中文摘要：

采用可变步长的两步移动搜索法，以福建省福州市为典型案例，以居民点（普查小区）为分析单元，对各居民点入园空间可达性进行了测算，并与传统的两步移动搜索法进行对比分析，综合判别学前教育资源空间分布特点。研究表明：福州城区入园可达性总体情况并不理想，仅有少数地区、少量人群可以获得较好的幼儿园空间的可达性。入园可达性在地理空间上呈现出多中心结构，高可达性地区主要分布在市中心并在城市周围零星分布，边缘乡镇特别是除西部以外的乡镇地区缺教明显，入园可达性在城区内部差异较大，幼儿园资源过剩地区和稀缺地区呈两极分化的格局。可变步长的两步移动搜索法能更为客观有效地对幼儿园的布局状况进行评价。而传统方法有一定的夸大作用，且降低了内部的差异，在一定程度上掩饰了幼儿园资源分布的不公平现象。

英文摘要：

Entering the nearby kindergarten is the important content in preschool education planning and give the research on spatial accessibility to kindergarten. This paper is conceming on the spatial accessibility to kindergarten by using two access measures including the popular two-step floating catchment area （2SFCA） method and variable catchment sizes for two-step floating catchment area method （V2SFCA）, thus to capture the interaction between kindergarten and settlement ,then to compare the results of the two methods and get a integrative estimate of spatial distribution of preschool educational resources in Fuzhou central urban area. The results indicated that the overall accessibility of Fuzhou City＇s kindergarten distribution is not ideal, and only a minority of the region, a small number of people can get a good kindergarten accessibility. As for the geographical space of kindergarten accessibility, the west region is much better than the east region, and north slightly better than the south, demonstrating a polycentric structure at the same time. The high ac- cessibility areas are mainly distributed in the center of the city and scattered around the city.
