Carbon Intensity Market Trading Scene Setting and Policy Research in China
 [PDF]


Journal of Low Carbon Economy (JLCE) , 2016, DOI: 10.12677/JLCE.2016.51002
Abstract:
全球气候变化问题在《京都议定书》的协议之下,萌生了全球碳排放权的交易市场。我国的碳交易市场的建设刻不容缓,但是不能照搬发达国家的模式,应该寻找适合我国国情的碳减排途径。为实现我国碳强度减排的目标,本文设置了跨行业、跨区域和跨期三种碳强度交易情景。并且,为保证三种碳强度市场交易机制的顺利实施,对三种交易情景的碳交易进行了相应的配套政策引导和行政手段管理,从而更好地促进我国碳交易市场的健康发展。
Under the Kyoto protocol in face to the global climate change problem, the global carbon emis-sions trading market initiated. It is very urgent to the construction of the carbon trading market in China. But our market cannot copy the mode of developed countries, it should be to find a way suitable for the situation of our country’s carbon emissions. In order to achieve the goal of China’s carbon intensity reduction goal, this paper sets up three kinds of carbon trading scenes, including market trading of cross-industry, cross-regional and inter-temporal. In order to ensure the smooth implementation of market trading mechanism, three scenes of carbon trading have situated the corresponding supporting policies to guide market and administrative means to manage trading. It can promote the healthy development of the carbon trading market in China.

Abstract:
在自我参照记忆效应中加入生态自我参照任务,探索是否存在与个体自我参照及群体参照同样的记忆优先效应。实验结果表明:以生态自我为参照的加工任务的再认成绩与语义参照加工任务的再认成绩之间并不存在显著的差异,但在R与K指标上,生态自我参照的R值显著高于语义参照,反映出了生态自我参照能够促进记忆的加工。
Joining the ecological self reference processing tasks into the self reference memory effect is to explore whether the memory is priority as that in the individual self-reference and the group- reference. The results from the experiment showed that: ecological self referential processing task and semantic processing task did not differ in recognition rates. However, “Remember” judgment rates were significantly higher in ecological self referential processing task than those in semantic processing task, which reflected the promotion of ecological self reference on memory.

Abstract:
面对气候变化的严峻形势,我国在推进碳减排工作中制定了相关政策和实践。但是由于现行环境管理推进模式存在很多弊端,使得我国的碳减排工作困难重重。因此,我国必须探寻一种新型的碳减排制度,提高我国碳减排领域的效率,降低减排成本。国际社会上碳排放强度提出后,显示出其对经济增长和治理环境问题的重要作用。联合国气候大会上,我国政府提出了基于碳强度指标的自愿减排的目标。因此,本文采用规范分析方法,提出建立碳强度约束下的碳金融市场是我国应对气候变化的必然制度选择。最终得出结论,我国需要从特殊国情出发,将碳强度与碳市场进行有机结合,建立一个基于碳排放强度指标减排的碳金融市场。并需要在限定排放目标的基础上,明确买卖主体,完成碳强度指标与碳总量指标的转化,最终实现分行业、分地区的碳交易。
Face to the serious situation of climate change, China has made the related policies and practices in promoting carbon reduction work. But, the current environmental management advance mode has many disadvantages; it made the carbon reduction work hard. Therefore, China must explore a new type of carbon reduction system to improve the efficiency in the field of carbon emissions, and also reduce the costs. Now, the international community has raised carbon intensity reduction mode, and it has showed its important role in economic growth and governance facing to the en-vironmental problems. In the UN climate conference, the Chinese government has presented the carbon intensity of voluntary emission reduction targets. Therefore, the establishment of carbon financial market under the restriction of carbon intensity is the necessary choice in China using the standard analysis method. We need to start with special national conditions in China, combine the carbon intensity to carbon market, and finally create a carbon market based on carbon emission intensity target. And we need to clear trading bodies, complete the conversion of total carbon to carbon intensity index on the basis of defining emission targets, and ultimately complete industry and region carbon trade.

- , 2018, DOI: 10.13982/j.mfst.1673-9078.2018.2.032
Abstract: 为研究低温预贮(Low temperature conditioning,LTC)对青尖椒果实冷害的影响,本实验将青尖椒分为两组处理,分别为对照组(4 ℃贮藏25 d)和LTC组(10 ℃贮藏2 d再放入4 ℃贮藏23 d),测定贮藏期间青尖椒果实的冷害指数、相对导电率、丙二醛、叶绿素、POD、APX和CAT等生理指标,探究LTC处理对青尖椒果实冷害发生的影响。研究结果表明,相对于直接将青尖椒放入冷库贮藏,LTC处理可更好抑制青尖椒冷害的发展,有效减缓青尖椒冷害指数的增加,抑制相对导电率的升高和丙二醛(MDA)含量的积累,延缓Vc和叶绿素含量的下降,提高青尖椒果实细胞内过氧化氢酶(CAT),过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)的活性,提高青尖椒果实抗冷性,保存青尖椒的贮藏品质,延长青尖椒果实贮藏时间。
In order to investigate the effect of low temperature conditioning (LTC) on the chilling injury of green pepper, the green pepper was divided into two groups: control group (stored at 4℃ for 25 days) and LTC group (stored at 10℃ for 2 days, and then stored at 4℃ for 23 days). The chilling injury index, relative conductivity, malondialdehyde, chlorophyll, peroxidase (POD), ascorbate peroxidase (APX) and catalase (CAT) were measured during storage to investigate the effects of LTC treatment on the chilling injury of green pepper. The results showed that, compared with control group, LTC treatment could inhibit the development of chilling injury, which could effectively reduce the chilling injury index and inhibit the increase of relative conductivity and MDAcontent, delay the decrease of vitamin C (VC) and chlorophyll content , improve the activity of antioxidant enzymes (including CAT, POD and APX) in the cells of green pepper, improve the cold resistance of green pepper, preserve the quality of green pepper and extend the storage time of green pepper.

Abstract:
长期以来,鄱阳湖水温测验工作一直采取人工观测方式,这种方式易于保证测验质量,但工作量大,且效率低下。本文以鄱阳湖星子水文站为例,基于自记水温计与人工观测水温的同步观测资料,探讨两者之间的关系,并建立几种水温关系模型,分析比较各模型优缺点,分析误差产生的原因。结果表明:混合模型法精度最高,模拟值与真值误差在0.4℃以内,自记水温计观测数据经过换算后,可以用于湖区水温资料的整编。表明自记水温计可为水文巡测工作提供有效的支持,并在水文巡测中起到一定的作用。
Human observation of water temperature can ensure the quality of data, but the work is in effective. Based on synchronous temperature data from the recording temperature and human observations, this paper analyses their relationship and establishes relationship models. The strength and weakness of these models are discussed. Test results show that the hybrid model has the highest precision and the simulation values are consistent with the true values. The maximum absolute error is less than 0.4?C. Recording temperature data after conversion can be used in Poyang Lake water temperature data base. It is suggested that recording thermometer can provide effective support of hydrological survey work.
