URBAN LAND COVER AND SPATIAL VARIATION OBSERVATION USING ASTER AND MODIS SATELLITE IMAGE DATA
ASTER landscape metrics urban analysis land cover
2015/7/30
Land cover and land use changes associated with urbanization are important drivers of local geological, hydrological, ecological,
and climatic change. Quantification and monitoring of these changes ...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...
Wavelength-dependent spatial variation in the reflectance of ‘homogeneous’ ground calibration targets
Spectral reflection characteristic of remote sensing data and the ground measurements
2015/2/5
Remotely sensed data are most useful if calibrated to spectral reflectance of known features. One
simple method of calibration is regression of remote data on the reflectance of several ground
targe...
Spatial Variation and Tradeoffs in Species Interactions
Selection mosaic resource allocation tradeoff
2015/1/4
The geographic mosaic theory of coevolution predicts that spatial differences in species interactions result in a patchwork of evolutionary hot and cold spots across a landscape. We used horsenettle (...
Assessing the drivers of spatial variation in thermal forcing across a nearshore reef system and implications for coral bleaching
Assessing the drivers spatial variation thermal forcing across a nearshore reef system implications coral bleaching
2014/7/10
We examined the seasonal and spatial variability in the temperatures of nearshore reef waters over 19 months across Coral Bay at Ningaloo Reef, Western Australia. Local deviations in the mean daily te...
Effect of Different Nitrogen Fertilizer Types and Application Measures on Temporal and Spatial Variation of Soil Nitrate-Nitrogen at Cucumber Field
Solar Greenhouse Cucumber Nitrate-Nitrogen Nitrogen Retention
2013/3/8
Nitrate-nitrogen content of groundwater are ever-increasing in underneath vegetable growing areas, in this paper, based on field test of cucumber cultivated in Solar Greenhouse in North China, we stud...
Spatial variation of carbon dioxide fluxes in corn and soybean fields
Spatial Variation Transects Soil Organic Matter
2013/3/4
Spatial variation of soil carbon dioxide (CO2) flux during a growing season within corn and soybean canopies has not been quantified. These cropping systems are the most intense in the United States a...
Assessment of Spatial Variation of Groundwater Quality and Its Relationship With Land Use in Perth Metropolitan
Groundwater Quality Land use Perth
2013/3/19
To determine the effects of land use on groundwater quality in Western Australia, a quantitative analysis is carried out using groundwater quality data supplied by the Department of Water from over 50...
