Remote sensing analysis of croplands, woody plant encroachment and carbon fluxes of woody savanna
Wang, Jie (2017-05-12)Since 1990s, much attention has been paid to Land use/land cover change (LULCC) studies because it is an important component of global change. The vegetation change is a critical factor of land cover changes, which interacts ... -
RESPONSES OF COMMUNITY STRUCTURE AND ECOSYSTEM FUNCTIONING TO CLIMATE CHANGE – META-ANALYSIS, MODELING, EXPERIMENTAL STUDY AND DATA-MODEL FUSION
shi, zheng (2015)Observations, experimental studies and modeling endeavors all show that global climate change, mainly increased surface air temperature and associated change in precipitation regime, has caused impacts on plant community ... -
Responses of Terrestrial Biogeochemical Cycles to Global Change – Syntheses and Data-Model Integration
Liang, Junyi (2016-12)Global observations and model simulations show that atmospheric carbon dioxide (CO2) concentrations and surface temperatures have been and will keep increasing. These environmental changes have significant influences on ... -
SATELLITE-BASED CHARACTERIZATION OF CROP TYPE AND PRODUCTIVITY OF AGROECOSYSTEMS: CASE STUDIES IN NORTHEAST CHINA, SOUTHERN AFRICA, AND CONTERMINOUS USA
Jin, Cui (2016-05-13)Agroecosystem, or agricultural ecosystems, is the important anthropogenic ecosystem to meet the human demand for food, fiber, and feed, and it covers approximately 40-50% of the earth’s land surface. Accurate estimates of ... -
THE USE OF REMOTE SENSING AND EDDY COVARIANCE TECHNOLOGIES TO CHARACTERIZE CROPLAND, DROUGHT AND LAND MANAGEMENTS AND THEIR IMPACTS ON ECOSYSTEM DYNAMICS
Zhou, Yuting (2017-05-12)With the increasing population, human needs more food, fresh water, and other ecosystem services, which burdens the agricultural and natural ecosystems. Under the background of climate change, meeting these human needs ...
