摘　　要：兰考泡桐（Paulowniaelongata）是淮北平原砂姜黑土上的主要造林树种．为了提高造林质量，提高林业经营与决策的科学水平，开展了该区兰考泡桐立地类型划分、立地质量评价及生长模型的研究．通过调查该立地上兰考泡桐的生长情况．应用数量化理论筛选该类土壤影响兰考泡桐生长的主导因子，划分了9个立地类型．应用Richards函数为导向曲线，以平均优势木胸径为评价指标，导出了地位指数模型．编制了数量化地位指数得分表，实现了有林地与无林地的统一评价．根据兰考泡桐在这一地区栽培密度小的特点，建立了平均本胸径和平均本材积的单木生长模型．Through investigating the growth of Paulownia elongata on Shajiang black soil of Huaibei Plain and applying a quantitative theory to Select the principal factors thataffect Paulownia elongata growth,the soil region has been divided into 9 site types. By using Richards function as the guide curve and BHD of average superior trees as the appraisal target,a site index model has been set up,and a site index mark table has been compiled. The latter makes it possible to consistently appraise the site quality of both forestland and non-stocked land in a saing system. Considering that the planting density ofPaulownia elongata in the region is small,this paper has also established individual tree growth models for average trees' BHD and timber volume.
