摘要:

为探讨广西桂林天坑资源状况及其植物资源可利用性，对桂林地区的岩溶地貌进行材料收集及实地调查，以了解桂林天坑分布、类型及其主要植物资源。调查发现桂林地区各县分布有17座天坑，且天坑区域的特色植物资源丰富，后期天坑植物种类和植物群落类型多样；早期和中期天坑群落植物组成多为草本和灌木植物，并对具有开发价值的植物进行了分类统计。研究结果为促进景观资源的可持续利用，推动生态产业转型升级，实现桂林喀斯特石漠化地区的可持续发展提供了基础资料。

Abstract:

In order to explore the status of tiankeng resources and the availability of plant resources in Guangxi Guilin,through collecting and investigating the karst landform in Guilin area,the distribution,types and main plant resources of tiankeng were understood.The results showed that there were 17 tiankeng in the counties of Guilin,and the characteristic plant resources in the tiankeng area were rich,the species and plant community types of the tiankeng in the late period were diverse.The plant composition of the tiankeng in the early and middle stages was mostly herbs and shrubs,the plants with development value were classified and counted.The research results provide basic data for promoting the sustainable use of landscape resources,promoting the transformation and upgrading of ecological industry,and realizing sustainable development in the karst rocky desertification areas of Guilin.
