对重庆武隆岩溶区五个土壤剖面的粒度特征进行了分析,并将其粒度参数、粒度曲线、结构参数散点图等与各种沉积环境下的沉积物粒度特征进行对比,发现研究区样品的粒度特征与河流相沉积物、湖泊沉积物、坡积物等物质的粒度特征差异较大;与黄土高原红粘土、黄土古土壤、镇江下蜀土的粒度特征存在相似性,但仍有一定差异;与贵州碳酸盐岩上覆堆积物的粒度特征有较为一致的特性.根据五个土壤剖面的粒度特征推测,其沉积过程中溶蚀作用占主导,与先前风化形成该土层的原岩层性质有关,并有一定风成成因,同时还与坡面流水有一定关联.
The grain size characteristics of five soil profiles in the Wulong karst area of Chongqing were analyzed, and their grain size parameters, grain size curves, structural parameters and scatter plot were compared with those of sedimentary environments. It was found that the sample size The characteristics of grain size are quite different from those of river sediments, lake sediments and slope sediments. Comparing with the grain size characteristics of red loam, loess ancient soil and Xiashu loess of Loess Plateau, Which is consistent with the grain size characteristics of carbonate overlying sediments in Guizhou Province.According to the grain size characteristics of the five soil profiles, it is presumed that the dissolution process is dominant during the deposition process, Related, and have a certain cause, but also with the slope of a certain relationship between water.
