摘要
人类活动对自然保护区的生物多样性和生态平衡有潜在的重要影响,定量评价人类活动干扰对保护区的保护与管理具有重要意义。本文基于多源遥感数据,结合社会、经济、外业调查数据,利用熵值法和“N-E-S”(自然(Nature)、经济(Economy)、社会(Social))模型,构建了自然保护区人类活动干扰评价指标体系,开展了海南青皮林省级自然保护区人类活动干扰强度评价分析。2017—2020年间,青皮林保护区及不同实验区范围内,林地面积减少幅度最大,且距离保护区越远,面积减少幅度越大;人类活动干扰主要来自旅游、农业用地、居民点用地等开发活动频繁的东部地区,在保护区内部以及不同范围实验区内,人类活动干扰强度以低等级为主,保护区内部干扰强度稍有增加,0—3 km实验区范围内干扰强度下降,3—6 km范围内干扰强度增加最多。本文研究结果可为省级保护区的进一步督察提供可靠的信息来源,为省级自然保护区后续管理政策的制定提供信息支撑。
Human activities have potentially important impacts on the biodiversity and ecological balance of nature reserves,and it is important to quantitatively evaluate human activities interference on the conservation and management of reserves.In this paper,based on multi-source remote sensing data,combined with social,economic and external survey data,the entropy value method and the“N-E-S”(Nature,Economy and Society)model were used to construct an index system for evaluating human activity interference in na-ture reserves and carry out the analysis of human activity interference intensity in Hainan Pi-viridis Lin.Between 2017 and 2020,the largest decrease in forest area was observed in the Pi-viridis Lin reserve and different experimental areas,and the farther away from the reserve,the larger the decrease in area was;Human activities interference mainly came from the eastern area with frequent devel-opment activities such as tourism,agricultural land and residential land,and within the reserve and different experimental areas.The intensity of human activity disturbance is mainly of low level within the protected area and within the experimental areas of different ranges,and the intensity of disturbance increases slightly within the protected area,decreases within the range of 0-3 km experimen-tal area,and increases most within the range of 3-6 km.The results of this study can provide a reliable source of information for fur-ther inspectors of provincial protected areas,and provide information support for the formulation of subsequent management policies of provincial nature reserves.
