Toughness Evaluation and Functional Enhancement of Disaster Prevention and Avoidance of Urban Park Green Space
Urban park green space effects a critical role in addressing adverse climate and uncertain disaster events.Thus,it is exceedingly significant for evaluating and analyzing the disaster prevention and resilience ability of urban parks and for enhancing their disaster prevention function.Using ArcGIS software,the study analyzed the kernel density pertaining to the spatial distribution of park green space in Haigang District,Qinhuangdao City.The results indicated that there is a spatial mismatch between park green space resources and population distribution in Haigang District.If Tanghe Park is considered as the research object,the Fuzzy Delphi method and analytic hier-archy process are utilized to construct an evaluation index system,and 13 indexes from three dimensions,namely safety,accessibility,and infrastructure were evaluated to analyze the problems pertaining to the disaster-prevention resilience design of the park.Subsequently,the following corresponding strategies are proposed:optimizing the human-oriented spatial layout and building a nested disaster prevention network system;strengthening the park's multi-disaster comprehensive defense capability and stabilizing the ecological security function;increasing the safe and effective escape area and enhancing the park's functional space layout;and replenishing emergency infra-structure resources and establishing dynamic emergency management plans.
