Description
Technical Field
The invention relates to the field of design and manufacture of ecological observation large-scale experimental equipment, in particular to a physicochemical effect measurement system for measuring plant respiration in forests.

Global climate warming is currently the most interesting climate phenomenon for human beings, and the direct action of the global climate warming can lead to glacier ablation and sea level elevation, so that many ocean countries and island countries are submerged, and the existence of human beings is seriously threatened. This phenomenon also causes frequent extreme weather, violates normal weather rules, and causes damage to the production and life of people, which cannot be predicted in advance.
Global warming is closely related to respiration of plants on earth, because plants are the lungs of earth and green plants absorb CO under the action of sunlight 2 Gas release O 2 And CO 2 It is the main cause of global warming, and on the whole world, the green students developed respective field ecological observation systems to measure the effect of global warming when the respiration of local vegetation, in this regard, as the global climate research center relying on the national laboratory of oak-greenbelt in Miss, U.S. established a sunlight glass house with various plants grown therein, relatively short, not exceedingGlass houses of 5 meters or less were used to study respiration of grassland plants.
In measuring respiration of plants, the leaf to be measured is put under the tree with a bow and then the respiration of the leaf is measured on the ground with a special device, and the current global measurement technology has significant drawbacks based on this level due to the advancement of research in this aspect of the united states:
1. because of the limitations of the united states in building large scientific research facilities, they are currently unable to build such large field measurement systems because the average height of wild trees is below 20m and the building is under the complex environment of hillside. The similar building in the United states can only be built on flat ground, the height is not more than 3-5m, the trees are transplanted and do not naturally grow in the field, and therefore experimental data of the similar building cannot truly reflect the reality of natural environment.
2. The bow and crossbow is adopted to shoot leaves for detection, although the leaves can continue to breathe in a short time, the respiration effect of the leaves is strictly different from that of the leaves in a natural state, but no special method exists at home and abroad at present because the respiration data of the leaves of the plants at high places is wanted to be measured when the leaves are in artificial forests.
In addition, a scheme of measuring by adopting a tower crane is proposed, but the tower crane is built on a mountain body to bear the action of cross wind, the tower crane is not easy to bear the action of severe cross wind on the mountain body and is easy to turn over, when the tower crane is used, the combined action of a person on the tower crane for opening the tower crane and a flag-driving hand on the ground is required to be completed, but in a tree forest, the tree leaves block the flag-driving hand, the flag-driving hand cannot be seen by the person on the tower crane, and thus the operation cannot be completed, so that the scheme of measuring by adopting the tower crane is not feasible.
