摘  要：
为对云南元谋干热河谷退化生态系统进行治理,选择罗望子作为治理该区退化坡地的主栽树种,营建了罗望子林人工植被系统。通过对该系统相关林木的生长,土壤、大气等生态因子大量观测数据的比较分析表明:在元谋干热河谷区,选择罗望子作为主栽树种营建罗望子林人工植被系统治理退化坡地的生态效应明显。主要表现为:(1)土壤退化得到明显控制(土壤物理性状获得改善,土壤肥力得到提高);(2)水土流失程度减轻;(3)干热气候得以调节,风速有所降低;(4)植物缺水程度减轻,能够正常健康生长。

摘  要：
In order to manage the degrade eco-system of Yuanmou dry and hot valley areas of Yunnan province,Tamarindus indica was selected as the major species,and the artificial Tamarindus indica vegetation system was established.A lot of comparative analysis was carried out based on the data of factors such as crop growth,soil and atmosphere.The results showed that at Yuanmou dry and hot valley areas,choosing Tamarindus indica as the major species,the ecological effect of degraded slope land management was significant.The effects were the following four aspects: 1) the soil degradation was obviously controlled,the physical and chemical characters were improved,and the fertility was increased;2) the soil and water loss was reduced;3) the dry climate was adjusted to some extend,and the wind speed was decreased;4) aridity of plant was reduced,and the healthy growth could be achieved.
