Risk Assessment Of Mosquito Breeding In Urban Parks

As public health problems in cities continue to intensify,attention to health has become an important development trend in the field of human habitat in China.As a major outdoor venue for urban residents,urban parks play a key role in maintaining and improving the public health of citizens,yet the mosquito problem,which is closely linked to the landscape and human health,has not received sufficient attention.On the one hand,mosquitoes,as one of the vectors of disease transmission,may pose a threat to human health by biting humans;on the other hand,water bodies and plants,as important landscape components of urban parks,may create a suitable environment for mosquito breeding.Therefore,it is important to study how to quantify the risk of mosquito breeding in urban parks and discuss how to control mosquito breeding at the source through landscape planning to promote public health.In this study,the landscape space types of Zhongshan Park in Wuhan City were divided into 3 major categories and 10 subcategories through field research,and 12 typical landscape space types were selected as sampling points;female mosquito density measurement experiments were conducted on the 12 sampling points in July-August2022,and the temperature,humidity and wind speed data were recorded at that time;the obtained arbor data were then used to combine with Arc GIS The relationship between the spatial type of urban park landscape,landscape composition factors and physical environment data and mosquito density was explored by using analysis of variance and correlation analysis in SPSS25.0;based on the above conclusions,an urban park mosquito breeding risk assessment model was established by combining the AHP hierarchical analysis method and applied to Wuhan.Based on the above findings,a mosquito breeding risk assessment model was established in the urban park combined with AHP hierarchical analysis and applied to Zhongshan Park in Wuhan City.The main conclusions of the study are:(1)there is a correlation between the type of urban park landscape space and mosquito density,and the different landscape types affect the mosquito density to a certain extent;(2)among the landscape composition factors,tree cover,aquatic plant cover and the proportion of water bodies are significantly positively correlated with female mosquito density,and the degree of hard pavement cover is significantly negatively correlated with female mosquito density;(3)there is no correlation between the temperature,humidity and mosquito density recorded in this study,(3)there is no statistically significant correlation between temperature,humidity and mosquito density recorded in this study,wind speed and female mosquito density showed a significant negative correlation;(4)the possibility of mosquito breeding in common landscape water bodies such as rockery,shallow water reservoirs;(5)the risk map of mosquito breeding in Zhongshan Park in Wuhan,and the high risk areas were analyzed;(6)finally,according to the above conclusions,the principles of mosquito prevention and control in urban parks were proposed,and from macroscopic zoning control as well as microscopic control.(6)Finally,based on the above findings,the principles of mosquito prevention and control in urban parks are proposed,and mosquito prevention and control strategies in urban parks are proposed from two aspects: macro zoning control and micro landscape design initiatives.
