摘    要:生态水文实验与监测装置的研制对生态水文过程模拟、参数获取与结果验证具有重要意义。在合理创新基础上,构建了便携式生态水文实验与监测系统(Eco-monitors)。Eco-monitors由植被覆盖度动态获取系统(VC-DAS)、便携式光合作用测量系统、便携式人工模拟降雨装置、土壤水运动监测装置及径流/土壤水采样装置等功能模块组成。Eco-monitors及其各功能模块的集成与设计重点突出便携性特点,既包括现有产品如便携式光合作用测量系统、土壤水运动监测装置及径流/土壤水采样装置;也包括自主创新部分如植被覆盖度动态获取系统(VC-DAS)采用摄像头方案代替传统的数码相机,便携式人工模拟降雨装置采用人工压力泵,克服了蓄电池或电力传动装置供电要求高且难以携带的限制。Eco-monitors在多项研究项目中得到了成功应用。

关 键 词:生态水文过程  实验与监测  植被覆盖度  植物生理过程  人工模拟降雨  土壤水

Abstract:The development of the devices for the eco-hydrological experiment and monitoring has key importance for the simulation of eco-hydrological processes,data collection,and verification of the modeling results.A portable eco-hydrological experiment and monitoring system called Eco-monitors was constructed upon some reasonable innovations.The Eco-monitors system consists of several key functional components including the Vegetation Coverage Dynamic Acquisition System(VC-DAS),the Portable Photosynthesis Measurement System(LI-6400),the Portable Artificial Rainfall System,the Soil Water Movement Monitoring devices,and the Runoff / Soil Water Sampling Devices.The integration and design of each of the components in the Eco-monitors system had prominently portable characteristic,including the portable products such as LI-6400,HOBO,and Runoff / Soil Water Sampling Devices,and the independent innovations such that webcam is applied in the VC-DAS instead of the traditional digital camera to improve the efficiency of field work for the acquirement of real-time bulk vegetation coverage information and that artificial pressure pump is applied in the Portable Artificial Rainfall System to overcome the restrictions of high power requirement and difficulty for carrying of the accumulator and electric actuator.The Eco-monitors system has been put into practice successfully in various research projects.
Keywords:Eco-hydrological processes  experiment and monitoring  vegetation coverage  plant physiological processes  artificial rainfall  soil water
