| 總結: | (_Wetlands are the Il1{)st productive ecosystem on earth. For generations, it plays an
important role by perfonning certain functions. One of the functions of wetlands is act as a
wastewater treatment facility with the present of plants. The survey conducted has shown
that there are significant water quality changes as the wastewater flow through the wetland
and there is five dominance plants species (Ipomea aquatica. Leersia hendra, &leria sumatrensis, Mikania micrantha and Commelina nudijlora) in UNIMAS cleared Peatswamp Forest. Out of these five dominance plant species, statistic indicated four of them are correlated higher with water quality parameters.) Those four plants are Ipomea aquatica, Leersia hendra, &leria sumatrensis and Mikani6 micrantha. &leria sumatrensis correlated highly with pH (r -0.681), ammonia-nitrogen (r '= 0529), nitrate (r '= -0.415) and chemical oxygen demand (r 0.621). Ipomea aquatica is correlated with pH (r = 0.414) and
ammonia-nitrogen (r -0.417). While the Leersia hendra and Mikania micrantha are only correlated with biochemical oxygen demand and dissolved oxygen respectively. However,
only Ipomea aquatica, &leria sematrensis and Leersia hendra are recommended plants in consl.lucted wetlands based on the high index from correlation analysis with water quality. |
