基于生态系统功能的大连市围填海资源潜力评估

将大连市围填海资源区划分为原生湿地(基岩海岸、砂质海岸、淤泥质海岸)和人工湿地(养殖池塘、水库、盐田)的基础上,评估了大连市围填海资源区生态系统服务价值,并结合通过遥感影像所提取的2000年、2010年大连市不同类型岸线长度和面积数据,构建基于生态系统功能的围填海资源潜力评估模型并对大连市围填海资源潜力进行评估,结果表明,大连市围填海资源区潜力值,人工湿地原生湿地,原生湿地围填海资源潜力为:砂质海岸粉砂淤泥质海岸岩石性海岸;人工湿地围填海资源潜力为:养殖池塘近岸水库盐田。

Assessment of the reclamation resource potential based on ecosystem function in Dalian City

In this study, the reclamation resource zones(RRZ) in Dalian were divided into two categories, original wetland and artificial wetland, of which, original wetland mainly was composed of bedrock coast, sandy coast and clay coast, while artificial one including farm pond, brine pan and reservoir. The ecosystem service values of the RRZ of Dalian coast were evaluated, the coast area and length data of different types of Dalian coast in 2000 and 2010 were extracted from the remote sensing images, the reclamation resource potential for Dalian coast were evaluated with the assessment model based on ecosystem function. Results showed that Reclamation resource potential value of Dalian coast is that: artificial wetland original wetland, the reclamation resource potential value of original wetland is that: sandy coast clay cost bedrock coast; the reclamation resource potential value of artificial wetland is that: farm pond reservoir brine pan.
