| 摘 要： | 农业生态系统的可持续发展是实现中国可持续发展战略的基本保证和前提条件。限制因素的识别是评价农业生态系统可持续性、制订农业可持续发展战略及实施综合措施的关键步骤。以南京市江浦县为例,分析了农业生态系统可持续发展的主要限制因素及其调控对策。研究表明,耕地资源持续减少、生态灾害频繁发生、系统抗干扰能力不强等是该区农业生态系统可持续发展的主要限制因素;在此基础上,提出了“保护耕地资源、增强系统抗性、控制生态灾害”的对策建议,以促进江浦县农业生态系统的可持续发展。

| Abstract: | Sustainable agricultural ecosystem are the basic guarantee and condition for the sustainable development of society and economy. The identification of limiting factors is a crucial step to assess the sustainability, to work out the strategies and to implement comprehensive measures for sustainable development of agricultural ecosystem. As a case study, the limiting factors and regulation strategies for the sustainable agricultural ecosystem in Jiangpu county, Nanjing city are analyzed. The results show that the main limiting factors are the decreasing trend of arable land, frequent occurrence of ecological disasters and the weak ability against external perturbation of agricultural ecosystem. The countermeasures for promoting the sustainable development of agricultural ecosystem in Jiangpu county, Nanjing city, including the protection of arable land, the enhancement of the ability against external perturbation, and the control of ecological disasters are suggested. |
