摘要: 以新疆麦盖提县为研究区域,根据土地利用主导功能完成麦盖提县3类国土空间分类与布局分析,通过单一动态度指数、洛伦兹曲线、基尼系数与景观格局指数从时空尺度分析其动态变化特征。结果表明,农业空间占县域国土空间最大比例且面积逐年递增、分布绝对均匀,景观斑块类型紧凑度高、多样性丰富、优势度凸显;2009—2019年城镇空间面积增长3倍,以麦盖提镇为中心城区集聚分布、各个乡镇散落分布,基尼系数递减,城镇空间集中扩张促进分布格局趋于均衡化;生态空间转化为城镇空间与农业空间,面积逐年减少、景观连续性与优势度随着斑块面积减少而降低。

Abstract: Based on the dominant function of land use, the spatial classification and distribution of three types of land space in Makit County, Xinjiang, were analyzed. The dynamic characteristics of the three types of land space in Makit County were analyzed from the spatio-temporal scale by single dynamic attitude index, Lorentz curve, Gini coefficient and landscape pattern index. The results showed that the agricultural space occupied the largest proportion of the county's land space, the area was increasing year by year, and the distribution was absolutely uniform. The landscape patch type was highly compact, the diversity was rich and the dominance was prominent. From 2009 to 2019, the urban space area increased by 3 times. With Maigaiti Town as the central urban area, it gathered and distributed, and each township was scattered. Gini coefficient decreased, and the centralized expansion of urban space promoted the distribution pattern to be balanced. The ecological space was transformed into urban space and agricultural space, and the area decreased year by year, while the landscape continuity and dominance decreased with the patch area decreased.

Key words: three types of land space, spatial dynamic change, landscape pattern, arid area in northwest China, Makit County
