Effect of climate variables on the modeling of vegetation net primary productivity in karst areas
Green plants play an important role in matter and energy transformations and are key messengers in the carbon and energy cycle. Vegetation net primary productivity (NPP) reflects the capability of plants to convert solar energy into photosynthate (fixed carbon). It can be used as a direct indicator of current status and future trend of ecological processes affected by human activities and clima...
متن کاملNonlinear Variations of Net Primary Productivity and Its Relationship with Climate and Vegetation Phenology, China
Net primary productivity (NPP) is an important component of the terrestrial carbon cycle. In this study, NPP was estimated based on two models and Moderate Resolution Imaging Spaectroradiometer (MODIS) data. The spatiotemporal patterns of NPP and the correlations with climate factors and vegetation phenology were then analyzed. Our results showed that NPP derived from MODIS performed well in Ch...
متن کاملModelling Above ground net primary production of Sabalan rangelands using vegetation index and non-linear regression
Background and objectives: Alongside with the progresss in satellite sensors, their role on obtaining information and study of the environmental events and phenomena have become increasingly important. One of these precious data which is the basis for many planning and decision making in rangelands, is the above ground net primary production assements. The traditional method of estimating ANPP ...
متن کاملVegetation, plant biomass, and net primary productivity patterns in the Canadian Arctic
[1] We have developed maps of dominant vegetation types, plant functional types, percent vegetation cover, aboveground plant biomass, and above and belowground annual net primary productivity for Canada north of the northern limit of trees. The area mapped covers 2.5 million km including glaciers. Ice-free land covers 2.3 million km and represents 42% of all ice-free land in the Circumpolar Arc...
