摘要:
以广西大青山林区西南桦人工林为研究对象,通过调查测定47块临时样地的常规立地因子和西南桦生长状况,应用主成分分析、数量化理论Ⅰ等方法探讨立地指数与立地因子间的关系,系统评价西南桦人工林立地生产潜力。结果表明,坡位、海拔、土壤养分、坡向、坡度、土壤质地和土壤容重7个立地因子与立地指数数量化拟合的复相关系数为0.964,达极显著水平(P<0.01);7个因子中,坡位、海拔和土壤养分对立地指数的贡献达59.36%,且影响均极显著。采用坡位、海拔和坡向3个因子组合划分立地类型,并对47个样地所属立地类型的立地质量进行分析得出,西南桦喜温凉气候,在较高海拔,阴坡、半阴坡立地栽培时生产力较高。
Abstract:
 Conventional site factors and tree growth performance were investigated in 47 temporary sample plots of Betula alnoides plantations at Daqing Mountain in Guangxi.Relationship between site index and site factors was explored through principal component analysis and quantification theory I so as to evaluate site potential productivity of B.alnoides plantations.The results showed that site index fitted significantly (P<0.01) with seven site factors,including slope position,altitude,soil nutrition,slop orientation,degree,soil texture and soil bulk density,and the multiple correlation coefficient of quantified model was 0.964.The contribution rate of slope position,altitude and soil nutrition to site index reached up to 59.36%,indicating a highly significant correlation in the quantified model.Combination of slope position,altitude and slope orientation was used to classify site type and then evaluated site quality of 47 plots,it was indicated that B.alnoides liked “warm-cool” climate,and was of high site productivity when planted at sites with higher altitudes,shady or semi-shady slopes.
