Based on the observed data from 51 meteorological stations during the period from 1958 to 2012 in Xinjiang, China, we investigated the complexity of temperature dynamics from the temporal and spatial perspectives by using a comprehensive approach including the correlation dimension (CD), classical statistics, and geostatistics. The main conclusions are as follows (1) The integer CD values indic...

Dasymmetric mapping is an areal interpolation method which transfer data from the source zones to the target zones. Although many dasymmetric mapping methods have been developed, few research have been conducted from accuracy assessment perspective. This paper reviews the methods which can be used to serve this purpose. Three methods were experimented: (1) cartographic mapping, (2) summary stat...

A method for 3D modeling and interpretation of log properties from complex seismic attributes (obtained from 3D post stack seismic data) is developed by integrating Principal Component Analysis and Local Linear Modeling. Complex seismic attributes have non-linear relationships with petrophysical properties of rocks. These complicated relationships can be approximated using statistical methods. ...

The carbon stock (C Stock) is a key soil attribute, especially in areas under degradation. objective of this study was to map the C Stock and other physical chemical attributes on surface micro-watershed located Gilbués Desertification Nucleus calibrate pedometric functions them, applying spectra obtained by Diffuse Reflectance Spectroscopy (DRS) near-infrared (NIR) region. This developed Pirip...

Temporal and Spatial Modeling of Groundwater Level in Bushehr Plain using Artificial Intelligence Geostatistics

The three-dimensional (3-D) modeling of glacial sediments often requires the use of lithologic logs from public water well data. The interpretation of such data is difficult because data collection methods are not standardized among contributing drillers, and the sequence of recorded lithologies contains both stratigraphic and facies-scale information. Geostatistics coupled with interpretation ...

Mining subsided lakes are major obstacles for ecological restoration and resource reuse in mining regions. Transforming mining subsided lakes into artificial wetlands is an ecological restoration approach that has been attempted in China in recent years, but a value assessment of the approach still needs systematic research. This paper considers Jiuli Lake wetland, an artificial wetland derived...

introduction the knowledge about spatial variability of precipitation is a key issue for regionalization in hydro-climatic studies. measurements of meteorological parameters by the traditional methods require a dense rain gauge network. but, due to the topography and cost problems, it is not possible to create such a network in practice. in these cases the spatial distribution pattern of precip...
