摘要
为深入了解森林火灾对寒温带落叶松林的影响,为灾后森林恢复提供有益指导,选取位于中国呼国家级自然保护区内的2010年火灾迹地作为研究区,对不同火灾强度下的土壤理化性质进行分析。结果表明,随着火灾强度的增加,土壤中的微生物碳含量(MBC)、水分含量(MC)、总氮含量(TN)及速效磷含量(AP)显著增加(P<0.05),而速效钾含量(AK)则显著降低(P<0.05)。通过对呼中国家级自然保护区寒温带落叶松林火灾后土壤理化性质的研究,为火灾后的植被恢复及重建提供参考。
In order to deeply know the influence of forest fires on Larix larix forest in the cold temperate zone,and provide useful guidance for forest restoration after the disaster,the study selects the fire sites in 2010 in Huzhong National Nature Reserve of China as the research area,and analyzes the soil physicochemical properties under different fire intensification.The results show that with the increase of fire intensity,microbial carbon content(MBC),water content(MC),total nitrogen content(TN)and available phosphorus content(AP)in soil is significant(P<0.05),while available potassium content(AK)decreases significantly(P<0.05).The study on soil physical and chemical properties of Larix larix forest after fire in Huzhong National Nature Reserve provides reference for vegetation restoration and reconstruction after fire.
