Study On The Landscape Gene Map Of Linpan In Chengdu Plain

Linpan is a rural settlement on the western Sichuan plain with "houses,forests,fields,and water" as the main elements.This paper takes the linpan within the range of Dujiangyan’s elite irrigation area as the research object,introduces the concept of biological genes,and proposes a study of landscape gene map based on tourists’ perception.This provides a new perspective for the rational protection,redevelopment and utilization of linpan in western Sichuan.This article is based on the theory of landscape gene map,through a field study of the law on linpan the natural environment,social environment,human parsing,layout,forms and other landscape features.On this basis,combined with object-oriented landscape characteristics of deconstruction method,identification plate of the Landscape genes of linpan.On the basis of feature analysis and landscape gene identification,combined with the tourist perception survey,the analytic hierarchy process is used to quantitatively analyze the importance of each landscape gene to extract the main genes and attachment genes of linpan.Furthermore,through the way of graphic expression,the landscape gene map of the forest disk in Dujiangyan Essence Irrigation Area was constructed.Taking the Zhangjiayuanzi linpan as an example,the related application of landscape gene map was proposed.Studies have shown that main of the plane of essence in Dujiangyan Irrigation District landscape genes for the water system,the overall pattern layout,roads,and the attachment genes are the overall Fengshui layout,courtyard,field,construction type,and patio.The main genes of the facade landscape are trees and windows,and the attachment genes are roofs,gables and ridge decorations.The main genes of the landscape perception are folk activities and cultural totems,and the attachment genes are architectural crafts.Various types of gene order of permutations and combinations,elevation map of forming a flat map of the forest,and sensory map.Through threedimensional atlas of the cross and integration,and formed comprehensive landscape gene map of linpan in the essence of Dujiangyan irrigation district.This paper comprehensively uses the landscape gene method to realize the quantitative description of linpan landscape genes,and constructs the landscape gene map of linpan.It is of great significance for a profound understanding of the settlement landscape elements in the western Sichuan Plain,the implementation of the protection and development of linpan,the inheritance of regional traditional culture,and the improvement of the landscape gene map of southern China.
