The Guxian Forest Farm in Chongyang County is located in the middle mountain area of E’nan and belongs to the branch of Mufu Mountain. The existing afforestation area is 19,063 mu, of which 11,486 mu is fir, 3,436 mu is pine and 300 mu is coniferous mixed forest. Developmental Law and the Superiority of Mixed Pine and Pine and Their Relationship. We selected 60 years of afforestation, the same afforestation density of fir cedar pure forest, and mixed forest of 400 square meters of representative plots to investigate. 350 meters above sea level, located in the mountainside, soil, PH value of 5.0-5.6, humus deep. Afforestation density of 250-300 plants / mu, reclamation three times before closing, 1964 - 1965 has closed forest.
