摘要

运用土壤粒径质量分布原理与分形理论

研究泥石流频发区蒋家沟3种不同盖度草地土壤粒径分形特征。结果表明:不同盖度草地的土壤粒径分布具有不同的分形特征

其分形维数在2.520 8～2.669 1之间

其关系为:低盖度草地>高盖度草地>中盖度草地;不同盖度草地土壤分形维数与<0.002 mm

0.05～0.002 mm粒径含量呈极显著正相关

土壤的颗粒越小

细粒含量越高

分形维数越大;分形维数与土壤容重呈显著正相关

与有机质含量呈显著负相关。土壤粒径含量、土壤容重、有机质是表征土壤理化性质的重要参数

对土壤肥力状况、结构稳定性及抗蚀性能有着重要的影响。因此

土壤颗粒的分形维数可作为表征土壤结构和性质的重要参数

也可作为土壤抗蚀性的指标之一。研究结果可为研究区植被恢复和土地利用开发提供一定的理论依据。

Abstract

According to the quality principle of soil particle size distribution and theories of soil fractal

characteristics of soil particle fractal under 3 typical coverage grasslands of the area with high-frequency debris flow were studied in Jiangjiagou ravine.The research showed that:Under different coverage grassland

soil particle size distribution had different fractal characteristics

its fractal dimension was between 2.520 8 to 2.669 1

and the order was low coverage grassland>middle coverage grassland>high co...
