摘要： 以甘肃省土地开发强度与土地供给能力的协调关系为研究对象，运用指数计算模型、协调度模型和R/S分析方法研究了2001—2016年甘肃省土地利用空间协调度时空格局分异及态势，以期对国土开发利用、社会经济、资源环境相互协调推进提供参考依据。结果表明：（1） 甘肃省土地开发强度呈现上升趋势，土地供给能力变化幅度较小，基本保持在0.4左右。（2） 土地利用空间协调度时间上呈现上升—下降趋势，空间上呈现从河西走廊地区向陇东、陇南地区递增的空间格局，且河西地区土地利用空间协调状态不稳定，协调等级较低。（3） 各地区土地利用空间协调度的Hurst指数均大于0.5，在未来一段时间内土地利用空间协调度仍然会以延续过去变化态势为主，其中张掖市具有较强持续性，而其余地区持续性相对较弱。整体上，甘肃省土地利用空间协调度时空分异特征仍十分明显。为了满足将来土地开发利用的需求，各市州要明确发展定位，在资源环境约束下合理调控土地开发利用强度。

Abstract: Taking the harmonious relationship between the land development intensity and land supply capacity in Gansu Province, China as the research object, the spatial-temporal pattern differentiation and the situation of spatial coordination degree of land use of Gansu Province from 2001 to 2016 were studied in order to provide reference frame to the coordinated promotion of land development and utilization, social economy and resources and environment. The index calculation model, coordination degree model and R/S analysis method were used in this study. The results showed as follows: (1) The land development intensity of Gansu Province shows an upward trend, and the change range of land supply capacity is small which is basically kept at around 0.4. (2) The spatial coordination degree of land use shows a rise and then decline trend from time perspective, and there is an increasing spatial distribution from the Hexi Corridor to the eastern and southern Gansu Province. Moreover, the spatial coordination degree of land use in Hexi region is unstable and the coordination level is low. (3) The Hurst index of spatial coordination degree of land use in all regions is greater than 0.5.In the future, the spatial coordination degree of land use will continue with the change patterns in the past. Among them, the sustainability is stronger in Zhangye City but relatively weak in other regions. On the whole, the spatial-temporal differentiation of spatial coordination degree of land use in Gansu Province is still obvious. It is necessary to clarify the development orientation of the cities in order to meet the needs of land development and utilization in the future, and to control the intensity of land use development under the constraints of resources and environment.

Key words: land development intensity, land supply capability, spatial coordination degree, spatial-temporal differentiation, Gansu Province
