晋西黄土区长期人工林恢复对土壤水分和养分性质的影响

open access: yesShuitu Baochi Xuebao, 2022
黄土高原地区是我国水土流失和环境问题严重的地区之一,人工植被恢复可以有效改善土壤性质,提高土壤质量,明确长期人工植被恢复后土壤水分和养分性质的响应差异,有利于进一步有效改善生态环境。选取晋西黄土区自然恢复的次生林地、人工刺槐林地、人工油松林地3种典型植被恢复类型为研究对象,通过测定土壤物理性质以及有机碳、氮磷钾元素含量等土壤养分,对比分析长期不同人工林恢复条件下的差异。结果表明:(1)次生林地、刺槐林地和油松林地在0-20 cm浅层土壤的容重分别1.15,1.04,1.06 g/cm3 ...

晋西黄土区退耕还林后土壤入渗特征及土壤质量评价

open access: yesShuitu Baochi Xuebao, 2021
为研究晋西黄土区退耕还林后不同植被覆盖下土壤的入渗特征及土壤质量评价,采用野外双环入渗法测定土壤的入渗特征,并测定不同地类土壤的容重、孔隙度、有机质、全氮等指标,使用相关性分析研究不同类型植被覆盖下土壤的入渗性能及其与土壤理化性质的相关关系,并将各地类的土壤理化性质进行主成分分析。结果表明:(1)植被类型对于土壤渗透速率影响较大,表现为天然次生林>刺槐×油松混交林>刺槐纯林>油松纯林>灌木林地>苹果园地>荒草地>农田(玉米地)。(2)退耕还林后,不同植被类型的土壤理化性质差异显著(P灌木林地>苹果园地 ...

晋西黄土区切沟对其上方集水区内土壤水分的影响

open access: yesShuitu Baochi Xuebao, 2022
为掌握黄土高原切沟对其上方集水区内土壤水分的影响,选取晋西黄土区典型切沟上方的集水区为研究对象,采用土钻法定期测量0—10 m土层的土壤水分,探讨集水区内不同地貌部位的土壤水分状况。结果表明:(1)集水区内土壤水分状况受距离切沟远近和地貌部位的共同影响。(2)集水区内距离切沟1 m处的蓄水量显著低于距离切沟3,6 m处的蓄水量(P<0.05),集水区内洼地的蓄水量大于坡面。(3)集水区内6个采样点浅层含水量随时间变化剧烈,深层含水量随时间变化小。(4)切沟对其上方集水区内土壤水分的水平影响距离为1~3 ...
