摘要:

生态脆弱性已成为当前全球变化与可持续发展研究中的热点问题。中国西南岩溶生态系统作为特殊的生态系统,具有与其他地区不同的脆弱性特征,其脆弱性评价研究也比其他地区开展得更加广泛和深入,查阅和整理了近几年的相关期刊中关于岩溶生态脆弱性评价的文献,回顾和总结了研究指标、研究方法、研究内容等方面的研究,分析了目前岩溶地区的生态脆弱性评价,指出了岩溶生态脆弱性评价研究中仍然存在一些亟需解决的问题,指出要加强人地系统对区域及全球极端自然灾害的响应研究,特别是利用合适的生态模型对区域的生态脆弱性进行评估和模拟,为地区生态保护和生态恢复与重建提供重要依据。

Abstract:

Ecological vulnerability has been highlighted in the studies of global change and sustainable development in recent years. The vulnerability of karst ecological system in southwest china is different from those of other places because of its specialty and the research on vulnerability of karst ecological system has developed more widely and deeply. This article collected, consulted and analyzed related literature data about karst ecological vulnerability of SW China, which have been reported in resent years. It brought a systematic summarization on the basis of research index, methodology and content, the results show: in present, the evaluation on vulnerability of karst ecological system is based on analysis of features and influencial factors as well as building index systems of it which is emphasized. Step analysis is the most popular method. Contents of study have mainly on water, soil, vegetation and the interconnections with other environmental factors. In resent years, a introduction of RS and GIS has made a great progress in research. Nevertheless, there have been some problems about evaluation of vulnerability of karst ecological system to be solved, especially to strengthen research on vulnerability of extreme natural calamities which are related to man-earth relationship in southwest of China. Further more, to introduce proper ecological models to make an evaluation and simulation on regional ecological vulnerability and to provide evidence for ecological conservation, restoration and reconstruction.
