摘　　要：为探讨厌氧消化处理后的城市污泥和园林落叶在园林方面利用的可行性,采用盆栽实验研究城市污泥与园林落叶不同配比复配后作为绿化基质对黑麦草种苗生长的影响。经过测定,厌氧消化处理后的污泥中重金属含量均达到国家园林绿化标准。落叶的质量分数在60%时,复配基质所含总氮、总磷、总钾与营养土较为接近。落叶的质量分数在40%和50%时,黑麦草的形态指标与生理生化指标最好。The feasibility of utilization of urban sewage sludge after anaerobic digestion process and garden leaves in landscape architecture is discussed, the pot experiments are carried out to study the effects of different ratio of urban sludge and garden leaves as green matrix on seedling growth of ryegrass. The content of heavy metals in the sludge after anaerobic digestion meets the national standards. When the mass ratio of leaves is 60%, the total nitrogen, total phosphorus, total potassium in the complex matrix is close to nutrient soil. When the mass ratio of leaves is 40% and 50%, the morphological indexes,physiological and biochemical indexes of ryegrass are the best.
