土地利用/土地覆盖(LULC)与生态系统的完整性以及相关的供应、调节和文化生态系统服务(ES)密切相关。人类活动通过LULC的变化不断影响生态系统的完整性和ES。综合办法对于理解和衡量生态系统功能、相关的ES和不同系统组成部分的相对贡献之间的关系至关重要。在这里，使用当地合理的ES评分矩阵，我们将不同的LULC类型与孟加拉国拉瓦查拉国家公园的生态完整性和ES供应联系起来。这些结果被用来编制空间上明确的ES图。我们的分析表明，热带常绿混交林提供广泛的ES和支持生态完整性的能力相对较高，其次是茶园和橡胶种植园。位于公园边缘或外围的其他LULC类型的ES供应能力相对较低。我们的研究是在孟加拉国进行的第一次这类研究，可以被视为对可用的ES及其供应能力进行的第一次筛选研究。研究结果可为该地区基于ES的景观管理和未来的保护重点奠定基础。
Land uses/land covers (LULC) are closely related to the integrity of ecosystems and associated provisioning, regulating and cultural ecosystem services (ES). Anthropogenic activities continuously influence ecological integrity and ES through changes in LULC. An integrative approach is essential to understand and measure the relations between ecosystem functioning, associated ES and the relative contributions of the different system components. Here, using a locally justified ES scoring matrix, we linked different LULC types to ecological integrity and ES supply in the Lawachara National Park of Bangladesh. The results were used to compile spatially explicit ES maps. Our analysis revealed relatively high capacities of mixed tropical evergreen forests to supply a broad range of ES and to support ecological integrity, followed by tea (Camelliachinesis) gardens and rubber (Hevea brasiliensis) plantations. Other LULC types located on the edge or on the periphery of the park showed comparably lower ES supply capacities. Our study is the first of its type carried out in Bangladesh and can be seen as a first screening study of available ES and their supply capacities. The results can be used to form the base for ES based landscape management and future conservation priorities in the area.
