Design of test plots with different interference types.

Interference mode	Sample plots	Elevation (m)	Tree species	Canopy density	Total forest storage (m3/ha)	Slope	Aspect
Overcutting disturbs the plot	Gradual cutting sample S1	969	Pure betula platyphylla	0.76	9.8995	2°	Southwest slope
	Gradual cutting sample S2	973	9 Betula platyphylla 1 Larix gmelinii	0.642	11.9829	2°	Western slope
	Gradual cutting and replenishing sample plot S3	940	8 Betula platyphylla 2 Larix gmelinii	0.64	5.99095	2°	Southwest slope
	Gradual cutting and replenishing sample plot S4	910	6 Larix gmelinii 4 Betula platyphylla	0.6	9.1455	4.5°	Southwest slope
Artificial modification interferes with the sample	Modified sample plot ML by 50 m artificial larch forest belt	710	9 Larix gmelinii 1 Betula platyphylla	0.6	16.1702	8°	West slope
	Unchanged, pure natural forest MB	705	9 Betula platyphylla 1 Populus davidiana	0.6	11.3353	8°	West slope
Fire disturbance	Heavy burn Sample plot H1	940	9 Betula platyphylla 1 Larix gmelinii	0.3	0.4258	4°	West slope
	Moderate fire Sample plot H2	940	Pure betula platyphylla	0.44	1.5504	2.3°	West slope
