Secondly, the rainwater is taken as an important component in a natural water circulation system, the water quality is stable, the pollution degree is light, the hardness is low, and the public acceptability of the purified rainwater is high. From the northeast to the southwest of China, coastlines are long, islands are numerous, tropical islands are dense and grouped, and the situations of uneven water resource distribution and water shortage still exist.
The Zhu island of south China sea and the sea area thereof are the largest sea area in five sea areas of China and are influenced by special soil matrix and hydrogeological conditions, the Zhu island of south China sea is mainly a coral reef island, the surface layer of the Zhu island of south China is a coral reef island and a biological debris sand layer which are formed late in the year, loose and unglued or weakly cemented, and coral reef limestone and coral shell meeting rock are arranged below the Zhu reef island and the coral shell meeting rock. The soil land has the structural characteristics of coarse quality, multiple pores and frangibility, surface runoff is difficult to generate by abundant rainfall on the island, and sandy soil is lack of natural organic matters, so that a sea island water and soil resource environmental system with structural water shortage, land impoverishment and ecological fragility is formed. At present, the fresh water supply of most islands in our country is mainly dependent on remote transport of water from the continent, desalination of sea water and rainwater collected and treated by hardened facilities.
Although the rainfall in the island and reef area of the south China sea is abundant, the conditions for developing and utilizing the rainwater resources are poor due to the conditions of special geological features and the like, so that the efficient collection and utilization of the rainwater resources in the island and reef area are promoted, and the method is particularly important.
