沙生植物的生长对沙地基质流动性的响应

Response of Growth of Psammophyte on Mobility of Matrixes of Sandy Land

沙生植物是沙区重要的自然资源之一,沙地基质流动性对沙生植物的生长与分布有重要影响。而沙生植物也形成了对其特殊的生态适应对策。文章从4个方面回顾了我国沙生植物的生长对沙地基质流动性响应的主要研究进展,指出了研究中存在的一些分歧,并分析了沙生植物的生长与沙地紧实度及相关的主要生态因子之间的互馈关系,指出了需要进一步深入开展的研究方向及内容,旨在为干旱半干旱沙区植被恢复与重建中防风固沙植物种选择、合理配置、植物资源合理利用与管理提供科技支撑。

Psammophyte is one of the important natural resources in the sandy land regions.The mobility of sandy land surface plays a very important role in growth and distribution of psammophyte and psammophyte also formed the special ecological strategy to adapt this situation.This paper reviews and summarizes the research progress of the response of the growth of Psammophyte on mobility of sandy land surface in four aspects.The relationship between the growth of psammophyte and the compaction of sandy land and other related ecological factors were analyzed;the directions or contents that needed for further deep-going research was pointed out.This paper aims to provide scientific and technological support for species selection,rational allocation for windbreak,rational utilization and management plant resources in vegetation restoration and reconstruction in arid and semiarid area.
