评价土地利用变化对生态系统服务功能的影响是支持土地利用管理和环境保护政策制定的有效方法。利用灰色预测模型对太原市2014 - 2020年土地利用变化进行预测,并建立线性规划模型,优化2020年土地利用结构,实现生态系统服务价值最大化。然后比较了政府土地利用规划与优化土地利用结构的差异,并评价了两者对环境价值的影响。结果表明,2014 - 2020年,林地和建设用地面积将持续增长,耕地、果园、草地和水体面积将持续减少。政府土地利用规划总生态价值为1548295万元,优化土地利用结构总生态价值为1557024万元,增加8729万元。RMB.in此外,与政府土地利用规划相比,优化土地利用结构后,除粮食生产和原材料外,其他生态系统服务功能的ESV均有不同程度的增加。这说明优化后的土地利用结构是一种有效的土地利用方案,值得管理者和决策者考虑和参考。for.land此外,本案例研究也可为中国其他城市的城市发展提供有价值的参考。DOI:10.1061/.(ASCE)UP.1943-5444.0000447。© 2018美国土木工程师协会。
Evaluating the variations of ecosystem services in response to land-use change is recognized as an effective method in supporting.policy making involved in land-use management and environment protection. Using the gray forecasting models, this study predicts the landuse.change from 2014 to 2020 in Taiyuan, China, and establishes a linear programming model to optimize the land-use structure for 2020 to.maximize the total ecosystem services value (ESV). Then the study compares the difference between the government’s land-use planning and.the optimized land-use structure and evaluates their effects on ESV. The results show that the areas of woodland and built-up land will keep.growing from 2014 to 2020, whereas cropland, orchard, grassland, and water body will decrease continuously. The total ESV is.15,482.95 million renminbi (RMB; the official currency of China) in the government’s land-use planning and 15,570.24 million RMB.in optimized land-use structure, an increase of 87.29 million RMB. Moreover, compared with the government’s land-use planning, the.ESV of all ecosystem services, except food production and raw materials, have varying degrees of increase in optimized land-use structure..These demonstrate that the optimized land-use structure is an effective land-use scheme that is worthy of consideration and is a reference for.land managers and policy makers. In addition, this case study may provide valuable information to other cities in China. DOI: 10.1061/.(ASCE)UP.1943-5444.0000447. © 2018 American Society of Civil Engineers.
