摘要:
[目的]研究和评估不同生态区主要生态系统服务功能和价值的变化,为区域的生态保护、自然资源核算和生态补偿等决策提供理论依据和参考。[方法]基于1980,2000和2015年的土地利用数据,采用单位面积价值当量因子法构建土地利用二级分类当量表,计算3个时段河北省各生态环境支撑区的生态系统服务价值。[结果]①1980-2015年河北省土地利用的变化主要表现为农田转为城乡建设用地,其他生态用地转为农田的趋势。②以2015年的价格计算,1980-2015年河北省总生态系统服务价值的年平均值约为3.56×1011元。③1980-2015年河北省生态系统服务价值减少约7.00×109元。④单位面积生态系统服务价值最高的生态区为燕山-太行山,其次是坝上高原、海域海岸、京津保,最低的为低平原区。⑤1980-2015年京津保生态区生态系统服务价值下降幅度最大为28.1亿元,降低15.0%。[结论]2000年后的生态环境建设对恢复和提升河北省生态系统服务功能发挥了重要作用。

Abstract:
[Objective] The change of ecosystem service value was estimated in order to provide references for major ecosystem service functions of decision-making in ecological protection, ecological regionalization, natural resources accounting and ecological compensation.[Methods] The method of unit area value equivalent factor was used to construct the secondary classification equivalent table of land use, and the ecosystem service value of each ecological environment support area in Hebei Province was calculated with land use data in 1980, 2000, and 2015.[Results] ① During 1980-2015, land use change happened mainly from cultivated land to construction land, and from other ecological land use types to cultivated land. ② The annual average value of total average ecosystem service value during 1980-2015 was 3.56×1011 yuan based on the price in 2015. ③ The total ecosystem service value of of Hebei Province was reduced by 7.00×109 yuan from 1980 to 2015. ④ The ecological environment support areas with the highest ecosystem service value per unit were Yanshan-Taihangshan, followed by Bashang, Hai'an-Haiyu, Beijing-Tianjin-Baoding and low plain. ⑤ Ecosystem service value of Beijing-Tianjin-Baoding decreased 15.0% from 1980 to 2015, which was the highest among different ecological area.[Conclusion] Ecological construction after 2000 played an important role in recovering and enhancing ecosystem service functions of Hebei Province.
