摘要:生态旅游服务价值作为生态系统生产总值（Gross Ecosystem Product，GEP）的重要组成部分，是生态产品价值实现的重要途径。以衢州市柯城区"一村万树"实施区为研究区域，采用国际上普遍认可的旅行费用区间法（Travel Cost Interval Analysis，TCIA）进行了问卷调查，开展了生态旅游服务的价值核算；同时基于计量经济学原理构建了游客随机效用模型（Random Utility Model，RUM），探究了不同自然地理属性对游客生态旅游选址决策的影响。结果表明：（1）2018年"一村万树"实施区的生态旅游服务总价值约19.29亿元，单位面积生态旅游价值量为8.37万元/hm²；（2）2018年"一村万树"实施区的游客人均游憩价值为713.89元，只占整个柯城区人均游憩价值（1204.58元）的59.3%，说明其还有较大的生态产品价值实现提升空间；（3）柯城区游客人均游憩价值远高于当地文化旅游局提供的621.80元的旅游人均消费支出，说明游客时间成本和消费者剩余蕴含了丰富的潜在价值，需要在评估时予以考虑；（4）随机效用模型结果显示，目的地旅行费用与游客访问呈负相关，森林和湿地面积均与游客访问呈正相关，且湿地的相对贡献远高于森林。研究结果对"一村万树"实施区有针对性地进行生态保护、管理和开发具有指导意义，对提高GEP核算的准确性和探索生态产品价值实现的机制具有借鉴意义。



Abstract:As an essential component of the Gross Ecosystem Product (GEP), ecotourism service value is an important value realization pathway for ecosystem products. Taking the "One Village Ten Thousand Trees" implementation area at Kecheng District, Quzhou City as our study area, we adopted the internationally recognized travel cost interval analysis (TCIA) to conduct the questionnaire survey, and carried out the value accounting of ecotourism service. Meanwhile, based on the principle of econometrics, we constructed the random utility model (RUM) of tourists, and explored the impact of different natural geographical attributes on tourists' ecotourism location decision. Our results show that (1) the total economic value of ecotourism service in the implementation area of "One Village Ten Thousand Trees" was approximately 1.93 billion yuan and the value of ecotourism service per unit area was 83700 yuan/hm² in 2018. (2) In 2018, the per capita recreational value of tourists in the "One Village Ten Thousand Trees" implementation area was 713.89 yuan, accounting for 59.3% of that of Kecheng District (1204.58 yuan), indicating that there is still a large room for improvement in the value realization of ecosystem products. (3) Per capita recreational value of tourists in Kecheng District was much higher than the per capita tourist consumption expenditure of 621.80 yuan reported by the Bureau of Cultural Tourism of Kecheng, indicating the large potential of tourists' time cost and consumer surplus, which needs to be taken into account in the assessment. (4) The random utility model showed that the travel cost had a negative association with tourists' visit to the destination, while the area of forest and wetland each had a positive correlation; moreover, the relative contribution of wetland was much higher than that of forest. Our study helps to promote the ecological protection, management, and development of the "One Village Ten Thousand Trees" implementation area at Kecheng and beyond. Our study also helps to improve the accuracy of GEP accounting and explore the value realization pathway for ecosystem products.
