安徽省大方寺省级自然保护区人类活动遥感监测

Remote sensing monitoring of human activities in DaFangSi Provincial Nature Reserves,Anhui Province

遥感监测是自然保护地监管的重要技术手段。本文以大方寺省级自然保护区为例,选用2018—2022年多期卫星影像进行遥感监测,提取人类活动信息,并进行影响评估。研究表明,2018—2022年,大方寺自然保护区人类活动类型中农田面积最大,养殖和居民点等人类活动逐步减少;保护区内人类活动影响程度逐步减小,实验区影响程度大于缓冲区大于核心区。大方寺自然保护区受人类活动影响程度较小,但仍需严格控制旅游开发,加强林地保护。

Remote sensing monitoring is an important technical means of conservation area supervision.Taking Dafangsi Provincial Nature Reserve as an example,this paper used multi-period satellite images from 2018 to 2022 to conduct remote sensing monitoring,extract human activity information,and conduct the impact assessment.The study showed that from 2018 to 2022,the area of agricultural land was the largest among the human activities in Dafangsi Nature Reserve,and the areas of human activities such as farming and residential areas gradually decreased.The influence degree of human activities in the protected area gradually decreased,and the influence degree of the experimental area was greater than that of the buffer area and greater than that of the core area.Dafangsi Nature Reserve was less affected by human activities,but tourism development should be strictly controlled and forest land protection should be strengthened.
