| 湖泊公园是城市蓝绿空间的重要类型之一，开展湖
泊公园生态系统文化服务感知量化研究，对保护生态环境和提
升游憩空间质量具有重要意义。以武汉市8个典型湖泊公园为
研究对象，爬取公园网络评论数据，利用LDA主题模型挖掘
潜在主题，结合社会网络分析法和情感分析模型，并对比问
卷调查结果，探讨湖泊公园生态系统文化服务感知差异。结果
表明：湖泊公园生态系统文化服务公众感知维度有休闲娱乐、
审美体验、运动健康、社交互动、历史文化和科普教育；主导
服务类型是休闲娱乐和审美体验，而科普教育是最不易被感知
的；公园可达性、周边文化建设、园内基础设施及自身特色是
影响感知频率和满意度的主要因素；不同年龄段人群的使用需
求和活动类型差异对感知满意度有一定影响。因此，未来湖泊
公园的建设可在科普主题活动举办、特色湖泊文化景观、公园
配套服务设施、生态环境治理等方面进一步完善，并关注多年
龄段人群需求，从而提升公园服务品质。 |

| A Study on Public Perception of Cultural Ecosystem Services in Lake Parks Based on Latent Dirichlet Allocation Model |

| Abstract: |
| : Lake parks are one of the important types of urban bluegreen spaces, and it is important to carry out quantitative research on
the perception of cultural ecosystem services in lake parks to protect
the ecological environment and improve the quality of recreational
spaces. This study crawled the online review data of eight typical
lake parks in Wuhan, used the LDA theme model to mine potential
themes, combined with social network analysis method and sentiment
analysis model, and compared the questionnaire results to explore
the differences in perceived cultural ecosystem services in lake parks.
The results show that: the public perception dimensions of ecosystem
cultural services in lake parks are recreation, aesthetic experience,
sports and health, social interaction, history and culture, and science
education; the dominant service type is recreation and aesthetic
experience, with science education being the least perceived; the main
factors affecting the frequency of perception and satisfaction are the
accessibility of the park, the surrounding culture, the infrastructure
of the park and its own characteristics; differences in usage needs
and types of activities for different age groups have an impact on
perceived satisfaction. Therefore, the future construction of lake park
will be further improved in terms of holding science-themed activities,
special lake cultural landscapes, park supporting services and facilities,
ecological and environmental management, as well as focusing on the
needs of multi-age groups, thus enhancing the quality of park services |
