摘要: 为了协调经济发展、耕地保护与生态保护,以新疆和田地区为研究区域,基于1990—2020年土地利用数据,选取自然、社会和经济方面共12个驱动因子,设置经济发展、耕地保护和生态保护3种情景,运用PLUS模型模拟2050年土地利用状况。结果表明,1990—2020年,研究区以未利用地为主,未利用地、耕地、建设用地及草地面积呈增加趋势,水域和林地面积大幅减少。以2010年为基期,利用PLUS模型预测2020年土地利用状况,与实际数据对比检验,结果显示模型总体精度为0.987,Kappa系数为0.971,模拟效果良好。多情景模拟显示,在耕地保护情景下,耕地面积增加最多,但林地和草地面积减少,导致水土保持、水源涵养等服务功能下降;在经济发展情景下,建设用地大幅扩张;在生态保护情景下,耕地保护力度相对有限但总量得到保障,有效减缓了对生态用地的占用。综合比较,生态保护情景更契合研究区未来可持续发展方向。

Abstract: In order to coordinate economic development, cultivated land protection and ecological protection, the Hotan Prefecture in Xinjiang was taken as the research area. Based on the land use data from 1990 to 2020, 12 driving factors in natural, social and economic aspects, and three scenarios of economic development, cultivated land protection and ecological protection were set to simulate the land use status in 2050 by the PLUS model. The results showed that from 1990 to 2020, the study area was dominated by unused land. The area of unused land, cultivated land, construction land and grassland showed an increasing trend, while the area of water and forest land decreased significantly. Taking 2010 as the base period, the PLUS model was used to predict the land use status in 2020, and the results were compared with the actual data. The results showed that the overall accuracy of the model was 0.987, the Kappa coefficient was 0.971, and the simulation effect was good. Multi-scenario simulations showed that under the cultivated land protection scenario, the area of cultivated land increased the most, but the area of forestland and grassland decreased, resulting in the decline of ecosystem services such as soil and water conservation and water retention. Under the economic development scenario, construction land expanded substantially. Under the ecological protection scenario, the intensity of cultivated land protection was relatively moderate, but the total amount was guaranteed, which effectively slowed down the occupation of ecological land. Through comprehensive comparison, the ecological protection scenario was more consistent with the future sustainable development direction of the study area.

Key words: land use change, multi-scenario simulation, PLUS model, Hotan Prefecture
