森林损失会对生态系统服务造成严重破坏，特别是在热带地区。热带森林在中国西南地区分布广泛，并不断受到人类活动（如橡胶繁荣）的影响。然而，森林对土地规划的模拟还没有系统地进行。基于未来土地利用模拟模型，分析了西双版纳2000年土壤保持、水分、碳固定和生境质量4个ES的时空特征，并对自然开发、橡胶开发和生态保护3个情景进行了设计和评价。结果表明：(1)2000 - 2020年，土壤保持量平均下降449.1 t，产水量平均下降13.4 mm，生境质量平均下降0.1 mm，固碳平均下降0.1 kg C/m2；(2)除产水量外，4种ESs之间存在协同关系，且在协同关系的边缘存在权衡；(3)与自然开发和橡胶开发情景相比，环境保护情景在保护自然保护区和减少破碎化方面具有更高的效率；(4)土地利用变化强度会加速生态环境承载力的减少，自然保护区和西部边界北部地区应提高环境保护水平。该工作不仅从生态环境和土地规划的角度进一步丰富了生态系统研究，而且为生态系统和森林情景提供了不同的规划视角。这对于有条不紊地处理森林可持续性问题是有用的。
Forest losses can lead to severe damage to ecosystem services (ESs), especially in the tropics. Tropical forests are widespread in southwestern China, and they experience continual effects of human activities (e.g., rubber boom). However, forest simulations of land planning have not yet been systematically conducted. Based on a future land-use simulation model, here, the spatio-temporal characteristics of four ES (i.e., soil retention, water yield, carbon fixation, and habitat quality) were examined, and three scenarios (i.e., natural development, rubber development, and ecological protection) were designed and evaluated during 2000 for Xishuangbanna (XSBN), southwestern China. The results showed that: (1) from 2000 to 2020, the average values of the ESs declined by 449.1 t for soil retention, 13.4 mm for water yield, 0.1 for habitat quality, and 0.1 kg C/m2for carbon fixation; (2) the four ESs, with the exception of water yield, had synergistic relationships, and trade-off appeared on the margins of these synergistic relationships; (3) compared with the scenarios of natural development and rubber development, the environmental protection scenario was found to have high efficiency for protecting nature reserves and reducing fragmentation; and (4) the intensity of land-use change will accelerate the decrease of ESs, and it is essential for nature reserves and areas of northern XSBN to improve their level of environmental protection. This work not only further enriches the ES research from the ecological environment and land-planning points of view, but it also provides different planning perspectives for ES and forest scenarios. This is useful in methodical approaches to forest sustainability.
