重庆市乡村生产空间系统风险评价及其空间分异格局

Risk assessment and spatial differentiation pattern of rural production space system in Chongqing Municipality

科学评价乡村生产空间系统风险水平并揭示其空间格局特征,差异化设计风险管控措施,对引导和调控乡村生产空间系统多元主体行为选择、实施健康可持续乡村振兴战略具有重要意义。在理清乡村生产空间系统风险机理的基础上,从风险源压力、风险载体状态、风险控制机制响应三个方面构建了乡村生产空间系统风险综合评价指标体系,以重庆市37个区县为研究单元,2016年为研究时点,评价了乡村生产空间系统风险水平并揭示其空间分异特征,据此提出了乡村生产空间系统风险管控的差异化措施。研究表明:(1)乡村生产空间系统风险的产生是风险源压力、风险载体状态、风险控制机制响应三者相互联系、共同作用的结果。(2)重庆市乡村生产空间系统风险总体上属于中等水平,呈现出"东高西低"的空间格局,系统压力、状态、响应水平空间分异特征明显,并从空间管制、土地利用模式、防灾减灾救灾体系等维度提出了差异化风险管控措施。

It is of great significance to scientifically evaluate the risk level of rural production space system, reveal the characteristics of its spatial pattern, and design risk control measures differently, so as to guide and regulate the multi-subject behavior choice in rural production space system and implement healthy and sustainable rural revitalization strategy. Based on sorting out the risk mechanism of rural production space system, this paper constructs a comprehensive risk evaluation index system of rural production space system from three aspects: the pressure of risk source, the status of risk carrier, and the response of risk control mechanism. Taking 37 districts in Chongqing Municipality as the research unit, and the year 2016 as the time point for the research, this paper evaluates the risk level of the rural production space system and reveals its space differentiation characteristics. On the basis of risk control, we identify the differentiation of rural production space system. The results show that:(1) The generation of risk in rural production space system is the result of interrelation and joint action of risk source pressure, risk carrier status and risk control mechanism response.(2) The risk of rural production space system in Chongqing is generally at a medium level,showing a spatial pattern of "high in the east and low in the west". There are obvious spatial differentiation features of system pressure, status and response level. Finally, differentiated risk control measures are proposed on the dimensions of space control, land use pattern and disaster prevention, reduction and relief system.
