Description
Technical field
The present invention relates to a kind of environment parameter measuring instrument, especially relate to a kind of forest microcosmic carbon remittance metering assimilation box parameter measurement instrument.
Background technology
The global disasters such as Against Global Climate Changes becomes increasingly conspicuous, and it will cause ecosystem degradation, disaster takes place frequently, the degree of depth touches grain, water resource, the energy, ecology and public health security, directly threatens the survival and development of the mankind.With legal form, Kyoto Protocol requires that industrialized country controls and reduces by six kinds of greenhouse gases, wherein mainly CO
2discharge, therefore while economic development, reduce the CO that brings of economic growth
2discharge capacity, exploring low carbon development road has become whole world common recognition.Forest, as the main body of terrestrial ecosystems, has the characteristic that can repeat to regenerate, and have the double action that carbon source and carbon converge, especially ability to pool carbon, can not only greatly alleviate climate warming trend, and effectively can offset CO
2discharge, promotes the balance of carbon in earth ecology system.CO is offset by Forestry Carbon Mitigation
2discharge has become the important content of international weather pact, is subject to the extensive concern of countries in the world government and scientist.In recent years, China's air quality is degenerated very fast, and only haze index is just the trend of expanded range and duration extension, has become the serious problem of society today causing the healthy fear of the common people.Improve the important process target that air quality becomes governments at all levels of China, carry out impose carbon tax system and carry out carbon transaction business also imperative.
Forestry Carbon Mitigation refers to that forest plants absorb the CO in air
2and be fixed in vegetation or soil, thus reduce this gas concentration in an atmosphere.Carbon remittance metering is then the evaluation to Forestry Carbon Mitigation ability, both at home and abroad about the metering method of Forestry Carbon Mitigation mainly contains accumulation method, biomass method and Biomass inventories method.Because this type of Method And Principle is simple, directly perceived, be the method extensively taked at present, but the just static estimation of these class methods, can not the development trend of dynamic reflection Forestry Carbon Mitigation, and mostly choose conversion factor by rule of thumb, this just directly affects the reliability estimating result.Therefore be necessary to find a kind of generally acknowledged Forestry Carbon Mitigation metering method, due to box method, there is accurate measurement, quantitative examination and be convenient to the advantages such as enforcement, box method is widely used in quantitative test gas flux, but the method also existing some shortcomings:
(1) choosing of research object has certain representativeness, comprises the species of selection, quantity and age.
(2) case internal and external environment differs greatly, and is mainly manifested in the environmental parameters such as humiture.
(3) uncertainty of carbon remittance computation model.
(4) be difficult to realize automatic, continuous coverage.
These shortcomings hinder the application and popularization that box method measures at Forestry Carbon Mitigation, the research of Forestry Carbon Mitigation rarely has report to utilize the method to estimate, assimilation box device for plant, plant organ and population measure there is not yet commercially produced product, and Chinese scholars mostly makes box system by oneself to carry out such research.Therefore, be necessary to explore a kind of error in dipping little, can the assimilation box device of continuous coverage, thus explore the metering method of individual plants carbon remittance amount, for the metering method model of the carbon remittance amount setting up this type of forest of a certain area provides Data support.
At present, measuring system needed for the carbon transaction of China is still in the starting stage, no matter adopt the computing method of which kind of existing carbon remittance amount based on macroscopical biodemography method, the result obtained all is difficult to ensure the accurate and unified of value, thus makes magnitude tracing become urgent need to solve the problem.Therefore, from microcosmic and medium measure, mechanism converged to the carbon of forest and study, thus explore the path of tracing to the source of the value of key parameter, for realizing the accurate-metering of macroscopical carbon remittance amount and setting up China's carbon and converge measuring system and provide technical support.
