Sustainable Development Evaluation Of Terrace Landscape In Longji,Guangxi

Longji terrace,located in Longji Town,Longsheng Autonomous County,Guangxi Zhuang Autonomous Region,is an important part of the global agricultural cultural heritage of rice terrace system in southern China.As a result of terraced cultivation,terraced landscape is a cultural landscape with special value and special landform.Longji terraces have unique terraces landscape: terraces are distributed in series,terraces are multi-level,and folk culture landscape is rich,attracting a lot of external tourists and increasing communication with the outside world.Since 1980,Longji terrace has gradually developed tourism,creating new employment opportunities for the villagers,and the villagers have got rid of the poverty-stricken living condition that can only meet the basic needs of food and clothing.However,after the investigation of Longji terraces,it is found that with the development of tourism,the communication between Longji terraces and the outside world has increased,the local culture has been impacted,and the way of village livelihood has changed.Because the income of tourism is several times higher than that of agriculture,villagers are more willing to engage in tourism than agriculture.The resulting phenomenon is that a large number of agricultural labor force(especially young labor force)transferred to the tourism industry,and a large area of terraces was abandoned.In the long run,the labor resources of agriculture are more and more scarce,the waste area of terraces is increasing,the terraced landscape is threatened,and the sustainable development of the terraced landscape of Longji is questioned.Therefore,this paper takes the terrace landscape of Longji as the research object and sustainable development as the research content to explore the sustainable development degree of the terrace landscape of Longji.In fact,terrace landscape is a landscape integrated with four elements of mountain forest stream terrace village.Under the framework of supporting the development of the whole landscape system,we need to build a sustainable development index system of terrace landscape from four dimensions of mountain forest,stream,terrace and village,and we must choose a comprehensive evaluation method.In this paper,the author chooses entropy weight method and fuzzy comprehensive evaluation method to get the comprehensive evaluation of the sustainable development of the terrace landscape in Longji,and then uses the development obstacle model to calculate the obstacles of each index to the sustainable development of the terrace landscape.The results show that: in the period of undeveloped tourism,Longji area is still in the traditional agricultural economic period,and the agricultural income is the main income of the family.Each household needs to maintain the terraced agriculture carefully.Therefore,in this period,the management and maintenance of the terraced fields are meticulous.Agriculture is the livelihood of the whole family,and the sustainable development ability of the terraced landscape is very good.In the early stage of tourism development,the number of tourists is small,and the number of tourists is very small The proportion of tourism income to family income is not high,and agricultural income is still the main source of livelihood for families.At this time,each household's management and maintenance of terraces is still thoughtful and meticulous,and the sustainable development ability of terraced landscape is good.In the middle stage of tourism development,the number of tourists increases every year,and tourism income has become the main income of families.Agricultural income is no longer the main source of income for families.Family agriculture The industrial labor force gradually turns to the labor force of tourism service,and the sustainable development degree of terrace landscape is weak;at the current stage of tourism development,the number of tourists and the source of tourists are stable and rising steadily,tourism income has become the key source of income for families,and the role of agricultural income in family income has been less than its micro level.During this period,the role of agriculture is limited to maintaining its rice terrace landscape,and the terrace landscape can The ability of sustainable development is very weak.Among them,the main obstacles to the sustainable development of terraced landscape at this stage are: the average number of labor force of tourism households,the average number of labor force of agriculture households,the average age of labor force of agriculture households,and the average age of labor force of tourism households.In order to solve this problem,the following suggestions are put forward: to build a new model of "share sharing" arable land;to declare the intangible cultural heritage of "terraced cultivation technology";to build a brand of Longji rice and to apply for green food certification.
