皖南查济古村落旅游净碳排放估算与减碳增汇研究

Research on Path from Evaluation of Net Carbon Emission,Carbon Emission Reduction to Carbon Sink Increase for Rural Tourism Destinations: Exemplified by Zhaji Old Village in Southern Anhui

当前,乡村旅游地已成为人们外出旅行的重要选择。一方面,乡村旅游地消耗碳基能源、产生旅游垃圾,排放出CO_2;另一方面,乡村地区陆地生态系统中蕴藏着丰富的碳汇资源,而乡村旅游发展客观上保护并提升了旅游地系统中的碳汇和生态服务功能。从源、汇两端出发,构建乡村旅游地的净碳排放估算框架,集成估算方法,估算皖南查济古村落2015年净碳排放为负值,表明旅游业排放的CO_2低于旅游地系统碳汇资源吸收的CO_2量。通过定量分析,认为旅游食宿接待能源消耗与旅游垃圾焚烧碳排放是主要碳源,林地覆被和农业作物是主要碳汇。从教育、管理、规划等方面提出减碳增汇的对策。

With tourists＇ quest for good environment quality,the choice of rural tourism destinations became important consideration for travelers. On the one hand,the development of rural tourism consumes carbon-based energy brought solid waste and emit CO2. On the an other hand,terrestrial ecosystems in rural areas contained abundant carbon sink and the development of rural areas,objectively speaking,was beneficial for the protection and promotion of carbon sink in tourism system. Based upon this consideration,this paper started from the two-way angle to construct an evaluation framework of net carbon emission in rural tourism destinations,synthesized different ways of evaluation,and clarified specific theoretical evaluation basics. With the case study of old Zhaji village in southern Anhui,according to the statistics from field survey,it was estimated that the net carbon emission in old Zhaji village in 2015 was below,which meant that CO2 carbon emission in this tourism system was below CO2 absorption,and which was rendered carbon sinks of the atmosphere. From quantitative analysis of the features of carbon emission and absorption in old Zhaji village,it was concluded that tourism accommodation and refuse burning account mainly for carbon emission while forest vegetation and crop planting contributed most to carbon absorption. With the purpose of reducing carbon emission and increasing carbon sink,such different measures could be taken as follows： Education,management and regulations.
