Abstract
In this study, Analytic Hierarchy Process was used to construct the environmental safety evaluation level of physical spatial layout, social environment guidance and security technical means as the evaluation criteria. In addition, using the complete evaluation index system constructed after the weight value is given, the environmental safety of the four research object urban parks in Fuzhou city is evaluated, and the comprehensive evaluation grade is divided. The results show that: 1) The each evaluation index in the criterion layer is ranked from high to low as physical spatial layout (0.4097), security technical means (0.3244), social environment guidance (0.2659); 2) In the factor layer, the top 5 places in the overall weight value order of the evaluation index factors are CCTV monitoring (0.1040), organization of social activities (0.0840), lighting (0.0827), plant furnishing (0.0806), mixed crowd (0.0743); 3) In terms of environmental safety construction of the four research object urban parks in Fuzhou city, the comprehensive evaluation results are that Wenquan park is in Grade I (Very Good), Xihu Park and Chating Park are in Grade Ⅱ (Good), and Wangzhuang Nanhu Park is in Grade III (Average).
