＂Design＂ is the soul of the construction for an engineering project. And the design phase is the main phasewhich can make up the value of the construction and the construction＇ s use. It can also influence the investment of construction. It is the crucial cycle which can influence the quality of construction. Therefore, the important part of the supervision for construction is to build a good forestry ecological construction project. To supervise the design of the project is the common way around the world. This article will discuss the importance of the design supervision for the forest engineering project management, the importance of the tasks and methods of work. At the same time, we would like to show our views about how to develop the design and supervision.
