Effects of different harvesting ways on forest landscape ecology

The analytical results of the effects of different harvesting ways in artificial forest outing areas on forest landscape ecology show that the influence of clear cutting on forest landscape ecology is heavier than that of selective cutting, the impact of belt-shaped clear cutting on forest landscape ecology is more serious than that of lump-shaped clear cutting. The disposing form of cutting area in a sequent plot arrangement is better than that in an interval plot arrangement. The effect of clear cutting in a large cutting area on forest landscape ecology is graver than that of clear cutting in a small cutting area. The influence of selective cutting on forest landscape ecology increases as the intensity of selective cutting is higher, and the effect of selective cutting according to the diameter of wood on forest landscape ecology is heavier than that of intensively selective cutting. The influence of skidding operation on forest landscape ecology is related with skidding ways. The influen ces of different skidding ways are in the following sequence: walking tractor skidding＞pushing cart skidding＞dirt chute skidding＞winch skidding＞suspended cable skidding. The effects of skidding road on forest landscape ecology increase as the density of skidding road increases. And the countermeasures for decreasing effect of harvesting on forest landscape ecology are put forward.
