Abstract

The monitoring of desertification requires important biological and physical methods. In this chapter, diagnostic methods for regional desertification of the Loess Plateau will be introduced using water balance and water-use efficiency obtained by actual field observation and remote sensing techniques. A wetness index using a numerical simulation soil model (see Chap. 2) and meteorological data from 43 observatories was developed for diagnostic methods at the macro scale (across the Loess Plateau). Potential distribution of vegetation cover in the plateau was explored by comparing the distribution as determined by the wetness index with the present-day vegetation cover from satellite imagery.

The index, using a numerical simulation model and remote sensing technology, was developed to estimate the surface wetness of each land surface type at a local scale. The index corresponded with actual seasonal variation of moisture availability over an area of varied land-cover types. This method could be used as aridity and/or drought indices.
