Landscape quality evaluation of Hefei Binhu National Forest Park based on GIS
[Objective]Evaluate the landscape quality of forest parks,provide a basis for forest park planning and scientific landscape layout,and scientifically improve the ecological environment and landscape quality of forest parks.[Method]Based on GIS evaluation methods,a forest park landscape quality evaluation index system was constructed from four aspects:landscape aesthetic value,landscape ecological structure,landscape culture implication,and landscape visibility.The landscape quality of Hefei Binhu National Forest Park was evaluated and mapped.[Result]1)The proportion of area in each level of landscape aesthetic value was ranked as high(52.3%),medium(31.2%),and low(16.5%);The proportion of area in each level of landscape ecological structure was ranked as high(51.3%),medium(34.5%),and low(14.2%);The proportion of area in each level of landscape culture implication was ranked as high(42.6%),medium(36.3%),and low(21.1%);The proportion of area in each level of landscape visibility was ranked as low(69.7%),medium(20.8%),and high(9.5%).2)The landscape quality of Hefei Binhu National Forest Park was ranked as medium(46.6%),high(41.2%),and low(12.2%)in terms of area proportion.3)The high level areas of landscape quality in Hefei Binhu National Forest Park were mainly located in the southern part of the forest park,and the area gradually decreased as the distance from the tourist road increases.4)Based on the evaluation results,four goals were proposed:aesthetic design,natural ecology,cultural highlight,and good visual experience.Three design suggestions were provided to enrich plant combinations,create interesting terrain,and unify architectural styles,in order to improve the landscape quality of Hefei Binhu National Forest Park.[Conclusion]By analyzing the digital elevation model data of Hefei Binhu National Forest Park in 2021,the landscape quality and distribution of the forest park are evaluated,providing scientific basis for the landscape planning of Forest Park and achieving the ecological protection goals of the forest park.
