Abstract: The objectiveness of the establishment of the leading position of the construction of forestry ecology environment is discussed in this paper, which is based on the affronting projects around the capital.

Thus the leading position of the construction of forestry ecology environment is established theoretically, and a concrete idea is put forward to push the affronting projects around the capital to a new step, based on the theory of constitutive development.

Key words: Affronting projects around the Capital, The construction of ecology environment, The leading position
