基于生态位理论的重庆市乡村发展格局特征分析

Characteristics of rural development pattern in Chongqing based on niche theory

乡村振兴是乡村地域系统的整体发展,因此,识别乡村各个子系统的发展态势具有十分重要的意义。文章基于生态位理论揭示乡村经济、社会、粮食生产、农业生态环境现状。结果表明:重庆市农业生态环境和经济生态位宽度指数较宽,社会和粮食生态位宽度偏窄,综合生态位宽度各区县差异不显著,对比经济-社会-粮食-农业生态环境综合生态位宽度和经济-社会-粮食综合生态位宽度,区位条件、资源禀赋、农业生态环境制约乡村高质量发展。

Rural revitalization is the overall development of rural regional system.Based on niche theory,it reveals the current situation of rural economy,society,grain production and ecological environment.The results show that the agricultural ecological environment and economic niche breadth index are wide,the social and grain niche breadth is narrow,and the difference of comprehensive niche breadth among districts and counties is not significant.Compared with the economic-social-grain-ecological comprehensive niche breadth and the economic-social-grain comprehensive niche breadth,the ecological environment restricts the high-quality development of rural areas.
