钱江源国家公园体制试点区功能分区对黑麂保护的有效性评估

功能分区是统一协调国家公园不同保护管理目标的主要措施, 对于国家公园的有效管理有重要意义。钱江源国家公园是我国首批国家公园体制试点区之一, 被分为核心保护区、生态保育区、游憩展示区和传统利用区4个部分, 对应不同的保护管理措施。本研究分析了钱江源国家公园体制试点区现有功能分区与其首要保护对象黑麂(Muntiacus crinifrons)的适宜栖息地之间的空间关系。在红外相机调查获取的94个黑麂分布点的基础上, 结合海拔、地形、植被特征、人为活动干扰等15个环境特征变量, 采用MaxEnt模型预测国家公园内黑麂适宜栖息地的空间分布。结果表明, 黑麂倾向于出现在森林较为原始和道路密度较低的区域, 其适宜栖息地面积42.5 km ², 占国家公园总面积的16.9%。其中, 69.3%的黑麂适宜栖息地位于核心保护区, 30.4%位于生态保育区, 表明国家公园现有功能分区能很好地满足黑麂栖息地保护的需求。此结果也证明黑麂可以作为其分布范围内保存较好的亚热带森林生态系统的指示性物种。通过生境恢复、廊道建设和跨省共建促进黑麂栖息地的完整性保护, 是加强该区域黑麂栖息地保护的关键措施。

Evaluating the effectiveness of functional zones for black muntjac (Muntiacus crinifrons) protection in Qianjiangyuan National Park pilot site

Functional zoning is a method of classifying areas to define human use and is of great significance for the effective management of protected areas. Qianjiangyuan National Park is one of the ten national park pilot sites in China and is divided into four functional zones, the core protection zone, ecological conservation zone, recreation zone and traditional utilization zone. Each zone is assigned a different level of protection and corresponding management measures. This study examined the spatial overlap of existing functional zones in Qianjiangyuan and suitable habitats for its target conservation species, the endangered black muntjac (Muntiacus crinifrons). We constructed distribution models based on 94 occurrence locations obtained from camera-trapping surveys from 2014-2018 using MaxEnt. Fifteen covariates related to altitude, topography, vegetative characteristics and human disturbance were used in the MaxEnt models to predict suitable habitats for the black muntjac. The results showed that the black muntjac tended to inhabit areas with intact forest and low road density. We identified 42.5 km ² of suitable habitat, which accounted for 16.9% of the land in Qianjiangyuan National Park. Of this suitable habitat, 69.3% and 30.4% were located in the core protection zone and ecological conservation zone, respectively, which indicated that the existing zone designations can protect black muntjac habitat appropriately. These results also indicated that the black muntjac may serve as an indicator species of the subtropical primary forests where it lives. Promoting habitat integrity for the black muntjac by restoring habitat, constructing corridors and managing across provinces will be key to strengthening the protection of the black muntjac in the region.
