Description
Technical field
The present invention relates to a kind of solid carbon method and carbon credit quantitative detecting method.
Background technology
Global warming issue current be one of topmost problem in earth environmental protection, and wherein the most outstanding environmental phenomenon is exactly greenhouse effect.
So-called greenhouse effect are mainly the effects due to greenhouse gases, be in specific words, greenhouse gases can absorb the solar radiation of ground return by day, and again launch earthward the radiant energy of holding back daytime night, thereby make the earth cannot normally carry out the circulation of heat as a greenhouse, cannot be to the unnecessary heat of external radiation, and then cause earth surface temperature rise.
Greenhouse gases comprise steam, carbonic acid gas, methane, nitrous oxide and ozone etc.There is no greenhouse gases, the earth does not just have enough warm activities that sustains life, so greenhouse gases are important parts in atmosphere.
By 2011, the content of atmosphere percent of greenhouse gases-carbonic acid gas reached 391ppm(1ppm and has been 1,000,000/), the content of the nitrous oxide content that reached 324ppd (1ppb is part per billion), methane reached 1803ppb.Than whole high by 40%, 20%, 150% before industrialization.Some greenhouse gases are that natural environment produces, and the overwhelming majority is wherein the result of mankind's activity.In air, most of carbonic acid gas is caused by mankind's activity, the burning of for example fossil fuel, running of cement factory etc.
The concentration of some greenhouse gases, along with the time is in continuous increase, now unanimously thinks that the increase of greenhouse gas concentration can cause global warming.
Global warming and then can cause again a series of environmental problem, for example: ice shelf disappears, sea level rise, the change of rainfall pattern and the strength increase of extreme weather and take place frequently etc.
These natural calamities have caused serious economic loss, and in order to make great efforts to reduce these losses, many countries are exploring and reducing the method for air when percent of greenhouse gases.As the main contributions person carbonic acid gas of greenhouse gases, nowadays become global focus in the nature of things.Want to alleviate greenhouse effect, just must must reduce the central carbon dioxide content of atmosphere.
Nowadays there are two kinds of main methods to process the carbonic acid gas in atmosphere.
First method is from all, reduces the discharge of carbonic acid gas.Such as: the burning of restriction fossil fuel.
Another kind method is to make great efforts to absorb or remove the carbonic acid gas in atmosphere.We are called the mechanism that removes carbon from atmosphere " carbon remittance ".
" forest " is that carbon converges and talks about the highest one of frequency in type.The application of trees absorbing carbon dioxide has been studied widely and has been theorized, as patent No. Chinese invention patent " a kind of greenery patches, garden carbon sink detection system based on automatic sampling analysis " that is CN201310060276.4 etc.
Although but carbonic acid gas can absorb by trees, this form could not well be applied, main cause is that Forestry Carbon Mitigation only can store a period of time, and carbonic acid gas can not be sealed up by forest is permanent.Because the burning of trees or rotten situation, carbon will be discharged in atmosphere again; And Forests carbon is consuming time longer, cost is higher is also subject matter.
So sight has been turned to another very important carbon remittance carrier---ocean by we.
The carbon of being sealed up for safekeeping in carbon converges is the basis that obtains " carbon credit ".Discharge transaction plan is used cap-and-trade arrangement conventionally, and government organs arrange limit and provide the discharge permit that represents a certain amount of pollutant emission right for the discharge capacity of license.But how to confirm carbon credit, is converted into carbon credit after needing carbon emission quantitatively to detect, this just concludes the business and has brought the difficulty of essence to carbon credit.Make government be difficult to real fair and reasonable enforcement and assessment.

Water body refers to whole breeding water body.Be the culture zone of whole shellfish, the whole region from seawater surface to seabed.Also comprised that people is other microorganism, algae, fish and the excreta thereof etc. in bait and the water body of knocking down in water.
Marine shellfish, in breeding process, can utilize carbon in seawater to form the body, and main component is calcium carbonate, can be expressed as with chemical equation:
The shellfish body is fixed carbon in seawater in process of growth, and the carbonic acid gas of absorption is converted into calcium carbonate and is sealed up for safekeeping to form hard shell in body of shellfish.
In the breeding process of shellfish biology, by reducing the method for input of bait, so that the ratio of the C/N of water body, C/P all reaches more than 2.
Described miniature organism comprises the unicellular organism of all kinds of autotrophys, heterotrophism, eucaryon, protokaryon and there is no cell structure but have the viroplankton/phage of ecological functions.Be less than the nanoplankton of 20 μ m and/or the individual hekistoplankton that is less than 2 μ m as good taking individuality.
The explanation as an example of mussel culture example:
In mussel culture process, it is 2% that mussel is controlled at 20 ± 3 DEG C, salinity control in the temperature in seedling stage, and seedling rope adopts atropurpureus coir rope.Before putting in a suitable place to breed, mussel seedling is carried out to the domestication of culture zone water temperature, salinity, current speed.Be conducive to improve the adhesive rate of mussel seedling.Adopt specific seedling rope (atropurpureus coir rope) and wrap seedling processing and can effectively improve the survival rate of mussel in the time putting in a suitable place to breed putting mussel in a suitable place to breed.By reducing the method for input of bait, so that the ratio of the C/N of water body, C/P all reaches 10, make seedling water be micro-green.
In mussel culture, can take in the seawater that contains dissolved carbon dioxide, these carbonic acid gas transform in mussel body, and add other elements to become calcium carbonate, and it is the main component of mussel shell.In other words, mussel is that calcium carbonate is to form hard shell the carbon dioxide conversion of taking in.
The main component of mussel shell is calcium carbonate, and calcium carbonate can stably be present in breeding water body.Therefore the carbonic acid gas that, mussel absorbs can be stored in shell effectively.The carbon being stored in like this in shell just can remove by results shellfish from breeding water body, and the carbon that has directly formed breeding water body converges.
Shellfish culture has consumed the carbonic acid gas dissolving in seawater, having reduced the gas concentration lwevel in breeding water body declines the partial pressure of carbon dioxide in seawater, airborne carbonic acid gas is more easily dissolved in ocean, in other words, these shells have increased the absorbing capacity of water body to carbonic acid gas, and the carbon that has formed breeding water body converges.
A large amount of cultivation of mussel have produced a large amount of carbon containing shells, its calcium carbonate content is more than 95%, calcium carbonate is highly stable under field conditions (factors), is not easy carbonic acid gas to be discharged back in atmosphere easily, therefore the permanent carbonic acid gas that removes from atmosphere effectively such as mussel again.
Autotroph in mussel culture water body, as algae etc.And the cultivation bait of mussel and the excreta of mussel etc. obviously raise the content of the dissolved organic carbon in breeding water body, dissolved organic carbon can pass through biochemical reaction, then gets back in atmosphere with the form of carbonic acid gas.
This method is converted into inertia dissolved organic carbon by the ecological process of miniature organism by a large amount of dissolved organic carbons, makes it no longer to enter biochemical cycles, no longer discharges back in atmosphere with the form of carbonic acid gas.To guarantee that the carbon that mussel growth produces converges effectively.
In " Kyoto Protocol of UNFCCC ", estimate that industrialized country's carbon dioxide discharge-reduction cost is 150～600 beautiful yuan/ton, to RMB exchange rate (1 dollar=6.08 yuans), amount to 912.5～3648.0 yuan/ton with reference to recent dollar; The same period, China's cost of forestation was 250.0 yuan/t.Consider, can estimate approximately 600.0 yuan/ton of China unit's carbon emission reduction Financial cost.Can estimate accordingly the magnitude of value that shellfish and algae carbon converge: the carbon remittance magnitude of value=carbon sink × unit carbon emission reduction Financial cost.
According to the data of " China Fisheries yearbook ", the aquaculture gross yield of China in 2010 is 1.25 × 10
10ton, wherein the output of shellfish is 1.11 × 10
9ton.Because filter-feeding shellfish shell phosphorus content is 11.44%～12.01%.The carbon removing from ocean by the results of cultivated shellfish has 1.29 × 10
8ton, is equivalent to 3.84 × 10
8ton carbonic acid gas.Amount to into RMB, within 2010, China is 22.96 hundred million yuan by the available carbon remittance of cultivated shellfish income.
