摘要
以瑞丽市为研究区,分别构建乡镇尺度下的三生功能评价指标体系和栅格尺度下的空间适宜度体系,基于尺度传递效应,利用乡镇三生功能评价结果修正栅格空间适宜度结果,借助ArcGIS 10.7软件中的Python语言构建循环算法,比较图斑适宜度大小从而识别三生空间。研究结果表明:(1)瑞丽市生产功能主要分布在农业生产、交通、口岸和仓储等功能突出的区域;生活功能高值区主要体现在农村居民点和建制镇并与生产功能具有空间一致性;生态功能突出,主要分布在林地和水域等生态用地占比大的乡镇。(2)瑞丽市生产适宜度空间分异特征明显,呈南北强中间弱分布;生活空间适宜性格局与生产空间具有明显一致性;生态适宜度与生产、生活适宜度表现出显著的空间互补性。(3)瑞丽市三生空间以生态空间为主,生产、生活空间布局与对外贸易表现出明显的正相关。
Ruili City was taken as the research area in this study. The evaluation index system of production-livingecological function at the township scale and the spatial suitability evaluation index system at the raster scale were constructed respectively, and the evaluation results of production-living-ecological functions at the township scale were used to correct the result of the raster spatial suitability based on the scale transfer effect. With the help of the Python language in ArcGIS 10.7 version, a loop algorithm was constructed by comparing the suitability of the selected grid, so as to identify and delineate the status quo of production-living-ecological space. The results show that:(1) The production function of Ruili City is mainly distributed in areas with prominent functions such as agricultural production, transportation, ports and storage. The high-value areas of living function are mainly distributed in rural residential areas and towns in dots or lumps. At the same time, the living function and production function have obvious spatial consistency. The ecological function is prominent and mainly distributed in towns with a large proportion of ecological land such as woodland and water.(2) The spatial diversity of production suitability in Ruili City is obvious, with a strong north-south and weak middle distribution. The spatial suitability pattern of living space is obviously consistent with that of production space. The ecological suitability, production and living suitability show significant spatial complementarity.(3) The production-living-ecological space types in Ruili City are mainly ecological space, and the layout of production and living space shows a significant positive correlation with foreign trade.
