摘要
生态服务功能的研究在生态领域应用越来越广泛,通过生态服务功能的研究可以定量评估多种自然资源的分布状况.从生态系统服务功能角度入手,利用In VEST模型分别对海坛岛水源涵养功能、土壤保持功能、生物多样性功能进行评估,定量研究各种生态系统服务功能.通过叠加分析评估该地区综合生态系统服务功能,采用自然断点法划分等级得出重要生态系统服务功能区,并以此为生态源.利用最小累积阻力模型(MCR)构建海坛岛生态安全格局,并将生态安全格局分为生态源、低、中、高不同水平,其面积分别为:70. 49 km2、9 km2、21. 22 km2、60. 38 km2,生态安全格局面积之和为161. 10 km2,约占研究区总面积的49. 57%,能够提供较好的生态效益.生态安全格局对合理利用和管控土地空间,分配自然资源、调节经济发展与环境保护的相互平衡具有重要意义.
The research of ecological service function is becoming more and more widely used in the ecological field. Through the study of ecological service function,the distribution of natural resources can be evaluated quantitatively. From the perspective of ecosystem service function,this paper evaluates the water conservation function,soil conservation function and biodiversity function of Haitan island by using InVEST model,and quantitative studies various ecosystem service functions. Through the overlay analysis,the comprehensive ecosystem service function in this area is evaluated,and the natural breakpoint method is used to classify the important ecosystem service function area,which is the ecological source. The ecological security pattern of Haitan island is constructed by using the minimum cumulative resistance model(MCR),and the ecological security pattern is divided into ecological source,low,middle and high level. The area is 70. 49 km^2,9 km^2,21. 22 km^2 and 60. 38 km^2,and the area of ecological security pattern is 161. 10 km^2,which accounts for about 49. 57% of the total area of the study area. Enough to provide good ecological benefits. The ecological security pattern is of great significance to the rational utilization and control of land space,the rational distribution of natural resources,and the adjustment of the balance of economic development and environmental protection.
