中文摘要	喀斯特地区种植桉林是恢复和改善岩溶地区生态环境及推进脱贫致富的重要措施,但其生态环境影响也是广泛关注的科学问题。选择广西桂林、扶绥两处地点,对比分析了红壤和喀斯特土壤种植桉树对土壤结构和土壤养分的影响,结果表明:(1)喀斯特地区桉林土壤容重略大于红壤、毛管孔隙度不发达,非毛管孔隙度较发达,总孔隙度小于红壤;(2)喀斯特地区桉林土壤非毛管含水量显著低于红壤,但饱和含水量基本相当;(3)喀斯特桉林土壤的全量养分多高于红壤,而一些速效养分低于红壤,尤其是钾的含量显著偏低;(4)喀斯特桉林土壤的pH值和有机质含量高于红壤。研究表明喀斯特地区种植桉树人工林并未引起土壤结构的破坏和土壤养分含量的显著降低,相反在某些方面喀斯特地区种植桉树相对于红壤还有其优势。最后,结合研究结论,该文还就喀斯特地区和红壤地区桉树人工林管理提出了一些针对性建议。
英文摘要	Planting eucalyptus is an important way to restore and meliorate the ecological environment, overcome poverty in karst desertification areas. It is also a hot issue in scientific field. This article took Guilin, Husui of Guangxi as examples to contrast the effect of planting eucalyptus on soil structure and soil nutrient in different soil type (red earth and Karst soil). The results were: (1) contrasted with red soil, Karst soil had higher soil bulk density and non-capillary porosity, less capillary porosity and total porosity; (2) the capillary moisture of Karst soil was significantly less and the saturation moisture was basically the same; (3) the total nutrient of Karst soil was relatively higher and some kinds of available nutrient, especially K, were relatively less; (4) the pH and organic matter content were relatively higher. These results indicated that planting eucalyptus in karst area did not result in soil structure destruction and nutrient loss. However, Karst soil even had some advantages in eucalyptus planting. At last, some countermeasures about eucalyptus plantation management in Karst and red soil area were put forward.
