中文摘要	本文应用光学显微镜和电子扫描显微镜的方法测量了生长在贵州省清镇市王家寨小流域内不同背景区（喀斯特与非喀斯特）11种植物的叶片解剖结构，比较了不同背景区整体植物以及各样地之间相同植物的叶片解剖结构与其delta~(13)C值的相关关系。研究结果表明，研究区内所有植物从非退化到退化过程中的叶片解剖结构与delta~(13)C值呈现显著的正相关关系，喀斯特背景区的竹叶椒和小叶鼠李，非喀斯特背景区的粉枝莓、油茶和构树的叶片解剖结构与delta~(13)C值也呈现显著的正相关关系，喀斯特背景区与非喀斯特背景区植物具有比较一致的变化趋势，而生长在两背景区的同种植物叶片解剖结构和delta~(13)C值均无显著性差异。这说明了在本研究小流域内，由于光、热、水、气等外部影响因素的一致性，不同背景区从非退化样地到退化样地的发展过程中，植物叶片的解剖形态特征为了适应环境的改变而产生了相同的响应趋势，这些响应变化均与植物叶片的delta~(13)C值具有正相关关系，尤其是石漠化样地上的植物叶片解剖形态特征以及其delta~(13)C值对生境条件的响应是最迅速和最敏感的。
英文摘要	The authors analyzed the anatomical structures of leaves for 11 plant species sampled from a karst catchment basin with different backgrounds （karst and non-karst）, which are located in Wangiiazhai, Qingzhen City of Guizhou Province, using the optical microscope and scanning electron microscope methods. Then, the correlations between the anatomical structures of plant leaves and their delta~(13)C values were compared in the following two ways; all plants as a whole in different background areas, and the same plant species from different plots. The results showed that there is a significant positive correlation between the anatomical structures of all plant leaves and their corresponding delta~(13)C values in the above areas in a successive series from nondegradation to degradation, and the same goes for the anatomical structures of Zanthoxylum planispinum, Rhamnus parvifolius with a karst background, Rubus biflorus, Camellia oleifera, Broussonetia papyrifera with a non-karst background and their corresponding delta~(13)C values, Moreover, there is a similar variation tendency for the correlation, and there is no significant difference for the anatomical structure of the same plant species with different backgrounds. Hence, it could be concluded that the anatomical features of plants have the same response tendency under the same external conditions including light, heat, water, gas, etc. , revealing that plants are adapting themselves to the environment during the degradation process, and their responses show a positive correlation with those delta~(13)C values. It is especially true for the anatomical structures and delta~(13)C values of plants in a karst rocky desertification area, which shows a quick and sensitive response to environment conditions,
