PURPOSE: An ascidians transplanting tool and a marine ecosystem restoration method using the same is provided to make the use of the tool simple and to firmly fix an Ascidians transplant seeding on the ocean floor bedrock and sand despite having a simple structure. CONSTITUTION: A support stand(10) is combined by a hinge shaft(20) with two sticks arranged in an X-shape or cross-shape. A compressed spring(30) forms an inner angle of 45-135 degrees with two sticks combined to both sides on each sticks forming the support stand without compression. A penetration hole(40) is formed in which the ascidians are inserted and fixed in the middle of the hinge shaft. One or more penetration holes are formed to insert and fix the Ascidians on the support stand. A spike(50) is equipped at each end of the two sticks which forms the support stand. The ascidians transplanting tool additionally contains a body for a spike fixation in a bar shape combined in a downward direction to have an inner angle of 60-120 degrees at the end of each stick which forms the support stand. The spike is fixed to form an inner angle of 30-120 degrees in an upward direction with the outer side of the spike fixation body. A length extension means(70) is additionally equipped to extend the length of a stick at the each end of two sticks which form the support stand. The two sticks for the support stand are made of a stainless steel, FRP, or an reinforced plastic material.2개의 막대가 X자형 또는 열십(十)자형으로 힌지축에 의하여 결합된 지지체, 및 상기 지지체를 형성하는 2개의 막대 각각에 일단부씩 양단부가 결합되어 압축되지 않은 상태에서 상기 2개의 막대가 45~135도의 내각을 형성하게 하는 압축 스프링으로 구성되며, 상기 힌지축 중심에는 해초류가 삽입 고정될 수 있는 관통 구멍이 형성된 것을 특징으로 하는 해초류 이식 도구 및 이를 이용한 해양 생태계 복원 방법을 제공한다.
