Abstract:: This paper systematically studied the influences of the different vegetation on the soil total nitrogen (TN) and organic matter (OM) in the wind-water erosion crisscross region in China.The results show that (1) The content of TN and OM decline with the increase of the soil depth within the 0-40cm,and become steady under the depth of 40cm.Under the different conditon of vagetation,the value of soil C/N changes few with the depth,within the 0-200cm depth,the averaged value of soil C/N in deserted aricultural land is the largest,and the averaged values of soil C/N fluctuate with range of 6.7～7.7.Within 0-20cm,the value of C/N in Pinus Tabulaeformis land become the summit with 10.3,and the value is the smallest with 5.99 in the elm land.(2) The value of TN under the vegetati on of Artemisa arenaria and Astragalus adsurgens land is distinctly larger than the other vegetation,the Pinus Tabulaeformis and the elm have the smallest TN.(3) Within 0-20cm,the soil OM in the Artemisa arenaria is the largest,and the smallest in the elm land.Within 20-40cm,the content of OM in Artemisa arenaria land decrease greatly,however the OM in the deserted agricultural land become the peak,and then the Astragalus adsurgens,the black bean land,still the elm land has the smallest value of soil OM.Generally,within 0-200cm,the deserted agricultural land has the largest content of soil OM,and the elm land has the smallest one.The Pinus Tabulaeformis can improve the OM at the shallow soil layer.
