摘要：当前，中国经济处于转型发展阶段，农村也必将转变发展的方式，乡村振兴对于改善乡村生态环境及带动乡村旅游的发展具有重要意义。针对云南乡村旅游的发展存在的部分地区旅游资源挖掘深度不足、旅游资源同质化频繁且缺乏相应特色以及部分地区旅游发展缺乏统筹规划等问题，提出了以保护乡村生态环境先行，推动乡村旅游可持续发展;以注重内涵式发展先行，转变乡村旅游的发展方向;以加强规划制度先行，统筹推进乡村旅游发展等推动云南乡村旅游可持续发展的对策。

Abstract：In order to study the changes of physicochemical indexs and antioxidant activities of Apple Jiaosu during natural fermentation process and clarify the health function mechanism of malenzyme， the dynamic changes of the soluble solids content， pH， total acid content， ethanol content， DPPH free radicals， hydroxyl free radicals， superoxide anion free radicals， and ABTS free radicals were investigated. The results showed that the soluble solid content and pH value decreased gradually with the extension of fermentation time. After 90 days of fermentation， the soluble solid content dropped to 4.5 °Brix and the pH dropped to 3.06， which were reduced by 70% and 32% respectively compared with the initial stage of fermentation. The total acid content gradually increased， increased to 42.9 g/L after 90 days， and increased 98%. the ethanol content first increased and then decreased， it was achieved to 1.0 g/L， after 90 days， and complied with regulations of QB/T5323-2018. The antioxidant activities were reached the better in fermentation to 75～90 days. The free radical scavenging rates of DPPH and hydroxyl were reached to 86.16% and 79.03% after 90 days， and increased 44.5% and 45.53%， respectively. The superoxide anion and ABTS were peaked at fermentation 75 days（65.06% and 69.04%， respectively），which were increased 39.12% and 46.47%. The study would provide some theoretical basis for further elucidating the health function mechanism and comprehensive development of Apple Jiaosu.

隨着经济的快速增长，中国人民的生活水平也不断的得到提高，越来越多的人在实现收入增长的同时也不断追求精神上的享受，旅游成为了人们提升精神享受的重要选择，旅游方式与内涵也不断地呈现出多样化趋势。2020年国内旅游的游客数量达到63.25亿人次，较2019年增长了4.32亿人次。其中，城镇居民游客总人数53.26亿人次，占全国游客总人数的79.63%，成为国内旅游举足轻重的力量，在推动国内旅游事业发展中具有重要意义[1 ]。

伴随着乡村振兴战略向纵深推进以及农业的转型升级，我国的旅游市场特别是乡村旅游市场也随之实现转型，乡村旅游进入了新的发展阶段，也成为促进地区经济发展的重要推动力量，成为联系城市与农村、城镇居民与农村居民之间的桥梁[2 ]。……
