Abstract

The invention discloses a measuring device and a measuring method for in-situ quick determination of primary productivity of lakes. The measuring device comprises a transmitting bottle, a shading bottle, a first bottle cap, a second bottle cap, a first dissolved oxygen sensor and a second dissolved oxygen sensor. The transmitting bottle is provided with a first opening, and the shading bottle is provided with a second opening. The first bottle cap is movably arranged on the transmitting bottle between a first opening position and a first closing position; the second bottle cap is movably arranged on the shading bottle between a second opening position and a second closing position. The first dissolved oxygen sensor is arranged on the transmitting bottle, and the second dissolved oxygen sensor is arranged on the shading bottle. The measuring device for in-situ quick determination of the primary productivity of the lakes has the advantages of short exposure time, high measuring accuracy, short measuring period, capability of achieving in-situ real-time observation and the like.

Description

technical field [0001] The invention relates to the field of environmental science, in particular to a measuring device for in-situ rapid determination of lake primary productivity and a measurement method for in-situ rapid determination of lake primary productivity. Background technique [0002] Biological productivity is the ability of organisms to produce (or accumulate) organic matter through assimilation, including primary productivity and secondary productivity. Primary Productivity (Primary Productivity) refers to the photosynthesis of green plants using sunlight, that is, sunlight + inorganic substances + H 2 O+CO 2 →Heat+O 2 + organic matter, putting inorganic carbon (CO 2 ) The ability to fix and transform into organic carbon (such as grape bran, starch, etc.). [0003] Primary productivity can be divided into gross primary productivity and net primary productivity. Total primary productivity refers to the rate of real photosynthesis, that is, the total amount...
