摘要
土壤种子库作为喀斯特山地研究的重要组成部分,其研究成果在深入探讨喀斯特地区植被结构、功能与动态方面具有十分重要而独特的作用。本文系统介绍了该地区种子库的研究方法及主要内容。在对已有成果进行综合分析的基础上,就目前喀斯特土壤种子库研究中亟待解决的一些问题进行了探讨,认为今后应加强森林群落中优势种或建群种土壤种子库动态变化,外来入侵物种土壤种子库动态及其对群落物种多样性的影响机理和土壤种子库在退化植被恢复中的作用与潜力等领域的研究工作,以期为从事西南喀斯特地区土壤种子库研究和该地区植被群落恢复实践提供理论指导。
Soil seed bank is an important part of the study of Karst Mountains,especially for the structure,function,and dynamics of vegetations in Karst region.This paper reviewed the methodologies and main subjects in the study of soil seed bank in this region.Based on a comprehensive analysis on related achievements,some problems to be urgently approached were presented.It was considered that the soil seed bank under dominant or constructive species in forest communities,the dynamic changes of soil seed bank under effects of invasive species and their affecting mechanisms on the species diversity of forest communities,and the roles of soil seed bank in vegetation restoration,etc.,should be further studied,which would provide theoretical guidance for the studies on the soil seed bank and the practices in vegetation restoration in Southwest Karst region of China.
