不同覆盖物对水体蒸发及藻类繁殖的影响研究

Effect of Different Mulch Materials on Water Evaporation and Algae Propagation

为研究覆盖物对水体水分蒸发和藻类繁殖的影响,通过室外模拟实验,研究了苯板、黑色橡胶球、黑色防水布、透明塑料布等覆盖材料对水体蒸发和藻类繁殖的抑制作用。结果表明,覆盖物对水体具有抑制蒸发作用,抑制结果依次为:苯板>黑色防水布≈透明塑料布>黑色橡胶球;覆盖物对藻类繁殖也有抑制作用,抑制结果依次为:苯板>黑色防水布>透明塑料布>黑色橡胶球。结论表明,黑色防水布是水体防蒸发和抑制藻类繁殖的优选材料。

In order to investigate the effect of different mulch materials on water evaporation and algae propagation, inhibition effects of different mulch materials including polystyrene plate, black rubber ball, black waterproof cloth and transparent plastic cloth on water evaporation and algae propagation were studied. The results show that the mulch materials have inhibition effects on water evaporation, the inhibition effect order of different mulch materials is as followed： polystyrene plate black waterproof cloth ≈transparent plastic cloth black rubber ball; the mulch materials also have inhibition effects on algae propagation, the inhibition effect order is as follows： polystyrene plate black waterproof cloth transparent plastic cloth black rubber ball. The conclusion illustrates that the black waterproof cloth is one of the best materials for preventing water evaporation and inhibiting algae reproduction.
