欢迎来到海南展馆 Welcome to the Hainan Pavilion
National Park of Hainan Tropical Rainforest, located in the central-south of Hainan Island, covers an area of 4,403 km2 (about 1/7 of Hainan Island). Within its scope are famous mountains such as Wuzhi Mountain, Yinggeling Ridge, Bawangling Mountain, Limu Mountain and Diaoluo Mountain, making it “the roof of Hainan”. It is also called the “water tower of Hainan”, for it contains the headwaters of major rivers like the Nandu River and Wanquan River.
National Park of Hainan Tropical Rainforest is one of the world’s 34 key biodiversity areas, and the only habitat of the Hainan gibbon. It has recorded 3,653 species of wild vascular plants (6 national level-one protected species and 419 Hainan endemic species) and 540 species of terrestrial vertebrates (15 national level-one protected species and 23 Hainan endemic species). Its biodiversity index is as high as 6.28, equal to Brazil’s Amazon rainforest.
Thanks to the construction of the pilot area of the National Park of Hainan Tropical Rainforest and other ecosystems with complex vertical structure are well-conserved, and the average canopy height is 46.8% higher than non-pilot areas. The overall forest area has increased and the ecosystem function has been further amplified. The coverage of suitable habitats in the pilot area has expanded and the quality improved. Nineteen new species have been discovered, and the number of important protected species grows steadily. The quality of the suitable habitats in the pilot area has significantly improved. Net primary productivity of the potentially suitable habitats for Hainan gibbons increased by 3.72%. The number of Hainan gibbon groups and individuals continue to grow steadily, with individuals reaching 35 and the fifth group steadily taking shape. Dipterocarpaceae plants—naturally distributed iconic tree species of rainforest—have been effectively protected. The population of Hopea hainanensis Merr. et Chun—a level-one protected plant—remains stable, with a growth-type age structure, suggesting further growth potential of the population.
