【摘要】 从土壤水资源的角度对集雨绿化系统进行了初步的分析,建立了绿化系统模型。该系统以集雨、提高雨水利用效率为核心,运用种植区水量平衡方程初步解决了干旱半干旱区绿化缺水的问题。以中国科学院寒区旱区环境与工程所野外实验站为例,针对抗旱树种柽柳进行集雨绿化的问题进行实例分析。在可靠的理论和方法的基础上建立模拟模型,对造林具有一定的通用性、实用性和指导性,为干旱半干旱区进行集雨绿化提供了理论依据、系统模式及规划设计的实用性。更多还原

【Abstract】 The system of rainwater harvesting for affovestation(SRHA) are analyzed based on soil water resources. The system focused on rainwater harvesting and improvement of rainwater use efficiently. Model of SRHA was established using water balance equation of the planted area to solve water shortage for afforestation in the arid and semi-arid regions. Taking Tamarix ramosissima as an example, we explored main problems in the SRHA. The model has a reliable theoretical base and provides guidance for affroestation in the arid and semi-arid regions.更多还原
