In order to study the vertical movement of soil water, two loess profiles were sampled in Weinan on July 22, 2007 and March 22, 2008. Oxygen isotope compositions of soil water from the two profiles were measured to reveal information about soil water vertical transporting amount in unsaturated zone. The result show that soil water moved upwards and the vertical transporting amount is about 6.89mm...
Soil samples from three profiles were collected in the areas around Huangqihai by hand drill. The TDS value and chloride concentration of fifty soil water were determined and the basic principle of the calculation of mean chloride concentration, residual flux and chloride cumulative age was introduced. From TDS value and chloride concentration profiles, it is concluded the TDS distribution is almost...
With the development of sensor technology, remote sensing technology has entered a new stage, which can provide various remote sensing data quickly and timely. In some basic process of remote sensing image, such as change monitoring, fusion, and correction, superposition display becomes a direct and rapid method, which can evaluate the quality of the work. In order to solve the problem of the slowness...
