Vegetation Recovery in Karst Areas in Central Guizhou, China

贵州普定喀斯特植被恢复进程研究（英文）

Due to the unique environment of karst landscapes, there are many uncertainties regarding the recovery of vegetation following human disturbance. Through standard wood parsing and growth ring investigation in Puding county in Guizhou province, China, we studied the process of vegetation restoration in karst areas. According to our results, during the recovery of karst vegetation height increases and ground diameter enlargement of tree layers occurred. Increases in the height and ground diameter followed logarithmic and growth curves, respectively. The development time of trees showed continuity, and growth points were randomly distributed. However, with large propagule quantities, vegetation can be directly restored and developed into a secondary high forest without a grass filling stage, and the recovery time is shortened.

喀斯特地区由于其环境的特殊性,人为干扰后植被的恢复有很多不确定性。在普定进行标准木解析和年轮调查,对喀斯特地区植被恢复进程进行研究。结果表明,喀斯特植被在恢复过程中,乔木层表现为高度增加、地径增粗,高度、地径的增长分别呈现对数、乘幂曲线,乔木发育时间连续,生长位置随机分布;而在繁殖体大量存在的情况下,植被可以直接由草灌阶段恢复发育形成次生乔林,且恢复时间明显缩短。
