摘要
梭梭由树冠截留的降雨形成的树干径流将营养物质运送至根颈周围的土壤中，在根颈周围形成“肥岛”，增加该区域土壤的养分含量和水分含量，对自身生存环境产生正向反馈效应。
The stem runoff of Haloxylon ammodendron,which is rainfall captured by the crown of tree,carries nutrients down into soils around tree stem.This volume of water and nutrients can contribute to the development of “fertile island”,enhancing the water availability and nutrient content in the soil. It has effect of positive feedback on plant own environment .All these allow plants to be more resistant to arid enviroment. \ \
