Invasive plants are often found with high soil N content because of the fast-decaying litter production [48], which may affect the activity of soil microbial community, providing favorable environment to them [59, 69], such as increase in soil tempera-

Nitrous oxide is a major GHG which contributes to the depletion of ozone layer and is released from soils [90]. It has been widely linked to soil microbial activity [12]. Soil biota can be affected through litter and rhizosphere inputs of invasive plant species and may stimulate nutrient release via litter effect. Furthermore, invasive plants support more decomposers [22] and can modify soil enzyme activity [91], as well as fast-decaying litter from the invasive species [48], land-use legacy and many other factors alter soil microbial communities [23], further accelerate N cycling and increasing N2O emissions altering the atmosphere composition [24]. The emission of N2O to the atmosphere further facilitating global warming is expected to change the geographic ranges of some invasive species [26, 92], creating new opportunity for the establishment and development of introduced species, and can also affect the phenology of invasive species [93]. We define that more N concentration causes more N2O emission. Hall et al. [16] show that canopy N concentration has effects on N2O emission where the canopy concentration of invasive species was higher than that of native plants, especially in the summer season, and vary between forest types. By comparison remote estimates of canopy N in either season did not properly predict N2O emission in the dry forest ecosystems. However invasive *Morella faya* increased N2O emission in dry and wet forest ecosystem but the effects was most significant when the forest canopy dominated by Morella faya individual and with few other plant species in the overstory or understory. In addition, an increase in the soil pH and abundance of nosZ and nirK genes results in decreasing N2O emission [94].

Plant invasion alters ecosystem service which results to huge economic loss and ecological loss worldwide. There are many factors behind the invasive plant success.
