摘 要：
森林生态系统是陆地生态系统的重要组成部分,其生态服务功能价值的评估是促进林业可持续发展的科学基础。利用2015年东北地区不同林地类型遥感解译数据,评估森林生态系统服务功能价值及其空间格局。结果表明:东北地区森林生态系统服务价值总计24066亿元,各项服务价值排名依次是:生物多样性保护(9424亿元)、固碳释氧(7842亿元)、涵养水源(5469亿元)、保育土壤(1118亿元)、积累营养物质(123亿元)和净化大气环境(90亿元);东北三省森林生态系统服务价值均呈现由西到东的增长趋势,黑龙江、吉林两省东西部差异明显。研究结果对制定东北地区森林管理政策及建立可持续环境经济核算体系具有重要意义。

摘 要：
Forest ecosystem is a critical component of the terrestrial ecosystem,and its service value evaluation could offer a scientific basis for improving forestry sustainability as well as for policy making.This study applied the remote sensing interpretation data of the forest in Northeast China in 2015 to assess the ecosystem service value and figure out its spatial distribution pattern.The results showed that the ecosystem service value in Northeast China achieved 2.4066 trillion CNY,consisting of biodiversity protection(942.4 billion CNY),carbon fixation and oxygen releasing(784.2 billion CNY),water conservation(546.9 billion CNY),soil conservation(111.8 billion CNY),accumulation of nutrients(12.3 billion CNY),and purification of atmospheric environment(9.0 billion CNY).Spatially,the ecosystem service value showed an increasing trend from west to east,particularly between the eastern and western regions of Heilongjiang and Jilin provinces.The research results were of great significance to policy-making of forest resources management and establishing sustainable environmental accounting system in Northeast China.
