Analysis of soil physical characteristics of different forest types at Longfeng Mountain Scenic Area of Kazuo County in the west of Liaoning Province
This study analyzed the soil bulk density,porosity and water holding capacity of 0-30 cm soil in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,the mixed forest of Pinus tabuliformis and Quercus mongolica,the pure forest of Quercus mongolica,the pure forest of Pinus tabuliformis,and the non-forested land in the Longfeng Mountain scenic area of Kazuo County.The results showed that:(1)The soil bulk density was the lowest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 1.20 g.cm-3,followed by the second in the mixed forest of Pinus tabuliformis and Quercus mongolica,which was 1.26 g.cm-3,and the highest in the non-forested land,which was 1.49 g.cm-3.(2)The total porosity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 47.47%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 44.66%,and the lowest in the non-forested land,which was 38.75%.The capillary porosity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 43.71%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 41.35%,and the lowest in the non-forested land,which was 36.65%.The non-capillary porosity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 3.75%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 3.30%,and the lowest in the non-forested land,which was 2.11%.(3)The maximum water holding capacity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 41.95%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 35.68%,and the lowest in the non-forested land,which was 27.78%.The capillary water holding capacity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 38.81%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 33.55%,and the lowest in the non-forested land,at 26.07%.The field water holding capacity was the highest in the mixed forest of Pinus tabuliformis and Armeniaca sibirica,with a value of 18.78%,followed by the mixed forest of Pinus tabuliformis and Quercus mongolica,with a value of 16.79%,and the lowest in the non-forested land,which was 12.19%.It can be seen that in reducing soil bulk density,increasing soil porosity and enhancing soil water holding capacity,the Pinus tabuliformis and Armeniaca sibirica mixed forests and Pinus tabuliformis and Quercus mongolica mixed forests were superior to the Quercus mongolica pure forest and Pinus tabuliformis pure forest,and the pure forests were superior to the non-forested land.Therefore,for soil and water conservation forest in the scenic area of Kazuo County,the mixed forests are better than the pure forests to play the role of forest ecosystems in water conservation.
