| 摘 要： | 氮肥的施用在农业生产和产量增加上具有重要作用.然而,自从20世纪90年代以来,投入到农业生态系统中的氮肥已经成为氮素的重要污染源.低的氮肥利用率伴随着高的环境污染是世界范围内氮肥使用中普遍存在的现象.过度的氮肥使用已经对空气、土壤和水体等环境造成了严重污染,同时也在很大程度上扰乱了全球的生物地球化学循环,导致了生物多样...

| Abstract: | Present status of nitrogen fertilizer application,nitrogen environmental risk for atmosphere,soil,water and ecosystem was reviewed.Especially,the relationships between nitrogen application,nitrate loss and soil acidification were discuss in detail.And the relationships between nitrogen application,emission of greenhouse gas and hypertrophic problem in the water and the relationships between nitrogen sink and nitrogen nutritional balance in terrestrial ecosystems as well.Some suggestion was put forward for f... |
