Forest classification management and protection

Key ecological public welfare forest: the forest within the first layer ridge of Menglu River, the first level tributary of Nenjiang river system, and Beishi River, the second level tributary of Nenjiang river system, are classified as key ecological public welfare forest, with a total area of 590220 mu; the source catchment area of Xuhe River, the second level tributary of Heilongjiang Province, and the forest within the first layer ridge on both sides of the river are classified as key ecological public welfare forest, with an area of 210900 mu Mu. The total area of key ecological public welfare forest is 801120 mu, accounting for 39% of forestry land. The secondary forest is water conservation forest.

The general ecological forest is distributed in the first ridge line of the second and third tributaries of Heilongjiang and Nenjiang rivers. The ecologically fragile forest on both sides of the river covers an area of 940245 mu, accounting for 46% of the forest land.

Commercial forests are mainly distributed in Machang and Xiaoxigou construction area, with flat terrain, good site conditions, relatively concentrated and contiguous. Poplar (Birch) soft broad-leaved forest on the flat ridge, with a total area of 305220 mu, accounting for 15% of the forest land area.

All the national public welfare forests in the forest farm are shelterbelts, with a total area of 801120 mu, including 684345 mu of woodland, 116760 mu of shrubbery, 15 mu of unforested woodland, and the secondary forest is water conservation forest.

The key shelterbelts are mainly located in the headwater catchment area of Gongbiela River tributary in the upper reaches of Xuhe River, the first tributary of Nenjiang River, the headwater catchment area of upper reaches of Luhe River, and the forests within the first ridge line on both sides of the river. The forests in these areas play an important role in water conservation and soil and water conservation.

Birch pure forest and broad-leaved mixed forest are the main protection forests. Due to the over cutting in the past, the forest succession was a natural secondary forest dominated by Mongolian oak broad-leaved mixed forest. There are more young forest, less middle and near mature forest, more over mature forest and poor stand quality. Among the key shelterbelts, there are 684345 mu of woodland with a total volume of 2236230 cubic meters. In this part of the area, the valleys are crisscross, the rivers crisscross, and the mountains are steep. The forest plays a key role in water conservation and soil and water conservation.
