In order to study the various labor-saving afforestation mode for the influence of soil, choosing artificial Korean pine ( Pinus koraiensis Sieb) seedling in the mountainous area of Eastern Liaoning Province as the object, taking single-layer sunshade net cover ( typeⅠ) , double-layer sunshade net cover ( type Ⅱ) , black plastic film cover ( type Ⅲ) , and white plastic film cover ( type Ⅳ) labor-saving afforestation measures, researching the surface cover effects on soil temperature, humidity, bulk density, porosity physical properties and soil microbial biomass carbon. Experimental results show that the effort of labor-saving afforestation measures has a significant role in regulating the temperature and water retention on soil, a significant supporting role on sapling growth and no significant effect on soil bulk density and porosity. The effect of regulating soil temperature shown that: typeⅡ>type Ⅲ>typeⅠ>type Ⅳ>check plot;water retention effect shown that:typeⅡ>typeⅢ>typeⅠ>typeⅣ>check plot;soil bulk density shown that:check plot>typeⅠ>type Ⅳ>type Ⅱ>type Ⅲ; soil total porosity shown that: type Ⅳ>type Ⅲ>type Ⅱ>check plot>typeⅠ;soil microbial biomass carbon shown that:typeⅡ>typeⅢ>typeⅠ>typeⅣ>check plot. The seedling of Pinus koraiensis as different conditions shown that: type Ⅱ>type Ⅲ>typeⅠ>type Ⅳ>check plot.
