中国区域滨海湿地固碳能力研究现状与提升

对我国滨海湿地的固碳能力进行了评估,同时,对其固碳能力的遥感监测和评估方法进行了总结和分析,最后提出了滨海湿地固碳能力的提升技术。全球看来,我国滨海湿地的固碳能力总体上不高。国内看来,在北方泥炭地和植被覆盖率高,生长茂盛的区域,尤其是有红树林生长的区域固碳能力相对较高。滨海湿地主要分布在潮间带,人为监测困难,卫星遥感的出现为滨海湿地的监测带来很大方便,遥感监测已成为评估湿地固碳能力的一种高时效方法。滨海湿地固碳蕴藏着巨大潜力,提升滨海湿地的固碳能力可以大大降低全球CO2含量,对于改善全球温室效应有不可替代的作用。

中国旅游科技创新的时空结构、重心轨迹及其影响因素研究

旅游产业是充满众多科技创新与成果转化的社会经济部门。以我国旅游产业相关发明专利、旅游收入、风景名胜区、高校学生数等为分析依据,基于地理集中指数、动态变动指数、空间重心模型和灰色关联分析等方法,对各省区2006—2017年旅游科技创新的时空结构、重心轨迹及其影响因素等进行实证研究。结果表明：时间上,我国旅游科技创新整体上呈波动上升的发展态势,2013年后地理集中度指数开始持续下降;空间上,旅游科技创新在我国呈东高西低、南高北低的分布格局。此外,旅游科技创新的空间重心位于我国华东地区,并呈先由北向南、再由东向西的移动轨迹。最后,科技创新产出、旅游经济水平、科技经费投入、经济宏观环境、科技创新服务、旅游资源禀赋等要素指标均对我国旅游科技创新产生一定影响,但影响程度具有差异。

Profitability of fossil-fuel production under different instruments in international climate policies

This article discusses how different climate policy instruments such as CO₂ taxes and renewable energy subsidies affect the profitability of fossil-fuel production, given that a fixed global climate target shall be achieved in the long term. Within an intertemporal framework, the model analyses show that CO₂ taxes reduce the short-term profitability to a greater extent than technology subsidies, since the competition from CO₂-free energy sources does not become particularly noticeable until decades later. Due to, for example, the discounting of future revenues, most fossil-fuel producers prefer subsidies to their competitors rather than CO₂ taxes. However, this conclusion does not apply to all producers. Oil producers outside OPEC lose the most on the subsidizing of CO₂-free energy, while CO₂ taxes only slightly reduce their profits. This is connected to OPEC's role in the oil market, as the cartel chooses to reduce its extraction significantly in the tax scenario. The results seem to be consistent with the observed behaviour of important players in the climate negotiations.
