【摘要】：气候变化对以自然资源为生计基础的农业人口的影响尤为显著。明确农户对气候变化的适应需求,对于制定有效的气候变化适应政策、增强农户的气候变化适应能力非常重要。基于500份农户调查问卷,分析了甘南高原不同区域和不同生计方式农户对气候变化的适应需求,并利用二元logistic回归模型分析了影响农户适应需求的关键因素。结果表明:(1)在适应气候变化过程中,甘南高原农户对基础设施的需求最强烈,对信息和生产技术的需求次之;(2)不同区域农户对气候变化的适应需求存在差异。其中,纯牧区农户和农区农户对基础设施的需求均最强烈,半农半牧区农户对信息的需求最强烈;(3)不同生计方式农户对气候变化的适应需求也存在差异。其中,纯农户对信贷保险的需求最强烈,一兼户和二兼户均对基础设施的需求最强烈;(4)自然资本和物质资本是影响农户对生产技术需求的关键因素,自然资本和人力资本是影响农户对信息需求的关键因素,人力资本和金融资本是影响农户对基础设施需求的关键因素,自然资本、人力资本、金融资本、物质资本和社会资本均是影响农户对信贷保险需求的关键因素。提出了提升农户适应气候变化能力的政策建议。
[Abstract]:The impact of climate change on the agricultural population based on natural resources is particularly significant. Defining the adaptation needs of farmers to climate change is important for the formulation of effective climate change adaptation policies. It is very important to enhance the adaptability of farmers to climate change. Based on 500 peasant household questionnaires, this paper analyzes the adaptation needs of farmers in different regions and different livelihood ways in Gannan Plateau. The key factors affecting farmers' adaptation demand are analyzed by using the binary logistic regression model. The results show that the farmers in Gannan Plateau have the strongest demand for infrastructure in the process of adapting to climate change. The demand for information and production technology is the second. (2) there are differences in the adaptation needs of farmers to climate change in different regions, among which, the demand for infrastructure is the strongest among farmers in pure pastoral areas and farmers in agricultural areas. Rural households in semi-agricultural and semi-pastoral areas have the strongest demand for information. (3) there are also differences in the adaptation needs of farmers to climate change in different livelihood ways. Among them, the demand for credit insurance is the strongest among pure farmers. (4) Natural capital and physical capital are the key factors influencing farmers' demand for production technology, and natural capital and human capital are the key factors influencing farmers' demand for information. Human capital and financial capital are the key factors that affect farmers' demand for infrastructure, natural capital, human capital and financial capital, Both physical capital and social capital are the key factors influencing farmers' demand for credit insurance, and some policy suggestions are put forward to improve farmers' ability to adapt to climate change.
