| 摘 要： | 针对目前研究中多关注某一单一植被类型的绿地水分利用和管理，较少实地研究植被组成更复杂的园林绿地复合生态系统的耗水规律的情况，该文通过对颐和园降雨、灌溉、土壤含水量和土壤基质势等指标的实地、原位、多点监测，利用分布式水量平衡基本原理，初步研究了乔草、灌草和纯草3种园林绿地系统的水分消耗规律。结果表明:乔草组合和纯草均表现为低耗水、高渗漏，灌草组合表现为高耗水、低渗漏；灌草组合和纯草比乔草组合具有较高的土体补水量。建议雨季应停止灌溉，防止水分渗漏，以临时性补灌为主，同时加强排水措施,尤其对于具有高渗漏特点的乔草和纯草系统；由于灌草具有高耗水性，应在设计节水型园林时减少使用。

| Abstract: | Water utilization and management in the urban landscape has become a focus of landscape engineers and gardeners.However,most of them are interested in water management of a single type of plant community rather than a complex plant ecosystem of urban landscape.The experiment was carried out to study water consumption of tree-grass,shrub-grass and pure grass plant ecosystems using the principle of distributed soil water balance by monitoring the rainfall,soil water content,irrigation and soil water matrix po... |
