不同石漠化等级地区农村薪柴消费的影响因素

Consumption Influential Factors of Firewood Energy in Karst Rural Area with Different Rocky Desertification Levels

为不同石漠化等级喀斯特农村区域能源发展、生态文明建设及乡村振兴发展提供科学依据和决策参考,选择代表中国南方喀斯特环境总体结构的3个示范区为研究对象,基于432份农户层面的调查数据,采用Tobit模型对不同石漠化等级研究区薪柴消费的影响因素进行回归分析。结果表明:潜在-轻度石漠化地区的薪柴消费主要受经济特征的影响,薪柴消费量与年均收入、能源支出占比呈显著负相关,与耕地面积呈显著正相关;中-强度石漠化地区的薪柴消费主要受家庭特征的影响,薪柴消费量与人口数量、户主年龄呈显著正相关,与外出打工人数呈显著负相关,与海拔呈显著正相关;无-潜在石漠化地区的薪柴消费量与林地面积呈显著正相关,与养殖数量呈显著负相关。针对不同石漠化等级研究区,提出相应的能源结构优化建议。

To provide the scientific basis and decision-making reference for energy development,ecological civilization construction and rural revitalization development in karst rural areas with different levels of rocky desertification,three demonstration areas representing the overall structure of karst environment in South China were selected as the research objects.Tobit model was adopted to conduct regression analysis on the influencing factors of firewood consumption in the study area with different rocky desertification levels based on 432 survey data at the peasant household level.Results:The consumption of firewood in the potential-slight rocky desertification areas was mainly affected by the economic characteristics and firewood consumption was negatively and significantly correlated with annual income and energy expenditure,and positively and significantly correlated with cultivated land,and firewood consumption in medium-intensity rocky desertification areas was mainly affected by family characteristics,firewood consumption was significantly and positively correlated with population size and household head age,negatively and significantly correlated with the number of migrant workers,and positively and significantly correlated with altitude.The consumption of firewood in non-potential rocky desertification areas was significantly and positively correlated with forest land area and negatively and significantly correlated with the amount of aquaculture.In view of different rocky desertification grade research area,the corresponding energy structure optimization suggestions were put forward.
