摘要:

研究在解析乡村生产空间系统适应性内涵、构建其分析框架的基础上,从易损性、稳定性、响应三个维度构建乡村生产空间系统适应性评价指标体系,运用适应性评价模型评价重庆市江津区近11年乡村生产空间系统运行状态,辅以障碍度模型诊断并测算其适应性障碍因子和适应性障碍度,进而提出针对性策略以破解其所面临的现实困境,结果表明:2007—2017年江津区乡村生产空间系统适应性总体呈波动上升且不断增强趋势,系统可持续发展能力稳步提高;系统适应性障碍度由稳定性、响应障碍向易损性障碍转变,其关键障碍因子为化肥使用量、农膜使用量、乡村生产总耗能、城镇工矿用地面积、乡村环保投资额占比等;以发展生态农业、有机农业,强化环境保护为前提降低系统易损性,拓展富硒特色农业增值空间和有效增加乡村资金、人才与技术投入提升稳定性与响应能力是增强乡村生产空间系统适应能力的关键。

Abstract:

By analyzing the connotation of the adaptability of rural production space system, and constructing a framework of the adaptability, this research establishes an evaluation index system for the space system in the following three dimensions: the vulnerability, the stability, and the response. Then, taking Jiangjin district of Chongqing as an example and using the adaptive evaluation model, this paper evaluates the operation status of the rural production space system from 2007 to 2017. At the same time, the factors of the adaptability obstacle of rural production space system were diagnosed by using the obstacle degree analysis model, and the indexes of the adaptability of rural production space system and the adaptability obstacle degree of criterion layer were calculated. Based on the above research, by analyzing the factors that cause the obstacle to the adaptability of the rural production space system, this paper puts forward some targeted strategies to solve the current reality of the dilemma in the operation of the rural production space system in Jiangjin district of Chongqing. The results show the following aspects. From 2007 to 2017, there is a trend of rising and increasing volatility of the adaptability of rural production space system in the study area on the whole, which shows that the sustainable operation and development capacity of the rural production space system has been improved steadily. The degree of adaptability obstacle of rural production space system has gradually changed from stability obstacle and responsiveness obstacle to vulnerability obstacle, and the key obstacles of the adaptability of the system include the amount of fertilizer used, the amount of agricultural film used, the total energy consumption of rural production, the area of urban industrial and mining land, and the proportion of rural environmental protection investment. It is the key to enhance and improve the adaptability of rural production space system in the district, which aims, on the premise of developing ecological agriculture and organic agriculture and strengthening environmental protection, to reduce the vulnerability of the system, expand the value-added space of selenium-enriched agriculture, effectively increase rural investment in capital, talent and technology to strengthen the stability and response ability.
