China’s national carbon emissions trading scheme: lessons from the pilot emission trading schemes,academic literature,and known policy details     

Thomas Stoerk  Daniel J. Dudek  Jia Yang 《Climate Policy》2019,19(4):472-486

Upon completion, China’s national emissions trading scheme (C-ETS) will be the largest carbon market in the world. Recent research has evaluated China’s seven pilot ETSs launched from 2013 on, and academic literature on design aspects of the C-ETS abounds. Yet little is known about the specific details of the upcoming C-ETS. This article combines currently understood details of China’s national carbon market with lessons learned in the pilot schemes as well as from the academic literature. Our review follows the taxonomy of Emissions Trading in Practice: A Handbook on Design and Implementation (Partnership for Market Readiness & International Carbon Action Partnership. (2016). Retrieved from www.worldbank.org): The 10 categories are: scope, cap, distribution of allowances, use of offsets, temporal flexibility, price predictability, compliance and oversight, stakeholder engagement and capacity building, linking, implementation and improvements.

Key policy insights

• Accurate emissions data is paramount for both design and implementation, and its availability dictates the scope of the C-ETS.

• The stakeholder consultative process is critical for effective design, and China is able to build on its extensive experience through the pilot ETSs.

• Current policies and positions on intensity targets and Clean Development Mechanism (CDM) credits constrain the market design of the C-ETS.

• Most critical is the nature of the cap. The currently discussed rate-based cap with ex post adjustment is risky. Instead, an absolute, mass-based emissions cap coupled with the conditional use of permits would allow China to maintain flexibility in the carbon market while ensuring a limit on CO₂ emissions.

百色气候变化特征及城市适应策略建议     

何洁琳  陆甲  李艳兰  谢敏  黄卓  周美丽  黄雪松  秦川 《气象研究与应用》2019,(1):34-37

利用气候观测数据分析表明,近60a来,百色出现了与全球气候变化背景一致的增暖变化,主要变化特征有:气温明显升高,年降水日数减少,冬季降水量增多,年日照时数减少;高温和干旱频率高,20世纪90年代以来暴雨日数偏多。与广西平均气候变化状况相比,百色的气候变化程度风险低于广西平均水平。预估到本世纪中期,百色气温仍将缓慢升高,干旱和强降水的强度可能加剧。建议科学规划,统筹协调,科学评估城市气候承载力,开展城市适应气候变化风险管理,提升生态气候环境监测及自然灾害预警应急能力,建设生态气候宜居城市。  相似文献

Regional evapotranspiration rate of oasis and surrounding desert     

Jihong Jia  Wenzhi Zhao  Shoubo Li 《水文研究》2013,27(24):3409-3414

The surface energy balance algorithm for land method was used in this study to calculate the evapotranspiration (ET) rate for the middle reaches of the Heihe River Basin, Gansu Province, China, to analyse ET distribution within the oasis and the surrounding desert and, especially, on the edge zone of the oasis. Five profile graphs were created vertical to the river. Because of the inverse humidity phenomenon, the least amount of evapotranspiration occurred on the desert close to the oasis. The average evapotranspiration rate was roughly proportioned from the edge of the oasis to inside and outside its boundary. Two meteorological ground stations located close to the oasis edge showed a notable difference in net radiation flux that led to the difference found in ET. The primary reason for the significant differences observed in net radiation may be largely the result of differences in flux reflectivity and surface temperature. Meteorological data show that water supply also played an important role. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

冰冻圈显著的变化已经对冰冻圈水文过程产生了一系列影响。本文重点梳理和分析了近20年，尤其是近10年以冰川融水、融雪径流、冻土水文等为主体的中国冰冻圈水文过程变化研究方面取得的新进展：①在冰川融水变化研究方面，对不同尺度的冰川融水开展了全面研究，发现冰川融水呈现全面增加之势；对冰川融水"拐点"是否出现进行了科学辨识，有了基本认识；对冰川融水过程进行了模型模拟，取得显著进展。②在融雪径流变化研究方面，通过对不同流域融雪径流估算，可基本掌握各河流的融雪贡献率；中国融雪径流变化差异较大，增减不一；融雪期变化具有普遍性，突出特点是峰值提前。③在冻土水文研究方面，通过对地表水-活动层壤中流-多年冻土层上水之间关系的研究，揭示了冻土区径流形成的重力和热力耦合机制；多年冻土变化对地表径流的影响已经显现，主要表现在冬季（枯水季）径流增加；已经发现多年冻土退化对径流有直接补给作用，在一些流域补给量可能达到一定量级。  相似文献

双沟蛇绿岩中,变质橄榄岩的REE分布型式为LREE富集型,可能是富大离子亲石元素(LILE)组分交代造成的。地幔岩部分熔融生成的初始熔体LREE亏损,而辉绿岩和玄武岩则存在LREE亏损和富集两种型式,前者相当于N-MORB,后者相当于E-MORB。推测前者来源于亏损的软流圈地幔,而后者的地幔源区经历过一次富集LREE和LILE的事件。双沟蛇绿岩的REE特征暗示它可能形成于弧后盆地。  相似文献

吉林中部石炭系岩石建造及其构造环境     

贾大成  卢焱  崔圣哲 《吉林大学学报(地球科学版)》1994,(1)

吉林中部石炭系出露较全，具有独特的区域大地构造环境，在吉林晚古生代褶皱带演化中具有特殊性。本文将吉中石炭系划分为６个岩石建造，每一建造各具特征，并以岩石建造为手段，进行区域大地构造分析，认为该区石灰纪是在弧后一大陆边缘基础上形成的裂谷一拗陷带的构造环境，具有由先期裂谷发展阶段转变为末期拗陷带的演化过程，从而表明该区石炭纪为一拉张的构造历史时期。  相似文献
