交替题名 | Vertical Differentiation of Vegetation in Xiaojiang River Basin, Yunnan and Vegetive Measures of Cntroling Debris Flows |
英文摘要 | The Xiaojiang River basin in Yunnan Province is one of the regions where debris flows are the most typical in development and most harmful in China. The vegetation types of this locality belong to xerophytic subtropical broadleaf and needleaf evergreen forests of Western China. The basin is characterized by its great diff H and distinct vertical differentiation of vegetation. The execution of vegetative measures against debris flows must be based on these characteristics. Below 1600m above sea level lies the valley of Xiaojiang River with a dry and lot climate, where the vegetal cover is subtropical savanna scrub. Drytolerant and hottolernt trees and shrubs are chosen to make farmland-protecting plantations on the deposition fan of debris flow. On the seriously croded hillsides and foothills along the valley, drougth-enduring shrubs and low arbores are suitable for the water-conservation shrub forest. The low and middle mountains, between 1600 and 3000m above sea level, with a semihumid climate are the main ormation zone of debris flow. The vegetation consists of Yunnan pine forest and oak forest. According to the various conditions of vertical zones, different kinds of forests can be planted for water conservation. The subalpine zone between 3000m and 3900m above sea level has a humid climate. The major vegetation is fir forest, which is available for the conservation of water source. |
