Embodiment Construction

[0026] See figure 1 , a portable eco-hydrological experiment and monitoring system (Eco-monitors) of the present invention consists of the vegetation coverage dynamic acquisition device and system (VC-DAD and VC-DAS), a portable photosynthesis measurement system (LI-6400), a portable It is composed of functional modules such as artificial simulated rainfall device (CSRS), soil water movement monitoring device (HOBO) and runoff / soil water sampling device. Each component is not only an independent functional module, but also an organic whole connected with each other.

[0027] See Figure 2a , Figure 2b, the hardware device (VC-DAD) of the vegetation coverage dynamic acquisition system and the vegetation coverage dynamic acquisition system software (VC-DAS) are efficiently coupled and connected, and work together to support field quadrat photo shooting and vegetation coverage information real-time dynamics extract. The vegetation coverage dynamic acquisition device consists ...

Abstract

A portable eco-hydrological experiment and monitoring system integrates five main functional modules: (1) a dynamic acquisition device and system for vegetation coverage degree realizes photo collection of a quadrat and real-time, dynamic, batch acquisition of vegetation coverage degree information; (2) a portable photosynthesis measurement system realizes measurement of a plurality of plant physiological indexes, such as plant photosynthesis, plant and soil respiration, transpiration, and fluorescence; (3) a portable artificial rainfall simulation device realizes variable raininess simulation on a quadrat of 1 m<2>; (4) a soil water movement monitoring device achieves real-time dynamic monitoring of soil volumetric water content; nd (5) a runoff / soil water sampling device realizes slope runoff and soil water sample collection. The five functional modules are independent and form an interrelated organic whole; and the system is applicable to development of a large number of simulation experiments and monitoring work in the field, and plays the role of technical support for the research on eco-hydrological process.

Description

technical field [0001] The present invention is a portable eco-hydrological experiment and monitoring system (referred to as Eco-monitors) in the field of geosciences, which is used for artificially simulating rainfall, slope runoff and soil water dynamic monitoring and monitoring in the field. Sample collection, vegetation coverage information extraction and vegetation physiological process monitoring serve a series of research on ecological hydrological processes such as rainfall-runoff, soil water movement, soil erosion, nutrient migration, vegetation physiological changes, etc., and belong to the field of physical geographic system technology. Background technique [0002] Ecohydrology is a science that studies the hydrological mechanism of ecological pattern and ecological process change. The ecohydrological process refers to the functional relationship between the hydrological process and the biodynamic process. The ecohydrological process at different time and space s...
