文章采用宏观和微观相结合的研究方法，从省域、流域、县域、乡域等不同尺度来研究江苏太湖地区氮肥施用与产量、氮肥利用率及氮肥环境损失的关系，对太湖地区稻田生态系统的NPK肥水平的合理性进行了评价，并结合田间试验的分析结果，探讨了生态经济施氮量，提出了太湖地区氮素可持续管理的建议。

In 2003,on the whole the soils in Wujiang were little acid, pH from 6.40±0.38 to 5.40±0.55now, and the trend of acid was in Tailake region. The available phosphorous in Paddyfield were significantly lower than. the other five land use patterns. As a result,controlling the phosphorous output form vegetable field mulberry yard and other dryland might be more significant to control the non-point pollution in Tailake region.

吴江市土壤基本上属微酸性土壤，2003年耕地监测中土壤pH值由1982年的6.40+0.38变为5.40±0.55，可见近20年来太湖地区普遍存在的酸化趋势；在稻田、林地、桑园、菜地、果园、旱地六种常见的土地利用方式中，稻田土壤速效磷显著低于其它五种利用方式中；因此，在控制太湖地区磷的面源污染上，控制菜地、桑园和其它旱地土壤磷的输出可能更为迫切。

The kinetics of degradation of healthy paddyfield ecosystem due to unreasonable fertilization are as follows.(1) The rice growth was interfered and the structure of microbe population was altered through applying excessive nitrogen fertilizer, while the yield of rice was decreased later and the secretion was reduced from rice root, which induced the Eh and the quantities of Bacterium and Actinomycetes declining, and the contents of MBC, MBN, MBP low in the soil. All of that made the capacity of accommodating nutrient weak in microbe ecosystem.

不合理施肥引起的稻田生态系统退化的动力学特征是：(1)重施氮肥首先使水稻植株生长受阻，同时改变土壤微生物种群结构，从而直接使水稻产量降低，稻田土壤生产力受损，并产生一系列不良次级反应：水稻生理活动减弱减少了根系分泌量，同时也降低了土壤Eh，使稻田土壤细菌、放线菌数量降低，MBC、MBN以及MBP含量下降，微生物保肥、供肥能力降低，从而土壤微生物生态系统功能弱化。
