Four types of vascular plant communities were established on a wasteland of the copper mined tailings located in Tongling, East China. Biotic crusts, as an earlier stage of primary succession or a ground-layer within plant communities, became widely distributed on the surface of the tailings wasteland. The major aim of this study is to investigate the relationship between biotic crusts and the chemical properties of the upper tailings. According to the difference in vascular plant communities, authors divided the tailings wasteland into six types of areas, i.e., Hippochaete ramosissimum + Zoysia sinica community area (Type 1), Imperata cylindrica community area (Type 2), Z. sinica community area (Type 3), Cynodon dactylon community area (Type 4), biotic crust area (no vascular plants, Type 5), and bare tailings area (Type 6). Each of Types 1-4 was again divided into subtype with biotic crusts and subtype without biotic crusts. Eighty samples of the upper tailings (area: 20cm×20cm, depth: 0-3cm) were collected. Then, pH, electrical conductivity, organic matter, total nitrogen, available phosphorus, available potassium, and water content were determined. Results showed that the bare tailings were very deficient in nutrients. Plant communities growing on the tailings wasteland, especially plant communities with biotic crusts, could significantly improve the water content and chemical properties of the upper tailings. Organic matter, total nitrogen, extractable potassium, ater-soluble potassium, electrical conductivity, and water content in the upper tailings with biotic crusts (Subtypes 1.1, 2.1, 3.1 and 4.1) were 1.9-3.6, 3.3-10.7, 2.0-4.4, 2.4-5.9, 2.3-10.9 and 3.7-10.5 times that of the bare tailings, respectively. Compared to the bare tailings, pH values of the upper tailings of Subtypes 1.1, 2.1, 3.1 and 4.1 depressed 0.27-0.74 units. Compared to the four subtypes with biotic crusts, the effect of four subtypes without biotic crusts from the same type of vascular plant communities on the water content and chemical properties of the upper tailings was less. A comparison between Type 5 and Type 6 also indicated that biotic crusts could significantly improve the water content and chemical properties of the upper tailings. The contents of organic matter, total nitrogen, extractable potassium, water-soluble potassium, and water in the upper tailings of the former were 1.5, 2.0, 2.1, 2.4 and 5.0 times that of the later, respectively. Among four types of vascular plant communities, H. ramosissimum + Z. sinica community was the best and the C. dactylon community was the least in improving water content and chemical properties of the upper tailings. This investigation also indicated that the influence of biotic crusts on available phosphorus of the upper tailings was not significant. Increase of water content in the upper tailings caused by biotic crusts played a very important role in improving chemical properties of the upper tailings.

【期刊论文】The adsorption of basic dyes from aqueous solution on modified peat-resin particle

Modified peat was prepared by mixing thoroughly raw peat with sulfuric acid, and modified peat-resin particle was obtained, by mixing modified peat with solutions of polyvinylalcohol (PVA) and formaldehyde. In this paper, the adsorption of Basic Magenta and Basic Brilliant Green onto modified peat-resin particle is examined. The adsorption isotherm showed that the adsorption of basic dyes on modified peat-resin particle deviated from the Langmuir and Freundlich equations. The pseudo-first order, pseudo-second order and intraparticle diffusion models were used to fit the experimental data. By comparing the standard deviation, it was found that the intraparticle diffusion model could be used to well describe the adsorption of two basic dyes on modified peat-resin particle. According to the change of intraparticle diffusion parameter, the adsorption processes could be divided into different stages. The kinetics experiment also indicated that initial dye concentrations, particle dose and particle size could affect the adsorption processes of basic dyes.

在凡口1#铅锌尾矿库内共有10种植物自然定居,这些植物主要生长在尾矿库的边缘区域。植物在尾矿上的生长、分布明显受到表层尾矿某些物理性质如稳定状况、含水量等的影响,尾矿中的营养物质含量与植物的生长高度以及群落盖度有一定的关系。杜虹花(Callicarp apeduncu lata)体内的Pb、Zn、Cu 和Cd含量大小顺序为:叶>根>茎, 而盐肤木(Rhus chinensis)和美丽胡枝子(Lespedez amegacephala)体内的Pb、Zn含量则为:根>叶>茎。4重金属在植物体内的含量表现为:Zn>Pb>Cu>Cd。

在铜陵铜矿区堆存着大量的不同时期弃置的尾矿废弃物,形成大面积铜尾矿废弃地。为了解自然植物群落对铜尾矿废弃地酶活性的影响,对铜陵铜矿区6处不同时期弃置的铜尾矿废弃地进行了调查。结果表明,自然定居在尾矿废弃地上的植物群落类型能够显著影响表层尾矿中(0~5cm)的脲酶、芳基硫酸酯酶、碱性磷酸酶和脱氢酶的活性。位于木贼一中华结缕草群落和白茅群落下尾矿中的几种土壤酶的活性高于位于狗牙根群落和中华结缕草群落下的尾矿中酶的活性。在所测定的4种土壤酶中,碱性磷酸酶和脱氢酶的活性高于脲酶和芳基硫酸酯酶的活性。相关分析表明,4种土壤酶的活性与表层尾矿中的腐殖质、总氮、有效磷、速效钾含量以及电导率表现出显著正相关,而芳基硫酸酯酶和脱氢酶与pH之间存在着显著负相关。强烈氧化的表层尾矿不仅具有极端贫瘠的养分条件,同时也具有极低的土壤酶活性。
