g.,Germany,the United States and Japan),China's carbon neutrality has much bigger challenges,including a heavy and time-pressured carbon reduction task and the current energy structure that is over-dependent on fossil fuels.Here we provide a comprehensive review of the status and prospects of the key technologies for low-carbon,near-zero carbon,and negative carbon emissions.Technological innovations associated with coal,oil-gas and hydrogen industries and their future potential in reducing carbon emissions are particularly explained and assessed.Based on integrated analysis of international experience from the world's major developed countries,in-depth knowledge of the current and future technologies,and China's energy and ecological resources potential,five lessons for the implementation of China's carbon neutrality are proposed:(1)transformation of energy production pattern from a coal-dominated pattern to a diversified renewable energy pattern;(2)renewable power-to-X and large-scale underground energy storage;(3)integration of green hydrogen production,storage,transport and utilization;(4)construction of clean energy systems based on smart sector coupling(ENSYSCO);(5)improvement of ecosystem carbon sinks both in nationwide forest land and potential desert in Northwest China.This paper provides an international perspective for a better understanding of the challenges and opportunities of carbon neutrality in China,and can serve as a theoretical foundation for medium-long term carbon neutral policy formulation.
文摘目的探讨沃里克-爱丁堡积极心理健康量表(Warwick-Edinburgh mental well-being scale,WEMWBS)在高职生群体中应用的信效度和跨性别测量等值性。方法采用WEMWBS、心理弹性量表简版(10-item Connor-Davidson resilience scale,CD-RISC-10)和12项一般健康问卷(12-item general health questionnaire,GHQ-12)对1312名高职学生进行调查。结果高分组与低分组高职生WEMWBS各项目得分的差异均有统计学意义显(P<0.001),WEMWBS各项目得分与总分均呈显著正相关(r=0.66~0.84,P<0.001)。探索性因子分析提取出1个公因子,累积方差解释率为61.02%;验证性因子分析结果显示:χ2=455.1,df=77,CFI=0.92,TLI=0.9,RMSEA=0.09,SRMR=0.04,模型拟合达到基本标准。WEMWBS总分与GHQ-12总分呈负相关(r=-0.53,P<0.001),与CD-RISC-10总分呈正相关(r=0.84,P<0.001)。WEMWBS的Cronbach’sα系数为0.95,3周后的重测信度为0.68。在测量等值性检验中,WEMWBS只符合形态等值和弱等值。结论WEMWBS应用于高职生群体具有良好的信度和效度,符合形态等值和弱等值。
