Shuitu Baochi Xuebao目的紫色土土壤退化形势严峻，水体流失严重，土壤增碳固碳困难，为探究碳源添加对紫色土坡耕地碳固存的影响。方法以四川紫色土坡耕地为对象，在10°紫色土坡耕地设置不施肥(CK)、化肥+秸秆还田(T1)、化肥+秸秆生物炭(T2)、化肥+牛粪(T3)、化肥+有机改土基质(T4)、化肥+生物炭牛粪菇渣堆肥(T5)6种处理，每种处理重复3次。分析降雨量及不同碳源处理下径流、泥沙、碳质量分数的变化特征。结果1) 降雨量＞30 mm，短时强降雨(16.1 mm/h)可促使地表径流的产出。碳源添加可显著减少地表径流量(p ...

Shuitu Baochi Xuebao, 2019 以威海仙姑顶中度火烧迹地人工更新后的麻栎-樱花-刺槐混交林（MYC）、麻栎-黑松-五角枫混交林（MHW）、麻栎-黑松-黄栌混交林（MHH）和麻栎-黑松-臭椿混交林（MHC）为研究对象，对4种不同造林模式进行土壤的定量分析和物种多样性调查，以自然更新林地（CK）作为对照，对比分析不同造林模式对火烧迹地土壤修复效果以及林下植被更新状况。结果表明：（1）MHH在0—40 cm土层内土壤容重最小，土壤通气性能最佳，土壤持水状况最好，MHC次之，MYC最差，但均与CK存在显著差异（P0.05））（3 ...
