The research and application on protection and development of eco-service function of urban emergency water sources

水资源的持续供给直接关系到城市社会稳定和经济持续发展，但是随着城市社会经济迅速发展和人口增长，对于水资源持续供给的保障却没有跟上城市发展的步伐，其中又突出表现在水源地污染和城市供水系统安全隐患等环节。因此，城市水源地保护和城市供水体系安全研究，对于保障城市供水安全乃至城市持续发展都具有积极的意义。 本文选取厦门本岛的应急水源湖边水库作为研究对象，其水质现状及整治问题具备城市水源地保护和开发问题的共性；论文以城市可持续发展、环境经济学、生态系统服务功能等理论为指导；以文献研究、资料收集、实地调查等方法相结合；采用市场价值法、影子价格法、影子工程法、旅行费用法、机会成本法以及水环境容量计算模型等...The sustained supply of water resources have a direct relationship with the city's social stability and sustainable economic development as a whole, but with rapid socio-economic development and population growth in cities, sustained supply of water resources do not kept pace with urban development, and it is highlighted by taches such as water pollution and security risks in urban water supply sy...学位：理学硕士院系专业：海洋与环境学院环境科学与工程系_环境科学学号：2005130226

海岛生态脆弱性驱动机制及对策措施初探——以平潭岛为例

海岛是海洋生态系统的重要组成部分,处于海陆相互作用的动力敏感地带,生态环境较为脆弱。本文以福建平潭岛为例,对海岛生态环境脆弱性的表现进行了阐述,分析了海岛生态脆弱性的驱动机制,并提出了平潭岛开发利用和生态环境良性发展的对策措施,以实现资源环境与社会经济的可持续发展。国家海洋局第三海洋研究所基本科研业务费专项资金资助项目;项目编号:海三科200904

Ambient nitrate switches the ammonium consumption pathway in the euphotic ocean

高树基教授研究团队的研究论文，以现场原位速率观测与环境因子调查，证明了环境硝酸盐浓度是调控海洋真光层不同氨氮消耗途径的关键因子。硝酸盐通过影响浮游植物对于氨氮吸收的能力，决定了真光层内氨氮的氧化路径强弱，刻画了海洋真光层氮循环的微结构。高树基团队利用同位素示踪培养技术，围绕南海和西北太平洋真光层内硝化作用和浮游植物氨氮吸收速率的垂直分布特点及其动力学特征进行研究。首次提出硝酸盐浓度通过影响不同浮游植物类群对于氨氮的吸收能力，从而调控真光层的氨氮消耗途径。研究团队的万显会博士为成果的第一作者，近海海洋环境科学国家重点实验室的戴民汉教授，史大林教授、张瑶教授、盛华夏博士后、祝依凡，以及澳大利亚联邦科学与工业研究组的Tom Trull教授和美国Bigelow海洋实验室的Mike Lomas教授为成果的共同完成人。【Abstract】Phytoplankton assimilation and microbial oxidation of ammonium are two critical conversion pathways in the marine nitrogen cycle. The underlying regulatory mechanisms of these two competing processes remain unclear. Here we show that ambient nitrate acts as a key variable to bifurcate ammonium flow through assimilation or oxidation, and the depth of the nitracline represents a robust spatial boundary between ammonium assimilators and oxidizers in the stratified ocean. Profiles of ammonium utilization show that phytoplankton assemblages in nitrate-depleted regimes have higher ammonium affinity than nitrifiers. In nitrate replete conditions, by contrast, phytoplankton reduce their ammonium reliance and thus enhance the success of nitrifiers. This finding helps to explain existing discrepancies in the understanding of light inhibition of surface nitrification in the global ocean, and provides further insights into the spatial linkages between oceanic nitrification and new production.This work is supported by the National Natural Science Foundation of China through grants 91328207, Science Fund for Creative Research Groups of the National Natural Science Foundation of China through grants 41721005 and National Basic Research Program of China (973 Program) through grants 2014CB953702, 2015CB954003.

发展生态工业园,促进我国节能减排目标的实现

随着我国工业的飞速发展,"高投入、高消耗"的传统生产模式已使环境资源难堪经济发展之负,如何扭转这一态势,是我国目前一件迫在眉睫的大事。实施节能减排、推行循环经济、发展生态工业,是改善这一局面的有效手段。本文对我国生态工业园发展情况进行回顾,并重点通过吸收生态工业园创建的成功经验,结合生态工业园建设的理论,提出改进的建议,力图促进我国生态工业的发展,实现国家节能减排的目标,使经济和环境协调发展

Nutrient Retention in the Jiulongjiang Reservoir Reach

通过估算2007年我国南方溪流九龙江流域库区河段的nH4-n和TP的输送通量,探讨水库对营养盐的滞留效应。该河段径流量和营养盐通量均表现出丰水期高枯水期低的季节性特征。系统对nH4-n存在较强的正滞留效应,滞留率为32%,对总磷的滞留率为-10%,可能是河流“湖库化“导致河流沉积物中磷大量释放。Here,we presented the estimated NH4-N and TP budget in the Jiulongjiang Reservoir Reach in 2007 to find out the effect of nutrition retention.The results reveal that the amount of runoff and the nutrient flux were both high in the wet season and low in the dry season.The NH4-N was highly retained at a rate of 32%.While the TP retention rate was-10%,it is possibly because a large amount of TP was released from the sediments when the river was turned into a reservoir.国家自然科学基金资助项目(No.41175130);教育部新世纪优秀人才支持计
