Abstract: The investigation was conducted on the forest resources of State-owned Forest Reserve in Hega Town of Huidong County.It was found that main species in the Reserve were Huashan pine, Yunnan pine and fir.In the Reserve,pure forests were main,with a part of mixed forest of various species. Growth conditions and site conditions were analyzed. The research results showed that the growth of tree species was directly related with the regional natural conditions and soil factors.High temperature,and low rainfall would cause slow growth of trees.thus economic benefit and ecological benefit would significantly reduce.
