Plant species possess a huge potential in restoration of fly ash ecosystem. Litter deposition and its decomposition in the ash deposited sites are two important processes of the fly ash ecosystem. In order to identify the biological potential of a plant species to aid restoration of fly ash deposited sites, it is needed to assess leaf litter decomposition as well as nutrient release pattern. In the present investigation, we studied the leaf litter decomposition of the plant species (Leucaena leucocephala, Pithecellobium dolce and Prosopis juliflora) and mix plantation in the fly ash ecosystem. The litter bag experiment was conducted in the area of plantation on the fly ash deposited site during a period of 365 days. Percentage of C and N was higher in L. leucocephala > P. dolce >Mix Plantation > P. juliflora while C/N ratio was higher in P. juliflora >Mix Plantation > L. leucocephala > P. dolce. L. leucocephala and P. dolce showed relatively fast decomposition rates (k = 1.27, 1.17), respectively while mix plantation (k = 0.82) and P. juliflora (k = 0.73) exhibited relatively slower decomposition rates. Thus, we noted that the decomposition rate of L. leucocephala was greater than the other selected species. This shows that the species having faster decomposition rate and nutrient release could be a factual choice for rehabilitation of fly ash deposited sites.

植物物种在粉煤灰生态系统恢复方面具有巨大潜力。灰烬沉积地的凋落物沉积及其分解是飞灰生态系统的两个重要过程。为了确定植物物种的生物潜力以帮助恢复飞灰沉积地点，需要评估落叶分解和养分释放模式。在本次调查中，我们研究了飞灰生态系统中植物物种（ Leucaena leucocephala、Pithecellobium dolce和Prosopis juliflora ）的落叶分解和混合种植。垃圾袋试验在粉煤灰沉积地点的种植区进行，为期 365 天。C 和 N 的百分比在L. leucocephala  >  P. dolce  > Mix Plantation >  P. juliflora，而P. juliflora  > Mix Plantation >  L. leucocephala  >  P. dolce的 C/N 比较高。L. leucocephala和P. dolce分别表现出相对较快的分解速率 (k = 1.27, 1.17)，而混合种植 (k = 0.82) 和P. juliflora (k = 0.73) 表现出相对较慢的分解速率。因此，我们注意到L. leucocephala的分解速率大于其他选定的物种。这表明具有更快分解速度和养分释放的物种可能是粉煤灰沉积场地恢复的事实选择。
