<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[World natural heritage sites are some of the most important and valuable protected areas in the world, and their designation aims to give recognition to the uniqueness and protect the integrity of the sites, which are ofglobal outstanding universal value. Understanding the global uniqueness and value of natural heritage will help to better manage and protect them, support the functioning of ecosystems, and promote sustainable development of humans and nature. A systematic review was conducted to determine the potential for the Hainan tropical rainforest to become a world natural heritage site. Based on a large number of literatures,we took the native plants, animals and vegetation communities of Hainan's potential natural world heritage site(Hainan Tropical Rainforest National Park)as the research objects, and evaluated the global outstanding universal value of Hainan's potential natural world heritage site from the aspects of biological ecological processes such as vegetation types, species diversity, fauna composition and endemic species. The results are as follows:(1)Hainan potential world natural heritage site has 3 653 vascular plant species. There are 540 species of terrestrial vertebrates, which account for 10%-30% of the wild animal species in the country. This indicates that biodiversity in this area is extremely high.(2)The flora found in the Hainan tropical rainforest is unique. Vegetation on Hainan Island can be categorized in the Indo-Malay rainforest group, and within the Malay region, and vegetation is tropical in nature and has a common origin with the South China mainland. This is indicative of the transition between the South China flora into the Asian rainforest.(3)The plant species specificity of flora is lower, there are only seven endemic genera in the flora, and about one out of every 10 species is endemic to the island. Lower specificity shows some characteristics of continental origin and the flora on the island are an irreplaceable element of biodiversity, and make up a valuable ecosystem. This study clarifies the outstanding universal values of the Hainan tropical rainforest and makes the case using empirical scientific evidence for nominating this area as a world natural heritage site.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Hainan Tropical Rainforest National Park is located in the middle mountainous region of Hainan Province, and it has a diverse landscape with 95.56% forest coverage. Studying the evolutionary aspects of the landscape pattern in time and space in Hainan Tropical Rainforest National Park is extremely important for preserving and enhancing Hainan Province's ecological security barrier. The landscape pattern index, single-motion landscape dynamic attitude and landscape transfer matrix were used to examine the geographical and temporal evolution features of the landscape pattern of 10 land cover patterns in Hainan Tropical Rainforest National Park between 2015 and 2020. This study used ground cover data from the Hainan Tropical Rainforest National Park between 2015 and 2020 to develop a landscape pattern distribution system based on actual ecological situations. Other elements that affected the evolution of the landscape pattern in Hainan Tropical Rainforest National Park included policies, climate and other natural and human factors. The results were as follows:(1)The overall landscape fragmentation of Hainan Tropical Rainforest National Park reduced from 2015 to 2020, increasing spatial agglomeration of the landscape, decreasing integrated dynamic attitude, and generally steady development of landscape patterns.(2)The area of evergreen broad-leaved forest in the tropical rainforest increased in five years, with an increase of 531.38 km<sup>2</sup>, a decrease in fragmentation, and a positive growth trend, and the landscape tends to be concentrated in patches; on the other hand, the area of needle-leaved forest and shrubwood significantly reduced, with losses of 189.53 km<sup>2</sup> and 294.74 km<sup>2</sup> respectively; there was also a partial transformation of water, and the area of the water landscape had been somewhat reduced, and the patches tended to be concentrated and spread; the remainder of the landscape patterns accounted for a relatively modest amount, and developed and changed in the direction of natural succession.(3)The landscape pattern evolution of Hainan Tropical Rainforest National Park was primarily based on natural succession of the rainforest, followed by a comprehensive impact of policy, climate and other factors, which reduced human factors on the tropical rainforest landscape interference and was conducive to improving the rainforest ecosystem's self-healing capacity. To summarize, the landscape pattern of Hainan Tropical Rainforest National Park has been stable since the commencement of the pilot project, and policy direction has played an essential constructive role. The targeted conservation and restoration of the tropical rainforest landscape will help to the Hainan Tropical Rainforest National Park's sustainable development.]]></description>
