Description
Technical field
The present invention relates to sabkha Study on Greenhouse Gas Emissions technical fields, in particular to Volatile Organohalides in research sabkha
The evaluating apparatus and evaluation method of release factor.
Background technique
It is the main object for destroying ozone layer though halide is simplest one kind compound in Volatile Organohalides
Matter.Halide mainly includes chloromethanes (CH3Cl), bromomethane (CH3) and iodomethane (CH Br3I), wherein CH3The photochemistry of I
Stability is lower, is hard to reach ozone stratosphere abundant, therefore ozone depletion potential is small, but CH3I is that system is accounted in marine environment
That controls status contains iodine compound, plays an important role to the iodine biochemical cycles in the whole world；CH3Cl and CH3Br is with higher photochemical
Stability and lower water soluble characteristic are learned, about 17% chlorine and 34% bromine are by CH in stratosphere3Cl and CH3Br is provided, right
Ozone layer generates in the gas destroyed, CH3Cl、CH3Br accounts for 13% and 15% respectively.Currently, global environmental change trend is polynary
Change, the ozone layer that " umbrella of life " is known as in atmosphere is in extremely fragile state, and halide rises in this course
Considerable effect.In addition, the halide in atmosphere also participates in photochemical reaction, and there is certain greenhouse effects and dirt
Toxic action is contaminated, therefore halide is otherwise known as greenhouse gases and has been to be concerned by more and more people.
Salt marsh is the Transient Areas for being in the big ecosystem in ocean and land two, regularly or irregularly extra large
Foreign tide floods, a kind of wetlands ecosystems with higher draft or low shrub vegetation's coverage.The table of research in recent years
Bright littoral zone sabkha is the important Spontaneous release source of halide, but also studies have found that sabkha is not only the source of halide,
With the variation of different spatial and temporal patterns, it is likely that can also be used as the remittance of halide.
There are apparent temporal-spatial heterogeneities for the discharge of sabkha halide.The discharge of sabkha halide can be with biology and ring
The variation of the border factor and show apparent diurnal variation, seasonal variations and Annual variations feature.The halogenated first of sabkha under normal circumstances
The burst size on alkane daytime is higher than night, and the discharge amount of Growing season is apparently higher than non-acoustic detection, not the discharge difference between the same year border
Also very big.For some sabkha in same place, the discharge amount of general middle high-order sabkha is higher than low level sabkha and Guang Tan.
The factor for influencing the discharge of sabkha halide is very more, and different geographical sabkha ecosystem halide is emitted on
Largely managed by the vegetation of sabkha (vegetation type, ground biomass, density etc.), illumination, temperature, wind speed, soil
Change property (soil moisture, organic matter, water content, salinity, pH, Eh, Br-、Cl-Deng), level of ground water, tidal action is (between gas production
Every, frequency etc.) and atmosphere in the factors such as methyl halide background concn influence.In many impact factors, illumination and
Temperature is the important driving force of halide production.Some researches show that the diurnal variation rule of salt marsh vegetation halide discharge at present
Rule has good consistency with temperature and photosynthetically active radiation (PAR), can indirectly influence salt by influencing the growth of vegetation
The generation of natural pond halide.
The data about sabkha halide in time and space extremely lack in the world, and especially the country is about sabkha
The research of halide is very limited.There are very long coastline and numerous river mouths, bay in China, there is the tide salt of extensive development
Natural pond has the advantage for carrying out correlative study.But sabkha ecosystem halide emission flux shortage is continuous, is
System, long-term, different geographical observation data, emission mechanism research is insufficient, urgently to the Study on Emission of sabkha halide
Reinforce.
But at present for the research of the discharge of sabkha percent of greenhouse gases by various actual environments and conditionality, therefore,
Using the source remittance feature and emission mechanism of sabkha halide under the conditions of experiment analog machine simulation Different climate to halide
Global emissions assessment and Reasonable Regulation And Control have highly important theory significance.Well understand halide isothermal chamber gas gas
Emission mechanism and influence factor for scientifically regulating and controlling its discharge by artificial policy and technical measures there is important practice to anticipate
Justice.
