摘　　要：以西安市为例,从土壤保持功能、水源涵养功能、生物多样性保护功能和水土流失敏感性4个方面进行了生态保护评价,基于FLUS模型和西安市2010、2018年土地利用数据对2035年建设用地空间格局进行了模拟。结果表明:(1)西安市生态系统功能重要性整体属于中等重要,水土流失敏感性以轻度敏感为主。(2)使用驱动因子模拟2018年土地利用空间格局,总体精度达到85.82%,Kappa系数为82.98%。(3)通过模拟2035年建设用地发现,变化最大的是临潼区、灞桥区和阎良区,周至县变化最小。Xi’an City was taken as an example.The ecological protection evaluation was conducted from four aspects:soil conservation function,water conservation function,biodiversity protection function and soil erosion sensitivity in this paper.Based on the FLUS model and land use data of Xi’an in 2010 and 2018,the land space pattern in 2035 was simulated.The results show that the importance of ecosystem functions in Xi’an is of medium importance as a whole,and the sensitivity to soil erosion is mainly mild.The driving factors were used to simulate the spatial pattern of land use in 2018,the overall accuracy reached 85.82%,and the kappa coefficient was 82.98%.By simulating the construction land in 2035,it is found that the biggest changes are mainly in Lintong,Baqiao and Yanliang,and Zhouzhi has the smallest change.
