快速城市化加剧了中国土地利用方式的转变，耕地减少，土地开发增加，影响了生态系统服务价值，导致环境恶化。为改善生态环境质量，中国启动了生态文明建设战略，并尝试建立生态补偿机制。以江苏省为例，将线性优化模型与小区域土地利用转换及其效应（CLUE-S）模型相结合，对江苏省2025年土地利用变化进行优化和定量模拟，以最大化土地利用转换和土地利用价值损失。结果表明，2000 - 2015年，江苏省共有17.76%的土地被转换，造成了5.76 × 1010 yuan. yr-1 ESV的总损失。但是，我们预测2025年土地利用总面积将比2015年增加0.4%，这将导致ESV增加3.79 × 1010yuan.yr-1。耕地和草地减少最多，林地、水域和湿地增加。此外，空间模拟结果还表明，2025年，环太湖地区、苏中与北方交界地区以及北方内陆地区将经历土地利用转型带来的生态系统价值变化。我们还讨论了土地利用和生态保护政策。模拟结果为江苏省各子区域生态补偿机制的实施提供了潜在的有效指导。
Rapid urbanization intensifies land-use transition by shrinking cropland and increasing the land development of land in China, which affects the ecosystem services value (ESV) and causes environmental degradation. To improve the quality of the ecological environment, China has launched a strategy for the construction of an ecological civilization and attempted to build an ecological compensation mechanism. In this study, combining linear optimization model with the conversion of land use and its effects at small regional extent (CLUE-S) model to optimize and quantitatively to simulate land-use change based on embedding to maximize the ESV for land use planning in 2025 in Jiangsu province, a Chinese province that has experienced the greatest land-use transition and ESV loss in China. The results showed that a total loss of 5.76 × 1010yuan.yr−1ESV from 2000 to 2015 was due to the conversion of a total of 17.76% of the land in Jiangsu. However, we predicted that the total area of land use will increase by 0.4% in 2025 compared to that in 2015, which will lead to an increase of the ESV by 3.79 × 1010yuan.yr−1. Cropland and grassland will decrease the most, while woodland, water area and wetland will increase. Moreover, our spatial simulation showed that the regions around the Taihu Lake, the boundary between central and northern Jiangsu, and the inland region of northern Jiangsu will experience great ESV change caused by land-use transition in 2025. We also discussed land use and ecological protection policies. Our simulation results provide a potentially effective guide for implementing ecological compensation mechanisms among sub-regions in Jiangsu province.
