树环在2018年中旬落成于山东省济南市济阳区。北林风景建筑研究中心深度参与了济阳安澜湖公园的规划设计流程，与北林强大的景观设计专业团队合作，完成了园区内共计6座构筑物设计。这些建筑物承担公共景区的服务、休憩、赏花等各种功能，其中树环是最独特的一个。

Tree Loop was completed in the middle of 2018 in Ji Yang district of Ji Nan city, Shan Dong province. BFU Folie Architecture took part in the whole design procedures of Ji Yang An Lan lake park，thus 6 buildings had been built in this park，which cooperated with BFU professional landscape design team. These buildings perform various functions such as service, rest, and flower appreciation, among which the tree ring is the most unique one.

场地面对着济阳县刚刚新建的政府大楼，后者有着一个端庄而对称的地区政府大楼的典型形象。委托方希望在这个公园里有一个构筑物能够延续或者收束政府大楼的对称轴，在这里营造一个面向大楼的构筑物。安澜湖公园是一个城市新区的公园，周边的居民没有太多的休闲步行的去处，而这里则是居民游憩的一个便利选择。如何平衡居民需求和政府形象需求之间的平衡，是这个项目的难点和激发点。景观规划设计师在安澜湖公园中心设置了一个大水面回应这个公园的主题——水，同时在围绕水面的四周安排了儿童岛、游廊、亭榭等功能，树环的场地则处于场地最南侧。

The site was facing to a demure and symmetrical new government building. The client wanted to create a structure that faces the government building， which can continues or wraps around the axis of symmetry of government building. An Lan lake park is a convenient choice for residents to take a walk, as there are not many places for them to take a walk in the new area of the city. How to balance the needs of residents and government appearance is the difficulty and inspiration point of this project. A large water surface is set in the center of An Lan lake park, and arranged around the children’s island, veranda, pavilion and so on, which shows the theme of the park – water. the Tree Loop is located in the southernmost side.

在设计构思之初，景观设计师建议采用圆形的母题来回应政府大楼的照应问题，在场地周边设置了若干小型圆环栈道，并结合了荷花观赏池形成一系列圆形母题。我们尊重景观设计方的思路，认为圆环作为对称的形式，能够很好的回应大楼的轴线的呼应要求。同时，我们希望这个对称而完形的圆环能够掀起来，在其下方和上方形成静和动两种不同的空间体检，掀起的圆环能够让游人在不同的高程上获得不同的观景体验。

Initially, the landscape architect set up a number of small circular walkways and formed a series of circular lotus viewing pools，using circular motif to comply with the government buildings. We respect the idea of the landscape architect. As a symmetrical form, the circle can well respond to the axis of the building. At the same time, we hope that the circle can be lifted to form two different spatial examination of static and dynamic on below and above, and enable visitors to get different viewing experiences at different elevations.
