黑龙江省兴凯湖自然保护区生态系统固碳服务功能评价

湿地是自然界中重要的“碳汇”，其碳储量变化对全球气候变化和温室效应有重要的影响.选择地理位置独特的黑龙江兴凯湖自然保护区作为研究区，根据保护区内不同土壤类型采集表层（0～20 cm）土壤样品，利用遥感解译的保护区土地利用图、土壤储碳量和植物固碳量计算公式，核算兴凯湖自然保护区生态系统固碳服务总量，同时借鉴瑞典碳税法和中国造林成本法，估算兴凯湖保护区固碳服务功能价值为4.9亿元.结果显示，兴凯湖自然保护区湿地固碳服务功能高于全国平均水平，且高于同纬度同属东北平原的莫莫格湿地，为保护区今后的保护管理策略提供了有效的参考依据.

EVALUATION ON THE ECOSYSTEM SERVICE FUNCTION OF CARBON SEQUESTRATION IN XINGKAI LAKE NATURE RESERVE,HEILONGJIANG PROVINCE

Wetland serves as an important "carbon sink" in nature, and its carbon stock variation has significant influence on global climate change and greenhouse effect. Selecting the geographically unique Xingkai Lake Nature Reserve in Heilongjiang Province as the study area and collecting the surface soil samples (0-20 cm) in terms of soil types, the research uses remote sensing-interpreted land use map, calculation formula of soil carbon storage and plant carbon sequestration to count the total carbon sequestration amount of ecosystem service in the reserve. Besides, the carbon sequestration service value is estimated to be RMB 490 million by referring to Sweden's carbon tax approach and China's afforestation cost approach. The results show the carbon sequestration service function of wetland is above the national average and that of Momoge wetland on the same latitude in Northeast China Plain, which provides effective reference for protection and management of the study area in the future.
