摘要
干热河谷不同岩土组成的坡地土壤水分状况差异较大 ,适合不同类型植被的生长。本文根据气候带和岩土类型的组合 ,进行了元谋干热河谷森林植被恢复适宜性分区。本区有 6种坡地岩土类型 ,3个气候带 ,分为森林植被恢复适宜区、较适宜区、较不适宜区、不适宜区和极不适宜区 5个区 ,其中适宜区和较适宜区面积 72 975 4 4hm2 ,占元谋干热河谷区总面积的 6 4 85 %。
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.
