【摘要】：自然变化及人类活动压力对海洋环境的影响方式和程度是基于生态系统海洋管理研究的重要内容,利用属性数据、基于DPSIR等概念模型进行分析评价难以反映问题的本质。为此,在海洋生态系统压力对状态影响特征分析的基础上,引入整体网方法,利用关系数据进行压力对状态影响的定性和定量分析,用度数中心性、中间中心性、接近中心性表征压力和状态因素在压力-状态网络中的地位和重要性,用影响力指数表征压力因素的重要性和状态因素受影响的程度。利用美国南佛罗里达海域MARES研究项目(the MARine and Estuarine goal Setting project)提供的数据进行实证分析,结果显示该海域12类主要压力因素中,径流注入对区域海洋生态系统状态影响最大,休闲垂钓的影响最小。11个主要状态因素中,保护物种、鱼类和贝类受到的压力影响力最大,是两种最易受到侵害的生态系统状态,上述结论可以为该海域的生态修复工作提供一定的指示。
[Abstract]:The influence of natural changes and human activity pressure on marine environment is an important part of ecosystem marine management research. It is difficult to reflect the nature of the problem by using attribute data and based on conceptual models such as DPSIR. Therefore, on the basis of the analysis of the characteristics of the influence of pressure on the state of marine ecosystem, the integral network method is introduced, and the qualitative and quantitative analysis of the influence of pressure on the state is carried out by using the relational data, and the degree centrality and the middle centrality are used. The importance and importance of pressure and state factors in pressure-state networks are characterized by approaching centrality, and the importance of stress factors and the degree of influence of state factors are represented by influence indices. Using the data provided by the MARine and Estuarine goal Setting project in the South Florida Sea area, the results show that the runoff injection has the greatest impact on the state of the regional marine ecosystem among the 12 major pressure factors in the sea area. Among the 11 main state factors, conservation species, fish and shellfish were the two most vulnerable ecosystem conditions. The above conclusions can provide some indication for the ecological restoration of the sea area.
