中文摘要 | 為了解燃油火力發電廠對微生物生態及環境品質之影響,以協和火力發電廠及其周圍為對象,採討土壤中細菌、放線菌、真菌、纖維素分解菌、溶磷菌和固氮菌在廠區內外之變化。結果發現協和火力發電廠及其周圍土壤,廠區內土壤pH值介於5.10∼7.81,而廠區外介於4.00∼5.33。廠區內土壤水分含量介於8.08∼31.12%,廠區外介於19.96∼33.49%。上層土壤中所含微生物一般比下層土壤高,季節性對土壤微生物數目之影響不顯著,可能因土壤pH、水分含量、溫度等變化不大所至。在廠區內每克乾重土壤含細菌3.64×10�捸�5.16×10�蔬茧葚芋A放線菌1.75×10�纂�1.10×10�雁茧葚芋A真菌6.72×10�纂�8.78×10�雁茧葚芋A纖維素分解菌佔總菌數25.3-60.2%,溶磷菌佔8.4-39.0%和固氮菌佔32.5-81.3%。在廠區外每克乾重土壤含細菌5.52×10�捸�2.14×10�蔬茧葚芋A放線菌8.26×10�纂�7.25×10�雁茧葚芋A真菌3.49×10�纂�2.74×10�雁茧葚芋A纖維素分解菌佔總菌數10.8-12.9%,溶磷菌佔9.1-18.5%和固氮菌佔16.0-34.8%。由統計分析發現,上下層土壤細菌含量有顯著性差異者約佔37.5%,而放線菌和真菌有顯著性差異者分別佔36.0和26.7%。距煙囪0.5km之林地土壤微生物含量最高,而距煙囪4.1km處之坡地含量最低,且部份呈顯著性差異。土壤微生物數量及分布與煙囪距離之關係並不明顯,廠區內土壤細菌、放線菌、真菌、纖維素分解菌、溶磷菌和固氮菌含量比廠區外高且呈顯著性差異。 |
英文摘要 | To investigate the effect of thermal power plant on the microbial ecology and the environmental quality, the Hsieh-Ho Thermal Power Plant was chosen and the populations of microbes including bacteria, actinomycetes, fungi, and cellulolytic, phosphate-solubilizing and nitrogen-fixing microbes were selected as the parameters of microbial ecology. The pH values of the soil sample collected from inside and outside of the plant were 5.2-6.2 and 4.0-5.3, respectively. Moisture content in plant area was lower than that in the surrounding area. Microbial populations of the topsoils were higher than those of the subsoils. Each gram of soil contained 3.64 × 10 �捸�5.16 × 10�� colonies of bacteria, 1.75 × 10��-1.10 × 10�� colonies of actinomycetes and 6.72 × 10�纂� 8.78 × 10�� colonies of fungi in the plant area; while they were 5.52 × 10�捸� 2.14 × 10��,8.26 × 10�纂�7.25 × 10�� and 3.49 × 10 �纂�2.74 × 10�� colonies of bacteria, actinomycetes and fungi, respectively, in the surrounding area. The effect of seasonal change on microbial populations was not significant. The ratio of cellulolytic, phosphate-solubilizing and nitrogen-fixing microbes to the total count in the plant area was also higher than that in the surrounding area, and some of them had significant differences. From the statistical analysis, the effect of thermal power generator on the population and distribution of microbes was significantly different. |
