LITHOLOGIC TYPES ON HILL SLOPES AND REVEGETATION ZONING IN THE YUANMOU HOT AND DRY VALLEY

Zhang Xinbao Yang Zhong Zang Jianping (Chengdu Institute of Mountain Hazards and Environment, Chinese Academy of Sciences & Water Resources Ministry Chengdu610041)  
Soil moisture conditions and vegetation types are greatly influenced by the lithology on hill slopes under the hot and dry valley climate. By combination of climate and lithology types, the Yuanmou hot and dry valley, where there are six lithology types and three climatic types, is divided into five availability zones for artificial forests: available zone, fairly available zone, fairly unavailable zone, unavailable zone and very unavailable zone. The available zone and fairly available zone have an area of 72 975 44?hm\+2, which accounts of 64 85% of the total area of the Yuanmou Hot and Dry Valley.
