Evaluation Of The Aesthetic Quality Of Terraced Landscape And Research On Improvement Path In Southeast Guizhou

Guizhou is the only province in China without plain support,the terraces distribution have a large scale and wide area in southeast Guizhou,and the terraces is becoming an important landscape resource relying on the development of agricultural tourism in the villages of southeast Guizhou to realize rural revitalization.With the accelerated development of urbanization,the phenomena of "non-agriculturalization and non-grain orientation" in the rural areas of the mountainous areas of Southeast Guizhou Province under the background of rural-urban migration continue to be highlighted,and the sustainable issues such as the deterioration of the aesthetic quality of terraced landscapes and the weakening of landscape versatility are becoming increasingly serious.Therefore,it is urgent to conduct a study on the evaluation of the aesthetic quality of terraced landscapes in Southeast Guizhou Province,to clarify their multi-functional value,and to propose a strategy to improve the aesthetic quality of the landscape from multiple perspectives.In order to provide scientific reference and theoretical basis for the sustainable protection and development of the terraced rice field landscape in southeast Guizhou,and to realize agricultural tourism to promote rural revitalization in the mountainous areas of Guizhou.This paper analyzes the aesthetic quality of the terraced landscape in the Qingshui River Valley of southeast Guizhou,through several field visits to the current situation of the terraced landscape utilization in the River Valley of southeast Guizhou,and analyzes the aesthetic quality of the terraced landscape in the Research area by using GIS spatial analysis,questionnaire survey method,BIB-LCJ aesthetic judgment method and econometrics,clarifies the current situation of terraced landscape distribution and terraced types in the region,reveals the aesthetic attitude of potential tourists towards the terraced landscape,and explores the influence of The factors affecting the aesthetic quality of the terraced landscape in the River valley are discussed,and countermeasures for the protection and utilization of the terraced landscape in the study area and the improvement of the aesthetic quality are proposed.According to the framework of the thesis,the research focuses on the following four aspects.(1)Summarize landscape pattern and characteristics.Terraced fields are the dominant landscape type in the River Valley region,mainly concentrated on the medium topographic gradient level,and show certain fragmentation characteristics,the landscape level and village level on the terraced landscape is weak in dispersion and strong in aggregation.(2)Analysis of the attitude of potential visitors to the terraced landscapes.Evaluators have a positive attitude towards the terraced landscape of the Qingshui River Valley,with an average beauty degree of 2.775 and a high overall aesthetic quality of the terraced landscape;from the terraced type,the evaluators rank the aesthetic quality of the terraced landscape in the study area from high to low as terraced,village field type,forest field type,mixed type,and their preference for different The preference of terraced landscape in different seasons from high to low is growth period,irrigation period,maturity period;based on the evaluation results.(3)Clarify the influencing factors of landscape aesthetic quality.The ordered Probit regression model results show that "type of residence(0.009)" at the level of individual endowment and "type of terraces(0.075),viewing weather(0.003),and whether the terraces are abandoned(0.006)" at the level of landscape are significantly correlated with the terraces landscape aesthetic quality rank.Among the independent variables,landscape characteristics are the main factors affecting the aesthetic quality of terraced landscape,among which,viewing weather and whether the terraced fields are abandoned are the main characteristics affecting the aesthetic quality of landscape;the contribution of significance factor from high to low is "viewing weather,whether the terraced fields are abandoned,viewing period,landscape type".(4)Propose the strategy of terrace landscape quality improvement.To improve the aesthetic quality of terraced landscape in Qingshui River Valley,it is urgent to pay attention to the protection of terraced regional landscape,and formulate corresponding policies to promote the rational protection and development of landscape resources of terraced system from the aspects of reducing the scale of terraced wasteland,increasing the utilization rate of terraced landscape,maintaining the systematization and integrity of terraced landscape pattern,and preventing or reducing "hollowing out and non-grain",so as to achieve high added value of terraced landscape.
