The Influence of Climate and Landscape on Hydrological Processes, Vegetation Dynamics, Biogeochemistry and the Transfer of Effective Energy and Mass to the Critical Zone

摘要: The Critical Zone (CZ) is the surficial layer of planet that sustains life on Earth and extends from base weathered bedrock to top vegetation canopy. Its structure influences water fluxes, biogeochemistry vegetation. In this dissertation, I explore relationships between climate, dynamics, biogeochemistry, effective energy mass transfer fluxes (EEMT) in a semi-arid critical zone. This research was carried out upper Jemez River Basin northern New Mexico across gradients climate elevation. main objectives were (i) quantify relations among inputs (EEMT), hydrological biogeochemical processes within CZ, (ii) determine dynamics high elevation mountain catchments with different terrain aspect solar radiation, (iii) study temporal variability its influence CZ availability, forest productivity fluxes. key findings include significant correlations EEMT, transit times (WTT) mineral weathering products around Redondo Peak. Significant observed dissolved (Na+ DIC) maximum EEMT. Similarly, concentrations measured at springs significantly correlated EEMT; aspect strongly controls energy, distribution, ecosystems draining aspects predominantly north facing catchment, when compared other two eastern catchments, receives less exhibits cover smaller biomass, has more surface runoff consumption. Furthermore, catchment showed NDVI values shorter growing season length as consequence 3H .
