山地棕壤

亚高山温性落叶阔叶林山地棕壤和中山常绿落叶针阔混交林山地黄棕壤中根孔类大孔隙广泛分布，染色面积比例高。

Root soil macropore is extensively distributed in warm-temperate deciduous broad-leaved forest and mountain brown earth at subalpine zone and evergreen-deciduous broad-leaf mixed forest and mountain yellow brown earth at mid-mountain zone and the proportion of dyeing area is large .

其主要土壤类型为山地黄棕壤和石灰土及局部的山地沼泽土。

The main soil types are mountain yellow-brown earth and limestone soil , and mountain marshy soils in localized areas .

选用南方草地土壤&山地黄棕壤进行盆栽试验，研究了氮锌复合作用对混播系统白三叶生长、根瘤发育、固氮及固氮产物转移的影响。

Influences of the compound effects between nitrogen and zinc on growth , N-fixation and transfer of fixed nitrogen of white clover in mixed culture ;

土类的有机碳变异性也极大，变异系数以山地酸性棕壤类最大，达95.42%，最小的是岗地砂姜黑土类，为18.92%。

The coefficient of variation in SOC among soil types was also great , with the highest in mountain acid brown type ( 95.42 % ), and with the smallest in mound lime concretion black soil type ( 18.92 % ) .

分布区土壤主要是花岗岩、砂页岩、板岩发育的山地黄壤和黄棕壤。

Soil of distribution is brown soil and yellow-brown soil which developed from granite , sandy shale , slate .

在山地黄壤和山地黄棕壤的分布地带内，尚有石灰土及低洼地的山地沼泽土和水稻土。

In the area distributed with mountain yellow carth and mountain yellow-brown earth , there is limestone soil , and mountain marshy soils and paddy soils in smaller depressions .

从粘粒矿物组成和SiO2/Al2O3，判断，皖南山地上部不存在山地黄棕壤和山地棕壤。土壤垂直带谱主要由黄红壤和黄壤构成。

Judging by the characteristics of the composition of the clay minerals and the silica-alumina ratios of clay , there are no mountain yellow-brown soil and mountain brown earth on the upper parts of the mountains in the southern Anhui Province .

大围山土壤分布自下而上依次为山地红壤、山地黄壤、山地黄棕壤和山地灌丛草甸土，在海拔1100m以上的山间盆地和凹地间有草甸、沼泽土分布。

Soil distribution from the foot to the top were : mountain red soil , mountain yellow soil , mountain yellow-brown soil and mountain meadow soil . Above the 1100 m of absolute altitude of the intermountain basin is bog soil .

由于垂直地域分异作用，山地红壤的敏感性较大，其次为山地黄棕壤，山地黄壤为不敏感土壤；

Due to the effect of vertical zonality , the sensitivity of the mountain red soil is the highest , that of the mountain yellow brown soil the next , and that of the mountain yellow earth the least .
