The present invention relates to a grass protection mat, and to a method for constructing a grass protection mat. The grass protection mat comprises: a plurality of body units having grass passing spaces formed therein； and a shrinkage-expansion compensation-type connection means for connecting the plurality of body units to ensure shrinkage-expansion compensation of a unit mat. At least four adjacent unit mats are directly connected through one or more shrinkage-expansion compensation connection means to form one group. The mat can be easily produced, and costs are reduced.본 발명은 잔디 보호 매트에 관한 것으로서, 잔디통과공간이 형성된 복수의 바디부； 및 상기 복수의 바디부 사이를 단위 매트의 수축-팽창 보상을 위해 연결하는 수축-팽창 보상형 연결수단을 포함하는 것을 특징으로 한다.
