乡村空间重构中农户行为与生态环境的响应研究——以宁夏永宁县为例

Study on the response mechanism of farm household behavior and ecological environment in rural spatial reconstruction--Based on the case of Yongning County in Ningxia

乡村空间重构中人地关系脉络、响应机理探究是乡村振兴与建设亟待解决的问题.以我国乡村重构试点永宁县为例,采用入户调查结合Landsat TM影像生态解译,构建DPSIR指标体系,以多元有序Logistic模型揭示乡村空间重构中农户行为与生态环境的关系及响应机理.研究结果表明,近10年乡村空间重构中农户生活空间向集中化、生产空间向规模化、生态空间向人地共生演变.土地流转是乡村生态环境变化的主要驱动力,就业渠道是压力源,教育和基本公共服务难以满足需求是基本状态,农户对生态环境的主体意识和责任认知影响了生态功能提升.基于此,从人和地两方面提出优化调控人地关系的机制,以形成乡村人与生态的良性循环,为人与自然共同体、乡村建设的政策制定提供借鉴.

To reveal the relationship and response mechanism between human and land are the urgent problems for the revitalization and construction of rural areas in the reconstruction of rural space.The DPSIR evaluation index system is established for revealing the response mechanism between farmer's behavior and ecological environment.Based on 1347 questionnaires and Landsat TM image interpretation of Yongning County in Ningxia,it is found that the trend of households living space centralization,production space scale,and ecological space to human land symbiosis has evolved in rural spatial reconstruction in recent 10 years.The farm households land transfer behavior is the main driving force of rural ecological environment change,employment channel is the source of pressure,and basic public services such as education and transportation cannot meet the demand is the basic state.Moreover,farm households subjective consciousness and responsibility cognition of ecological environment affect the level of ecological function.Therefore,we should optimize and regulate the relationship human and land in order to form a higher productivity and virtuous cycle of rural ecosystem.It can provide scientific basis and reference for the community of man and nature,rural construction and high quality development policy making.
