Landscape structure,management and soil total nitrogen,total phosphorus in the densely populated rural landscapes of China's Yangtze Plain

In this study,we examined interactions between landscape structure,land management and soil total nitrogen(TN;top 30 cm) and total phosphorus(TP;top 30 cm) within the densely populated rural landscapes of the Yangtze Plain,based on an intensive field study in a regionally-representative sample cells in Yixing County.The rural landscapes were mapped at a high spatial resolution and classified to ecologically-distinct features(ecotopes) by the direct interpretation and field validation of features in 2002 IKONOS imagery using a standardized mapping procedure.Then the samples of soils and sediments were collected for analysis at random points within ecotope selected by a cluster distance weighting stratified sampling design.The five most extensive land use/land cover categories in the Yangtze Plain were paddy,aquaculture,built structures with impervious cover,rainfed annual cropland and fallow water,which occupied 82.9% of the total area,contained 82.6% of the total nitrogen and 80.8% of the total phosphorus stored in the region′s rural landscapes,respectively.Regional scaling analysis indicated that 85.24×103 km2 of Yangtze Plain rural landscapes sequestered 29.87 Tg of the total nitrogen and 19.79 Tg of the total phosphorus,of which 51% and 45% were in paddy land respectively(15.26 Tg of TN and 9.13 Tg of TP),covering 45.5% of the region′s total surface area(38.93×103 km2).Regional estimates of landscape class areas,soil total nitrogen and soil total phosphorus were made by upscaling data obtained from the sample cells by using a multivariate regional optimization procedure combined with bootstrapping and Monte Carlo uncertainty analysis.Then the role of land use/land cover in determining local total nitrogen and total phosphorus patterns and the regional consequences of these patterns were revealed across a densely populated rural region of China′s Yangtze Plain.This fine-scale approach to investigating land management practices and their impacts on total nitrogen,total phosphorus and other ecosystem properties offers significant advantages of accuracy rate over conventional lower-resolution(30-1000m) methods for land cover.
Thermodynamic stability maps for the La0.6Sr0.4Co0.2Fe0.8O3±δ–CO2–O2 system for application in solid oxide fuel cells

Abstract Thermodynamic and electrochemical predictions on the formation of secondary phases in CO2 containing atmosphere on the La0.6Sr0.4Co0.2Fe0.8O3±δ (LSCF-6428) surface have been carried out utilizing the CALculation of Phase Diagram (CALPHAD) approach. The effect of temperature, CO2 partial pressure, O2 partial pressure as well as the cathode composition on the formation of secondary phases have been investigated and correlated with the previous investigations in the literature. It is predicted that SrCO3 has the possibility to form on the surface as a result of CO2 exposure to the system. In addition, it is seen that LSCF-6428 experiences higher degradation due to the larger amount of segregated phases than LSM-20 at the same operating condition.
