【摘要】 废弃土焦场地分布广泛,废弃程度高,污染严重,场地内除四周偶有植物分布外,寸草不生。为了提高土地利用率,需对废弃场地进行修复,植物修复因其操作简单、对周围环境扰动小、修复效果好、成本低等优点,被认为是废弃地修复的有效措施之一。总结了废弃土焦场地污染现状,综述了评价耐性植物的指标与方法,根据不同土壤类型(干旱土、湿成土)归纳适宜种植的耐性植物种类,可为生态修复废弃土焦场地选择适宜的植物种类提供一定的借鉴意义。更多还原

【Abstract】 The abandoned soil coke site is widely distributed, with high degree of waste and serious pollution. In addition to the occasional distribution of plants around the site, there is no grass. To improve the land use efficiency, it is necessary to repair the abandoned site. Because of its simple operation, small disturbance to the surrounding environment, good repair effect and low cost,phytoremediation is considered as one of the effective measures to repair waste land. The paper summarizes the pollution status of surface materials in waste sites soil coke sites for restoration plants, reviews the indicators and methods for evaluating tolerant plants, and generalizes suitable plant species according to different soil types(arid soil and wet soil), which will provide a certain reference for selecting suitable plant species for ecological restoration of abandoned soil coke sites.更多还原
