Unmanned aerial vehicle observation system for monitoring and researching carbon-water flux of regional scale ecosystem

Abstract

The invention provides an unmanned aerial vehicle observation system for monitoring and researching carbon-water flux of a regional scale ecosystem. The unmanned aerial vehicle observation system comprises a fixed-wing unmanned aerial vehicle, scientific observation parts and a ground control monitoring station; the scientific observation parts comprise a porous turbulence probe, an open-circuit water vapor and carbon dioxide gas analyzer, a gas analyzer electronic case, a GPS / INS combined positioning and attitude determination system, an airborne control computer and a power supply battery; the scientific observation parts are all installed on a platform of the fixed-wing unmanned aerial vehicle. According to the invention, observation task requirements of most ecological systems can be met; latent heat flux and carbon dioxide flux exchange capacity of a regional ecological system can be directly observed; the invention has the advantages of low observation cost, strong expansibility,flexible and portable observation and the like, is suitable for multiple aspects such as ecological system function and current situation investigation, ecological process research, ecological environment protection and the like of a large-range space area, and provides important data support for ecological environment research and protection.

Description

technical field [0001] The invention belongs to the technical field of ecological observation, and in particular relates to an unmanned aerial vehicle observation system for monitoring and researching the carbon and water flux of an ecological system on a regional scale. Background technique [0002] The observation of the ecosystem is a basic method for the investigation and evaluation of the current status of the ecological environment, and it is also one of the core scientific issues in the field of ecological research. At present, the observation of ecosystem function is to conduct long-term observation of ecosystem through ecological observation sites. However, the spatial area covered by the observatory is extremely limited, and it is difficult to obtain accurate information on regional ecosystem function elements. The method of satellite remote sensing inversion can obtain the quantitative information of the material and energy exchange elements of the ecosystem on a...
