“Yunnan’s evergreen warm coniferous forests account for 63% and 43% of the province’s forest land area and volume, but most of them are natural secondary forests with poor ecological and economic benefits, which hinders the improvement of forest stand quality and forest yield.
, Restricting the service function of the ecosystem, endangering the regional ecological security and the coordinated development of the regional economy
.

” said Su Jianrong, a researcher at the Institute of Resource Insects of the Chinese Academy of Forestry (hereinafter referred to as Zikun Institute) , said that the transformation of low-efficiency warm coniferous forests Recovery is a major issue urgently needed to be resolved in Yunnan forestry .

Recently, the Science and Technology Department of the State Forestry and Grassland Administration organized experts in Kunming to accept the special forestry public welfare industry scientific research project "Research on Reconstruction and Restoration of Inefficient Evergreen and Warm Coniferous Forests in Yunnan"

Introduced by Su Jianrong, introduced by the project team, Su Jianrong,

The project team studied the ecological service function zoning of evergreen warm coniferous forests in Yunnan, the types and classification standards of low-efficiency warm coniferous forests, the construction of inefficient warm coniferous forest reconstruction and restoration target models, and the construction of low-efficiency warm coniferous forests.
forest Improvement recovery technology demonstration
.

On this basis, a set of low-efficiency forest reconstruction and restoration technology systems that target vegetation types and dominate ecological service functions have been formed, focusing on supporting the reconstruction and restoration of low-efficiency forests, and effectively improving forest stand quality and forest land output

It is reported that the above-mentioned technical measures were tested and demonstrated 1,110 acres in Pu'er, Qujing, Yunnan and other places
.

The productivity of evergreen warm coniferous forests in the experimental demonstration forest area increased by 23.

The demonstration and promotion of this technological achievement will provide a basis for the classification of low-efficiency forests in China, provide scientific basis and technical support for the transformation of low-efficiency forests, and make a positive contribution to the construction of forest Yunnan, the realization of the goal of double forestry increase, and the promotion of forest farmers’ income and wealth.
