【摘要】：岸线资源利用管理是沿海地区经济可持续发展的重要支撑,因此开展岸线集约利用评价具有重要的意义。本文首先建立了岸线资源评价指标体系,并从资源优化配置的角度,建立了以遥感数据为主要数据源的岸线集约利用评价指标体系。通过对遥感影像(SPOT)的解译并结合实地调查与经济统计数据获取相关评价指标信息,构建基于层次分析法的岸线资源评价模型和岸线集约利用评价模型,并应用其对天津中心渔港项目进行评价,结果表明:(1)天津中心渔港的岸线资源评价综合得分为3.004,其占用的岸线等级属于3级岸线;(2)天津中心渔港的岸线集约利用综合得分偏低,只有0.3271。各项指标中,岸线利用状况指标得分相对较高,约占综合得分的49.25%;而中心渔港的岸线投入产出水平指标得分最低,仅占17.27%。研究表明,围填海面积开发强度过低是导致天津中心渔港岸线集约利用强度偏低的主要原因。
[Abstract]:The utilization and management of shoreline resources is an important support for the sustainable economic development of coastal areas, so it is of great significance to carry out the evaluation of intensive utilization of shoreline resources. In this paper, the evaluation index system of shoreline resources is first established, and from the point of view of the optimal allocation of resources, The evaluation index system of shoreline intensive utilization based on remote sensing data is established. The evaluation index information is obtained by interpreting remote sensing image SPOT and combining with field survey and economic statistics data. The evaluation model of shoreline resources and the evaluation model of intensive utilization of shoreline were constructed based on AHP, and the evaluation of Tianjin central fishing port project was carried out. The results show that the comprehensive score of evaluation of shoreline resources of Tianjin Central Fishery Port is 3.004, and its occupation grade belongs to Grade 3 shoreline. The comprehensive score of intensive utilization of shoreline of Tianjin Central Fishery Port is on the low side, which is only 0.3271.Of all the indexes, The shoreline utilization index score is relatively high, accounting for 49.25 of the comprehensive score, while the shoreline input-output level index of the central fishing port has the lowest score, accounting for 17.27 percent. The low development intensity of reclamation area is the main reason for the low intensity of intensive utilization of the shoreline of Tianjin central fishing port.
