Different types of plantations were observed in Baishilazi National Nature Reserve, Liaoning Province, for 34 a. The environmental
quality of
Abies holophylla plantations was analyzed under different cutting systems. Analysis factors included soil erosion rate, humification degree
of litters, and water hold capacity. The surface soil loss of clear cutting area was 19000t·km
−2·a
−1 more than that of selective cutting area. The content of soil organic matter in board-leaved—
Abies holophylla forest was 4.62% more than that in pure stand, and the water hold capacity of the mixed forest was 1.43 time of that of pure
stand. The mixed forest of board-leaved—
Abies holophylla by selective cutting can upgrade the ecological environment quality.
