摘  要:
区域土地利用演变是一个复杂的多因素综合作用下的非线性变化过程,通过土地利用变化模型去深入理解这种演变过程、特点以及未来变化趋势是一种有效的技术手段.以典型干旱区绿洲-博斯腾湖流域为研究区,运用CLUE-S模型,并结合Logistic回归分析、情景分析等方法,模拟了博斯腾湖流域2030年不同情景方案下的土地利用空间分布格局.结果表明:(1)以2010年土地利用数据为基准模拟的2015年土地利用格局,模拟正确比例为91. 05%,Kappa指数为0. 895,模拟效果良好,表明CLUE-S模型在博斯腾湖流域具有良好的土地利用变化模拟能力.(2)在不同模拟情景方案下,城建用地和耕地面积都将持续增长,新增城建用地和耕地主要是在现有基础上向外延伸;草地面积也有一定程度的增加,但增速明显放缓;林地和水域面积将继续萎缩.3种情景方案下的研究区土地利用空间分布格局存在较大差异.该研究可为博斯腾湖流域土地资源合理配置及生态保护提供理论参考.

摘  要:
The evolution of regional land use is a complex,multi-factor and non-linear process.It is an effective technical way to deeply understand the evolution process,characteristics and future trend of land use change through land use change models.Taking the typical arid oasis—Boston Lake Basin as the study area,based on CLUE-S model,combined with logistic regression analysis,scenario analysis and other methods,the spatial distribution pattern of land use under different scenarios in Boston Lake Basin in 2030 was simulated.The results show that:(1) Based on the 2010 land use data,the land use pattern in 2015 is simulated,the correct ratio is 91. 05%,and the Kappa index is 0. 895.The simulation effect is good,which shows that CLUE-S model has good ability to simulate land use change in Boston Lake Basin.(2) Under different scenarios,the urban construction land and cultivated land area will continue to grow.The newly added urban construction land and cultivated land will mainly extend outward on the existing basis.The grassland area has also increased to some extent,but the growth rate has slowed down significantly.The area of forest land and waters will continue to shrink.There are significant differences in the spatial distribution pattern of land use in the study area under the three scenarios.This study can provide a theoretical reference for the rational allocation of land resources and ecological protection in the Bosten Lake Basin.
