ABSTRACTS

New Binhai District activates Tianjin Port Infrastructure construction of new Binhai District includes ports, airports, railways and highways. The completion of comprehensive auxiliary facilities of contain delivery system in new Binhai District will drive and power sustainable development of Tianjin Port, which is in the node of comprehensive transpor- tation and logistics network and will provide effective guarantees for Tianjin Port to realize the 1 lth Five-Year plans. The development of modem manufacturing industry in new Binhai District and the increase of radiation ability on economical development in hinterland will promote the growth of logistics businesses. Tianjin Port will face the historical opportunity of rapid growth of throughput and the rapid expansion of port scale. Tianjin Dongjiang Bonded Port, as an important carder and one of new regions of orientation of new Binhai District, is the bonded port approved by the State Council under the background of economical globalization, The Dongjiang Bonded Port enjoys six bests in the country, i.e. the largest area, the best conditions, most preferential policies, highest efficiency, most convenient customs declaration processes and most relaxed environment, Upon the establishment of the bonded port, the State had encouraged new Binhai District to carry out financial reforms and innovation. Key reforms in terms of financial companies, financial businesses, financial market and opening of financial industry were trial implemented in new Binhai District in Tianjin. With the deepening of financial system reforms of new Binhai District, Tianjin Port will meet new opportunities for development of financial industry and expansion of financing. P16[第一段]     

植被碳汇计算方法在路域生态系统的应用前景

通过对模型模拟法、现场实测法、遥感估算法、通量观测法四种主要的陆地生态系统植被碳汇计算方法的归纳、总结,对比分析了四种方法的优缺点.在分析路域生态系统特点的基础上,探讨了四种植被碳汇计算方法在路域生态系统中应用的可行性.结果表明:四种植被碳汇计算方法在路域生态系统的应用具备一定的可行性,但是需要根据环境特点、公路特征和研究目的进行合理选择、调整和组合.然而,目前尚缺乏应用案例,实证研究亟待加强.因此,针对研究现状,对交通行业今后的植被碳汇研究工作提出了建议,以期为我国公路路域植被碳汇计算及相关研究提供有益的借鉴.     

公路景观生态系统恢复的生态补偿设计研究

通过对国内外公路景观的发展进行分析,展开公路景观生态系统恢复与重建的生态补偿设计的可行性方案与技术研究,建立了包括公路沿线乡土植物群落景观生态系统、公路护坡景观生态系统、生态敏感区景观生态系统等恢复与重建的补偿设计体系.提倡遵循自然规律,通过生态补偿设计恢复与重建因破坏而退化的生态系统,构建公路景观安全格局,实现公路景观生态系统的良性循环和环境的可持续发展.公路景观生态系统恢复重建的生态补偿设计较好地解决了公路建设中资源利用与环境保护的矛盾问题,为介于交叉学科的公路建设、景观设计、环境生态保护等研究领域提供借鉴.     

核心企业主导型产业创新生态系统竞争演化研究

为探讨核心企业主导下的产业创新生态系统竞争演化规律,运用生态学理论构建加入配套企业单元影响作用的产业创新生态系统竞争演化模型,并仿真不同竞争系数和创新贡献率下系统的稳定竞争模式.模型分析及仿真结果表明,竞争企业和配套企业相互作用推进产业创新生态系统竞争演化,核心企业规模与竞争企业竞争系数成反比,与配套企业创新贡献率成正比;针对竞争企业和配套企业,提出核心企业应提高自身核心竞争力和汲取配套企业提供的互补或补充性创新技术和服务中的有利创新因素的建议.最后通过对以苹果公司和华为科技有限公司为例的现代移动通信产业进行实证研究,给出相关管理对策与建议.     

Case Study of Marine Ecological Compensation Criteria Based on Environmental Risk

This paper forecasted and identified the environmental risks and ecological effect caused by chemical spill by simulating the xylene spill in Xiamen waters. The evaluation objects of ecological damage include four parts: marine ecosystem services, sea water quality, marine biological resources (plankton, benthos, nekton, etc.), and beach habitat. The ecological compensation criterion was confirmed as 1.73 million Yuan per year in the short term and 8.09 million Yuan in the long term. And an ecological compensation mode was suggested to be that if the chemical spill does not occur this year, the compensation will return to the enterprise next year; while if chemical spill occurs, the compensation will not be returned. The encouragement mechanism "returning compensation if no spill" might motivate enterprises to improve the environmental risk management and avoid the risks.     

长湖申线航道改造中生态护岸的应用探讨

以往人们在城市河道整治过程中只考虑到工程结构的安全性及耐久性,故多采用砌石、混凝土等材料修筑硬质护岸,隔断了水生生态系统和陆地生态系统之间的联系,导致河流失去原本完整的结构和作为城市生态廊道的功能,进而影响到整个城市生态系统的稳定。因此,做好城市河流的生态修复工作对于生态城市的建设具有十分重要的意义。     

生态水利工程的河道规划设计

生态水利工程的河道规划设计是为了保护和修复河流生态系统,实现水资源的合理利用和生态环境的可持续发展。本文从技术要点和设计方向两个方面进行论述,分析了生态水利工程河道规划设计的重要性和实施方法,并总结出设计的关键要点。     

基于模糊综合评价法的海岛潮间带生态系统现状评价

本文基于模糊综合评价法,构建了潮间带生态系统评价体系,并以南澳岛为研究对象,结合实测数据,分析结果显示南澳岛潮间带水质以及沉积物环境状况较好,沉积物环境状况基本为优,水质也基本处于优～良的水平,但是水生生物状况堪忧,特别是浮游动物和底栖动物的多样性评价结果基本处于良～一般,说明潮间带生态系统的平衡遭到一定的破坏,水生生物优势种的密度较高,揭示外来物种入侵的可能。

大连市渔港邻近海域环境系统健康评价

本文选用2011年三次对大连近岸渔港邻近海域所做水质、沉积物、生物等的监测数据,采用国家海洋局2005年颁布的《近岸海洋生态健康评价指南》中“河口及海湾生态系统生态环境健康评价方法”,对监测海域的海洋生态环境健康状况加以评价。结果显示,大连市渔港邻近海域总体呈亚健康状态,海洋生态环境较为脆弱。
