Study On Landscape Ecological Evaluation And Optimization Strategy Of Banshan National Forest Park In Hangzhou

With the acceleration of the pace of urban life and the increase of the pressure of study and work,more and more people need to relax.The activities of sightseeing and rest in forest parks in the city are accepted and loved by more and more people,and their landscape ecology is favored.This study takes Banshan National Forest Park in Hangzhou as the object.On the basis of comprehensive field investigation,GIS technology is used to analyze the data.Combined with the relevant theories of landscape ecological evaluation,the landscape ecological evaluation system of urban forest park is established,and the landscape ecology is comprehensively evaluated.The results are as follows :(1)The forest landscape tourism resources of Banshan National Forest Park in Hangzhou are diverse,with 8 categories,15 subcategories,21 basic types and 64 tourism resource monomers,including 2 special tourism resources,30 excellent tourism resources and 32 ordinary tourism resources.The forest land accounts for 87.1 % of the forest park,the forest coverage rate is 90.1 %,and the landscape ecological types of each functional block are rich.However,there are still obvious artificial traces and lack of influential natural landscapes in the current situation of landscape ecology.(2)The landscape ecological quality of Banshan National Forest Park in Hangzhou is excellent and the characteristics are obvious,among which the landscape nativeness is dominated by plateau areas,accounting for 87.46%.The moderate and low suitable areas of landscape suitability were equal,accounting for 45.96% and 46.07% respectively.The landscape sensitivity is mainly in the middle sensitive area,accounting for 71.16%.The landscape compatibility is dominated by high compatibility areas,accounting for 60.38%.The classification of landscape health is dominated by high health areas,accounting for 83.94%.(3)Using GIS software,the landscape ecological protection area of Banshan National Forest Park in Hangzhou is divided into three grades.According to the evaluation results,the scale,distribution and characteristics of each grade of landscape ecological protection areas show heterogeneity.Among them,the first-level landscape ecological protection area accounted for38.57%,mainly concentrated in the southwest area of the park,and its landscape sensitivity was relatively high;the secondary landscape ecological protection area accounted for 51.70%,with the largest area and the widest distribution,but its landscape suitability was relatively low.The third-level landscape ecological protection area accounted for 9.73%,mainly concentrated in the central area of the park.The landscape suitability was relatively high,but the landscape sensitivity and landscape compatibility were relatively low.(4)In order to realize the sustainable development of the landscape ecological status of Banshan National Forest Park in Hangzhou to the greatest extent,according to the characteristics of the three levels of landscape ecological protection areas,the landscape ecological optimization of the park can take the first-level reserve to protect the diversity of forest landscape,the second-level reserve to improve the visual richness of the landscape,and the third-level reserve to strengthen the connectivity of the park road network.
