    中国海总面积约470万平方公里,纵跨热带、亚热带、温带、北温带等多个气候带.其中,南海北依\"世界第三极\"青藏高原、南邻\"全球气候引擎\"西太平洋暖池,东海拥有全球最宽的陆架之一,跨陆架物质运输显著,黄海是冷暖流交汇区域,渤海则是受人类活动高度影响的内湾浅海.中国海内有长江、黄河、珠江等大河输入,外邻全球两大西边界流之一的黑潮.这些鲜明的特色赋予了中国海碳储库和通量研究的典型代表意义.文章从不同海区(渤海、黄海、东海、南海)、不同界面(陆-海、海-气、水柱-沉积物、边缘海-大洋等),以及不同生态系统(红树林、盐沼湿地、海草床、海藻养殖、珊瑚礁、水柱生态系统等)多层面对海洋碳库与通量进行了较系统地综合分析,初步估算了各个碳库的储量与不同碳库间的通量.就海气通量而言,渤海向大气中释放CO2约0.22Tg Ca-1,黄海吸收CO2约1.15Tg Ca-1,东海吸收CO2约6.92~23.30Tg Ca-1,南海释放CO2约13.86~33.60Tg Ca-1.如果仅考虑海-气界面的CO2交换,中国海总体上是大气CO2的\"源\",净释放量约6.01~9.33Tg Ca-1.这主要是由于河流输入以及邻近大洋输入所致.河流输入渤黄海、东海、南海的溶解无机碳(DIC)分别为5.04、14.60和40.14Tg Ca-1,而邻近大洋输入DIC更是高达144.81Tg Ca-1,远超中国海向大气释放的碳量.渤海、黄海、东海、南海的沉积有机碳通量分别为2.00、3.60、7.40、7.49Tg Ca-1.东海和南海向邻近大洋输送有机碳通量分别为15.25~36.70和43.39Tg Ca-1.就生态系统而言,中国沿海红树林、盐沼湿地、海草床有机碳埋藏通量为0.36Tg Ca-1,海草床溶解有机碳(DOC)输出通量为0.59Tg Ca-1;中国近海海藻养殖移出碳通量0.68Tg Ca-1,沉积和DOC释放通量分别为0.14和0.82Tg Ca-1.总计,中国海有机碳年输出通量为81.72~103.17Tg Ca-1.中国海的有机碳输出以DOC形式为主,东海向邻近大洋输出的DOC通量约15.00~35.00Tg Ca-1,南海输出约31.39Tg Ca-1.综上,尽管从海-气通量看中国海是大气CO2的\"源\",但考虑了河流、大洋输入、沉积输出以及微型生物碳泵(DOC转化输出)作用后,中国海是重要的储碳区.需要指出的是,文章数据是基于中国海各海区碳循环研究报道,鉴于不同研究方法上的差异,所得数据难免有一定的误差范围,亟待将来统一方法标准下的更多深入研究和分析.国家重点研发计划项目(编号:2016YFA0601400);;国家自然科学基金项目(批准号:91751207、91428308、41722603、41606153、41422603);;中央高校基础研究项目(编号:20720170107);;中海油项目(编号:CNOOC-KJ125FZDXM00TJ001-2014、CNOOCKJ125FZDXM00ZJ001-2014)资

    本文构建了一个包含自然灾害的两部门内生增长模型。研究发现,自然灾害对长期增长的影响幅度取决于其造成的人力资本存量损失。同时,灾害发生会促使经济主体更多地投资于人力资本。本文应用跨国数据分析了自然灾害风险、经济增长和人力资本投资间的长期关系,发现自然灾害对宏观经济活动有重要影响,并主要通过影响人力资本投资行为发生作用。In this paper we constructed a two departments endogenous growth model with natural disas- ters.Our study found that the way natural disasters impact on long-term growth rate depends on the los- ses of human capital stock.Disasters will lead families to invest in human capital.In the empirical study, we analyse the long-term relationship between risks of natural disasters,economic growth and investment in human capital.国家社科基金课题(06CJY002、07BJYl67);; 国家自然科学基金项目(70473106、70673116);; 教育部人文社会科学重点研究基地重大项目(05JJD790075);; 福建省高等学校新世纪优秀人才支持计划资助成果之

    To reveal the biomass changes of Suaeda glauca and Suaeda salsa as reciprocal companion under different additive amount of extraneous nitrogen, a field simulation experiment was conducted in the Yellow River Delta ecology research station of coastal wetland from May 2 to June 27, 2017. The two species were transplanted in to PVC pipe, with overall 108 PVC pipes laid. There were 3 planting densities (4 plants of dominant with 1 plant of companion, 2 plants of dominant with 1 plant of companion, and only 1 plant of dominant) were set in the experiment. Considering the situation of nitrogen deposition in the Yellow River Delta, 3 kinds of additive amount of extraneous nitrogen (0 g/m~2 nitrogen, 15 g/m~2 nitrogen, 30 g/m~2 nitrogen) were set, urea was as the nitrogen resource of extraneous nitrogen. The results showed that the average biomass accumulation of Suaeda salsa and Suaeda glauca both enhanced significantly along with increasing extraneous nitrogen input when planted 4 plants of dominant and 2 plants of dominant in each PVC pipe. When the additive amount of extraneous nitrogen were 15 g/m~2 nitrogen and 30 g/m~2 nitrogen, the biomass of Suaeda glauca was (58.0502.560) g per plant and (58.7403.170) g per plant, which were both significantly higher than that [(20.8500.640) g per plant] without extraneous nitrogen addition. The biomass of Suaeda salsa was (82.6401.330) g per plant and (111.9606.400) g per plant separately when the additive amount of extraneous nitrogen was 15 g/m~2 nitrogen and 30 g/m~2 nitrogen, which were also both significantly higher than that [(37.5001.750) g per plant] without extraneous nitrogen addition. Increasing additive amount of extraneous nitrogen promoted the biomass accumulation of Suaeda glauca and Suaeda salsa with an higher increase degree of the biomass of Suaeda salsa, indicating that increasing extraneous nitrogen promoted the growth of Suaeda salsa more strongly.</p
