武功位于关中西部,除沿河地区外,地下水一般埋藏较深。年平均温度为12.8℃,年降雨量469.5—979.7毫米,平均657.6毫米(1954—1973)。降水在多数年份可渗入土壤2—3米。个别年份达5米,甚至可补给地下水。就整个土层而言,表层水分变动较大,雨季可达饱和或田间持水量状态;旱季或旱年,水分可降至凋萎含水量以下。而在较深的土层中,土壤含水量则常年保持在15％左右。
The martial arts are located in the central and western Guanzhong. In addition to river areas, groundwater is generally buried deeper. The annual average temperature of 12.8 ℃, annual rainfall of 469.5-979.7 mm, an average of 657.6 mm (1954-1973). Precipitation in most years can penetrate the soil 2-3 meters. Individual years up to 5 meters, and even recharge groundwater. In terms of the whole soil layer, the surface water content fluctuates greatly, and the rainy season can reach the state of saturated or field water holding capacity. In the dry or dry years, the water content can drop below the wilting water content. In the deeper soil, the soil moisture remained at perennial about 15%.
