A sand drift prevention method in which a plurality of columnar sandbags made of a tubular knit fabric are placed so as to cross over one another, and in such a pitch that 3 to 30 sandbags are disposed for every ten meters, and in which the cross-sectional area of each of the columnar sandbags is 10 to 400 cm. A method of forming and improving the vegetation in sandy soil in which drift of sand is prevented by the sand drift prevention method, a plant desired to grow is grown in the sandy soil surface exposed as being surrounded by columnar sandbags placed so as to cross over one another. A tubular knit fabric for a columnar sandbag employed in these methods, and, in particular, the tubular knit fabric knitted by use of a polylactic-acid fiber.

Sand drift prevention method, method of forming and improving vegetation in sandy soil using the same, and tubular knit fabric for columnar sandbag

To provide a fiberboard capable of reducing a load on the environment at all states of producing, using, and abolishing and moreover having a high degree of bending strength and a high bending-strength retention rate at high temperature and high humidity so as to be usable for an automobile interior material or building material and a fiber-board producing method. The fiberboard is formed by mixing natural fiber with polylactic acid resin serving as a binder and has an apparent density of 0.2 g/cm.
