| 摘 要： | 以环洞庭湖12种主要造林模式防护林为研究对象,对其进行土壤取样和分析,研究环洞庭湖防护林土壤理化性状.结果表明:环洞庭湖区防护林土壤养分处于中高水平,但速效磷比较贫乏；不同造林模式防护林的土壤理化性状存在显著差异,特别是速效氮、速效钾、容重和pH值,其差异性均达到了极显著水平,其中杉木+木荷等针阔混交模式防护林的土壤理...

| Abstract: | Through investigating and analyzing the soil in 12 different forestation models of protection forest surrounding Dongting Lake,the soil physical and chemical properties were studied.The results showed that soil nutrient was at a high level,but relatively poor in available phosphorus.The soil physical and chemical properties were significant difference among different forestation models,especially differences in available nitrogen,available K,bulk density and pH were significant at 0.01 level.The forestation... |
