第34届国际湖沼学大会专题1：碳循环和水库温室气体排放（Carbon cycling and greenhouse gas emissions in reservoirs）
第34届 国际湖沼学大会 专题 碳循环 水库温室 气体排放
2018/1/18
Reservoirs are environmental reactors that receive and process large amounts of carbon from their catchments and from the organic matter flooded during the impoundment process. Part of the ensuing emi...
Nitrogen, Phosphorus and Carbon Dynamics during Storms in a Glaciated Third-Order Watershed in the US Midwest
DOC nitrate phosphorus hydrology
2015/1/16
The characterization of the nutrients nitrogen, phosphorus and carbon (NPC) export to streams during storms is an integral part of understanding processes affecting water quality. Despite the fact tha...
Invasive Reed Canary Grass (Phalaris arundinacea) and Carbon Sequestration in a Wetland Complex
Carbon sequestration Residue quality Wetland complex Reed canary grass
2015/1/16
Terrestrial carbon sequestration is one of several proposed strategies to reduce the rate of carbon dioxide (CO2) accumulation in the atmosphere, but the impact of plant invasion on soil organic carbo...
Constrained microbial processing of allochthonous organic carbon in boreal lake sediments
boreal lake sediments Constrained microbial processing
2014/4/4
We investigated sediment bacterial metabolism in eight lakes with different inputs of allochthonous and
autochthonous organic carbon in south-central Sweden. Sediment bacterial production, mineraliza...
Chemistry and δ13C of Total Dissolved Carbon in Waters of Selected Springs nearby Lublin City
Chemistry Total Dissolved Carbon Lublin City
2009/10/27
The pH, 613c of total dissolved carbon and HCO;, Ca2*, Ca2+ + Mg2+ contents
in spring waters were investigated. Changes of these values were recorded
for 8 months of 1982 and 1983. The changes were ...
Studies of lake environments using stable isotope ratios of nitrogen (δ15N) and carbon (δ13C)
stable isotopes nitrogen carbon lake
2009/7/14
Increasing numbers of studies have recently used stable isotopes of nitrogen (δ15N) and carbon (δ13C) to clarify the source of nutrients in lake water and sediments, the structure and energy flow of f...
Simulation of the long-term carbon and nitrogen dynamics in Dutch forest soils under Scots pine
long-term carbon Dutch forest soils nitrogen dynamics Scots pine
2009/6/5
Dynamics of C and N in forest soils in the Nutrient Cycling and Soil Acidification Model (NUCSAM) are described by the transformation and decomposition of three organic matter compartments, litter, fe...
An argument for the use of two-layer SVAT schemes to simulate terrestrial carbon dioxide fluxes
surface temperatures soil respiration carbon dioxide fluxes
2009/6/5
An order-of-magnitude argument shows that the different surface temperatures of soil and sparse vegetation affect carbon assimilation and soil respiration significantly. However, regulation of assimi...
Dynamics of resource production and utilisation in two-component biosphere-human and terrestrial carbon systems
terrestrial carbon systems biosphere-human production-utilisation
2009/5/7
This paper analyses simple models for "production-utilisation" systems, reduced to two state variables for producers and utilisers, respectively. Two modes are distinguished: in "harvester" systems th...
The Thetford Project (1968–1976) was a keystone project for the newly established Institute of Hydrology. Its primary objective was to elucidate the processes underlying evaporation of transpired wate...
Implications of changing from grazed or semi-natural vegetation to forestry for carbon stores and fluxes in upland organo-mineral soils in the UK
semi-natural vegetation carbon stores upland organo-mineral soils
2009/5/6
In the UK, as organo-mineral soils are a significant store of soil organic carbon (SOC), they may become increasingly favoured for the expansion of upland forestry. It is important, therefore, to asse...
Fluvial organic carbon flux from an eroding peatland catchment, southern Pennines, UK
dissolved organic carbon particulate organic carbon organic carbon
2009/4/29
This study investigates for the first time the relative importance of dissolved organic carbon (DOC) and particulate organic carbon (POC) in the fluvial carbon flux from an actively eroding peatland c...
Modelling the effects of climate on long-term patterns of dissolved organic carbon concentrations in the surface waters of a boreal catchment
Dissolved organic carbon artificial neural networks
2009/4/29
Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, r...
Carbon dioxide measurements in the nocturnal boundary layer over Amazonian forest
dioxide measurements nocturnal boundary
2009/3/25
Measurements of carbon dioxide concentration, temperature and windspeed were made in the nocturnal boundary layer over a tropical forest near Manaus, Brazil using a tethered balloon system.
Examples of the effects of different averaging methods on carbon dioxide fluxes calculated using the eddy correlation method
Eddy covariance detrending
2009/3/24
Three hours of high frequency vertical windspeed and carbon dioxide concentration data recorded over tropical forest in Brazil are presented and discussed in relation to various detrending techniques ...
