Urban parks,as an ideal recreational place,are getting increasingly important for the urban residents in our society.The easy reachability of a park is another important index apart from the other two indices of park area and the number of parks.The reachability analysis based on GIS and AHP can better evaluate the reachability in terms of the spatial position and the residents’psychological distance in a reasonable and obj ective manner,which can serve as a reference method and the theoretic ground.Our findings show that the parks of Fuzhou are reasonably distributed with good reachability,but service gaps remain to be filled in certain districts;Compared with the method of direct assignment of service scopes,the weighted Thiessen Polygon can better reflect the reachability of Fuzhou’s parks.%城市公园作为居民的主要活动游憩场所，对于现代社会有重要的意义。公园本身能否让游客容易快捷地进入，是除了公园面积、个数之外的重要评价指标。基于 GIS以及 AHP评价方法的公园可达性分析，能够合理客观的评价福州市城市公园在空间位置上的可达性以及城市居民心理上可达性，为合理的规划城市提供参考方法及理论依据。结果表明：福州市的各公园分布较为合理，大部分具有良好的可达性，但仍然存在一定区域的服务空白；相较直接划分公园的服务范围，加权泰森多边形能够更好的反映福州公园的可达性。
