【Abstract】 The production of organic vegetables plays an important role in the agricultural structural adjustment and it also contributes to the income of farmers. When formulating the project for organic vegetable bases, such factors as soil,air and water conditions should be fully considered to make sure that the products are safe. Besides, the locations of the bases should be far away from those factories causing serious pollution and should keep a certain distance from highways.
