Paper Abstract

The micrograph and the geographical information system(GIS) technology are combined, and applied into histiocytic anatomy. Through studying histiocytic changes of Cleistogenes squarrosa's vegetation organs, namely leaf and stem, the steppe plants' inherent mechanism of miniaturization is revealed. In the course of restoring succession, Cleistogenes squarrosa's anatomy of leaf and stem demonstrate the same variation trend in the three different sample plots: the longer the resume time is, the more, its cells which make up the organ are. According to opposite course, miniaturization has all taken place in the leaf and stem. However, there is difference in the miniaturization mechanism of the leaf and stem. (1) According to dissection structure of the blade, the reduction of organizing the figure of the mesophyll has caused miniaturization. (2) The miniaturization mechanism of the stem is the reduction of different organization's cell's figure of the stem.
