基于网络文本分析的环城生态区游憩空间使用后评估——以成都市锦城公园为例

Post-use Evaluation of Recreational Space in the Ecological Zone around the City Based on Network Text Analysis——A Case Study of Jincheng Park in Chengdu

环城生态区的游憩空间作为城市公共空间的有力补充,表现出独特的空间特性。以成都市环城生态区示范项目锦城公园为研究对象,通过网络文本分析(高频词汇提取、语义图分析、高频词汇正负情感分析)及ASEB矩阵栅格分析等方法对锦城公园游憩空间进行使用后评估,总结出4项积极要素及4项消极要素,并对消极要素提出改善建议。通过积极要素表征与消极要素改善建议,为环城生态区规划设计的进一步更新与优化策略提供参考借鉴。

As a powerful supplement to the urban public space,the recreational space of the ecological zone around the city shows its unique spatial characteristics.This paper takes Jincheng Park as the research object,and evaluates the recreational space of Jincheng Park by means of network text analysis(high frequency vocabulary extraction,semantic map analysis,positive and negative emotion analysis of high frequency vocabulary)and ASEB matrix grid analysis.Four positive factors and four negative factors are summarized,and suggestions for improvement are put forward.Through the positive elements representation and negative elements improvement suggestions,this paper provides reference for the further renewal and optimization strategy of the planning and design of the ecological zone around the city.
