摘要
划分均质区域是海洋资源资产清查实物量核算的重要内容,目前划分均质区域主要依据海洋功能区划,划分结果相对粗放,与现阶段海洋开发利用、自然条件、海洋规划等现状符合度不高,也难以满足资产经济价值评估需求。有鉴于此,提出一种基于自适应三角网的海洋均质区域划分方法。通过与海洋功能区划、海上风电规划、养殖用海规划等对比分析,结果相对海洋功能区划更加细化,且与自然条件、开发利用情况、用海规划等符合度更高,具有更好的合理性和可靠性,期望可为海洋资源资产管理提供新的思路和参考。
The partition of homogeneous area is an important part of marine resource assets inventory accounting.Marine functional regionalization was formerly used to divide homogeneous area as base map,but the results were not exactly precise,in which the current utilization status,ecological conditions,marine planning and others were not considered.A method based on adaptable triangular grid was proposed in our study to derive more precise marine homogeneous areas.A comparative analysis was made between calculation results and the marine functional regionalization,offshore wind power planning and sea aquaculture planning.Obviously,the new method was more practical and reasonable.It is expected that our study can provide new ideas and references for marine resource asset management.
