摘要: 如何充分利用有限的资源更好地保护生物多样性一直都是保护地管理所追求的目标。整合保护对象、优化保护地的空间布局、有效识别国家公园优先保护区域是当前中国国家公园体制建设的主要任务。本研究以浙江丽水为例,采用生态模型评估了该区域关键生态系统服务(固碳释氧、水文调节、水资源、土壤保持)的空间分布格局,同时运用MaxEnt模型模拟了37种濒危物种适宜栖息地分布的空间格局。在此基础上,将关键生态系统服务和濒危物种作为保护对象,通过系统保护规划模型MARXAN,在0.4 km×0.4 km规划网格上计算丽水各规划单元的生态保护不可替代性指数,并结合当地管理需求,综合识别了国家公园优先保护区域。结果表明: 2005—2015年间,研究区生态系统固碳量为0.05 kg C·m-2·a-1,释氧量为0.13 kg O2·m-2·a-1,水文调节量为83.25亿m3·a-1,水资源量为803 mm·a-1,土壤保持量为95.53 t·hm-2·a-1;不同土地利用类型的不可替代性指数显著不同,森林为50~100,河流和水库为60~100,园地为30~50,耕地为15~35,住宅用地为0~25,优先保护区域占研究区面积的11.8%。本研究结合生物多样性和生态系统服务的系统保护规划思路,能够为保护地网络优化布局和国家公园优先保护区域的确定提供有用的框架和技术支撑,有助于提升我国建设以国家公园为主体的自然保护体系的整体有效性。

Abstract: It is the goal of protected area management to make full use of limited resources to better protect biodiversity. Currently, the main tasks of developing national park system in China are to combine conservation features, optimize the spatial network of protected areas, and identify the prio-rity conservation areas of national parks effectively. In this study, we assessed the spatial distribution of key ecosystem services (carbon sequestration, oxygen release, hydrological regulation, water resources, and soil retention) using ecological model, and simulated the distribution of suitable habitats for 37 endangered species by MaxEnt in Lishui City, Zhejiang Province. The irreplaceability index of each planning unit in Lishui was calculated on the 0.4 km×0.4 km grid using the systema-tic conservation planning model (MARXAN), setting key ecosystem services and endangered species as the conservation objects. Combined with the local management needs, the priority protection areas of national parks were identified comprehensively. The results showed that during 2005 to 2015, the annual carbon storage, oxygen release, hydrological regulation, water resource, and soil retention in the study area was 0.05 kg C·m-2·a-1, 0.13 kg O2·m-2·a-1, 83.25×108 m3·a-1, 803 mm·a-1, and 95.53 t·hm-2·a-1, respectively. The irreplaceability index of different land use types was significantly different. The irreplaceability index of forest, river and reservoir, garden, cultivated land, residential land was 50-100, 60-100, 30-50, 15-35, 0-25, respectively. The priority conservation areas accounted for 11.8% of the study area. This study put forward a systematic conservation planning idea combining biodiversity and ecosystem services, which could provide a useful framework and technical support for optimizing the network layout of protected areas and priority conservation areas of national parks, and help to enhance the overall effectiveness of the establishment of the protected areas system with national parks as its main type in China.
