摘　　要：莲花山保护区是重要的城市生态屏障,为了提升生态保护质量和林相改造的科学性,对保护区布设70个调查点同时按不同林地类型的土壤化学性质与养分状况进行了研究。结果表明:莲花山保护区土壤以酸性为主,有机质含量高,水解氮和全氮含量较高;速效磷含量整体上处于中等偏下水平,大部分地区存在缺乏的现象,而且分布不均匀,土壤全磷含量普遍不足,土壤速效钾和全钾含量偏低。研究结果为保护区生态管理和建设提供科学依据和参考。Lianhuashan Nature Reserve is an important urban ecological barrier.In order to improve the quality of ecological protection and the scientificity of forest transformation,the soil chemical properties and nutrients in different forest land types were analyzed in 70 survey sites in the reserve.The results showed that the soil in the reserve was mainly acidic,with high content of organic matter,high content of hydrolyzed nitrogen and total nitrogen;The content of available phosphorus was generally at the lower level of the middle.There was a lack of phenomenon in most areas,and the distribution was uneven.The content of total phosphorus was generally insufficient,and the content of available potassium and total potassium were low.The results provide a scientific basis and reference for the ecological management and construction of the reserve.
