补充资料:棕钙土
棕钙土 brown calcic soil 发育于温带荒漠草原植被下的土壤。地表多砂砾石,剖面上部呈褐棕色,下部为粉末层状或斑块状灰白色钙积层。主要分布于欧亚大陆温带荒漠草原地区,位于栗钙土与漠土之间,从西、北、东三面环绕于漠土外围。中国内蒙古高原和鄂尔多斯高原的中西部、准噶尔盆地的北部、塔城盆地外缘以及中部天山北麓山前洪积扇的上部等地都有分布。棕钙土的形成是以草原土壤腐殖质积累作用和钙积作用为主,并有荒漠成土过程的一些特点。棕钙土的特征有:自然植被组成趋于旱化,生物量低,土壤腐殖质积累作用弱,有机质含量低;钙积作用强,钙积层在剖面中位置较高;呈碱性至强碱性反应,阳离子交换量较低,吸收性复合体为盐基所饱和,其中钠离子所占比例较高;质地较粗,多属砂砾质、砂质和砂壤质、轻壤质,土体中钙质有较明显移动。棕钙土地区以畜牧业为主,仅局部地区有灌溉农业。热量条件虽较好,部分地区且可进行复种,但水分条件较差,土层浅薄,矿质养分含量低;加之春季风大和侵蚀严重,需进行水利建设、营造防风林带,并采取种植绿肥、增施有机肥及矿质肥料等改良措施,才能进行农业生产。畜牧业的持续发展,也有赖于地下水源的开发和建立小型分散的人工草料基地。 |
