In order to assess the environmental risks caused by carbon emissions from the construction industry in Hebei Province of China,an environmental risk assessment model based on forest carbon sink threshold was constructed to evaluate the carbon emission risks of the construction industry in Hebei Province,China from 2005 to *** results are shown as follows:(1)The overall carbon emissions of the construction industry in Hebei Province of China showed an inverted"V"-shaped evolution trend during the past 16 *** and Shijiazhuang maintained high carbon emissions,while Langfang,Hengshui and Baoding saw rapid increases in carbon emissions.(2)The environmental safety threshold of carbon emission from the construction industry in Hebei Province,China,has been continuously improved,and the provincial environmental safety threshold is between 9475080-23144760 tons;The environmental safety threshold was the highest in Baoding and Langfang,and the lowest in Xingtai.(3)In the past 16 years,the carbon emission risk of the construction industry in Hebei Province of China has been in a state of extremely serious risk,and the risk index generally presents an inverted"V"type trend.(4)The carbon emission risk of Hebei city in China presents a spatial pattern of"high in the south and low in the north",which goes through two stages:risk increase period and risk reduction period.

森林碳汇是国际社会应对气候变化的重要举措，在国际法的框架之下，国内法如何对森林碳汇提供切实的法律保障，即国内法在应对森林碳汇方面如何做出具体的法律制度选择，是我国森林法制建设中的迫切问题。森林碳汇的法律制度选择应当体... 详细信息

森林碳汇是国际社会应对气候变化的重要举措，在国际法的框架之下，国内法如何对森林碳汇提供切实的法律保障，即国内法在应对森林碳汇方面如何做出具体的法律制度选择，是我国森林法制建设中的迫切问题。森林碳汇的法律制度选择应当体现森林生态学的规律，从森林培育的角度，法律制度的选择包括植树造林制度、封山育林制度、退耕还林制度；从森林保护的角度，法律制度的选择包括森林防火制度、森林病虫害防治制度、人为毁林的预防和惩处制度；从森林的可持续经营管理角度，法律制度的选择包括森林分类经营制度、森林碳汇交易制度、森林采伐制度、森林保险制度和森林认证制度。

从能源消费、水泥生产和森林碳汇3个方面对中国未来的碳排放进行了较为全面的估计。其中，能源消费碳排放是在能源—经济框架下利用经济动力学模型对最优经济增长路径下的能源需求进行预测得到的，同时考虑了能源结构的演化及不同能源品种在碳排放系数上存在的差异；水泥生产碳排放则是在对水泥产量预测的基础上进行的，认为水泥产量与城市化进程存在一定的联系，而城市化进程遵循“S曲线”发展规律；森林碳汇是通过引入CO2FIX模型，分别对原有森林与新增可造林的固碳能力进行估算，最终合成了中国未来的净碳排放曲线。结果发现，能源消费碳排放在2031年达到高峰，为2637MtC，对应的人均GDP低于OECD国家的实证经验；人均排放高峰出现在2030年，为1.73tC/人，远低于美国欧盟和日本2006年水平；水泥生产碳排放增长放缓，2050年控制在254MtC左右，占工业总排放的12％；森林碳汇至2050年可累计吸收6806.2MtC，年吸收量逐渐下降；净排放也于2033年达到峰值，为2748MtC。
