Xining of Qinghai Province explored an afforestation model for the plateau and drought areas in greening the North and South Mountains. With the establishment and implementation of the “green-based principle, irrigation-based principle, the principle of acting according to local conditions, and the principle of matching species with the site”, and commitment to the “centralized management of mountains, ravines and contiguous areas”, they first planted Hippophae rhamnoides Linn, Tamarix ramosissima, Caragana korshinskii and other shrubs, then more than 10 local tree species, including Tamarix chinensis, Prunus armeniaca, Qinghai spruce, Sabina przewalskii, and Pinus tabuliformis Carrière, to form a plant community featuring a combination of trees, shrubs and weeds, relatively abundant in diversity and stability in structure. As of 2014, the area of forest land has increased from 980 ha in 1989 to 10,880 ha , and with the additional 3,933 ha of shrubbery land, the forest coverage rate has increased from 5.3% to 79%. Thus a mountain forest ecosystem with the majority of the local needle-leaved tree species, combination of trees, shrubs and weeds, and mixture of broadleaf and conifer forests has been initially built up.

In view of the singleness of the tree species, the decline in biological diversity, and the serious waste of forest land productivity in the Saihanba plantations of Hebei Province, the Forest Farm conducted the targeted tending of the artificial Larix principis-rupprechtii pure forest adopting the close-to-nature management selective cutting mode. The tender operation to target forest was carried out once every 5 years, so that the target tree density was finally maintained at about 450 plants /ha after 3-5 times. Then the density of the target trees was gradually reduced to 225-300 plants / ha. Under the forest canopy, the shade-tolerant species, spruce, was planted, while Pinus sylvestris was planted in the edge of the forest; the management of forest regeneration layer was strengthened by implementing timely cutting, irrigating and weeding operations, so as to promote the growth of new seedlings. The uneven-aged stratified mixed stand of Larix principis-rupprechtii, spruce and Pinus sylvestris has effectively enhanced the quality of the stand and improved the function of ecological service. There were large diameter tree species of Larix principis-rupprechtii in the upper layer, an even distribution of spruce, Pinus sylvestris and other tree species in the middle, and the dense vegetation in the lower. The targeted DBH of Larix principis-rupprechtii, spruce and Pinus sylvestris were 40+cm, 55+cm, and 50+cm, respectively. (Hebei Provincial Department of Forestry)

In recent years, Hebei Mulan Weichang State-owned Forestry Bureau has got rid of the backward technology system, promoted scientific silviculture, and made full use of existing forest resources for close-to-nature management, producing ecological benefits as well as moving towards a healthy direction.
