农业生态安全及其生态管理对策探讨

Discussion on the agricultural ecological security and its management countermeasures.

对生态安全和农业生态安全的基本内涵进行了探讨。认为生态安全是指不同尺度的生态系统及其生物要素、环境要素、资源要素等在数量、质量及其相互作用关系上的一种和谐、健康、稳定的状态和水平。农业生态安全包括农业环境安全、农业资源安全、农业生物安全和农业产品安全等几个方面的内容。提出了一系列农业生态安全管理对策 ,包括 :①加强农业生态安全管理 ,发展生态产业 ;②加强对现有资源与生态系统的保护、培育与可持续利用 ;③保护农业生物多样性 ,保障生物安全 ;④加强农业综合抗灾能力建设 ;⑤加强农业生态安全监测与法律法规体系建设 ;⑥建立良好的、和谐的社会、经济和政治关系。

The basic concepts and contents of ecological security and agroecological security were discussed in this paper.Ecological security could be defined as a dynamic state or degree of harmony,health and stability in quantity,quality and relationships for different scales of ecosystems including biological,environmental and resource factors.Agroecological security consists of agricultural environmental security,resource security,biological security and food security.A series of management countermeasures for agroecological security were put forward,such as to strengthen agroecological management,to develop eco-industries,to reasonably protect and exploit natural resources,ecosystems and biodiversity,to improve hazard-defense systems and to establish monitoring systems,laws and regulations for agroecological security.
