Based on the destroyed and degraded ecosystem by the powerful earthquake in seismic areas, vegetation restoration was discussed in reconstruction of different ecosystems.
本文从地震对震区生态系统的破坏和退化出发，探讨了不同生态系统重建中植被恢复的技术和做法。
The main results are as follows: 1 . Woody plant density in degraded ecosystem is in close relation with restoration stage of vegetation.
结果表明：1。退化生态系统木本植物的密度与植被的恢复阶段紧密相关；
Therefore, appropriate plant species and restoration approaches should be chosen to restore the vegetations of degraded karst ecosystem.
因此，退化喀斯特生态系统的植被恢复必须选择合理的物种和恢复方式。
