| 1 | 城市垃圾堆肥的生态效应与对策研究显示文摘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。 | 范海荣 华珞 傅桦 王学江 | 2004 | 土壤2004，36，5： | 20 |
| 2 | Uptake, Distribution and Accumulation of Copper in Two Ecotypes of Elsholtzia显示文摘Two ecotypes of Elsholtzia, Elsholtzia splendens and E. Argyi, are dominant plants growing on Cu and Pb-Zn smelters, respectively. Samples of the two ecotypes and the corresponding soils from fields of a copper mining area and a Pb-Zn mining area of Zhejiang Province, China, were analyzed to investigate Cu or Zn tolerance of these two ecotypes. Effects of nine Cu levels (0, 5, 10, 20, 40, 80, 160, 240 and 320 mg Cu L-1 as CuSO4@SH20) on growth and uptake, translocation and accumulation of Cu in these two ecotypes were examined in a solution culture experiment. The experimental results showed that dry weights (DW) of shoots and roots were depressed, and growth of E. Splendens was less depressed tha n that of E. Argyi when treated with ≥ 5 mg Cu L-1. Concentrations of Cu in shoots of E. Splendens and E. Argyi exceeded 1 000 mg kg-1 DW at ≥ 40 mg Cu L-x. The maximum Cu accumulated in the shoots of Gu-treated E. Splendens and E. Argyi reached 101 and 142μg plant-1. Furthermore, analysis of plant samples from the fields showed that these two ecotypes can tolerant excess heavy metals and produced high dry matter, and E. Splendens can accumulate 11.7 mg Cu plant-1 grown on the Cu smelter. Therefore, E. Splendens and E. Argyi could be good plants for phytoremediation. | JIANGLi-Ying YANGXiao-E YEZheng-Qian SHIWei-Yong | 2003 | Pedosphere2003，13，4： | 16 |
| 3 | 粉煤灰对土壤性质和草坪生长的影响显示文摘为使粉煤灰的利用避开食物链,探讨了粉煤灰在草坪业中的应用。盆栽试验结果表明:粉煤灰施加到土壤后,具有明显的降低土壤粘粒含量,增加速效P、全P及部分金属元素(K、Ca、Mn、Zn、Cu、Cd和Pb)含量的作用,这一效果随粉煤灰施用量的增加而增加。同时,各个处理中的重金属元素Zn、Cu和Pb含量均低于“土壤环境质量标准值”一级标准,但为避免对环境的潜在危害,粉煤灰施加量应该控制在317.29g/kg以内。在施灰量300g/kg(重量比)的土壤中,草坪生长和产量最佳;300g/kg是粉煤灰用作草皮基质的最佳施加比例。 | 郑海金 曾峰海 欧立业 | 2005 | 土壤2005，37，2： | 13 |
| 4 | 城市垃圾的堆肥处理显示文摘本文介绍了城市垃圾的处理现状及综合利用的基本方法,重点介绍了城市垃圾的堆肥处理。本文还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;最后说明判断了城市生活垃圾堆肥腐熟度综合指标。 | 张肖 龙其霖 | 2013 | 科技信息2013，，26： | 1 |
