摘要: 为全面了解不同植被恢复模式对铁尾矿物种多样性及土壤理化性质的影响,在唐山迁安选取基于造地工程的植被恢复模式(紫穗槐林)、基于水保工程的植被恢复模式(六孔砖模式)、灌木纯林植被直接恢复模式(沙地柏直接造林模式)、乔木混交林植被直接恢复模式(沙棘-桑树混交直接造林模式),对其物种组成、数量特征和土壤理化性质进行调查,并与裸尾矿和未被破坏的天然灌丛进行对比分析.结果表明:(1)不同植被恢复模式的物种α多样性指数的变化趋势基本相同,丰富度指数和多样性指数均为沙棘-桑树乔木混交林>紫穗槐林>沙地柏灌木纯林>六孔砖;(2)与裸尾矿相比,沙棘-桑树乔木混交林模式、紫穗槐林模式及沙地柏灌木纯林模式下的土壤容重分别减少了6%,15%,14%,总孔隙度分别增加了16%,1%,8%,毛管孔隙度分别减少了19%,16%,4%,非毛管孔隙度分别增加了118%,46%,22%;沙棘-桑树乔木混交林模式、紫穗槐林模式下的土壤毛管持水量分别减少了18%,7%,而沙地柏灌木纯林恢复模式下的土壤毛管持水量增加了21%;(3)通过植被恢复后,相对于裸尾矿土壤,沙棘-桑树乔木混交林模式、紫穗槐林模式和沙地柏灌木纯林模式下的土壤有机质、速效钾含量明显...
英文摘要: In order to understand the effect of different vegetation restoration measures(four different vegetation recoveries,including vegetation restoration based on building soil engineering,water conservation projects with through-hole brick,direct restoration with sabina,mixed forest with seabuckthorn and mulberry) on the species diversity of iron tailings,species composition,quantitative characteristics and soil properties were investigated and compared with bare tailings and natural bush).The results showed th...
