<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Guizhou Province is rich in ecological resources, and the establishment of national park is conducive to centralized and standardized management of ecological resources. In order to analyze the spatial distribution characteristics of national nature reserves in Guizhou Province, and to screen out the advantageous landscape resource gathering areas for the selection of national parks, we analyzed the spatial distribution characteristics of 113 protected areas in five categories by ArcGis spatial analysis tool, and screened out the candidate areas of national park pilots and evaluated their resources. The results are as follows:(1)The national nature reserves in Guizhou Province are distributed in a cohesive way with a high degree of overlap, and eight national park pilot candidate areas are delimited by taking the reserve gathering area as the landscape advantage area.(2)Based on the analysis of the main representative resources of the gathering areas and the experts'scores, the concentration areas with higher scores can be recommended as the national park pilot areas, and the highest score in Chishui-Xishui area can be selected as the national park experimental area.(3)The national representativeness, suitability, state-owned and social feasibility of Chishui-Xishui area resources can meet the basic principle of setting up national parks with priority to integrate the overlapping protected areas, and its plant diversity conservation is of great value. The results of this study provide a new idea for choosing location of national parks and a reference for the establishment of national parks based on nature reserve system and the conservation of plant diversity in national parks.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To grasp the current status of orchid diversity in main land nature reserves in Hainan and the key habitat factor restricting their development, conducted an investigation of orchid resource in the study area and analyzed the spatial distribution pattern of orchid diversity, the canonical correspondence analysis(CCA)was used to explore the influence of habitat factors on the composition of orchid, and finally the negative binomial regression under the framework of generalized linear model(GLM)was used to fit the response of the richness and abundance of orchid to habitat variation. The results are as follows:(1)A total of 193 species in 67 genera of orchids are found in the study area, which is the absolute center of the distribution of orchid in Hainan.(2)In the horizontal direction, Bawangling has high richness of orchid but relatively crowded population, while the largest elevation difference in Wuzhishan brings more diversified niche types and wide living spaces, giving birth to a rich and even distribution of orchid.(3)In the vertical direction, orchids are the most rich in mid-elevation area and the inter-species competition is fierce, while high-elevation area have obvious dominant groups.(4)The elevation factor has a very high explanatory rate for the variation of orchid composition, and the significant influence of karst and river valley landform can also not be ignored.(5)The comprehensive effect of multiple factors affects the diversity of orchid, among them, the significant positive effect of slope, valley landform, and karst landform and the significant negative effect of <i>Liquidambar formosana</i> forest are less affected by other covariate, which is the key habitat factor that drives change in the richness and abundance of orchid. In summary, middle and high elevation areas and special landforms(such as river valley and karst)should be considered as priority protection area for orchid diversity.]]></description>
