The Study On Visual Quality Evaluation Of Rural Forest Landscape

Since the proposal of the objective of beautiful countryside in 2013,China has paid more and more attention to the construction of rural ecological landscapes,greening and beautification of rural landscapes,environmental protection and comprehensive management.As an important part of landscape ecological construction,rural forest visual landscape construction can promote the development of beautiful villages and it can be an important endogenous force for the successful construction of beautiful villages.It is of great significance for the promotion of the construction of beautiful villages to scientifically evaluate the visual quality of forest landscapes and determine a reasonable rural forest landscape structure.Based on a large amount of reading and summarizing domestic and foreign theoretical methods and related research results,this article proposes that rural forest landscape visual quality includes three parts: current situation of landscape quality,visual sensitivity and visual absorption capacity.Meanwhile,it establishes a comprehensive evaluation process and system of forest landscape visual quality,and it also expands the definition,indicators and standards of visual quality evaluation.In this article,the abstract visual evaluation is extended to the level of quantification by applying the combination of GIS spatial analysis technology and conventional evaluation methods.At the same time,the quantitative values of 1,3,and 5 points converted from the results of all evaluation indicators are put through superimposed analysis to make the evaluation process of visual quality more universal.Finally,taking Hongtian Village in Yong'an City of Fujian Province as an example,a database of related forest landscape visual resources is established to make the evaluation more comprehensive.The article explores how to comprehensively evaluate the visual quality of rural forest landscape from the theoretical and practical aspects and put forwards the strategy of forest landscape visual resource management.The specific conclusions of this study are as follows:(1)Taking the connotation of rural forest landscape as a starting point,this article studies the theory and method of technical means of the rural forest landscape visual quality evaluation.It also determines the evaluation unit and establishes the comprehensive theoretical framework and evaluation process of the combination of the present situation of quality evaluation,visual acuity and visual absorption,so as to form a complete evaluation system.(2)In this study,the evaluation index system and method of the visual quality for rural forest landscape are proposed.The quality evaluation of landscape visual status is added to the evaluation system,trying to extend the landscape visual quality evaluation from a purely aesthetic perspective to an ecological perspective.Firstly,six evaluation factors of the current situation of landscape quality of rural forest landscape are determined,which are forest structure,tree species composition structure,phenology,stand origin,age group and canopy coverage.Secondly,four evaluation indexes of relative slope,visual probability,viewing distance and eye-catching degree are selected to evaluate the visual sensitivity of Hongtian Village.Thirdly,according to the characteristics of the study area,four factors including slope,slope direction,relief degree and vegetation richness are selected as the evaluation indexes of visual absorption.Fourthly,according to the hierarchy and the concept of various indexes,provide them with a suitable indicator description and give them appropriate standard values.Fifthly,apply GIS to create landscape resources database with its space analysis and evaluation function,to grasp the level distribution of the landscape quality assessment,visual acuity and visual absorption capacity in the study area,so as to provide the basis for resource management decisions.(3)Based on the comprehensive evaluation results of the visual quality of rural forest landscapes,the corresponding management objectives and suitability for future development of forest landscape visual quality areas with different levels are discussed.At the same time,according to the landscape status of Hongtian Village,specific countermeasures are given.To sum up,this study provides a basis for the construction and optimization of forest visual landscape in Hongtian Village of Fujian Province,and also provides a reference for the construction of rural forest visual landscape in other areas,which has important theoretical value and practical significance for further promotion of the construction of beautiful countryside.
