Quantifying Study on the Adaptive Ability of Mangrove to Their Oxygen Deficiency Habitat

In this paper, the adaptive ability of five major mangrove plants grown in Qinglan Harbour, Hainan Province are analysed comprehensively by grey clustering analysis method through measuring their relative indexes of adaptive organs. It has been pointed out that the distribution positions of these five species are closely related with their ability and expounded that inundated height of mangrove plants is an important factor which impels them to produce and develop their adaptive organs to the oxygen deficiency.
