Due to the special geographical location and unique ecosystem of islands, appropriate development and protection of islands is important for promoting the sustainable development of islands. By using the Pingtan Islands as an example, this study constructed a system of suitability evaluation indexes for marine ecological space, marine agricultural production space and marine construction space under the principle of land–sea coordination. To evaluate the spatial suitability of the sea area around islands, a GIS spatial analysis method and a hierarchical analysis method (AHP) were used, which provided useful references for the integration of land and sea and for developing islands sustainably. The research results showed that the suitability area of ecological space in the Pingtan Islands accounted for around 64.3%, the construction space accounted for around 2.1% and the agricultural production space accounted for 33.5%.

【目的】推进海洋自然资源资产价值核算研究是海洋资源保值增值、维护海洋生态安全的重要课题。海洋因其特有的广阔性、流动性、连通性等特性,其资产价值的确认、计量、核算呈现出复杂性和特殊性,实践中存在核算范围不统一、价值内涵模糊、核算方法多样等问题,亟须推进构建统一的海洋自然资源资产价值核算方法。【方法】本文聚焦海洋自然资源资产内涵界定、价值构成分析、核算方法构建和账户体系编制4项关键问题开展海洋自然资源资产价值核算方法研究,建立了海洋自然资源资产价值核算系统性框架。进一步,以江苏省盐城市海洋自然资源资产为对象开展实证研究。【结果】①海洋自然资源资产包括海洋资源型资产和海洋生态型资产两类;②除部分交易市场比较活跃的资产价格可以通过直接市场法测算外,采用间接市场法或成本法测算资产价格,通过净现值法核算价值是目前适用于海洋自然资源资产价值核算的常用方法;③核算期间盐城市海洋自然资源资产价值呈上升趋势,期末资产价值总量比期初增长约1181亿元,增幅约44%,资源型资产价值是主要组成部分。【结论】将海洋自然资源资产分为资源型资产和生态型资产可以较为全面地反映海洋自然资源资产构成和价值实现情况,基于“实物量核算-价格测算-价值核算”的技术路线和分类型账户体系能够较为科学有效地核算海洋自然资源资产价值,反映资产数量、分布、价值,直观表达资产管理成效,为海洋自然资源资产价值核算提供了科学有效的技术路径和研究思路,可为自然资本核算、资产负债表编制等工作提供参考与借鉴。
