This study was performed in the intensive agricultural region in the coastal area of southeast Lake Dianchi, Yunnan province, China. (1) Most farmers cultivated six or seven crops per year. This very high cropping intensity is based on the combination of vegetables with a short growing duration and transplanting culture. However, the amount of applied nutrient exceeds crops demand in many intensive cropping fields. (2) The concentrations of N, P, and K in soil increase to a larger extent with input of N, P, and K from chemical fertilizers than from manure. Reducing the input of N, P, and K would be more efficient than increasing their output for restoration of the environmental impact. (3) In constructed wetland, harvest of reed affects the aboveground regrowth and nitrification and denitrification activity of the root mat.

本研究是在中国云南省滇池东南部沿海的集约化农业区进行的。(1)大多数农民每年种植六到七种作物。这种非常高的种植密度是基于种植期短的蔬菜和移栽栽培的结合。然而，在许多集约化种植领域，施用的养分量超过了作物的需求。(2)土壤中N、P、K含量随化肥施用量的增加而增加的幅度大于随有机肥施用量的增加。减少氮、磷、钾的投入比增加其产出更能有效地恢复环境影响。(3)人工湿地中，芦苇的收割影响了地上部分的再生和根垫的硝化反硝化活性。
