Most landscape cover assessments for conservation programmes rely largely on remote sensing analyses. These analyses, however, neglect how people inhabiting protected zones perceive and structure land cover. Using socio‐ecological systems (SES) analysis in a forest‐savannah mosaic on the Congo Basin forest edge (Democratic Republic of Congo), we investigated how human practices, landscape perceptions and land use patterns affected forest cover. We conducted remote sensing analysis using a Sentinel‐2 satellite image and 187 GPS landmarks, producing a land cover map with 11 classes. Our results yielded an 81.85% correspondence with additional 164 GPS landmarks, a robust score in tropical areas. We conducted 40 individual interviews, eighteen focus group discussion workshops and nine months of participant observation of human practices to identify 19 land units and elaborate a granular SES system structuring the landscape. Integrating local knowledge and practices with general ecological and agronomic processes, we developed a landscape dynamics model revealing progressive forest colonisation of savannahs. Our methods demonstrate that a forest‐edge landscape cover evaluation through remote sensing and local knowledge can contribute to finer‐grained assessment of land cover and ecosystem services. This assessment can assist conservation efforts by considering local populations' practices on and perceptions of landscape change.

中非森林大草原马赛克景观动态的多维分析

大多数保护计划的景观覆盖评估都主要依赖于遥感分析。但是,这些分析忽略了居住在保护区的人们如何感知和构造土地覆被。在刚果盆地森林边缘(刚果民主共和国)的森林大草原马赛克中,使用社会生态系统(SES)分析,我们调查了人类实践,景观感知和土地利用方式如何影响森林覆盖。我们使用Sentinel-2卫星图像和187个GPS地标进行了遥感分析,生成了11类土地覆盖图。我们的结果得出了与其他164个GPS地标的81.85%对应,在热带地区得分很高。我们进行了40次个人访谈,18个焦点小组讨论会和9个月的参与者对人类实践的观察,以识别19个土地单位并精心构建构成景观的SES系统。将当地的知识和实践与一般的生态学和农艺学过程相结合,我们开发了一种景观动力学模型,揭示了大草原的渐进性森林定居。我们的方法表明,通过遥感和当地知识对森林边缘的景观覆盖度进行评估可以有助于更精细地评估土地覆盖率和生态系统服务。该评估可以通过考虑当地居民对景观变化的做法和看法来协助保护工作。将当地的知识和实践与一般的生态学和农艺学过程相结合,我们开发了一种景观动力学模型,揭示了大草原的渐进性森林定居。我们的方法表明,通过遥感和当地知识对森林边缘的景观覆盖度进行评估可以有助于更精细地评估土地覆盖率和生态系统服务。该评估可以通过考虑当地居民对景观变化的做法和看法来协助保护工作。将当地的知识和实践与一般的生态学和农艺学过程相结合,我们开发了一种景观动力学模型,揭示了大草原的渐进性森林定居。我们的方法表明,通过遥感和当地知识对森林边缘的景观覆盖度进行评估可以有助于更精细地评估土地覆盖率和生态系统服务。该评估可以通过考虑当地居民对景观变化的做法和看法来协助保护工作。
