中国科学院西北生态环境资源研究院敦煌戈壁荒漠研究站屈建军研究员带领团队在海南岛沿岸进行了长期的科学考察。考察过程中,他们在神州半岛、清水湾等地发现海岸鸣沙,并对新发现的海岸鸣沙和已发现的内陆沙漠鸣沙进行了对比和研究。

Chinese scientists have discovered an area of "singing sands" on the tropical island province of Hainan, the first time the strange auditory phenomenon has been identified on the country's coastline.
中国科学家在热带岛屿省份海南发现了一个“唱歌的沙子”区域,这是国内海岸线上首次发现这种奇怪的听觉现象。

Singing sands -- also known as rattling sands, whistling sands or musical sands -- consist of sandy areas of desert or coastline that naturally produce sounds in the wind due to a combination of physical characteristics, including the size and composition of the grains.
鸣沙——又称为响沙、哨沙或音乐沙—— 由沙漠或海岸线的沙地组成,由于物理特性的组合,包括颗粒的大小和成分,它们在风中自然产生声音。

According to the Northwest Institute of Eco-Environment and Resources (NIEER) under the Chinese Academy of Sciences, the discovery of singing sands on Hainan marks the first time that an area of Chinese coastline has displayed the phenomenon, and enhances the province's tourism potential.

据中国科学院西北生态环境资源研究院(NIEER)介绍,海南岛鸣沙的发现标志着中国海岸线区域首次出现这种现象,增强了该省的旅游潜力。

"The discovery of the magical natural phenomenon fills the gap of coastal singing sands in China. It will provide technical support to the development and protection of tourism resources in Hainan," said Qu Jianjun, an NIEER researcher and leader of the team that made the discovery.
“神奇自然现象的发现填补了我国沿海鸣沙的空白,将为海南旅游资源的开发和保护提供技术支撑。”NIEER研究员、团队负责人建军说。

Singing sands can be found at multiple inland sites within China, including the renowned Singing-sand Mountain, located near the Mogao Grottoes in the oasis city of Dunhuang, in northwest China's Gansu Province. Such sites provide a draw to visitors, keen to experience the strange phenomenon.
在中国的多个内陆地区都可以找到鸣沙,包括位于中国西北部甘肃省绿洲城市敦煌莫高窟附近著名的鸣沙山。这些景点吸引了热衷于体验这种奇怪现象的游客。

"The distribution of coastal singing sands is regarded as a reflection of quality beaches. It has long been assumed that there are no coastal singing sands in China, and our latest study provides a new answer," said Qu.
“沿海鸣沙的分布被认为是优质海滩的反映。长期以来,人们一直认为中国没有沿海鸣沙,而我们的最新研究提供了新的答案,”说。

The NIEER team discovered multiple singing-sand sites along the coasts of Clearwater Bay, Shenzhou Peninsula and other areas in Hainan.
NIEER团队在海南清水湾、神州半岛等沿海地区发现了多个鸣沙地

The study shows that the unique geomorphology and wave-breaking dynamics of these bays have shaped the well-sorted coastal sands in terms of grain size.
研究表明,这些海湾独特的地貌和破浪动力学塑造了粒度大小分类良好的沿海沙子。

The scientists investigated the characteristics of the coastal singing sands, such as the mineral composition, particle size, surface structure and acoustic characteristics, and compared them with those of singing sands in a desert region.
科学家们研究了沿海鸣沙的矿物成分、粒度、表面结构和声学特征等特征,并将其与沙漠地区的鸣沙进行了比较。

Their study shows that the surface of the coastal sands has typical V-shaped craters formed by underwater mechanical etching, and deep dissolution craters formed by chemical etching.
他们的研究表明,海岸沙地表层有典型的水下机械腐蚀形成的V形撞击坑和化学溶蚀作用而成的深邃溶蚀坑。

"This well-developed surface porous physical structure is an important factor in controlling the sound mechanism of the singing sands," said Qu.
“这种发达的表面多孔物理结构是控制鸣沙声机制的重要因素,”说。

However, the frequency spectrum of the coastal singing sands is narrower than that of the desert singing sands, with a high proportion of high-frequency components and a relatively sharp sound, according to the study.
但研究表明,沿鸣沙的频谱比沙漠歌沙的频谱窄,高频成分比例高,声音相对尖锐。

Qu said the discovery of the coastal sands in Hainan reflects the resort island's excellent seawater and beach quality, which are significant characteristics for the tourism resources of Hainan Province, thus generating significant economic, social and ecological benefits.
说,海南海岸沙滩的发现,反映了度假岛优良的海水和沙滩质量,是海南省旅游资源的显特征,可产生显着的经济、社会和生态效益。

"Further study regarding protection is needed," said Qu. "Meanwhile, it would be great to establish a coastal sand desert park, which could serve as a platform for scientific research and education.
"“需要进行进一步保护性研究,”说。“同时,建立一个滨海沙漠公园,作为一个科研教育平台,也是不错的选择。”
