基于SEM的钦州港生态承载力内涵及影响因素研究

Study on the Connotation and Influencing Factors of Ecological Carrying Capacity of Qinzhou PortBased on SEM

为了改善钦州港生态环境,促进区域协调发展,综合研究区域生态承载力概念和钦州港现实对钦州港生态承载力内涵进行界定,据此提出影响因素并借助结构方程模型定量验证,结果表明社会经济、港口资源和环境污染对钦州港生态承载力的影响显著,其中经济发展水平、社会进步与发展、自然资源条件、设施资源条件、水污染、大气污染和固体废物污染对钦州港生态承载力影响相对较大.根据研究结论,有利于在港口领域拓展生态承载力研究范畴,确定影响钦州港生态承载力的关键因素及未来深入研究方向,强化生态文明建设,焕发生态活力,具有重要的理论意义与现实价值.

In order to improve the port ecological environment,promote regional coordinated development,the concept of regional ecological carrying capacity and the reality of Qinzhou Port isintegrated to define the connotation of Qinzhou Port’s ecological carrying capacity,then the influencing factors are proposed and quantify verifiedby structural equation modeling.The results show that the socio-economic,port resources and environmental pollution have significant impacts on the ecological carrying capacity of Qinzhou Port,among others,economydevelopment level,social progress,natural resource conditions,facilities resource conditions,water pollution,air pollution and solid waste pollutionis relatively large.According to the research conclusions,it is beneficial to expand the research scope of ecological carrying capacity in the port field,determine the key factors affecting the ecological carrying capacity of Qinzhou Port and the future research direction,strengthen the construction of ecological civilization,revitalize the vitality,which has important theoretical and practical value.
