一、黄壤资源概况 黄壤广泛分布于中亚热带的高原山地上。以贵州高原的面积较大。贵州黄壤集中分布在黔中、黔东北、黔东南、黔南和黔西北海拔1000米左右的高原面上,面积约10220万亩,占全省土地总面积的39.16％。 在水平分布上,黄壤与红壤属同一纬度带,但黄壤形成于湿润的生物气候条件下,热量较红壤略低,雾日比红壤区多一半以上,日照少30～40％,各月湿润度>1。
First, the yellow soil resources Overview Yellow soil is widely distributed in the subtropical plateau mountains. Guizhou plateau area larger. Guizhou yellow soil concentrated in central Guizhou, northeast, Qiandongnan, Qiannan and Qianxi elevation of about 1,000 meters above the plateau, an area of about 10220 acres, accounting for 39.16% of the total land area of the province. In horizontal distribution, yellow soil and red soil belonged to the same latitude zone, but yellow soil was formed under humid bioclimatic conditions with slightly lower calorific value than red soil, more than half of which was in foggy day and 30-40% less in sunshine, and the monthly wetness > 1.
