摘要
The base of non-pollution agricultural products is a prerequisite for the non-pollution agricultural production. Based on two factors, i.e., irrigation water and soil, the environmental quality of Yilan county＇s base of non-pollution agricultural products was evaluated by single pollution index. The main monitoring items included the content of Hg, Se, Cr, Pb, fluoride, and so on, and the evaluating results showed Pi〈1 which indicated that this area was fit for developing not only non-pollution products but also greenfood of A level.
