1964年建立的青龙山林場,位于奈曼旗南部的浅山区。境内山丘起伏,沟壑纵横,土壤瘠薄,植被稀疏,水上流失严重,农牧业产量低而不稳。针对当地的自然条件,林埸从1965年开始,在经营管理好二万多亩国有林的基础上,积极开展植树造林,十六年内,共造林11.1万亩,保存8.4万亩,保存率达72%以上。其中油松造林9.4万亩,保存7.5万亩,现在已有2.5万亩郁闭成林,平均树高达4米以上。林場经营区内的82个山头已披上了绿装,改变了自然面貌,控制了水土流失,现在林地内每年为
Qinglongshan Forest Farm, established in 1964, is located in the shallow mountainous area in the southern part of Naiman Banner. Hilly territory, gully aspect, soil infertility, sparse vegetation, water loss is serious, low and unstable agricultural and livestock production. In response to the local natural conditions, starting from 1965, based on the management and operation of more than 20,000 mu of state-owned forest, Lin Pi actively carried out tree planting and afforestation. Within a period of 16 years, Lin Ya made a total of 111,000 mu of afforested land and saved 84,000 mu with a preservation rate of More than 72%. Among them, 9.4 million mu of Pinus tabulaeformis forests are preserved and 75,000 acres are preserved. There are now 25,000 mu of canopy forests closed, with the average tree reaching over 4 meters. 82 hills in the forest farm area have been covered in green garments, which has changed the natural appearance and controlled soil and water loss. Now,
