| With the vigorous promotion and development of the construction of ecological civilization,forest parks and forest tourism have attracted more attention and like.As an important carrier of forest recreation function,forest parks have problems such as imbalance between development and protection in their continuous development and construction.Large-scale development of forest parks may damage the forest ecological environment and affect the protection of forest resources.Large-scale protection may limit the development of forest resources and affect the conversion of forest benefits.Forest landscape resources are objectively assessed by means of landscape ecological assessment,and the current status of forest resources,as well as the extent and value of which can be exploited,are analyzed to facilitate more reasonable protection and scientific development of natural resources such as forest parks.Based on the GIS software and landscape evaluation related theoretical basis,this paper constructs an index system for landscape ecological evaluation of forest parks,conducts a comprehensive evaluation of Wafangdian National Forest Park,proposes countermeasures and suggestions for its future development and protection,and compiles for the overall planning Provide scientific basis to realize the long-term development of ecological resources in forest parks.The main conclusions of the study are as follows:(1)Exploring the development background and current problems of forest parks,explaining the basic concepts of forest parks,forest tourism,landscape ecological assessment,and geographic information systems,and reviewing and summing up the application of landscape ecological assessment in the field of landscape architecture and GIS technology in landscape ecology Relevant research results in application and evaluation were selected,and 5indicators such as landscape suitability were selected as the criterion layer,and 16 evaluation indicators such as height and slope were selected according to the criterion layer,and a landscape ecological evaluation index system suitable for forest parks was constructed.(2)Combined with relevant theories and GIS technology,the landscape ecological assessment of the Longmentang area,Heilingshan Area,and Longtanshan Area of Wafangdian National Forest Park was conducted to determine the current status of forest landscape resources in each area.The originality of the forest park landscape was evaluated from three aspects:native landscape,semi-native landscape,and artificial landscape.The maps of the landscape originality of the three areas of the forest park were obtained.The visual sensitivity of the landscape was selected from the striking landscape,visual probability,and relative value of the forest park.Analyze the sensitivity of the forest park in terms of slope and relative distance.Aggregate cluster analysis is used to obtain a comprehensive hierarchical map of landscape sensitivity in three areas.Through weighted overlay analysis of four aspects of elevation,slope,aspect,and land use type,three are obtained.Comprehensive map of landscape suitability in the area;create a judgment matrix of recreational behaviors and landscape types,explain the compatibility of existing recreational behaviors in Wafangdian National Forest Park with different landscape types,and then obtain the map of landscape compatibility by classification;The three indexes of Yihua vegetation,landscape diversity and ecological resilience are used to understand the health status of the landscape,and the health degree grading map of the three areas of the forest park is obtained by weighted superposition.(3)Calculate the weight values of 5 indicators such as landscape sensitivity through the analytic hierarchy process to obtain the weight of landscape nativeness of 0.0884,the weight of landscape sensitivity of 0.2569,the weight of landscape suitability of 0.3205,the weight of landscape compatibility of 0.1270,and landscape The weight of health is 0.2072.Then through the weighted superposition of GIS software,comprehensive analysis was performed on the Longmentang area,Heilingshan area,and Longtanshan area of Wafangdian National Forest Park,and comprehensive protection maps for landscape ecological evaluation of the three areas were obtained.The Wafangdian National Forest Park is divided into three levels of protected areas,of which the area of the first level protected area is 691.26hm~2,accounting for 20.09%of the total area.The Longtanshan area is relatively large,and it is necessary to focus on protecting the area;the distribution range of the second level protected area It is relatively large,with an area of 1751.85hm~2,accounting for 50.91%of the total area.It is mainly concentrated in the Longmen Tang area,and the development and construction of this area should be restricted.The tertiary protection area is mainly distributed in the Heilingshan area,which has an area of 997.70hm~2,accounting for 29.00%of the total area,forest resources can be properly developed and utilized.Finally,through analysis and comparison of the evaluation results of each indicator in the three areas of the forest park,the advantages and disadvantages of forest resources in each area are clarified,and countermeasures for future development and protection of the three areas of the Wafangdian National Forest Park are proposed.The landscape resources in the Heilingshan area can be developed and utilized to a higher degree,and the landscape resources in the Longtanshan area are protected to a higher degree.Achieve the maximum sustainable landscape resources of Wafangdian National Forest Park and provide a certain reference for the planning and construction of other forest parks in Liaoning Province. |
