Abstract: The relationship between economic growth indicator and non-point source(NPS) pollution,inclusive of agricultural fertilizer,farming film and pesticide amounts per unit sown area,was researched using software Eviews 6.0 by econometric analysis method. The obtained relationship was verified by the Environmental Kuznets Curve(EKC) model. The time series data of Chongqing from 1996 to 2011 were selected as an illustration example. Results show that the curve of economic growth vs. the amount of fertilizer,farming film and pesticide per unit sown area has an apparent reverse U-shape,with 2009 as the turning point,displaying EKC features. Moreover,the fitting result by using per capita agricultural output value as the agricultural economic growth indicator is better than that using per capita planting industry output value. This research reveals that in less developed Karst mountainous area,the economic growth pattern should be transformed into scientific development. Ecological and recycling agriculture should be enhanced to reduce the amount of agricultural fertilizer,farming film and pesticide.
Key words: agricultural NPS pollution, agricultural economic growth, Environmental Kuznets Curve, adjustment of industrial structure
