Name origin: It's said that the trees were very luxuriant in DiaoLuo Shan in ancient times. However, the local people burned the mountains to grow grains and recklessly utilized the forest resources, irritating the god. Then the god ordered not to locally offer any rainfall for three years as a punishment. As a result, the ground was baked, the crops were withered, and ordinary persons lived miserably. In order to save the fellow villagers, Nanxi, a brave and industrious young man from Miao Nationality, passed through all trials and finally climbed to the top of Sanjiao Shan at the height of 1,499 meters. He threw himself upon his knees for seven days and nights in exchange for the sacred gong that might summon rain from the god. "Xiaomei", the daughter of the god, was moved by the righteousness and complete sincerity of Nanxi, took the sacred gong from the god by strategy, descended to the world and hung the sacred gong in the highest tree in the stockaded village together with Nanxi, and beat the gong to summon rain. Afterward, wind and rain have come on time year after year, and the ground has recovered as beautiful as before. That's why it is called DiaoLuo Shan. There are also many places named in connection with this myth of ecological civilization, such as Nanxi River, Xiaomei Reservoir, Seven Fairies Waterfall, and the Sisters Waterfall.

Typical landscapes and features: DiaoLuo Shan is one of China's significant tropical rainforest distribution areas. It is one of China's rarest tropical forest ecological system types, and also a typical representative of China's tropical rainforest. In the park, there are many unique tropical rainforest landscapes, such as "Hanging Garden", "Standing Plate-shaped Roots", "The Root Embracing the Rock", "Old Stem with Flowers", "Single Tree Forming a Forest", "Regeneration of Fall Tree", "Dripping Tip" and "Strangling Plants", etc. The climate there is very pleasant, and the content of negative ions reaches 125,000 nos. / m3 at most, which ranks the top one among all identical forests in China. It is the genuine "Natural Air Anion Bar". It has won honors like "China's Forest Oxygen Bar". It is also the sunstroke prevention, health & wellness, and leisure resort in Hainan Province, and one of the best resorts at the latitude of 18°N. This area features great rainfall, abundant water resources, and greater elevation difference, as there is s a great number of valleys and waterfalls and beautiful and unique water scenery. Due to its unique location in the National Park of Hainan Tropical Rainforest, DiaoLuo Shan has "The Greatest Waterfall in Hainan" (i.e. FengGuo Shan Waterfall), as well as the Internet celebrity waterfalls (i.e. Dali Waterfall and Shiqing Waterfall) and more than 100 other unknown small and large waterfalls.

Geological landform: DiaoLuo Shan stands in the east of Jianfeng - DiaoLuo Deep Major Fracture, and to Wanning - Maling Anticline in the northwest and Kenglong Fracture in the southeast. Generally, DiaoLuo Shan has a middle mountain terrain. The dominant elevation is above 500 meters. There are some low hills around the park. The wider intermountain basins, waterfalls and reservoirs are distributed among the hills in the middle. The rocks are mainly classified into two categories, namely, granite and mixed granite.
Soil: There are many soil-forming rocks in DiaoLuo Shan, mainly including the biotite-granite, granite-porphyry and mixed granitoid. Subject to comprehensive conditions such as rock type, climate, altitude and geographical location, the main soil types there are mountainous yellow soil and mountainous lateritic red soil.
Climate: DiaoLuo Shan enjoys a tropical marine monsoon climate and thus has abundant rainfall. The annual rainfall there is between 1,870mm and 2,760mm and may be above 2,850mm at most. There is also abundant sunlight and heat, with total radiation of 460 J/cm2 and an average annual sunshine duration of 1,676 - 2,150 hours.
