Abstract:Three typical water conservation forests in Jinyun Mountains were taken as research objects.Soilphysical and chemical properties and soil nutrient characteristics were measured and analyzed.Results showthat:(1)The soil densities of the three forests were all great and the soil bulk density for bamboo forest wasgreater than those for other two forests.The total soil porosity for the three forests was relatively low andthe porous of soil was in moderate level.For the soil texture,the sand content was higher than silt and claycontents.Soils in the forests were in strong acidity,which means that the soil acidification in the area issevere.(2)The soil organic matter content was relatively low and the accumulation of soil organic matterwas better in mixed needle-broadleaf forest and poorer in bamboo forest.For the soil nutrients,the contentof total nitrogen was moderate,the contents of total phosphorus and total potassium were lower,and the soilavailable nutrients were relatively low.(3)Soil conservation function of mixed needle-broadleaf forest wasthe best and the bamboo forest,the worst.Soil ecological function was the best for mixed needle-broadleafforest,followed by mixed broadleaf forests,and the worst for bamboo forest.
