摘要: 多年的观测资料表明,森林采伐后,生态条件确有变化。如温度变幅增大,土壤变得干燥,蓄水性能减弱,灌丛草甸入侵等。如不进行人为干预,必然会导致生态环境恶化。因此,应进行合理的采伐和及时更新。那样,则三、四十年后,大多数迹地能恢复森林,建立新的生态平衡。
Abstract: The materials studied in many years have shown that there was a worse change of ecological conditions on the cutting areas in the west subalpine belt of Sichuan province. For example, there is great difference in temperatures and the soil moisture percentage decreases. The water-holding power is weaker than before.Some shrubs and weeds invaded, etc. If no better management given to that area the condition will be worse and worse. So that we shall cut reasonably and regenerate on time in woodland. Then, the forest will be reestablished on most cutting areas and a new ecological balance will be taking place.
