Properties of ecological environment damage and their mechanism of restoration in arid and semi-arid coal mining area of western China [PDF]

open access: yes
The focus of coal development in China has been strategically shifted westward. That realize green mining of coal resources and coordinated ecological development becomes one of the important measures to ensure national energy security.

三峡库区主要森林植被类型土壤渗透性能研究

open access: yesShuitu Baochi Xuebao, 2007
对三峡库区11种主要森林植被类型114块临时样地土壤渗透指标及物理性质进行测定和比较。结果表明:(1)各森林植被类型林地A层土壤渗透速率和孔隙度均高于B层,土壤渗透速率与土壤孔隙度之间存在显著相关关系。(2)不同森林植被类型林地各层次土壤稳渗速率存在差异。常绿阔叶林地各层土壤的稳渗速率最高,A、B层分别达到8.72 mm/min,8.52 mm/min,其后依次为杉木林、针叶混交林等,马尾松林最低,A、B层分别仅为2.22 mm/min和1.13 mm/min。(3 ...

石质山地不同条件的土壤入渗特性研究

open access: yesShuitu Baochi Xuebao, 2002
通过对影响土壤渗透的多个因素的测定,研究了石质山地不同土壤不同层次的渗透能力,不同水温对渗透的影响,渗透筒不同插入深度对渗透的影响,由此可以得出,土壤的渗透能力是由各立地条件的土壤理化性质决定的。影响土壤入渗性能的最主要因素是土壤的总孔隙度和非毛管孔隙,这与土壤容重和土壤含水量也有很大关系。入渗与水温表现为较好的线性关系。
