摘要
元谋干热河谷典型区具有北热带温度条件和长达半年以上的干季时间 ,植被生态系统具有破坏容易恢复难的特点。经广泛的资源调查 ,选择罗望子作为治理退化坡地的先锋树种进行人工栽培。结果表明 :罗望子不仅是一种经济林木 ,而且具有水土保持、改良土壤、调节气候等生态效益功能。
The representative area of dry-hot valley of Yuanmom has a temperature conditi on of the northern tropical zone and a long season of more than half a year. The characteristic of the ecosystem is easy to be ruined and difficult to be resume d. By widely researching of resources,choseTamarindus indicaas a superior pioneer species making man-made cultivation to harness degraded slope land.
