5 point sampling method was adopted to take soil sample in the Vatica mangachapoi single-species-dominated forest of Diaoluoshan Nature Reserve,Hainan Island.The effects of altitude,soil layer depth,season and soil physical & chemical properties on the soil intensity of nitrification-denitrification were analyzed.The results showed that the altitude and soil layer depth had no significant effect on the soil nitrification-denitrification(p> 0.05).The season had a significant effect on them(p< 0.05),of which the soil intensity of the nitrification-denitrification in a rainy season was dozens to a hundred times higher than that in a dry season.The soil physical & chemical properties had no effects on soil nitrification intensity(p> 0.05),but the total phosphorus,total potassium,available phosphorus,available potassium and moisture content were significantly negative related to the soil intensity of denitrification(p< 0.05). This suggests that the season is an important influence factor,and part of soil physical & chemical properties are one of the important factors affecting soil denitrification intensity in the process of soil nitrogen transformation in the research area.
