Abstract: According to investigation on the disaster of non-commercial forest subcompartment of whole Zhejiang,it was found that around 78.15×10^{4<.sup> hm2 of the 200×104 hm2 non-commercial forest in the province was stricken by the spring sleet freezes in 2008.The seriously stricken area(I.e.,the ratio of damaged forest ≥30%)reached to 23.33×104 hm2,and the stricken parts mainly consisted of the extremely important ecological areas and the areas whose ecological environment was very fragile,such as headwaters and natural reserves etc.Based on a preliminary estimation,the direct economic loss caused in the snow disaster was 26.08×108 yuan,the biological matters were reduced by 1 172.61×104 t and the various ecological losses in the forthcoming 10 years would reach to 942.71×108 yuan.The countermeasures and suggestions,including comprehensively monitoring and evaluating impacts of the sleet freezes disaster on local environment,research on restoration technology for the damaged non-commercial forest ecosystems and implementation of reconstruction projects,have been proposed for reconstruction after the disaster in the end of the article.}
