摘要
Soil moisture regime is an important component of forest land classification at the local level, and in Quebec, it is a criterion for many decisions concerning forestry activities. To facilitate consistent evaluation of soil moisture regime, dichotomous keys were developed for the Abitibi-Temiscamingue region of northwestern Quebec using topographic and edaphic variables and a nonparametric discriminant classification procedure. Probability of correctly classifying a new observation ranges between 63 and 71%, whereas 98-99% of the observations are classified in their moisture class of origin or in an adjacent class.
