| 中文摘要: |
| 用模糊综合评价方法评价岩滩水库4个类型监测区水质周年变化。结果表明，各监测区周年水质均为芋类。影响水质的主要因子是TN，TN 超标倍数（WTN）分析表明，在相同水质等级（芋类）内，汉达监测区水质最好，TN 超标倍数（WTN）值处于0.096~0.883 范围；江栋监测区水质最差，TN 超标倍数（WTN）值处于0.557~1.358 范围。水质周年变化与大水面养殖状况关系密切，建议在大水面开展鱼类养殖、促进库区移民增收的同时，充分保护养殖水域环境，提高大水面资源综合、可持续利用水平。 |
| 英文摘要: |
| Intensive livestock and poultry manure (ILPM) is one of the main sources of modern organic fertilizers in
China, however, it contains much more heavy metals and other pollutants. Long-term application of ILPM may influence the
structure and function of microbial community in cultivated soil. In order to understand the effects of long-term application of
ILPM on soil microbial community function, we conducted an experiment using the BIOLOG micro plate method. All the soil
samples were collected from two long-term experiment plots with ILPM or chemical fertilizer in Haian county of Jiangsu
province. Results showed that the average well color development (AWCD) in soil with application of ILPM was higher than
that of soil with chemical fertilizer in two kinds of plots. Compared with soil in application of chemical fertilizer treatment,
soil microbial community species richness and dominance in treatments with IPLM did not change significantly, but species
evenness significantly increased. The utilization ability of soil microbes on amine, carbohydrate and amino acid in treatments
with IPLM was higher than that in treatments with chemical fertilizer. Results of principal component analysis and
correspondence analysis also showed that the direction and ability of soil microbial community carbon resources utilization
were significantly different between treatments with ILPM and with chemical fertilizer. Our results indicated that application
of intensive livestock and poultry manure could change the functional diversity of soil microbial community. |
