辽西地区山杏立地条件的主成分-数量化分析

Study on the Site Condition of Armeniaca Sibirica in Western Liaoning Province Based on Quantitative-Theory Ⅰ

通过对辽西地区现有山杏林的大量调查研究,利用数量化理论Ⅰ确定了辽西半干旱地区山杏生长发育的主导因子为坡向和土层厚度,利用主导因子分级组合法,划分为9个立地类型.对各立地类型冠幅生长情况进行了预测,结合主导立地因子性能分析,提出了各立地类型山杏林种、林型的配置.

Based on a lot of investigations in western liaoning province, the main factors affecting on the growth and bearing fruit of Armeniaca Sibirica were found analyzed by.The main factors were slope direction and soil depth. Using the main factors classification and combination, nine site types were classified. According to the forecast of Armeniaca Sibirica＇s canopy width developing which cultivated in various site types, and combining the analysis of main factors＇ capacity, various Armeniaca Sibirica forest sort and forest types for different site types were confirmed.
