摘要

由于自然和人为过程,保护区随着时间的推移而发生变化,导致生物多样性和生态系统服务的丧失。由于目前和预计的气候趋势将给保护区的可持续性带来压力,对现有扰动的分析对于提供有助于保护管理的有价值的见解至关重要。利用1997年、2008年和2018年的Landsat数据,采用模糊k均值无监督分类方法,对马拉维卡松古国家公园(面积2445.10 km2)的土地覆盖变化、景观特征和植被强度时空格局进行了评价。研究结果显示,从1997年到2018年,森林覆盖率损失了21.12%,平均每年损失1.09%。土地覆被变化的过渡分析表明,森林向灌木转化是土地覆被转变的主要形式,20 a间灌木和裸地向森林转化的比例相对较低(分别为3.51%和3.48%),表明森林更新率很低。公园内剩余的森林覆盖聚集在一个小的土地面积内,具有不同的景观特征。2018年植被强度和活力较低,主要集中在公园东部。这些发现对气候变化背景下的保护管理和森林依赖地区对生态系统服务的需求不断增长具有重要意义。

Spatial and Temporal Change of Land Cover in Protected Areas in Malawi: Implications for Conservation Management
Protected areas (PAs) transform over time due to natural and anthropogenic processes, resulting in the loss of biodiversity and ecosystem services. As current and projected climatic trends are poised to pressurize the sustainability of PAs, analyses of the existing perturbations are crucial for providing valuable insights that will facilitate conservation management. In this study, land cover change, landscape characteristics, and spatiotemporal patterns of the vegetation intensity in the Kasungu National Park (area = 2445.10 km2) in Malawi were assessed using Landsat data (1997, 2008 and 2018) in a Fuzzy K-Means unsupervised classification. The findings reveal that a 21.12% forest cover loss occurred from 1997 to 2018: an average annual loss of 1.09%. Transition analyses of the land cover changes revealed that forest to shrubs conversion was the main form of land cover transition, while conversions from shrubs (3.51%) and bare land (3.48%) to forest over the two decades were comparatively lower, signifying a very low rate of forest regeneration. The remaining forest cover in the park was aggregated in a small land area with dissimilar landscape characteristics. Vegetation intensity and vigor were lower mainly in the eastern part of the park in 2018. The findings have implications for conservation management in the context of climate change and the growing demand for ecosystem services in forest-dependent localities.
