Study on Soil Organic Matter and Total Nitrogen Content of Wuyi Mountain Scenery Spot

The spatial variability characteristics of soil organic matter and total nitrogen content of Wuyi mountain scenery spot in 2008～2010 as well as the relationship between distribution pattern of vegetation and altitude and soil organic matter and total nitrogen were analyzed.The results showed that firstly,surface soil organic matter and total nitrogen content increased with the increase of altitude.And the spatial distribution of soil organic matter and total nitrogen content was determined by comprehensive function of climate and vegetation.Secondly,there was spatial correlativity for soil organic matter and total nitrogen in 0～20 cm,20～40 cm,40～60 cm soil layers.The level of soil depth and content of organic matter and total nitrogen was negatively correlated.The organic matter in 0～20 cm soil level accounted for more than 40% organic matter in 0～60 cm soil level,even up to 66.33%.Thirdly,the content of soil organic matter and total nitrogen in Wuyi mountain scenery spot was generally stable,showing that soil organic matter and total nitrogen was kept well during tourism development.
