摘要

土地覆盖的变化会影响生态系统及其提供的服务。本研究旨在评估 1990 年至 2018 年期间立陶宛土地利用的空间变化，并分析生态系统服务价值（ESV）随景观结构变化而发生的变化。耕地提供了大部分生态系统服务价值，其次是森林、草地和湿地。2018 年，立陶宛的总 ESV 为 290 亿美元/年-1，土地利用对 ESV 有显著影响，1990 年至 2018 年间，ESV 共减少了 4.38 亿美元/年-1。ESV总变化主要受供给（4.26亿美元/年-1）和调节（2.08亿美元/年-1）服务减少的影响。耕地面积的减少是造成 ESV 损失的主要因素。生境和文化服务价值的增加不足以抵消 ESV 的减少。弹性最高的是城市，表明土地利用变化导致 ESV 发生了显著变化。这项研究的结果为生态系统的可持续管理和再生潜力提供了宝贵的见解。

Ecosystem Service Value Changes in Response to Land Use Dynamics in Lithuania

Changes in land cover affect ecosystems and the services they provide. The aim of this study was to assess the spatial changes in land use from 1990 to 2018 and analyze the changes in ecosystem service value (ESV) in response to the changes in landscape structure in Lithuania. Croplands provided the majority of the ESV, followed by forests, grasslands, and wetlands. The total ESV in Lithuania was USD 29 billion year−1 in 2018, and land use had a significant impact on ESV, with a total decrease of USD 438 million year−1 between 1990 and 2018. The total ESV change was mainly influenced by the decrease in provisioning (USD 426 million year−1) and regulating (USD 208 million year−1) services. The reduction in cropland area was a major factor in the loss of ESV. The increase in the value of habitat and cultural services was not large enough to offset the reduction of the ESV. The highest elasticities were in the urban municipalities, indicating a significant change in ESV due to land use change. The results of this study provide valuable insight into the potential of the sustainable management and regeneration of ecosystems.
