安徽省长江以北刺槐的立地类型划分

以安徽长江以北刺槐标准地和解析木的资料为基础，采用综合多因子与主导因子相结合、多级序与逐级控制相联系、科学性与实用性兼备的原则与方法，对该地区刺槐产地进行了立地类型的划分。提出了以地貌、气候、局部地形、土类及土壤因子为主要依据的三级分类系统。共划分出２个刺槐立地类型区（６个立地类型亚区）、９个立地类型组、２９个立地类型。

SITE CLASSIFICATION OF ROBINIA PSEUDOACACIA IN THE AREA NORTH OF THE YANGTZE RIVER ANHUI PROVINCE

Based on the surveying data of 108 sample plots and the stem analysis of 176 sample trees of Robinia psedoacacia in the area north of the Yangtze River, Anhui province, a comprehensive principle, combing multi factor with a dominant factor;integrating multi class sere with gradation of class control;as well scientific with practical, were employed to classify the site types of Robinia pseudoacacia plantation.A three class classification system in terms of some major factors,such as landform,local topography, climate,soil types, was proposed. Total 2 regions of site types,6 subregions of site types,9 sections of site types,and 29 site types were grouped in the paper.
