南京设施蔬菜生产系统的可持续性研究——基于经济和社会管理层面

随着我国设施蔬菜产业的迅速发展,设施农业生产系统的经济和社会可持续发展成为人们关注的焦点。本文以南京市典型设施蔬菜生产系统为例,围绕设施蔬菜生产的经济收益和社会管理方式,在设施蔬菜生产者和管理层问卷调研的基础上,构建相应评价指标体系,研究了设施蔬菜生产的经济和社会管理现状。结果表明,设施蔬菜生产的经济收益尚可,但多数蔬菜产量呈逐年下降趋势,其收益较难满足生产者较重的经济负担,缺乏相关政府补贴政策;生产基地的社会管理手段有限且缺乏力度,如农用物资未实现统一化管理,蔬菜质量控制手段有限,缺乏有效农业技术推广服务。最后,针对设施蔬菜系统的经济与社会管理现状,提出了一些促进系统可持续发展的建议。

Sustainability of Greenhouse Vegetable Production System in Nanjing: An Assessment Based on Economic and Social Management Dimensions

Concerns are growing about economic and socio-institutional sustainability of greenhouse vegetable production (GVP) in China with its rapid development. The economic and socio-institutional aspects were assessed in greenhouse vegetable production system in Nanjing based on a household survey and their established indicators. The results revealed a decrease trend of yield for most of vegetables, a lower income for vegetable producers in view of their heavy economic burden and few subsidies from the government. As for socio- institutional aspects, ineffective agricultural input management, limited control of the greenhouse vegetable quality and low efficiency of the agricultural extension services were also found. Finally, some recommendations were also outlined for the promotion of sustainable GVP.
