1 . ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study . little difference in total counts of bacteria , actinomycetes and fungi was observed between the contaminated and the non - contaminated soil . compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil 一、甲基對硫磷長期污染對土壤微生物的生態學效應研究了有機磷農藥甲基對硫磷長期污染對土壤微生物的影響,實驗表明:土壤細菌、放線菌、真菌總的數量影響不大;自生固氮菌和反硝化細菌數量減少;氨化細菌、亞硝化細菌、硝化細菌的數量在污染土壤中卻有所增加;與對照土壤相比,污染土壤呼吸作用下降了29 . 93 ;氨化作用和硝化作用強度得到增強。

But so far , there have not report about forest soil microbe and soil enzymatic activity in westen sichuan . the study ' s object is bitch forest . spruce forest , fir forest , chrysanthemum alp , willow community and two couch grass , so the research of the soil microorganisma , soil enzymatic activity in the subalpine coniferous forests in western sichuan is significant to china . the result shows that : 1 . in the soil , the relativity of the soil microbial puantity is very prominence , the relation with the quantity of the soil microorganism is that : bacillus > actinomyceto > fungi ; the amount of the microorganism of physiological group sequence ranging from high to low is : aminate > bacteriumazotobacter > denitrify bacterium > nitrobacteria > cellulose decomposing bacteria . under the different vegetable community , the microbial quantity is that : s5 > s7 > s6 > s1 > s2 > s4 > s3 其中,各群落中土壤微生物總數以白樺純林( s5 )群落最多,每克干土中的含菌量達66 . 13 10 ~ 6個;其次是冷杉針葉林( s7 )群落,每克干土中的含菌量達43 . 41 10 ~ 6個:第三是云杉針葉林( s6 )群落,每克干土中的含菌量達42 . 85 10 ~ 6個;第四是繡線菊-茅草群落( s1 ) ,每克干土中的含菌量達33 . 83 10 ~ 6個;第五是高山柳群落( s2 ) 、茅草( s4 )群落,每克干土中的含菌量分別為33 . 33 10 ~ 6個和33 . 08 10 ~ 6個;第六是茅草群落( s3 ) ,土壤微生物數量最少每克干土中的含菌量僅為23 . 12 10 ~ 6個。

2 . the population of functional bacteria in water body varied with adding cm . when the use of cm was 4g , the amount of the total bacteria and phosphorus bacteria were maximum in the fourth day , the amount of denitrifying bacteria were maximum in the tenth day ; when the use of cm was 1g , the amount of ammonifying bacteria were maximum 復合微生物的加入引起水體中的微生物功能菌群數量變化,其中復合微生物添加量為4g時,實驗第4天,總菌和磷細菌達到最高峰,第10天,反硝化菌達到最高峰;當復合微生物添加量為1g時,實驗第4天氨化菌達到最高峰。
