摘要:

在生态优先导向下协调干旱区国土空间开发与保护格局,对促进区域可持续发展具有重要意义。以新疆阿克苏地区为研究对象,通过分析2013—2023年“生产-生活-生态”空间转换矩阵以评估时空演变,并综合运用最小累积阻力(MCR)模型,提取生态与开发源地、构建综合阻力面、计算最小累积阻力差值,并引入突变检测法确定分区阈值,最终划定国土空间功能区,据此提出差异化优化策略。结果表明:(1) 2013—2023年阿克苏地区生产空间净增788.80 km2,生活空间净增189.28 km2,生态空间缩减978.08 km2,空间格局呈生态主导、生产扩张、生活缓增的态势。(2) 以最小累积阻力差值为0划分国土空间开发适宜性,其中开发建设适宜区面积为1.63×104 km2,在阿克苏地区中部呈现东、西、南3个聚类;生态保护适宜面积为1.15×105 km2,呈包裹状分布于开发建设适宜区的外围。(3) 根据最小累积阻力差值与栅格数目的关系曲线临界点-36040、-8820、0、9630将阿克苏地区国土空间开发功能区划分为生态保护区、农业生产区、开发建设区、保护生产区、生产开发区,面积分别为54456.73 km2、18763.61 km2、2305.15 km2、41924.40 km2、13990.09 km2,确立了3个强属性功能区和2个复合型功能区。(4) 以功能区为依托,在市县尺度上将阿克苏地区聚类为3个差异化发展集群:城市发展空间、智产融合空间、绿优兴农空间,其优势功能分别为开发建设、生产开发、保护生产,据此提出阿克苏地区国土空间开发的差异化优化策略。

Abstract:

Guided by ecological priority, the coordination of the development and protection patterns of territorial space in arid regions is greatly important for promoting regional sustainable development. Taking Aksu Prefecture in Xinjiang of China as the study area, we assessed spatiotemporal evolution by analyzing the transformation matrix of production-living-ecological spaces from 2013 to 2023. The minimum cumulative resistance (MCR) model was used to extract ecological and development sources, construct a comprehensive resistance surface, and calculate the difference in MCR. Catastrophe detection was introduced to determine zoning thresholds, delineating territorial spatial functional zones and accordingly proposing differentiated optimization strategies. The results show that (1) From 2013 to 2023, production space in Aksu Prefecture increased by a net area of 788.80 km2, living space increased by 189.28 km2, and ecological space decreased by 978.08 km2. This spatial pattern is characterized by ecological dominance, production expansion, and the slow growth of living space. (2) Taking the difference in MCR of 0 as the threshold, territorial spatial development suitability was divided. The most suitable area for construction and development covered 1.63×104 km2, appearing in terms of three clusters (east, west, and south) across the central part of Aksu Prefecture. The most suitable area for ecological protection makes up 1.15×105 km2, which is distributed peripherally in an enclosing pattern around the suitable area for construction and development. (3) Based on the critical points (-36040, -8820, 0, and 9630) of the relationship curve in the difference in MCR and the number of raster cells, the territorial spatial development functional zones of Aksu Prefecture were divided into ecological protection, agricultural production, construction and development, protection and production, and production and development zones, with areas of 54456.73 km2, 18763.61 km2, 2305.15 km2, 41924.40 km2, and 13990.09 km2, respectively, establishing three strong-attribute functional zones and two composite functional ones. (4) According to the functional zones, at the city-county level, Aksu Prefecture is clustered into three differentiated development clusters: an urban development space, a smart-industry integration space, and a green-agriculture optimization space, and the dominant functions of these are construction and development, production and development, and protection and production, respectively. Thus, differentiated optimization strategies for territorial spatial development are proposed for Aksu Prefecture.
