Abstract：
The development of anthroposols has been proposed as a new environmentally friendly approach to ensuring the successful revegetation of phosphate mining sites. The phosphate industry\'s by-products, including phosphogypsum (PG), phosphate sludge (PS), and sewage sludge (SS), can be valuable resources in restoring the ecological balance of mined soil areas. The aim of this study was to safely and sustainably restore the ecological integrity of the phosphate mining site through the evaluation of nutrients and heavy metals dynamics in soil and plant tissues of three tree species and treated by-products containing 65 % PG, 30 % PS, and 5 % SS. The tree species used were Pistacia atlantica, Schinus molle, and Eucalyptus globulus. The experimental layout was a randomised complete block design with six replicates and three treatments. Growth diameter, height, nutrient uptakes and heavy metal dynamic were evaluated from the rhizosphere soils and plant tissues over two years. Hierarchical head maps of correlations between the measured growth parameters, soil and nutrient uptakes of the tree species were analysed using a phylogenetic generalised linear mixed model. S. molle and E. globulus had higher average diameter and height than P. atlantica plants. P. atlantica and S. molle showed greater nitrogen, phosphorus, potassium, calcium, and magnesium concentrations than E. globulus trees. Tree growth parameters were closely linked to soil nutrient bioavailability. The heavy metal accumulation ratio was higher in the E. globulus and S. molle leaves than in stems. Using by-products could be valorised for rehabilitating mine sites together with E. globulus and S. molle species.
摘要：
已提出开发蒽酯醇作为一种新的环保方法，以确保成功恢复磷酸盐矿区的植被。磷酸盐工业的副产品，包括磷石膏（PG），磷酸盐污泥(PS)，和污水污泥(SS)，可以恢复矿区土壤生态平衡的宝贵资源。这项研究的目的是通过评估三种树种的土壤和植物组织中的养分和重金属动态以及含有65％PG的处理过的副产品，安全，可持续地恢复磷酸盐矿区的生态完整性，30%PS,5%SS。使用的树种是黄连木，SchinusMolle,和球桉树。实验布局是随机的完整区组设计,具有六个重复和三个处理。生长直径,高度,在过去的两年中，从根际土壤和植物组织中评估了养分吸收和重金属动态。测量的生长参数之间的相关性的分层头图，使用系统发育广义线性混合模型分析了树种的土壤和养分吸收。S.molle和E.globulus的平均直径和高度均高于Atlanta植物。Atlantica和S.mole显示出更大的氮，磷，钾，钙，和镁的浓度比E.球藻树。树木生长参数与土壤养分生物利用度密切相关。球藻和S.mole叶片中的重金属积累率高于茎中的重金属积累率。使用副产品可以与E.globulus和S.mole物种一起恢复矿山。
