植物生理的研究在岩溶环境植被恢复中的应用

Application of the Study of Plant Physiological Indices to Vegetation Restoration in Karst Environment

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。

Ecosystem in Karst area was flimsy,it affected the absorption of plant to nutritious elements,and hampered the normal growth of plant,in order to do the ecological restoration better in Karst area,the most important thing was vegetation restoration in this area,so we needed to select the fitted plant in Karst area,and construct a steady Karst woods ecosystem which was biological diversity,so that the ecosystem developed rapidly and healthily.In order to select the fitted variety in Karst environment from nu...
