摘要:

基于民勤荒漠植物非称量蒸渗仪试验系统研发过程,对民勤不同监测时段的非称量蒸渗仪结构设置、试验监测及其监测结果应用情况进行对比分析。结果表明:民勤非称量蒸渗仪试验研究起步较早,先后经历了5代非称量蒸渗仪试验系统的研发改造过程。第1、2、3代非称量蒸渗仪试验系统的建立,使民勤荒漠植物蒸渗试验得到逐步发展与完善;第4代荒漠植物非称量蒸渗仪试验系统增设了渗漏监测,模拟了荒漠植物真实的补水状态,设计出不同地下水恒位补偿式蒸渗仪和渗漏型蒸渗仪,实现了地下补水与地面灌水试验的同步监测;第5代荒漠植物非称量蒸渗仪试验系统通过扩容改造,实现了荒漠植物林木与林分尺度蒸渗试验的同步监测,并基于电子传感技术实现蒸渗监测自动化管理,为尺度水平荒漠植物蒸散耗水研究及其监测数据的网络资源共享提供保障。

Abstract:

Based on the development process of the test system of non-weighing lysimeter for desert plants in Minqin, the structural design, test monitoring and resulting application of non-weighing lysimeter at different monitoring stages were compared and analyzed. The results showed that the experimental research of non-weighing lysimeter in Minqin started earlier, and had experienced the research and development for five generations. The building of the first, second and third generation of the test system of non-weighing lysimeter gradually developed and improved the evapotranspiration test of desert plants in Minqin. The 4th generation test system of non-weighing lysimeter was designed with constant water level compensation lysimeter and leakage lysimeter by adding leakage monitoring and simulating the real hydrating state for desert plants in the test area, realizing the synchronous monitoring of tests of groundwater remediation and surface irrigation. The 5th generation test system of non-weighing lysimeter realized the desert plant evapotranspiration test synchronous monitoring for unity and population scales with expansion and transformation for lysimeter structure, and achieved automatic management of evapotranspiration monitoring based on the electronic sensing technology management, which guaranteed the study of the scale level desert plant transpiration water consumption and the network resource sharing of monitoring.

Key words: non-weighing lysimeter, rehydrating at constant water level, leaking, transpiration water consumption, Minqin
