摘要:文章基于百度与谷歌数据源获取与儿童绿地相关图像,运用图像数据研究的新思路进行分析,结果表明:1)儿童行为与绿地密切相关,百度结果显示其紧密程度(高于60%)小于谷歌紧密程度(高于81%)。2)百度结果显示儿童绿地空间较单一,儿童在绿地空间的行为体现为常规(8.05%)>集体(2.01%)>挑战(0.67%);谷歌检索结果显示儿童行为较为多样,表现为集体(27.52%)>常规(15.43%)>挑战(12.08%)。最后,文章在图片内容分析的基础上,从基于感官系统提升绿地特征的多样性、基于儿童行为类型提升绿地空间的多元性、促进生物多样性增加绿地互动的可能性3个方面提出儿童绿地品质提升策略。

Abstract:This paper obtains the images related to childrens green spaces through Baidu and Google for the study based on the new ideas of image data based green space research. We found after the analysis: 1) Childrens behaviors are closely related to green spaces, but the closeness from the search results with Baidu (above 60%) is less than that with Google (above 81%); 2) Baidus search results show that childrens green spaces are relatively unitary, and childrens behaviors in green space include regular activities (8.05%)> collective activities (2.01%)> creative activities (0.67%), while the Google search results include multiple types of behaviors as follows: collective activities (27.52%)> regular activities (15.43%)> creative activities(12.08%); 3) This paper proposes the strategies for improving the quality of childrens green spaces from three aspects: sensory system, childrens behavior types, biodiversity.

城市綠地对公众身心健康有重要的影响[1]。2016年,我国审议通过了“健康中国2030”规划纲要,明确强调营造绿色安全的健康环境和突出解决好妇女、儿童等重点人群的健康问题[2]。为儿童和青少年提供健康的环境已成为新城市建设的必要部分[3]。本研究重点关注影响儿童行为的绿地空间(文中统称为“儿童绿地”)。关于儿童绿地的已……
