我们使用濒危兰花物种作为建立优先保护区的案例研究。我们对中国东北部的2,884个样地进行了详细的调查，选择了6个国家重点保护兰科植物(每个物种的样地数量为≥5)来规划保护这些濒危植物。首先，我们使用物种分布模型(在Maxent程序中)估计了6种兰花的潜在生境分布。其次，我们使用Maxent和系统保护规划软件(Zonation)的结果来确定PPA。我们发现，我们确定的PPA都分布在我们所关注的研究区域的东部、东北部和北部。我们观察到，这些地区现有的自然保护区比我们确定的PPA要小得多，这表明有必要扩大这些地带。最后，我们根据我们的PPA确定了一些建议的保护区，我们认为这些保护区是适合原址保护的区域。这些地区可以帮助制定保护这些濒危兰花物种的政策。我们的结果对保护生物学和重新定义濒危物种保护区具有广泛的意义。
We used endangered orchid species as a case study for establishing priority protected areas (PPAs). We conducted a detailed investigation of 2,884 plots in northeastern China and selected 6 nationally protected orchid species (the number of plots for each species ≥5) to plan PPAs in order to conserve these endangered plants. First, we estimated the potential habitat distributions of 6 orchid species using species distribution models (in the program Maxent). Second, we identified PPAs using the results of both Maxent and systematic conservation planning software (Zonation). We found that the PPAs we identified were all distributed in the eastern, northeastern, and northern parts of the study region on which we focused. We observed that existing nature reserves in those areas were much smaller than the PPAs we identified, suggesting the need for expansion of these zones. Finally, we identified some recommended protection areas based on our PPAs, which we believe are suitable areas of in situ conservation. These areas could assist in the formulation of protection policies for these endangered orchid species. Our results have broad implications for conservation biology and the redefinition of protective zones for at-risk species.
