Abstract

Objective: To analyze land use patterns in the Environmental Protection Area (APA) of Ibirapuitã (Rio Grande do Sul, RS) and surrounding municipalities between 1985 and 2022. Theoretical framework: Although the South Brazilian Pampa biome is traditionally associated with low-impact agriculture, there is a recent advance in the conversion of natural vegetation in areas of remnants of native fields such as southwestern RS. This region is home to the Ibirapuitã APA, the largest conservation unit in the Pampa biome in RS (more than 300,000 ha). Methods: Based on land use maps obtained from the MapBiomas platform, the areas of each land use class were extracted and quantified using geoprocessing techniques. We then compared the annual trajectories of land use classes in the internal perimeter of the APA and the surrounding area using descriptive statistics. Results: During the analyzed period, the areas of natural land use classes (native grassland and forest) remained stable within the APA, while in the surrounding municipalities the areas of native grasslands were markedly reduced and mostly replaced by agriculture and urbanization. Implications: The Ibirapuitã APA proved to be strategic for the conservation of native fields in this region of the southern Brazilian Pampas. Novelty: By comparing land use trajectories in the internal perimeter and surroundings of the conservation unit, this study provides the first assessment of the effectiveness of the Ibirapuitã APA in maintaining the natural vegetation of the South-Brazilian Pampa biome.

潘帕草原关键区域的环境变化:Ibirapuitã环境保护区(南里奥格兰德州)及其周边地区土地利用的定量分析
目的:分析1985 - 2022年Ibirapuitã(里约热内卢Grande do Sul, RS)及周边直辖市环境保护区(APA)土地利用格局。理论框架:尽管巴西南部潘帕生物群落传统上与低影响农业有关,但最近在原生农田残余地区(如巴西西南部)的自然植被转化方面取得了进展。该地区是巴西最大的潘帕生物群落保护单位Ibirapuitã APA的所在地(超过30万公顷)。方法:基于MapBiomas平台获取的土地利用图,利用地理处理技术提取并量化各土地利用类别的面积。然后,我们使用描述性统计比较了APA内部周长和周边地区土地利用类别的年度轨迹。结果:在分析期内,APA内自然土地利用类型(天然草地和森林)的面积保持稳定,而周边直辖市的天然草地面积明显减少,大部分被农业和城市化所取代。启示:Ibirapuitã APA被证明对巴西南部潘帕斯草原的原生农田保护具有战略意义。新颖性:通过比较保护单元内部周边和周围的土地利用轨迹,本研究首次评估了Ibirapuitã APA在维持巴西南部潘帕草原生物群落自然植被方面的有效性。
