| Abstract: | Ecological water requirement is focused on by many researchers in the circumstance of long term water resources deficiency,especially in non-regional vegetation type of forest land.In this paper,Penman method is used to calculate ecological water quota and ecological water requirement in the investigated area of Haitan Island.The result shows that the ecological water requirement is 0.03004-0.05004 billions m3,and ecological water quota is between 374 and 623 mm.By this calculation,the paper can provide scientific reference for the status of ecological water deficiency in Haitan Island and sustainable management in forest land ecological system. |
