Abstract
According to the daily meteorological data in Heilongjiang Province from 1961 to 2005,the peak width at half height method was adopted to study the eco-geographical changes of Larix gmelinii and Pinus koraiensis during recent 46 years.As indicated by the results,after 1990,the suitable distributing region of Larix gmelinii showed obvious tendency of moving northwards under the change of temperature and rainfall conditions.Due to the changes of thermal condition,the suitable distributing regions of Pinus koraiensis moved 1° northward.
