摘要
通过文献综述、综合分析和理论分析的方法对矿区所属的水土资源禀赋下矿山自然土壤特性和地域性矿区分布匹配进行了研究,总结出土壤地带性分布规律下的典型矿区所处的宏观条件,并在水土资源禀赋约束下提出了典型矿区土壤修复的主要约束限制因素。根据地带性土壤的不同把我国典型矿区划分为5种类型,分别是草原草甸矿区、高原黄土矿区、漫岗黑土矿区、平原棕-褐矿区、丘陵红壤矿区、高原草甸矿区。结果表明:不同土壤类型矿区下,土壤复垦具有其特有的限制因素与复垦修复重点和难点,草原草甸矿区的修复限制因素是表土资源修复,高原黄土矿区修复限制因素是水分重组,漫岗黑土矿区修复限制因素是土壤性状退化,平原棕-褐矿区修复限制因素是地面塌陷,丘陵红壤矿区修复限制因素是土壤重金属污染,高原漠土矿区修复限制因素是经济效益最大化。
The characteristics of the natural soil under the background of regional mining area and the distribution matching with the endowment of regional soil and water resources were studied by literature review,comprehensive analysis and theoretical analysis.The macro conditions of soil types,features and the geographical distribution in large scale were summarized,and the main constraint limiting factors of the land reclamation in mining area were put forward.According to the difference of zonal soil,Chinese mines are divided into 6 types including the grassland meadow mining soil area,plateau desert mining soil area,hilly black mining soil area,brunisolic-cinnamon mining soil area,hilly red earth mining soil area and plateau meadow mining soil area The results showed that under different type of soil mining area,there were unique constraints and difficulties in soil reclamation and repair.The limiting factor of the grassland meadow mining soil area was the surface soil resources.The limiting factor of the plateau desert mining soil area was the water restructuring.The limiting factor of hilly black mining soil area was the properties of the soil resource degradation.The limiting factor of the brunisolic and cinnamon mining soil area was the surface subsidence.The limiting factor of the hilly red earth mining soil area was the heavy metal pollution in soil,and the limiting factor of the plateau meadow mining soil area was the maximization of economic benefit.
