【摘要】：集约用海是一种相对科学、高效、生态的用海方式,但也不可避免的要占用和消耗海洋资源。因此开展集约用海对海洋资源影响的科学评估,将集约用海对海洋资源的影响降到最低就尤为重要。通过分析集约用海工程对海洋资源的影响,明确了集约用海工程对海洋资源影响影响评价的主要内容和思路,从海洋资源的复杂性及其开发利用角度,构建了基于海洋生物资源、海洋空间资源、港口航道资源、滨海旅游资源和其它资源的集约用海对海洋资源影响的综合评价指标体系。其中,从浮游植物、浮游动物、底栖生物和鱼类生物方面反映集约用海工程对海洋生物资源的影响;从滨海湿地、岸线、海域空间利用变化方面反映集约用海工程对海域空间资源的影响;从水动力变化、港口资源利用方面反映集约用海工程影响下港口航道资源的影响;从旅游资源密度反映集约用海工程对滨海旅游资源的影响;从矿产资源、能源资源利用方面反映集约用海工程对其它资源的影响。在此基础上,根据我国海洋资源调查与评估现状,研究并确立了集约用海对海洋资源影响的各评价指标权重、评价标准及评价等级,建立了基于赋值法、综合评价法的集约用海对海洋资源影响的综合评价模型,利用综合评估指数I来反映集约用海工程对海洋资源的影响程度。利用该评价方法评价了曹妃甸区域集约用海对海洋资源的影响,结果表明该区域集约用海对海洋资源造成的影响较大,应严格控制该区域集约用海工程。
[Abstract]:Intensive sea use is a relatively scientific, efficient and ecological way of using the sea, but it is inevitable to occupy and consume marine resources. Therefore, it is particularly important to carry out the scientific assessment of the impact of intensive sea use on marine resources and to minimize the impact of intensive sea use on marine resources. By analyzing the influence of intensive sea use engineering on marine resources, this paper clarifies the main contents and ideas of the impact assessment of intensive sea use engineering on marine resources, and constructs a comprehensive evaluation index system based on marine living resources, marine space resources, port and waterway resources, coastal tourism resources and other resources from the point of view of the complexity of marine resources and their development and utilization. Among them, the influence of intensive sea use engineering on marine living resources is reflected from the aspects of zooplankton, benthos and fish organisms, the influence of intensive sea use engineering on sea area space resources is reflected from the aspects of coastal wetlands, shoreline and sea area space utilization, and the influence of port waterway resources under the influence of intensive sea use engineering is reflected from the aspects of hydrodynamic change and port resource utilization. The influence of intensive sea use project on coastal tourism resources is reflected from the density of tourism resources, and the influence of intensive sea use project on other resources is reflected from the aspects of mineral resources and energy resources utilization. On this basis, according to the present situation of marine resources investigation and assessment in China, the weight, evaluation standard and evaluation grade of each evaluation index of the impact of intensive sea use on marine resources are studied and established, and the comprehensive evaluation model of intensive sea use on marine resources based on assignment method and comprehensive evaluation method is established, and the comprehensive evaluation index I is used to reflect the influence degree of intensive sea use engineering on marine resources. The influence of intensive sea use on marine resources in Caofeidian area is evaluated by using this evaluation method. The results show that the intensive sea use in this area has a great influence on marine resources, and the intensive sea use project in this area should be strictly controlled.
