石漠化功能灌木群自组织更新与石漠化治理

Functional shrub community self-organization regeneration and control of rocky-desertification on karst region

植物性状反映了植物对生长环境的响应和适应,石漠化功能灌木群是石漠化生态系统植被恢复中不可替代的植物群,其对环境响应表现的行为性是退化生态系统自我恢复、保持系统稳定的重要方面.文章概述了植物功能群在生态学应用方面的研究进展,回顾和评述了国内外功能灌木群自组织更新对有性繁殖和无性繁殖的响应;并结合西南石漠化综合治理的现状,认为石漠化功能灌木群自组织更新过程及相关机理的研究将是今后石漠化治理研究的重要方向.

Functional shrub community is irreplaceable plant populations in re-vegetation of degraded e- cosystems, and the behavioral performance of plant-environment response is important aspects of self-re- storing ecosystems and maintaining ecosystems stability. The progress of the plant functional groups in the application of ecology and the functional shrub group of self-organization to update the response of sexual reproduction and asexual reproduction in karst were reviewed in this paper. In addition, as for current situation in management of the rock-desertification, it was suggested that rocky desertification functional shrubs group since the process of organizational renewal and related mechanism should be an important direction for rocky desertification control in the future.
