摘　　要：园林植物传统灌溉方式依靠人工经验、控制器定时灌溉,极大浪费水资源。为此,以植物生存极限需水量为依据设计了精准灌溉自动控制系统。系统主要由土壤水分传感器网络、灌溉监测控制器、远程监控计算机和电磁阀组成。该系统可以按照植物生存阈值要求对植物进行精准灌溉,并成功应用于国家重点工程"北京民族大道综合改造工程"。The traditional irrigation for gardens and parks mainly depended on experiences or timer, which wasted water source seriously. Precise irrigation automatic control system designed by plant＇s survival-limit and it was composed of soil moisture sensors, irrigation monitors, remote monitoring computers and solenoid valve controllers. The experiment results indicated that this system could save water source more efficiently compared with traditional irrigation systems, and successively applied in national key project： Comprehension Reformation Project of Beijing Minzu Avenue.
