摘　　要：人类活动已成为影响保护区生态状况的重要因素。当前研究主要集中在保护区内人类活动的整体监测,然而,关于农业活动单方面影响的研究仍不足。因此,选取山东荣成大天鹅国家级自然保护区为研究区,利用耕地变化遥感数据集,基于内外对比法、土地转移矩阵和人类活动干扰指数法,研究该保护区在限制耕地扩张方面的保护成效。结果表明:(1)现状:2020年保护区内的耕地面积占保护区总面积的26.93%,主要分布在中部地区,即缓冲区的边界和实验区的主体区域;(2)时空动态格局:保护区内的耕地面积在1980—2020年间总体呈下降趋势,主要分布在核心区和缓冲区,实验区内的耕地整体呈增加趋势;(3)保护成效:1980—2020年间保护区的内部耕地面积总体增速小于外部,表明保护区的保护成效相对较好;(4)耕地影响强度评价:保护区内农业活动的影响强度自1980年至2020年间呈下降趋势,表明保护区在限制耕地扩张方面具有有效性。研究结果可为自然保护区的监测和管理提供科学支撑。Human activities have become a significant factor affecting the ecological status of protected areas(PAs).Current research mainly focuses on the overall monitoring of human activities within PAs,but studies on the specific impact of agricultural activities remain insufficient.This paper selected the Shandong Rongcheng Whooper Swan National Nature Reserve as the study area,and utilized remote sensing datasets of cropland change to examine the effectiveness of the reserve′s effectiveness at resisting the pressure of cropland expansion.This study employed methods such as inside⁃outside comparison,land utilization transition matrix,and the human activity interference index.The results indicate that:(1)Current Status:In 2020,cropland within the reserve accounted for 26.93%of the total area,primarily distributed in the central region,i.e.,the boundary of the buffer zone and the main area of the experimental zone.(2)Temporal⁃Spatial Dynamics:From 1980 to 2020,the cropland area in the reserve showed a general decreasing trend,mainly in the core and buffer zones,while cropland in the experimental zone showed an overall increasing trend.(3)Conservation Effectiveness:Between 1980 and 2020,the growth rate of cropland area inside the reserve was lower than that outside,indicating relatively better conservation effectiveness.(4)Impact Intensity Evaluation:The human activity interference index within the reserve showed a decreasing trend from 1980 to 2020,demonstrating the reserve′s effectiveness at resisting the pressure of cropland expansion.This study′s findings can provide scientific support for the monitoring and management of nature reserves.
