Understanding the value of ecosystem services is imperative for the welfare of current and future generations. Anxi town is situated within the mountainous terrain of Fujian province, China and characterized by a diverse range of ecosystems encompassing forests, rivers, and mountains. These ecosystems offer a wide range of ecosystem services. The value of ecosystem services has been declining in the county for the past twenty-years. However, limited is known on the spatial changes and factors affecting the value of these Therefore, current study assessed the spatial changes in the value of ecosystem services (provisioning, regulating, supporting, and cultural) in 24 townships situated in the county for three time periods, i.e., 1999, 2009, and 2019 and factors affecting these services. The results revealed that annual decline in the value of ecosystem services was higher in 1999-2009 than 2009-2019. Longjuan, Xianghua, Gande, Futian, Changkeng, Xiping, Taozhou and Huqiu townships observed the highest annual decline in the value of ecosystem services ranging from 20.1 to 68.1 million yuan. The GWR model indicated that vegetation index had the highest impact on the value of ecosystem services in the county. Overall, the value of ecosystem services was negatively correlated with the urbanization rate and distance from the road with some exceptions, whereas altitude had a positive impact. All townships (except Xianghua, Futian, and Taozhou) had negative values for water supply services. Hence, water supply is a significant ecological issue in the county. It is concluded that tea farmers in the county should be educated about water and soil conservation, investment should be done in conservation measures, regional ecological environments should be protected, and ecological tea planting techniques should be developed in the county to halt further decrease in the value of ecosystem services.
了解生态系统服务的价值对于当代和后代的福祉至关重要。安溪县位于中国福建省的山区，拥有包括森林、河流和山脉在内的多种生态系统。这些生态系统提供了广泛的生态系统服务。在过去二十年中，该县生态系统服务的价值一直在下降。然而，对于这些服务价值的空间变化和影响因素却知之甚少。因此，本研究评估了该县24个乡镇在1999年、2009年和2019年这三个时间段内生态系统服务（供给、调节、支持和文化）价值的空间变化以及影响这些服务的因素。结果显示，1999 - 2009年生态系统服务价值的年下降幅度高于2009 - 2019年。龙涓、祥华、感德、福田、长坑、西坪、桃舟和虎邱等乡镇的生态系统服务价值年下降幅度最大，在2010万元至6810万元之间。地理加权回归（GWR）模型表明，植被指数对该县生态系统服务价值的影响最大。总体而言，生态系统服务价值与城市化率和距道路的距离呈负相关，但有一些例外情况，而海拔则有积极影响。所有乡镇（祥华、福田和桃舟除外）的供水服务价值均为负值。因此，供水是该县一个重要的生态问题。研究得出结论，该县应教育茶农进行水土保持，投资于保护措施，保护区域生态环境，并在该县发展生态茶叶种植技术，以阻止生态系统服务价值的进一步下降。
