Study On The Identification And Protection Of Coastal Landscape Style From The Perspective Of Character Assessment

Coastal landscape protection is one of the effective ways to improve the environmental quality of coastal space and build a beautiful city.Under the territorial and spatial planning system,it is the main purpose of this article to solve the real problem of the lack of coastal landscape features under the long-term land-dominant development framework,explore the technical support for the evaluation methods of coastal landscape elements,and propose targeted coastal landscape protection strategies.First of all,it elaborates from three aspects: the lack of coastal character under the framework of land led development,the new requirements of beautiful city construction for style improvement,and the coastal space management and control under the construction of land space planning system,The necessity and feasibility of coastal landscape style recognition and protection from the perspective of character assessment are clarified.Based on the theory of the relationship between man and the sea,it analyzes the relationship between man,land and sea,and analyzes the formation of ocean image landforms and the style shaping of human activities.Finally,through the interpretation of landscape character assessment methods,this paper explores the support of landscape character assessment to identify coastal landscape style.Secondly,it constructs the framework of character assessment to identify the coastal landscape style.On the basis of summarizing and comparing the landscape character assessment and the composition of landscape style elements,this study proposes to classify the coastal landscape style elements from the perspectives of ocean impact,shoreline character,hinterland impact and aesthetic perception.This paper introduces the Visual Resource Mapping method to define the coastal landscape from the visual perception level.Finally,a coastal landscape character recognition method based on principal component clustering analysis is proposed.Then,according to the framework of the above character evaluation and identification of coastal landscape style,this paper makes an empirical study on the coastal landscape style of Dalian city.At the city scale and the main city scale,the visual perception scope of the study area is defined from the perspectives of "looking at the sea from the land" and "looking at the land from the sea",respectively.Combined with the coastal landscape elements determined in the third chapter and the current situation of Dalian landscape,the coastal landscape elements of the two scales are extracted.The principal component cluster analysis method is used to identify the coastal landscape types,and the e Cognition image processing software and manual adjustment method are used to adjust the boundary of coastal landscape zoning.Finally,this study puts forward the principles and strategies of coastal landscape protection based on character recognition.It includes three principles: ecological protection,rational utilization,land and sea co-ordination,element integration,multi-layer nesting and hierarchical management and control.From the three scales of region,city and urban area,the coastal landscape area is managed and controlled at different levels;Based on The mapping of sea visibility from land and the mapping of land with sea views,the shape and visual corridor of the coastal landscape area were optimized from the perspective of landscape visual perception.The restoration and construction of coastal landscape elements are carried out from four aspects:mountain and sea pattern protection,coastal shoreline restoration,coastal space construction and energy landscape layout.
