摘要

[目的] 探究采煤沉陷区生态修复植物凋落物的分解特征及影响因素，为干旱气候条件下采煤沉陷区的生态修复提供理论依据。[方法] 采用野外分解袋试验的方法，选取沙柳(Salix psammophila)、小叶杨(Populus simonii)和沙柳与小叶杨混合凋落物3个处理，研究分析了在风沙土和黄土基质条件下，3种类型凋落物分解1 a后的残留量、有机碳(OC)、氮(N)、磷(P)、酸性洗涤纤维(ADF)和酸性洗涤木质素(ADL)的含量变化。[结果] ①沙柳凋落物年分解速率比小叶杨和混合凋落物高10%～15%；凋落物在黄土上的分解速率比在风沙土上的速率高13%～23%。②凋落物树种对凋落物OC，N和P含量有极显著(p＜0.01)影响，土壤类型对OC，N，P，ADF和ADL的含量均有显著(p＜0.05)或极显著(p＜0.01)影响，表明树种和分解土壤基质均是影响凋落物养分转化的重要因素。③不同凋落物处理之间，沙柳凋落物的OC，N含量高于混合和小叶杨，而沙柳凋落物的P含量在分解试验前4个月低于小叶杨和混合凋落物，随后接近该值。[结论] 相比沙柳，小叶杨凋落物分解较慢，在土壤上形成覆盖能够保持更长时，更适合作为内蒙古采煤沉陷区主要的修复植物。

Abstract

[Objective] The decomposition characteristics and influencing factors of plant litter for ecological restoration of a coal mining subsidence area were analyzed in order to provide a theoretical basis for restoration in an arid climate. [Methods] An one-year decomposition experiment that included three litter treatments (Salix psammophila; Populus simonii; 1∶5 ratio of S. psammophila∶P. simonii) and two decomposition soils (sandy soil

loess soil) was conducted in a coal mining subsidence area of Inner Mongolia using the field decomposition bag method. The residual dry mass and contents of organic carbon (OC)

nitrogen (N)

phosphorus (P)

acid detergent fiber (ADF)

and acid detergent lignin (ADL) of litter samples were determined once every two months. [Results] ① The decomposition rate of S. psammophila litter was significantly (p＜0.05) greater than the decomposition rates of P. simonii and the mixed treatment by 10%~15%. The litter decomposition rates in the loess area were significantly greater than in the sandy area by 13%~23%. ② The litter source had significant (p＜0.01) effects on OC

and P contents. Soil type had significant (p＜0.05 or p＜0.01) effects on OC

ADF

and ADL contents. Both tree species and soil type were important factors affecting the nutrient transformations of the litters. ③ The OC and N contents of S. psammophila litter were greater than those of P. simonii and the mixed litter. P content of P. simonii and the mixed litter were lower than the P content of S. psammophila litter during the first four months

and then the P contents of all of the treatments were similar. [Conclusion] P. simonii litter decomposed more slowly than S. psammophila litter

and therefore

can be maintained for a longer time on the surface of soil. Therefore

P. simonii is recommended to be used as a suitable restoration plant in the coal mining subsidence area of Inner Mongolia.
