Studies on nitrogen, phosphorus and potassium nutrients cycles in the subsystems of farmland, hilly area and waterbody at Shanyi Village of Xiaoshan City in Zhejiang province were studied. The results indicated that the soil organic matter content in the village was relatively rich; the inorganic nitrogen fertilizer was overused; the total input of P fertilizer was far lower than that of total output, and the K input was also low. The waterbody has been eutrophicated and fish growth coefficient was only 2.96, much lower than the average value.
