山区和教科文组织的山区生物圈保护区包含了广阔的海拔范围，涵盖了地质、地形和气候多样性的大梯度，因此比周围的低地拥有更大的生物多样性。MBR中生物丰富性的大部分结果来自于气候差异和沿沿着海拔梯度的重力的相互作用。外部力量，如大气变化和人类土地利用与这些梯度相互作用，并导致独特的景观斑块，即镶嵌的土地覆盖类型内和跨海拔带。生物多样性和生态系统的管理影响到土地利用和土地覆盖，从而影响到生物多样性和生态系统进程，而生物多样性和生态系统进程都为社会提供货物和服务。由于其广泛的环境和生物多样性，MBR非常适合全球变化研究，并将在说明生物多样性保护方面越来越重要。本文总结了一个关于海拔梯度的国际研讨会的生态相关成果，该研讨会旨在综合海拔背景下的主要生态系统和生物多样性条件及驱动因素。讲习班为生物多样性审查制定了一个核心研究议程，优先考虑长期研究和广泛海拔范围内土地利用的变化。
Mountain regions and UNESCO Mountain Biosphere Reserves (MBRs) encapsulate broad elevational ranges, cover large gradients of geological, topographical and climatic diversity, and thus host greater biodiversity than the surrounding lowlands. Much of the biological richness in MBRs results from the interaction of climatic contrasts and gravitational forces along elevational gradients. External forces such as atmospheric change and human land use interact with these gradients, and result in distinct landscape patchiness, ie mosaics of land cover types within and across elevational belts. The management of MBRs influences land use and land cover, which affects biodiversity and ecosystem processes, both of which provide goods and services to society. Due to their broad environmental and biological diversity, MBRs are ideally suited for global change research and will be increasingly important in illustrating biodiversity conservation. This article summarizes the ecologically relevant results of an international workshop on elevational gradients that aimed to achieve a synthesis of the major ecosystem and biodiversity conditions and drivers in an altitude context. The workshop developed a core research agenda for MBRs that prioritizes long-term research and changes in land use across a broad elevational range.
