Soil Fertility of Different Stand Types in Fuxin Region

Su Ying;Forestry Design Team,Fuxin Mongolian Autonomous County,Liaoning Province;  
In order to explore the soil fertility of different forest types in Fuxin area,six kinds of forest stands(two kinds of coniferous forest,two kinds of broadleaf forest and two kinds of mixed forest)were studied in this area,And soil enzyme activities of the relevant indicators of soil fertility levels were analyzed.Result shows that different forest types of soil nutrients and enzyme activity have clear differencesi,in terms of comprehensive performance of soil fertility,the broad-leaved forest is optimal,followed by the mixed conifer;the coniferous forest is the weakest,and the shrub forest and the secondary forest are optimal than the artificial forest.The specific fertility levels of six kinds of forest soils are as follows:Prunus mongolica shrubsQuercus mongolica secondary forest mixed forest of Pinus tabulaeformis-Quercus mongolicaartificial pure forest of Pinus tabulaeformis mixed forest of Pinus tabulaeformis-Pinus sylvestris var.mongolicaartificial pure forest of Pinus sylvestris var.mongolica.
