Study On The Evaluation Of Urban Marina Space Vitality Based On Multi-Source Data

In the coastal city’s rapid economic development today,the people’s living standards are rising,in the process of creating a high-quality urban environment,the coastal space to enhance the vitality of into can not be underestimated.A richly attractive coastal space can effectively attract urban coastal residents to participate in various outdoor activities,not only to improve physical quality,but also to increase the economic and vitality of the coastal space,so the study of the vitality of the coastal space is essential.This paper takes the section from Shapowei to Huangcuo on the traffic circle road of Xiamen City as the research object,and uses Python to crawl the Baidu heat map data to explore the spatial and temporal distribution and changes in the vitality of the coastal space of the traffic circle road on different typical dates;uses Arc GIS10.8 software to obtain POI data,OSM data and NDVI data and other multi-source data to quantify the location,spatial characteristics,traffic and facilities of the coastal space.Subsequently,the data were then imported into SPSS26 software to do Pearson correlation analysis and multiple linear regression analysis on the coastal spatial vitality phenotypes.The research results show that the global distribution of the coastal space heat is uneven,only a small part of the coastal space has relatively high heat value,and most of the remaining areas have low heat value;from the trend of the single day time average heat value of each typical day,the daily 12:00 noon and 18:00 in the evening form two relatively high peak points,the average heat value of holidays is much higher than that of rest days and weekdays;for the vitality For the intensity of vitality,the intensity of vitality in the western part of the coastal space of the study area is significantly higher in the west and lower in the east,and the relationship between holidays and rest days is greater than that of rest days;for the stability of vitality,it is mostly distributed in the eastern part of the study area,and the relationship between holidays and rest days is slightly greater than that of rest days;the analysis of the four types of vitality shows that there are relatively few high-intensity-high-stability areas,relatively more high-intensity-low-stability areas,and relatively more low-intensity-high-stability areas.The relative distribution of high-stability areas is the most;the relative distribution of low-intensity-low-stability areas is the least.The correlation analysis of the selected spatial environmental indicators with the vitality intensity and vitality stability shows that the location centrality,attraction density,road network density,accommodation service facility density and commercial service facility density have a positive impact on the vitality intensity,but have a certain inhibitory effect on the vitality stability;the land use mixture has a negative impact on the vitality intensity,but has a certain promotion effect on the vitality stability;Plant coverage,bus stop coverage,sports service facility density,cultural service facility density and medical service facility density have no significant effects on vitality intensity and vitality stability.On the basis of the above analysis and conclusions,relevant vitality enhancement strategies are proposed,with a view to contributing to the construction of future urban coastal space vitality.
