| 摘 要： | 本文分析了城市垃圾堆肥的生态效应,其中包括肥力效应:提高土壤养分,改善土壤的理化性质;生物效应:改善土壤的微生物特性,提高植物的产量和品质;环境负效应:造成土壤的沙化、盐渍化、重金属积累等;环境正效应:修复被污染的土壤,防止水土流失;并阐述了垃圾堆肥环境效应的预防措施。最后提出了城市垃圾堆肥的发展对策:提高垃圾堆肥的质量,发展有机无机复合肥。

| Abstract: | Ecological effect of urban waste compost are analyzed, including its fertility effect: increasing soil nutrients and improving soil physical and chemical properties; its biological effect: improving soil microbiological properties and crop yield and quality; its negative environmental effect: causing soil desertification and salinization, and heavy metal accumulation etc; its positive environmental effect: remediation of contaminated soils, and preventing soil and water losses. Countermeasures to its negative environment effect are also elaborated. In the end, it points out improving quality of the compost and developing organic-inorganic compound fertilizer are the ways to develop waste compost. |
