Abstract: This paper selects agricultural chemicals and economic data of six provinces and one city in East China from 2001-2014 and analyzes Tapio decoupling relationship between agricultural chemistry and agricultural economic growth in the context of agricultural non-point source pollution control. The paper decomposes the factors of the agriculture chemical input with LMDI decomposition and then clusters agricultural chemical efficiency of provinces in East China by K-means. The results show that with the growth of agricultural output, the agrochemical inputs amount of six provinces and one city in East China showed a trend of “first increase and then decrease” during 2001-2014. Under the background of agricultural non-point source pollution control, the relationship between agricultural chemistry and agricultural economic growth presents absolute decoupling relationship. Agricultural economic growth and environmental resource protection can be developed coordinately, and the agricultural non-point source pollution control policy can be sustainably implemented based on the adjustment of agricultural chemical participation. The increase of agricultural chemical inputs is mainly caused by the land effect. The efficiency effect can slow down the growth of agricultural chemical inputs. The increase of agricultural output value of per unit, which depends on the agricultural chemicals production, is the driving force of the rapid increase of agricultural chemical inputs, and the progress of science and technology of agricultural chemicals production can reduce the amount of agricultural chemical inputs and ensure agricultural output value per unit area. There is great spatial difference in the dependence of the agricultural economy growth on agricultural chemicals. The dependence of agricultural economy growth on agricultural chemical is higher in Anhui Province. In short, agricultural economic can grow sustainably if agricultural non-point source pollution is controlled. To control agricultural chemicals, we need to improve the utilization rate of agricultural chemistry, use a variety of agricultural efficiency means and take the regional differences in consideration.

Key words: agricultural chemical, decoupling index, LMDI model, six provinces and one city in East China
