中文摘要	在综述了我国半干旱地区沙质草地沙漠化过程中植被演替研究现状，提出了目前沙地植被演替研究中存在的主要问题和今后的研究工作。指出，①沙地植被演替的最大特点就是沙质地表基质的流动性和风沙活动伴随着植被演替的各阶段，研究中应考虑近地表风沙流的影响；②在干扰对生态系统影响越来越大的今天，沙地植被的演替序列往往出现一些随机性和不规则性，应加强对沙地植被演替序列的非线性和演替顶极的多元性、多样性的研究；③应继续从生理生态、种群生态、群落生态以及生态系统生态等不同水平层面上深入研究演替过程中植物种的替代机制，还应加强沙地土壤种子库与地上植被动态耦合、种子岛效应等的研究，以及沙地植被演替趋势和速率等的预测。
英文摘要	In this paper, the main problems existed in the studies of sandy land vegetation succession in the process of desertification and their future work were brought forward, based on the present researches in China semiarid regions. Firstly, sand-blown landform character should be considered, because the most evident character of sandy land vegetation succession was the sandy material shifting and sand-blown motion accompanying with each stage of vegetation succession. Secondly, the study of the nonlinearity of sandy land vegetation succession sequence and the diversity of succession climax should be intensified, because more and more heavy disturbance on ecosystem today made the sandy land vegetation succession sequence present some randomicity and irregularity. Lastly, the specific substitution mechanisms of plants in the process of succession should be lucubrated continually on the levels of physiological ecology, population ecology, synecology, and ecosystem ecology, and the study of the linking between the seed bank of sandy land soil and the dynamics of overground vegetation, as well as the prediction of the succession trend of sandy land vegetation should be further strengthened.
