A simple biosphere model (version 2, SiB2) is an ecological model with high simulation accuracy, which can be used to simulate the dynamic change of the fluxes of water, heat and carbon. This paper simulated the dynamic change of the fluxes of energy and CO2 by SiB2 based on the observational data from June 20, 2005 to October 9, 2005 in Weishan experimental station. The results showed that SiB2 was...
The fraction of photosynthetically active radiation (FPAR) absorbed by global vegetation is a key state variable in most ecosystem productivity models and in global models of climate, hydrology, biogeochemistry, and ecology. Therefore, how accurately retrieve FPAR will directly influence the estimation of many models and requires special attention. In this paper, based on the ground truth data in...
Studying the services value of oasis ecosystems in arid middle reaches of the Heihe Oasis is significant for understanding the development and evolution, revealing the maintaining mechanism of oasis security, and promoting the resources and environment sustainable development of this area. Based on the data of landsat TM image in the middle of Heihe River Basin acquired in 2000 and 2006, land use...
Due to the non-renewablity of fossil fuels, the biomass energy has drawn more attention. However, owing to the large-scale dispersive distribution of biomass and lack of financial return to guarantee the sufficient feedstock of the centralized conversion facility, the development of the bioenergy is under slow progress in China. According to the previous research, there is a correlated coefficient...
