岩溶区植物生态适应性研究进展

Research advances in plant ecological adaptability in karst area

对岩溶植物在强光高温、干旱、土壤养分和生境异质性等岩溶典型环境下适应性的相关研究进行了综述。结果发现:强光高温和地质性干旱迫使植物改变自身生理结构和形态结构来应对岩溶环境所带来的损伤;特殊的土壤性质也使岩溶植物进化出较强的生化调节功能;空间异质性与植物功能性状的关系是近些年来国内研究的热点。目前在岩溶植物适应特殊生境方面研究有较大进展,但在研究广度上存在不足,应加强群落演替与不同功能性状间关系等方面的研究,为岩溶区生态恢复治理提供依据。

We reviewed the research progress on ecological adaptability of plants to karst environments, including high light and temperature, soil drought, soil nutrient and habitat heterogeneity. High light and temperature, geological drought force plants to change their physiological and morphological characters to cope with the damage caused by karst environment. Special soil properties also enable karst plants to evolve strong biochemical regulatory functions. The relationship between spatial heterogeneity and plant functional traits is a hot topic in recent years. At present, there has been great progress in the study of karst plants adapting to the special habitat, with some shortcomings in the scope of research. It is necessary to strengthen the study on the relationship between community succession and different functional traits, to provide scientific basis for the ecological restoration of karst area.
