中文摘要：

随着我国食品安全、环境压力、三农问题、绿色贸易壁垒等问题的加剧,有机农业作为一种可持续的新型农业发展模式,为以上问题的解决提供了新的范式.有机农业认证作为连接有机农业生产者与消费者的纽带,是有机农业生产链的核心构成之一.有机农业认证体系是我国有机农业生产网络中信息网络的重要组成部分,有机农业认证机构作为信息网络的核心构成,对认识我国有机农业信息网络的结构与组织有着积极的作用.本文基于对有机认证机构为代表的信息中心的空间分布、组织与影响腹地范围分析,认为我国目前有机农业信息中心空间分布呈较强的不均衡性特征,且发育程度具有一定的等级层次性.采用层次分析法进一步对中国有机农业认证信息中心的影响度进行评析,分析表明我国有机认证信息中心分为三大综合等级.此外,选取以北京、浙江和辽宁为代表的重点地域空间进行探讨,并针对不同等级的有机农业认证信息中心提出相应的发展策略和建议.

英文摘要：

With the pressure on China＇s environmental protection, food security,rural issues, green trade barriers. Organic agriculture as a kind of newtype of alternative agriculture production model can coordinate the conflictsand solve the problems. Organic certification system, connecting organic farmersand consumer, is an important part of organic agricultural production network.Organic certification agencies which are the core of information networkhave a positive effect on learning about the structure, organization and influence of this network. This paper, based on the analysis of the spatialdistribution, organization and influential area of the organic certificationinformation centers in China, suggests that the spatial distribution of thesecenters are characterized by disproportion, and the degree of developmentlevel of these centers have large differences. The analysis of these centers’influence shows that they can be divided into three comprehensive grades. Inaddition, this paper focuses on some core areas such as Beijing, Zhejiang andLiaoning. Based on above analysis, the author put forward some suggestions forfurther development of these organic information centers.
