Description
Technical field
The invention belongs to ecological environment studying technological domains more particularly to a kind of open ozone concentration to increase simulation system
System.
Background technology
The aggravation of global industry and urbanization makes constituent of atomsphere be changed, and results in global warming, this is right
The sustainable development of environment for human survival and social economy constitutes a threat to, and causes extensive concern and the national governments of global scientist
Great attention.In order to evaluate, predict and cope with the consequence of Atmospheric composition variation, long-term effort has been done by scientific circles.Last century
Before the eighties, a large amount of research carries out in greenhouse, incubator or top-open type gas tank, but due to corresponding experimental condition such as temperature
The factors such as degree, wind speed, humidity, rainfall and natural conditions greatly differ from each other, especially the plant in experimental rig and insect, pathogeny every
From, the influence of Atmospheric composition and climatic change on ecosystem is predicted with acquired result of study from this simulated environment,
With more uncertainty；In addition, previous closed or semi-hermetic box facility growth inside space is limited, it is only capable of carrying out short
Phase tests (1-2), can not carry out O for years to the larger forest even ecosystem3Stifling experimental study.Therefore,
The system that some specific components in air can be increased under free air condition is developed, with as close possible to natural, ecological ring
Response and adaptation of the condition research ecosystem in border to whole world change, are very important.
Surface layer ozone (O3) it is mainly derived from the precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs)
The photochemical reaction of generation is a kind of secondary pollution having extremely strong toxic effect to land vehicles.In recent decades in air
The rapid raising of NOx and volatile organic matter, lead to surface layer O in global range3Concentration is just with annual 0.3%~2.0%
Speed continues to increase；Wherein, east China area surface layer O3The raising trend of concentration becomes apparent, especially densely populated
City and area, such as Surrounding Area of Beijing, be averaged summer day day (8h) O3Concentration is more than 100ppb, hourly average O3Concentration pole
Value is up to 300ppb or more.Therefore, earth's surface O3Pollution has been considered as region and global one of main Environmental Problems, at me
State, earth's surface O3Have become the primary air pollutants of most area summer.It is estimated that the increase of environment ozone concentration can be reduced
The storage in forests amount in China 7.7%.
Domestic and foreign scholars have successively developed and have increased CO under free air condition2The system of concentration specific components, but
It is the Atmospheric CO with constant concentration2It compares, O3When with apparent day and seasonal variety；In addition, O3It is the gas of strong oxidizing property
Body, therefore develop O3- FACE (Free Air gas Concentration Enrichment) platform has the challenge of bigger
Property.Currently, what is be completed in global range is used to study O3Influence the O of (10 years) for a long time on forest ecosystem3- FACE platforms
Only 2：The KROFEX platforms of the ASPEN platforms and Germany in the U.S..ASPEN platforms are from immature nursery stock (willow, birch and maple
Tree) start continuous CO2And O3It is 10 years stifling；KROFEX platforms are built upon existing mature forest dragon spruce (40 years) and beech (60
Year) mixed forest, study O3Influence to Forest Canopy carbon fixation.However, this 2 platforms only considered one or two kinds of air groups
Divide the influence to forest ecosystem, result of study is difficult multiple environmental factors caused by objective evaluation Present Global climate change
Such as CO2The common influences existed to forest ecosystem such as concentration is increased, heated up, arid, nitrogen deposition amount are aggravated and its weather are anti-
Feedback.At home, the O of the crops such as wheat and rice has been had3- FACE platforms, the O relative to crop3For-FACE platforms, forest
O3The area coverage bigger of-FACE platforms will also constantly extend with the growth of trees, build technology more in the vertical direction
For complexity；In addition, the O of crop3- FACE platforms only run a Growing season (about 3 months), and forest O every time3- FACE platforms are then
The continuous operation several years is needed, to the reliability requirement higher of equipment.
With the aggravation of human activity, global O3Concentration, CO2The environment such as concentration, heating, arid, the aggravation of nitrogen deposition amount are asked
Topic will maintain a very long time, O3With the compound service to the ecosystem especially forest ecosystem of other environmental factors
The influence of function (such as consolidate C, regulate the climate), will be the problem in science of national governments and scientist's common concern.O3-FACE
Platform is uniquely being capable of objective evaluation O3Forest Productivity is influenced with other environmental factors and to Global climate change feedback
Research means are necessarily widely used by domestic and international research institution in the research of forest ecosystem from now on.
