According to Food Safety Law of the People's Republic of China implemented on June 1, 2009, the whole-process control of food safety "from farmland to dining table" is carried out. The so-called "farmland" means agricultural production base environment. Thus it can be seen that the quality of the base environment is an important factor to ensure the safety of agricultural products. Among various certification activities specific to food carried out by our country, the certification of agricultural production base environment is indispensable.
