干热河谷地区农户生计策略价值对生计资本的响应
Response of Households'Livelihood Strategy Value to Livelihood Capital in Dry-hot Valley Areas
摘要
Abstract
Dry-hot valley areas are characterized by aridity and lack of rain.The fragile ecological environment of such re-gions poses huge challenges to the sustainability of the livelihood of local farmers,and the diversification strategies adopted by farmers are strongly related both to the quality of their livelihood and to sustainable regional development.This study an-alyzed the responses to a questionnaire returned by 629 farmers in Yuanmou County,which is in the dry-hot valley of the Jinsha River(China).First,the livelihood strategy value(VLS)index was proposed by integrating the richness,homoge-neity,and profitability of livelihood strategies.Second,the livelihood capital index system applicable to Yuanmou County was constructed and evaluated.Using livelihood capital as the independent variable,ordered logistic regression and random forest contribution ranking methods were used to identify the key elements of the livelihood capital affecting the VLS of the farmers,and to explore the response of the VLS to livelihood capital.The results reveal the following.(1)The average VLS of the farmers is 17.09,and farmers with a medium VLS account for the majority of samples.(2)The VLS of farmers is re-gionally differentiated,with areas of high VLS concentrated mainly in regions with relatively flat terrain and close to the county town.(3)The size of the labor force,the education level of the labor force,and the annual household income have substantial positive impact on the VLS.Therefore,it is suggested that the education and vocational/technical training of farmers be strengthened to improve the skill and literacy of the labor force.Moreover,the government should provide con-venient financial services for farmers to support them in diversifying their activities and achieving a sustainable livelihood.关键词
