【摘要】：随着港航运输业的快速发展,港口的规模在不断扩大,然而,目前港口在规划建设阶段缺少对生态环境的保护,使得港口建设与运营的过程中对周边生态环境造成破坏,尤其是在港口建设过程中,大量的生态用地被开发为建设用地,导致生态系统服务功能减弱,生态系统服务价值损失严重。目前,国内外的研究重点主要是对不同类型的自然生态系统和城市生态系统进行生态服务价值评估,而对港口这类特殊人工-自然-社会复合生态系统服务价值评估的研究很少,本研究在已有的研究成果基础上,把港口生态系统作为城市生态系统的子系统给予定义。本研究综合考虑人工、自然、社会三方面因素对生态系统服务价值当量进行了海岸带因子修正、生物量因子修正和社会经济因子修正,同时考虑了港口建设用地的生态服务负价值,建立了港口生态系统服务价值评估模型,并通过算例对港口生态系统中各项服务功能价值进行计算。算例结果表明,港口生态系统中生态用地大量减少,而建设用地大量增加,说明随着港口建设规模的扩大,大量生态用地转变为建设用地,生态服务价值损失严重。本论文根据港口生态系统服务价值评估模型,将港口建设对周边生态环境的影响进行了定量化研究,研究成果可为港口规划提供直观、有效的参考。
[Abstract]:With the rapid development of port and shipping industry, the scale of the port is expanding. However, at present, the port lacks the protection of the ecological environment in the stage of planning and construction, which causes the destruction of the surrounding ecological environment in the process of port construction and operation, especially in the process of port construction, a large number of ecological land has been developed as a construction land. The function of ecosystem services is weakened and the value of ecosystem services is lost seriously. At present, the focus of research at home and abroad is to evaluate the value of ecological services for different types of natural ecosystems and urban ecosystems, and the research on service value evaluation of the special artificial natural social complex system in ports is rarely studied. On the basis of the existing research results, the port ecosystem is defined as the subsystem of the urban ecosystem. This study comprehensively considers three factors of artificial, natural and social factors to modify the ecological system service value equivalent, the revision of the biomass factor and the social and economic factors, and the consideration of the port. The ecological service value of the construction land is negative, the evaluation model of the port ecosystem service value is set up, and the value of various service functions in the port ecosystem is calculated by an example. The results show that the ecological land in the port ecosystem is greatly reduced and the construction land is increasing, indicating that with the expansion of the port construction scale, A large amount of ecological land is transformed into construction land, and the value of ecological service is lost seriously. This paper makes a quantitative study on the impact of port construction on the surrounding ecological environment according to the evaluation model of the port ecosystem service value. The research results can provide direct and effective reference for port planning.
