摘　　要：为了解黔西南天然川榛(Corylus heterophylla Fisch.var.sutchuenensis Franch)林土壤养分的基本状况,为黔西南天然川榛林的驯化和开发利用,以及喀斯特石漠化生态恢复与区域发展提供参考,以黔西南天然川榛(Corylus heterophylla Fisch.var.sutchuenensis Franch)林为研究对象,通过样方设置及样点布设进行土壤样品采集,测定分析其林地土壤养分情况,结果表明天然川榛林与杂木林土壤养分状况存在显著差异(p<0.05);天然川榛林地土壤有机质,土壤全N、P,有效态N、P、K均高于杂木林地,仅有全K、有效S含量低于杂木林地。This paper aims to study the basic condition of soil nutrient in the natural Corylus heterophylla Fisch.var.sutchuenensis Franch forest in the southwest of Guizhou province,serve for the domestication,development and utilization of natural hazelnut,and also provide reference for the ecological restoration and regional development of rocky desertification in Karst areas.Natural forest of Corylus heterophylla Fisch.var.sutchuenensis Franch in southwest of Guizhou is chosen as research object.Through quadrat setting and sampling point arrangement to collected soil samples,the soil nutrient status of natural forest of Corylus heterophylla Fisch.var.sutchuenensis Franch and shaw is determined and analyzed.The research finding shows significant differences between natural forest of Corylus heterophylla Fisch.var.sutchuenensis Franch and shaw(p<0.05).Soil organic matter in wild natural forest of Corylus heterophylla Fisch.var.sutchuenensis Franch,soil N,P,available N,P,K are higher than shaw,only the content of full K,effective S in Natural forest of Corylus heterophylla Fisch.var.sutchuenensis Franch is lower than shaw.The results can provide scientific guidance for developing and protecting wild hazelnut resources and improving the ecological environment of Karst mountainous areas in southwest of Guizhou province.
