Organic agriculture is an ecological production management system that promotes and enhances biodiversity, biological cycles, and soil biological activity. It is based on the minimal use of off-farm inputs and management practices that restore, maintain, and enhance ecological harmony. The benefits of organic farming include reducing chemical input and loss of land, enhancing food security, rural development, sustainable livelihoods, and environmental integrity. Organic food is produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations. Organic meat, poultry, eggs, and dairy products come from animals that are given no antibiotics or growth hormones. Organic food is produced without using most conventional pesticides, fertilizers made with synthetic ingredients or sewage sludge, bioengineering, or ionizing radiation. The development of organic food production bases is the effective measure to protect eco-environment, reduce agricultural non-point source pollution, recover agroecosystem health, and is the important way to ensure food security. However, with the development of the organic food production bases, there is a pressing need for a supervision system in environmental protection department. The application's method and technique process for the supervision of organic food production bases in China are currently expected to be established and perfecedt further. It is significant to establish the method and technique process for the supervision of organic food production bases. This paper researches the method for monitoring the eco-environment in organic food production bases and its buffer areaa based on high-resolution remote sensing data, and introduces the model and method for evaluating the risks facing organic food production bases. Firstly, according to The National Organic Food Standards and appraisal management provisions for organic food production bases, the objectives to be supervised in organic food production bases are different from those in its buffer areas. So, the classification system for organic food production bases was established to describe the spatial pattern of organic food production bases and its buffer areas. Significantly, the classification in organic food production bases is different from its buffer areas. Secondly, the monitoring index system which was derived from the classification data was established to achieve a deeper level of assessment on the condition and the risk source of the organic food production bases. Then, in order to determine the level of risk, the model and method for risk assessment of organic food production bases was established. The organic food production bases risk index (OFBRI) was calculated based on the main monitoring index. Five-level risk assessment was used to differentiate risk degree, and the evaluation criteria of risk levels are introduced. Finally, the technique process is applied to monitor the eco-environment and risks source of one of organic food production base in Jilin province. After the actual application, this method has been proven with satisfactory results on technical features and functional obtained. It can enlarge the range of application of this method to various organic food production bases. The method and technique process for supervision of organic food production bases can provide technical support for check and review the requirement of organic food production bases. ©, 2014, Chinese Society of Agricultural Engineering.
