Soil microbial biomass carbon, microbial biomass nitrogen, soil basal respiration and metabolic quotient all showed a decreasing trend under more than 15 mg. kg - 1 cadmium or more than 200 mg. kg - 1 lead, respectively. soil dehydrogenase, urease and acid phosphotase activities have a significant decrease, and the activities of soil catalase and invertase taking sencond place, while soil protease activities showed stable state
隨重金屬濃度增加，各指標下降幅度各有差別，其中微生物生物量碳、微生物生物量氮以及基礎呼吸和微生物代謝商隨重金屬濃度增加而明顯下降；土壤脫氫酶、脲酶、酸性磷酸酶活性的下降幅度較為明顯，過氧化氫酶、蔗糖酶活性次之，蛋白酶活性較為穩定。 -
There were significant negative relationships among soil microbial carbon, microbial nitrogen, basal respiration, microbial metabolic quotient, urease activity, dehydrogenase activity, nitrification, nitrogen fixation and cadmium or lead concentration ( r0. 01 = 0. 765, r0. 05 = 0. 632 ). there was a close positive relationship between soil microbial biomass c : n ratios and cadmium or lead concentration ( r = 0. 8920 )
上述微生物活性指標與重金屬間的相關性分析表明，微生物生物量碳、基礎呼吸、微生物代謝商、脫氫酶活性與cd 、 pb的加入量呈極顯著負相關性，土壤微生物生物量c n比與cd 、 pb的加入量呈現極顯著正相關關系。
