摘要
海南岛是我国仅次于台湾的第二大岛,占我国5×10~4km^2热带面积的7.0%左右,具有得天独厚的光、热等资源。解放三十多年来,海南岛的建设取得了不少成绩,但在开发过程中,也造成一定程度的失误,生态平衡出现某种程度的破坏。随着海南岛的建省,办大特区。
Destructions of forest and biological resources, water resource and soil resource on Hainan Island are analyzed in relation to its population, resources and development. Long-term forest destruction,slash-and-burn cultivation and other unreasonable land uses are considered to be the main causes of the ecological destruction. 8 dominant factors are selected and fuzzy cluster method is used for the grade classification of ecological destruction on Hainan Island. It is showed that ecological destructions of 28% counties are serious and 40% counties are above medium. Some suggestions about the ecological environmental protection on Hainan Island are proposed on the above bases.
