摘要
运用系统保护规划方法,进行了黄淮海地区湿地生态系统保护多预案分析研究。研究中以集水区为保护规划单元,综合考虑河流湿地生态系统、非河流湿地生态系统、保护物种、地下水等生物信息和路网、居民分布、水坝等社会经济信息,以及已有湿地保护区信息,以二维(2D)连接性(横向连接性、纵向连接性)和三维(3D)连接性(横向连接性、纵向连接性、垂向连接性)为原则,模拟研究了不同保护目标和不同保护格局聚集性的湿地保护预案。结果表明:基于2D连接性的研究,对河流湿地、非河流湿地和物种设定30%的保护目标,选取边界长度调节(BLM)值为0.36的保护格局聚集性,以此得到的保护方案相对合理;而基于3D连接性时,对河流湿地、非河流湿地和保护物种设定30%的保护目标,地下水设定55%的保护目标,选取0.06边界长度调节值的保护格局聚集性,得到的保护方案相对合理;基于3D连接性保护方案的效率要比基于2D连接性的高。对于严重缺水的黄淮海地区来说,3D连接性的考虑不仅必要,而且可行,具有重要的现实意义。
Located in the eastern coastal areas of China,featured with vast area of wetlands and rich biodiversity,HuangHuaiHai Region（HHHR） is an important place for migratory birds to survive during migration and wintering not only for China,but also for Northeast Asia Inland and Western Pacific Rim,which is a vital component of East Asian-Australasian Flyway.By applying basin units rather than administrative districts to account for the connected nature of wetlands,the study area of HHHR was defined,mainly made up of alluvial plain deposited by Yellow River,Huaihe River,Haihe River and their tributaries,covering an area of approximately 48000000 km2.As the political,economic and cultural center of China,with about 4 times population density of the national average,wetlands within HHHR not only played very important role in providing huge suitable habitats for various wildlives and great ecosystem services for local people,but had long been suffering from large-scale destruction and increasing degradation during the half past century.How to keep economy sustainable development while guarantee eco-conservation as well,multi-scenarios analysis based on Systematic Conservation Planning（SCP） should be the effectual tool in decision-making.Therefore,within the framework of SCP,taking catchments as planning units,considering comprehensively biological information（such as 23 riverine wetlands ecosystem types,8 non-riverine wetlands ecosystem types,distribution of 16 target species prioritized on IUCN Red List,5 exploitable aquifers） and socio-economic factors（such as road nets,settlement places,dams）,also with existed reserves concerned,based on 2D connectivity（lateral connectivity,longitudinal connectivity） and 3D connectivity（lateral connectivity,longitudinal connectivity,vertical connectivity） respectively,multi-scenarios for wetlands ecosystem conservation in HHHR were simulated firstly,then followed by scenarios comparison under different targets and compactness to develop the reasonable conservation
