PROBLEM TO BE SOLVED: To provide easily a partition structure of a tree-planting area with good appearance by easy work without taking trouble to adjust an arrangement state of partition members in a corner section.SOLUTION: The partition structure of a tree-planting area includes a straight-line partition member which partitions in a straight-line form a tree-planting area for planting greening plants and a non-greening area, and a corner member which is covered on a pair of the straight-line partition members and connects the end parts each other in a bent state. The end parts of a pair of the straight-line partition members are arranged in an arbitrary arrangement condition, and the corner member is covered and fastened so as to bridge between the end parts, in a range where the corner upper part of the corner member is arranged above the partition upper part of the straight-line partition member, and a range where the corner side part of a storage partition member is arranged outside the partition side part of the straight-line partition member.【課題】コーナー部分での仕切部材の配置状態を調整する手間をかけること無く、簡易な作業で、見栄えの良い緑化エリア仕切構造を簡易に提供する【解決手段】緑化植物を植栽可能な緑化エリアと非緑化エリアとを直線状に仕切る直線仕切部材と、一対の直線仕切部材に被せられて端部同士を屈曲接続するコーナー部材とを有する緑化エリア仕切構造において、コーナー部材のコーナー上部が直線仕切部材の仕切上部の上側に配置される範囲内、及び収納仕切部材のコーナー側部が直線仕切部材の仕切側部の外側に配置される範囲内において、一対の直線仕切部材の端部同士を任意の配置状態で設置し、それら端部同士間に架け渡すようにコーナー部材を被せて固定する。【選択図】図１
