Abstract

This study analyzed the impact of the climate conditions to the larch early falls occurrence and development by used statistical method，weather forecasted the hazard area and guiding significance on forestry pest disaster prevention work. This article research showed that warm and humid climatic conditions suitable for larch early fall disease favored；whereas high temperatures and dry conditions is not conducive to the disease occurrence. Winter and spring warm and relatively humid climate favorable bacteria adaptation period of dormancy，safe over-wintering and ascospore produce；A warm and wet climate was more advantageous to ascospore maturity，distribute and infection rate. Through testing on the effect of the forecasting model，the forecasting larch early fall disease was 95.3% accurate，which included absolute error＜5.0% prediction accuracy rate of 62.5%，absolute error＜10.0% prediction accuracy rate of 87.5%. Absolute error of forecasting for 2008 was 2.6%，for 2009 was 7.8%，and for 2010 was 4.7%. The predict and test report met the needs of operational service，this model could provide guidance for forestry pest disaster prevention work. ［Ch，1 fig. 15 ref.］
