摘要
依据红皮云杉人工林分布区内１２个项目的气候资料和平均优势高之间相关分析，筛选出影响优势高生长的主导因子，进行逐步回归分析，建立起３个气候因子和平均优势高的数学模型。对其可靠性和精度进行了分析和检验，根据生产力等级相似性和差异显著性原理，进行了栽培区划，给出各栽培区、亚区的水热特征临界值指标。并对其区划结果进行了水热因子和生产力两项差异显著性检验，确定栽培区的合理性、科学性。
According to the relationship between climatic data which contain twelve items and average advantage height in Picea Koreainsis plantation distribution district,we make out the main factors which affect advantage height.Three mathmatic models are built between factors and average advantage height through the regression analysis step by step,and their reliability was analyzed and examed.According to the grade similarity and significance of difference of the productivity,we make cot the planting district of Picea Kdreainsis,and give out the hydro-thermal index.We can determine whether the planting district is right and scienific by examing the bias of hydro-thermal index and productivity of Picea Koreainsis plantation.
