With the increasing public attentions to ecological problems, greening projects in areas such as deserts, slopes, embankments and wastelands are more and more concerned by the society. One of the typical greening methods available is a fabric-spreading method in which an ecological fabric is laid on the surface of the area to be afforested. In some conditions (e.g. soil slopes, etc.), the method is to secure the soil/sands using the ecological fabrics, and plant growth materials are placed under the ecological fabrics; and in other conditions (e.g. deserts, etc.), the method is to place the plant growth materials on the ecological fabrics. However, in any conditions, the greening is made by means of the ecological fabrics, therefore, it is critical in the whole greening process how to secure the ecological fabrics. In the traditional methods, the ecological fabric is fixed to the area to be afforested by an anchor rod piercing the ecological fabric, in this case, the anchor rod may be loosened due to the decrease in the friction force between the anchor rod and the sands or soil, and even be drawn out from the sands or soil, leading to the unsteady fixation of the ecological fabric, and hence to the displacement of the fabric. Such a method merely relying on the anchor rod has a poor effectiveness, and is also not suitable for zones such as deserts. It is also provided a method for fixing the ecological fabric by making trenches in desert areas, but it is needed to fill ecological bags into the trenches to press the ecological fabric. However, the production of the ecological bags is complicated and costly, which apparently does not meet the current needs and is not convenient to marketing promotion.
