Total amount of microbe in polluted soil was also more than that in normal soil.

污染土壤中微生物的数量高于无污染土壤微生物的数量。

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。

Straw returned to field played a positive role in increasing soil insect communities with the largest contribution, primarily the amounts of individuals and dominant species of macro and meso/micro soil animal, especially Neanuridae and Isotomidae animals individual amounts increased by nearly 10 times.(3) Soil nutrien had a positive correlation with soil bacteria, azotobacter, ammonifying bacteria, cellulose decomposing bacteria and denitrifying bacteria. Straw returned to field could stimulate effective microorganisms growth and population quantity in the soil. The increase of microbe community amount is 15%~44% more than that of CK.(4) Soil nutrien had a positive correlation with soil phosphatase, urease and sucrase activities, and a negative correlation with catalase.

研究发现：(1)长期配施秸秆能提高土壤速效氮、磷、钾含量，平均分别提高15%、48%和22%；(2)配施秸秆对土壤昆虫群落呈正向作用且贡献最大，主要增加了大型、中小型农田土壤动物的个体总数和优势类群数量，尤其是疣跳科和等节跳科动物个体数量增加近10倍；(3)土壤养分与土壤细菌、固氮菌、氨化细菌、纤维分解菌和反硝化细菌呈正相关，秸秆还田激发土壤有益微生物的生长和类群数量，使土壤微生物类群数量比对照增加15%~44%；(4)土壤养分与土壤磷酸酶、脲酶、蔗糖酶活性呈正相关，与过氧化氢酶呈负相关，秸秆还田增强土壤蔗糖酶、磷酸酶和脲酶活性，特别是脲酶和蔗糖酶活性平均提高26.5%。

Soil enzyme and microbe play key roles in the cycle of mass and energy fluxes of soil ecosystem.

土壤酶和微生物在土壤生态系统的物质循环和能量流动方面都扮演着十分重要的角色。
