摘 要：
在滨海淤泥质滩涂生态系统中采取以植物绿化为主的生态恢复工程，由于缺少土壤改造的适宜的资源，常成为工程正常实施的主要困难．通常情况下采用的从周边地区购买农田种植土的方法，不仅破坏采土区的生态环境，而且造价高．天津经济开发区通过对其周边环境中大量存在的海湾泥、碱渣和粉煤灰等固体废弃物资源的研究发现，当它们单独存在时，都不是 合适的土壤资源，但当以适当比例配合后，其混合物却更适合植物的生长．用它作为土壤资 源，将不仅能解决大量固体废弃物对滨海生态系统的污染问题，而且还可以减少对周边地区 生态环境的破坏，降低生产成本．海湾泥与碱渣和粉煤灰的最佳推荐比例为３∶１．

摘 要：
Generally, the ecological rehabilitation engineering out of the costal mudflat ecosystem was accomplished mainly by Virescence, however, the lack of proper soil resources for reformation of the costal mudflat was the main difficulty.To bring in good soil from neighbor farmland was both costly and ecological damage. In TEDA (Tianjin Economic-Technological Development Area), there are huge amount of solid wastes, such as bay mud, alkali slag and flyash. Each of them is not suitable for any plant to grow if existed alone. However, when the three wastes were mixed at certain proportion, the mixture is more suitable for plant growth than solonchak. So the mixture could be utilized as soil resources .It could solve the problems of solid wastes pollution and the damage to around ecosystem as well as reducing the cost of rehabilitation. The recommended proportion for bay mud, alkali slag and flyash was3∶1.
