岩溶环境生态脆弱,影响了植(作)物对营养元素的吸收,妨碍了植(作)物的正常生长发育,做好岩溶地区的生态修复工作,最重要的就是该地区的植被恢复,这就需要选择岩溶环境适生植物,建立起具有生物多样性的稳定的岩溶森林生态系统,以保证系统能迅速地朝良性方向发展。而为了在众多植物种群中筛选出具有岩溶环境适生特性的品种,就需要首先对岩溶环境适生植物的生理特性诸如叶绿素荧光特性、碳酸酐酶活性、稳定碳同位素组成等作深入的研究,进而为建群种的选择提供一定的理论依据。
The fragile ecological environment of karst environment affects the absorption of nutrient elements by plants and hinders the normal growth and development of plants and plants, and completes the ecological restoration work in karst areas. The most important factor is the restoration of vegetation in this area It is necessary to choose suitable plants for karst environment and establish a stable karst forest ecosystem with biological diversity so as to ensure that the system can rapidly develop in a benign way. In order to select suitable plant species with karst habitat characteristics, we must first conduct a thorough study of the physiological characteristics of the plant, such as chlorophyll fluorescence, carbonic anhydrase activity and stable carbon isotope composition, And then provide some theoretical basis for the choice of building species.
