探究土地利用方式对长江中游小流域土壤团聚体稳定性的影响,为鄂西地区土地合理利用与管理以及土壤结构改良提供借鉴。以下牢溪小流域5种不同土地利用方式（柏树林、蔬菜地、石坎农田、撂荒地、天然林）土壤为研究对象,对比分析各土地利用方式间土壤团聚体粒径组成及稳定性差异。结果表明:（1）柏树林、石坎农田、撂荒地和天然林土壤团聚体以>2 mm为优势粒级,平均为57.66%,蔬菜地以

Soil aggregate is an important indicator of soil quality and sustainable land utilization,and impacts the retention abilities of water and fertilizers.The differences of the aggregate stability in the small watershed scale are sensitively affected by the land pattern of human interference,while the influence of land uses on the aggregate is rarely reported in the small tributary of Yangtze River,located in the hilly region of western Hubei.The purpose of this study was to figure out the effects of five land use patterns(cypresses forests(CF),ve...
