海南岛为我国热带森林宝库,总面积5115万亩,森林资源丰富,有山地热带常绿林、沟谷热带雨林、山地雨林等,热带森林对保水蓄水、保土保肥起显著作用,它能充分发挥热带资源优势与生产潜力。但是,由于多年来的人为破坏,森林面积逐渐减小,经过30多年来的开发利用和乱砍滥伐,热带天然林由解放初期的1295万亩减少到360万亩,森林覆盖率仅剩7.2％,导致全岛生态失调和水土流失,这是值得注意的一个重大问题。
Hainan Island is a treasure trove of tropical forests in China with a total area of 51.11 million mu and abundant forest resources. There are mountainous tropical evergreen forests, valleys tropical rain forests, and mountain rain forests. Tropical forests play a significant role in preserving water and preserving soil. Give full play to tropical resources and production potential. However, as a result of years of vandalism, the forest area has been gradually reduced. After 30 years of development, utilization and deforestation, the number of tropical natural forests has dropped from 12.95 million mu in the early period of liberation to 3.6 million mu, with a forest cover rate of 7.2 %, Leading to the island’s ecological imbalance and soil erosion, which is a major issue worth noting.
