| 摘 要： | 通过对金沙江干热河谷实地考察与资料分析,初步划定了各地干热河谷的上限和层域范围。提出了地形是影响金沙江干热河谷水分变化的主要因子,确定以坡向和坡位作为金沙江干热河谷立地类型划分的主要依据,划分的立地类型分别是:坡上灌丛区,分坡上灌丛区阴坡类型、坡上灌丛区阳坡类型;坡下草丛区,分坡下草丛区阴坡类型、坡下草丛区阳坡类型;坡足冲积区;河谷平坝区。据此,针对干热河谷各立地类型的特点提出了相应的造林技术措施。

| Abstract: | Through site investigation analysis of the available data, the threshold value of dry and hot valley was preliminarily identified. A topographic characteristic was proposed as the main factor which affecting the water variation. Slope gradient and aspect were the main basis for dividing sites. The site condition of Jinsha river dry and hot valley was divided into seven different types. Specific strategies and techniques for reforestation at different site conditions were proposed. |
