中文摘要:
      [目的]选择具有良好防护功能的混交林林分类型,为山东省石灰岩山地森林优化升级提供理论依据。[方法]选取山东省典型石灰岩山地5 a生8种不同树种混交林林分,以侧柏纯林为对照,采用野外调查和室内测定相结合的方法,从混交林林分的生长状况、改良土壤理化性状效益、林地土壤水文效益、土壤减蚀效益3个方面的13个指标(郁闭度、冠幅、树高、土壤容重、总孔隙度、速效氮、速效磷、速效钾、土壤饱和贮水量、稳渗速率、渗透时间、减蚀量、枯落物层厚度)研究其改良土壤与减蚀效益,通过层次分析法(AHP)对不同树种混交林林分进行综合评定。[结果]改良土壤与减蚀效益最好的是苦楝侧柏混交林,其次是刺槐侧柏混交林和黄栌侧柏混交林。[结论]混交林改良土壤与减蚀效益优于纯林,其中苦楝侧柏混交林、刺槐侧柏混交林和黄栌侧柏混交林改良土壤与减蚀效益最佳,适宜石灰岩山地。
英文摘要:
      [Objective] To select the mixed forest types with good protection function, in order to provide a theoretical basis for guiding the optimization and upgrading of limestone mountain forests in Shandong Province. [Methodes] We selected 8 different mixed forests of 5-year-old in the typical limestone mountainous area of Shandong Province, and the Platycladus orientalis forest was used as the control. Field investigation was conducted and quantitative analysis methods were used to study the soil improvement and erosion reduction benefit from three aspects: the growth condition of mixed forests stand and benefit of improving soil physicochemical properties, the soil hydrological benefit of forest land and the soil erosion abatement benefit. Totally, 13 indexes including canopy density, crown width, tree height, soil bulk density, total porosity, available nitrogen, available phosphorus, available potassium, soil saturated water storage, steady infiltration rate, infiltration time, amount of erosion and thickness of litter layer were selected. The comprehensive evaluation of different mixed forest stands was carried out by analytic hierarchy process (AHP). [Results] The P. orientalis+Melia azedarach mingled forest had the best soil erosion reduction benefit, followed by the P. orientalis+ Robinia pseudoacaia and P. orientalis+Cotinus coggygria mingled forest. [Conclusion] The soil improvement and erosion reduction benefit of mixed forests is better than that of pure forests. The soil improvement and erosion reduction benefit of P. orientalis+M. azedarach, P. orientalis+ R. pseudoacacia and P. orientalis+C. coggygria are the best, which is suitable for limestone mountains.
