摘　　要：以北川小寨子沟自然保护区为研究区域,在资料搜集和野外调查的基础上,从涵养水源、水土保持、固碳制氧、净化环境4个方面入手,选取蓄水效益、固土效益、固定CO_2效益等8个评价指标,构建了1个包含总体层、系统层、指标层的生态效益评价体系。基于以上评价体系,利用生态效益核算方法分别对8个指标进行生态效益核算。结果表明,北川小寨子沟自然保护区生态效益显著,对当地环境具有重大的贡献。With Xiaozhaizigou nature reserve in Beichuan as the research area,1 ecological benefit evaluation system including the overall level,the system level and the index level was constructed based on the data collection and field investigation. It started from the 4 aspects of water conservation,soil and water conservation,carbon fixation and oxygen production,environmental purification. 8 evaluation indexes were selected such as water storage benefit,soil consolidation benefit,fixed CO_2 benefit and so on. Ecological benefit accounting of these 8 indexes was carried out by the method of ecological benefit accounting based on the above evaluation system. Results showed that the ecological benefit of Xiaozhaizigou nature reserve was significant,and it had great contribution to the local environment.
