中文摘要：

本文将显微照相和地理信息系统的理论与方法相结合,应用于组织解剖学中。通过对内蒙古锡林郭勒盟典型草原不同退化研究样地双齿葱(A llium bidentatum)营养器官叶组织细胞变化的研究,揭示出草原植物小型化的内在机制。随着群落恢复演替的进程,3个群落样地中的双齿葱植株叶的解剖结构呈现出的变化趋势:(1)恢复时间越长,其组成器官的细胞数目越多;(2)从叶片的解剖结构来看,叶组织数目的减少导致了小型化。

英文摘要：

This paper combines the theory and method of microscopic photography with geographic information system,and used them in anatomy organizations.Through the research of changing in the nutrition organ of A llium bidentatum such as leaf organ cells on different kinds of typical grassland with degradation in Xilin Gol town of Inner Mongolia,revealed the internal mechanism of the prairie plant miniaturization.As in the course of community restoring succession,the dissection structure of A llium bidentatum leaf i...
