摘要:
 “三生空间”是主体功能区战略实施及国土空间保护新格局构建的重要基础，对所属区域国土空间结构优化具有重要意义。以贵阳市花溪区为研究对象，通过ENVI对研究区1999、2003、2007、2011、2019年5期遥感影像进行解译，基于“三生空间”理论，运用空间分析、转移矩阵、动态度、标准差椭圆、景观格局指数法，构建区域空间模型，探究研究区“三生空间”时空变化、梯度分布、景观格局演变特征及演变方向。结果表明，1)花溪区“三生空间”分布受自然地理因素影响差异显著，生产生活空间主要集聚于西部丘陵及中部槽谷盆地，生态空间主要散布于北部以及西南部山地；2)演变方向以“西北—东南”为主轴发生不同角度倾斜；3)低海拔和缓坡区“三生空间”类型多样、异质性强，生态空间向高海拔及高坡度区有一定扩展；4)花溪区“三生空间”整体破碎化，由单一规则型向混合复杂型转变，连通性减弱，空间异质性增强。通过分析“三生空间”景观格局内在机制，以期为喀斯特地区国土空间结构优化，推进“三生空间”协调发展提供一定科学参考。
Abstract:
 Production-Living-Ecological Space (PLES) is an important foundation for the strategy implementation of functional zones and a new pattern of territorial protection,and is of great significance for optimizing territorial spatial structure.Taking Huaxi District of Guiyang City as an case study,five periods of remote sensing images of 1999,2003,2007,2011 and 2019 were visually interpreted by ENVI,and based on the PLES theory,the spatial analysis,transfer matrix,dynamic degree,standard deviation ellipse and landscape pattern index were used to construct the regional spatial model and explore the spatial-temporal evolution,gradient distribution,landscape pattern evolution characteristics and direction of the PLES in the study area.The results showed that 1) there was a great diversity which influenced by natural geographical factors of the PLES of Huaxi District.The production-living space was mainly concentrated in the western hills and central trough basins,and the ecological space was scattered in the northern and southwestern mountains.2) The center of evolution change was tilted at different angles among the "northwest-southeast" direction.3) The types of territorial space exhibited diverse and strong heterogeneity in low altitude and gentle slope areas,and ecological space expanded to high altitude and high slope areas to a certain extent.4) The PLES was generally fragmented in Huaxi District,changed from single regularization to mixed and complex type,the connectivity weakened and the spatial heterogeneity enhanced.Through the analysis of the internal mechanism of the landscape pattern of the PLES,it is expected to provide some scientific references for optimizing the land spatial structure and promoting the coordinated development of the PLES in karst area.
