PURPOSE: A slope tree-plantation structure and a construction method thereof are provided to stabilize soil, to protect slopes, to inhibit the growth of weeds, and to harmonize with surrounding natural environment. CONSTITUTION: A vegetation port(110) is arranged on a slope. The vegetation port is a geotechnical fabric, which is able to pass water and prevent the loss of vegetation base materials including soil and particulates, and is manufactured in a box form. A weed growth inhibition sheet(230) is arranged in the front side of the vegetation port, and inhibits the growth of weeds which has stronger propagation power than plantation seeds. A discharge prevention sheet(231) for moisture absorption has moisture holding capacity over a predetermined level. A strength reinforcement sheet(232) for the prevention of moisture evaporation enhances the strength of the weed growth inhibition sheet. A water proof sheet(233) has no absorbency and smoothly processes water-proofing of the external surface. The weed growth inhibition sheet has multiple through-holes(234). A port body(111) is manufactured in a box form, and is filled with soil. A blanket(112) for moisturization supplies moisture needed for sprouting the plantation seeds. A seed line net(113) has the plantation seeds inside.본 발명은 잡초의 생장이 억제되는 사면 녹화구조 및 그 시공방법에 관한 것이다. 본 발명의 잡초의 생장이 억제되는 사면 녹화구조는, 사면에 배치되며, 물은 투과하되 식생 기반재인 흙과 미립자의 유실을 방지할 수 있는 토목 섬유를 박스(box) 형태로 제작한 식생 포트(110)； 및 상기 식생 포트(110)의 전면에 배치되며, 녹화용 씨앗보다 번식력이 강한 잡초의 생장을 억제하는 잡초 생장 억제용 시트(130,230)를 포함한다.
