Study On The Quality Evaluation Of Lipan Rural Landscape In Western Sichuan

With the acceleration of Chengdu's urbanization and the continuous expansion of the city,the survival of rural landscape is facing great challenges.As a unique rural landscape pattern in the western Sichuan plain,the west Sichuan Lin pan has also witnessed the phenomenon of dilapidation and hollowness,facing the disappearing crisis.Based on the analysis of the literatures of the previous rural landscape evaluation and the field survey,this paper analyzes the landscape characteristics of west Sichuan Lin pan and selects the indicators of landscape evaluation.Using the method of expert consultation selection determines the western Sichuan Lin Pan evaluation index,and established the western Sichuan Lin pan landscape quality evaluation system,according to analytic hierarchy process(AHP)to determine the index weights of evaluation factors,finally the authors made an evaluation of the different types of Lin Pan and taking planning protection Suggestions are put forward.The main research results are as follows:The evaluation system of landscape quality of west Sichuan forest was established by expert consultation and analytic hierarchy process(AHP),and the criterion layer was 3 and 17 factors of the index layer were established.Rule layer as the aesthetic value,ecological value and social value,aesthetic value selection includes residential local characteristics,health status,overall coordination,the seasonal change,water quality,visual and psychological feeling as index layer,select the plant ecological value configuration mode,vegetation diversity,green coverage rate and maintain the function of the carbon and oxygen balance,purifying function,degree of landscape fragmentation,landscape diversity as index layer,the social value of external traffic convenience,clear on the internal transport,sustainable development culture and shu culture heritage as index layer.By means of the combination of analytic hierarchy process and questionnaire,the judgment matrix is constructed and the weight of the index is calculated.The results show that the ecological value(0.466)> aesthetic value(0.275)> social value(0.259).The most important factor in ecological value is the purification function,the most important factor in aesthetic value is the local characteristic of the folk house,and themost important factor in the social value is Bashu culture.According to build the evaluation index system,the fuzzy comprehensive evaluation method to evaluate the western Sichuan Lin Pan different types of Lin Pan rural landscape,farming Lin Pan overall quality is good,special industry Lin Pan is better or general,special industrial type of nursery flowers Lin Pan overall quality is good,the animal husbandry Lin Pan overall quality for the general characteristic industry,rural tourism Lin Pan overall quality is good,the ecotype Lin Pan overall quality is general,according to the different Lin Pan rural landscape quality value,put forward the corresponding rationalization proposal of protection and development,provide reasonable reference for the rural landscape of research in the future.
