摘要:
[目的] 探究喀斯特石漠化地区农户生计资本与生计策略的关系,甄别农户生计策略影响因子,为促进该地区农户生计策略最优选择提供理论依据。[方法] 基于可持续生计分析框架计算贵州省关岭贞丰花江石漠化综合示范区(简称花江示范区),农户生计资本,运用多元Logistic回归模型对不同农户生计策略进行分析,探究该地区农户生计资本与生计策略的关系。[结果] ①花江示范区农户人力资本指数最高,物质资本和自然资本指数较低。②示范区内农户以非农型生计策略为主,主要集中在查耳岩村和峡谷村。③人力资本是农户生计策略转化的最大影响因子,对于农兼型、兼农型和非农型农户的生计策略转换影响较大。④非农业收入和家庭劳动力人数的增多有助于促进农户选择更为多元的生计活动,耕地面积、退耕还林地面积及牲畜资本对于生计策略的转化为负向影响。[结论] 花江示范区内各行政村受自然条件限制,生计资本存量和生计策略选择存在一定差异,提升人力资本可以有效促进示范区内农户生计策略转型。

Abstract:
[Objective] The relationship between livelihood capital and livelihood strategies of farmers in karst rocky desertification areas was explored, and the impact factors of livelihood strategies was identified, in order to provide theoretical basis for promoting the optimal choice of livelihood strategies of farmers in the region.[Methods] Based on the framework of sustainable livelihood analysis, the livelihood capital of farmers in the Guanling-Zhenfeng Huajiang rocky desertification comprehensive demonstration zone of Guizhou Province was calculated. The multiple logistic regression model was used to analyze the livelihood strategies of different farmers to explore the relationship between the livelihood capital and livelihood strategies of farmers in the area.[Results] ① The human capital index of farmers in Huajiang demonstration zone was the highest, and the physical capital and natural capital indexes were lower. ② The farmers in the demonstration area were mainly non-agricultural livelihood strategies, mainly concentrated in Cha Eryan village and Xiagu village. ③ Human capital was the main influencing factor in the conversion of farmers' livelihood strategies, and it had a great impact on the conversion of livelihood strategies of both farming, part-farming and non-farming farmers. ④ The increase in non-agricultural income and the number of family laborers was conducive to promoting farmers to choose more diversified livelihood activities. The cultivated land area, the area of returning farmland to forest land, and livestock capital had a negative impact on the conversion of livelihood strategies.[Conclusion] The administrative villages in the Huajiang demonstration zone are limited by natural conditions, and there are some differences in the livelihood capital stock and the choice of livelihood strategies. The improvement of human capital can effectively promote the transformation of farmers' livelihood strategies in the demonstration zone.
