[目的]从桂西北岩溶地区常见石山植物中筛选出生态-经济综合效益较好的优良先锋种.[方法]用硫代巴比妥酸法、磺基水杨酸法分别对65种常见石山植物叶片中的丙二醛和脯氨酸含量进行了测定,用数理统计方法对丙二醛和脯氨酸含量的相关性进行分析,并对65种石山植物进行聚类分析.[结果]石山植物叶片中的丙二醛含量为0.0052～0.0381μmol/g,不同植物之间丙二醛含量差异较大;所测定的植物叶片中的脯氨酸含量为4.347～374.956μg/ml,不同树种之间脯氨酸含量差异也较大;丙二醛和脯氨酸含量可以作为岩溶地区先锋植物选择的参考指标,但在选择先锋植物时不仅应考虑物种自身的生物学特性,还应考虑岩溶环境的差异性和生态经济效益以及物种的合理配置.[结论]黄连木、任豆、台湾相思、伊桐、国槐等可以作为桂西北岩溶地区石山绿化首选的优良先锋树种,与广西石山造林和植被恢复的实际情况比较一致.

[Objective]To select excellent Pioneer species of better ecological and economical Comprehensive benefits from the common rock hill Plants in Karst area in northwestern Guangxi Province.[Method]Determine the contents of malondialdehyde and proline in leaves of 65 strains of plants by thiobarbituric acid method and sultosalicylic acid method, analyze the relevance of the Contents of malondialdehyde and proline by mathematics statistics and analyze the 65 kinds of rock hill plants by clustering[Result]The contents of malondialdehyde and proline are 0.0052-0.038 1μmol/g.There are comparably significant differences in the contents of malondialdehyde in different plants;The determination of proline contents in plant's leaves are 4.347-374.956, μ/ml.There are also significant differences in proline of different leaves of rock hill plants.The contents of malondialdehyde and proline can be used as a reference point in selecting pioneer plants in Karst area.But when we select the pioneer plants, not only the biological characters of the species themselves should be taken into consideration, but also the differences of Karst area environment, ecological and biological benefits and the reasonable distribution of species.[Conclusion]Pistacia chinensis, Zenia insignis, Acacia confusa, Itoa orientalis and Sophora japonica can be used as the first choices of excellent pioneer plants in Karst area in northwestern area which comparably consists with the real situation of afforestation of rock hills and recovery of plants in Guangxi.
