摘　　要：为深入探讨上海市公园建设及其可达性的时空发展特征,基于上海市公园建设数据与人口数据,综合考虑公园空间分布、面积、类型等多重因素,分析上海市公园建设趋势;针对高密度城区,基于2000年、2010年、2020年3个不同时间节点,在500 m栅格精度下,计算步行范围内人均公园面积,评价公园可达性。结果表明:1)截至2020年底,上海市共有406座城市公园,人均公园个数为0.163个/万人,人均公园面积约为1.47 m^(2)/人。2)建设用地趋紧背景下,公园建设重心由内环移向外环,新建公园平均面积先增加后减少。3)公园建设与高密度城区匹配程度先降低后提升,即2000年约24%的高密度城区1 km范围内缺少城市公园,可达性欠佳;2010年约为38%;2020年为21%左右。4)中环外高密度城区仍有公园步行可达性欠佳的区域,需在未来规划中予以重视。In order to discuss in depth the construction and accessibility of parks in Shanghai,this study analyzes the trends of park construction in Shanghai considering multiple factors such as spatial distribution,area and type of parks based on the data of parks and population.For high-dense urban areas,the park area per capita within walking distance is calculated at the grid accuracy of 500 m in 2000,2010 and 2020,in order to evaluate park accessibility.The results show:1) By the end of 2020,there were 406 urban parks,or 0.163 parks per 10,000 persons,and the park area per capita was about 1.47 m^(2)/person;2)With limited construction lands in Shanghai,the construction sites for parks shifts from the inner ring area to the outer ring area,and the average area of new parks first increases and then decreases;3) The level of matching between park construction and high-dense urban area first decreases and then increases.In 2000,about 24% of high-density urban areas had no urban parks within 1 km,which indicates a lower accessibility;in 2010 and 2020,the proportions were about 38% and 21%,respectively;and 4) The park accessibility in high-density urban areas outside the middle ring is still poor,and more attention will need to be paid to in the park planning.
