The impacts of land-use change on ecosystem services (ESs) are currently a high profile issue, but the impacts of land-use configuration change on ESs have not been well studied so far. Taking the headwaters' region of the Dongjiang River (HRDR) as an example, the current study designed a specific framework for exploring the impacts of land-use configuration change on ESs independently. The Conversion of Land Use and its Effects at Small regional extent (CLUE-S) model was integrated with the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model to simulate water conservation services (WCS), nutrient retention services (NRS), and sediment retention services (SRS) in HRDR for nine planning scenarios. The main conclusions are: (1) land-use configuration change has significant impacts on the provision of WCS, NRS, and SRS; (2) mean patch area of landscape is the main factor affecting the provision of WCS, while mean slope of woodland is the main factor affecting the provision of NRS and SRS; and (3) none of the nine projected land-use configurations could simultaneously maximize the provision of WCS, NRS, and SRS; overall, the ninth land-use configuration was the optimal configuration. The current study bridges the gaps between land-use configuration change and the provision of ESs, and emphasizes the urgency of taking land-use configuration into consideration in future land-use planning to improve the provision of water-related ESs.

土地利用格局对与水有关的生态系统服务产生重大影响

土地利用变化对生态系统服务的影响目前是一个备受关注的问题,但到目前为止,土地利用结构变化对生态系统服务的影响尚未得到很好的研究。以东江源头地区(HRDR)为例,本研究设计了一个特定的框架,以独立探索土地利用结构变化对生态系统的影响。土地利用的转换及其在小区域范围内的影响(CLUE-S)模型与生态系统服务和折衷综合评估(InVEST)模型集成在一起,以模拟节水服务(WCS),养分保留服务(NRS) ,以及HRDR中的沉积物保留服务(SRS),可用于九种规划方案。主要结论是:(1)土地利用结构的变化对WCS,NRS和SRS的提供有重大影响;(2)景观平均斑块面积是影响WCS设置的主要因素,林地平均坡度是影响NRS和SRS设置的主要因素;(3)九种预计的土地利用配置中没有一个能够同时最大限度地提供WCS,NRS和SRS;总体而言,第九个土地利用配置是最佳配置。当前的研究弥合了土地利用结构变化和提供生态系统服务之间的差距,并强调了在未来的土地利用规划中考虑土地利用结构的必要性,以改善与水有关的生态系统的提供。(3)九种预计的土地利用配置中没有一个能够同时最大限度地提供WCS,NRS和SRS;总体而言,第九个土地利用配置是最佳配置。当前的研究弥合了土地利用结构变化和提供生态系统服务之间的差距,并强调了在未来的土地利用规划中考虑土地利用结构的必要性,以改善与水有关的生态系统的提供。(3)九种预计的土地利用配置中没有一个能够同时最大限度地提供WCS,NRS和SRS;总体而言,第九个土地利用配置是最佳配置。当前的研究弥合了土地利用结构变化和提供生态系统服务之间的差距,并强调了在未来的土地利用规划中考虑土地利用结构的必要性,以改善与水有关的生态系统的提供。
