County in the South Branch Mountain is a Nanling Mountains, due to the relationship between geological structure, so that the county mountains and tangled, complex terrain, elevation 500 meters below hilly area of 17.8%, hillside about 25%, compared with flat terrain. Most of the topsoil, compared with deep soil, with an area of about 50 million mu, mostly sandstone and shale, red sandstone and shale, limestone types, is a hilly red loam distribution area. Due to climate warm, humid, rainy, so lush plant growth is conducive to organic matter decomposition and synthesis. But the rain is bringing a strong soil erosion, leaching, resulting in more serious soil erosion, thin ridges, acidic, than the lack of nutrients. Most of the slope was defective virgin forests and forests are covered by most of the cultivated slope land, some for the terrace or tea and orchards. Such slopes are mainly distributed in the county dam, white earth, Longgui, Wushi, camphor City, Shuda, bridges, Chongyang, plow city, the town of Maple Bay.
