Since the national park system was piloted in 2019, Hainan has made great efforts to build a new model of intelligent ecological management and protection. Hainan Rainforest National Park Administration has built a provincial-level smart management center and a smart rainforest big data center platform, and carried out "electronic fence" construction pilot projects in Bawangling, Diaoluoshan and Wuzhishan, and started the "sky-land" integrated monitoring system project of Hainan Rainforest National Park, exploring the construction of a four-in-one tropical rainforest monitoring system of "forest dynamic monitoring sample plot+satellite sample plot+random sample plot+kilometer grid sample plot".
On the monitoring screen of Jianfengling Branch of Hainan Tropical Rainforest National Park Administration, the video can be switched to multi-angle high-definition images at any time, and live broadcast can be realized by connecting with the camera installed in the rainforest.
The forest coverage rate of Jianfengling area is over 97%, which is rich in biological resources and is one of the hot spots of biodiversity in the world. "Through ‘ Electronic fence ’ And multi-functional monitoring system, we have greatly reduced the number of people entering the mountains and found many species that have not been seen for a long time. " Yang Shibin, deputy director of Jianfengling Branch of Hainan Tropical Rainforest National Park Administration, said.
In addition to ecological protection and resource monitoring, scientific and technological means are also applied to the daily patrol and maintenance of Hainan tropical rain forest.

In Bawangling area, the information-based patrol management platform is connected with the special mobile phone equipped by rangers, which can check their patrol time and route in real time, and realize standardized and information-based management of patrol work. The application of science and technology, such as fire remote video monitoring watchtower and fire video monitoring command center, has improved the ability of forest protection and fire prevention.
"From the older generation of scientists ‘ Measurement on foot ’ , until now ‘ Sky land ’ Integrated and comprehensive monitoring, Hainan Tropical Rainforest National Park has initially established a long-term positioning monitoring system for natural resources and biodiversity, and through it, it has carried out the protection and management of tropical rainforest ecosystems, key species habitats and ecological environment, as well as biodiversity and forest carbon sinks. Scientific research. " Wang Nan, deputy director of Hainan Rainforest National Park Administration, said, "In addition, a series of other scientific and technological means are also helping the effective management and protection of Hainan Rainforest."
