摘要
以常州市主城区为例,运用GIS技术对原始影像数据进行了解译、提取、运算和分析,对比了研究区的现状以及规划目标,得出常州市主城区人居环境生态适宜性模型(HI),并对人居生态环境适宜性进行了初步评价。结果表明:①常州市主城区人居生态环境适宜性介于2.05~10.35之间,整体生态适宜性较高,规划后生态适宜性提高。常州市主城区的低适宜和一般适宜居住区以带状分布为主,主要分布在工业集聚区、农业用地以及村庄分布区,现状占研究区总面积的68.91%;经规划后,低适宜和一般适宜居住区的面积明显减少83.32%;②常州市主城区的适宜和较高适宜居住区以片状分布为主,主要分布在高架环中部,以居住小区为主,现状占研究区总面积的30.31%;经规划后,适宜和较高适宜居住区面积明显提高57.90%;③从整体上看,沿南北中轴线分别向东、西两个方向,适宜性逐渐降低,规划后,整体适宜性明显提高,实现人与环境的协调发展。通过对常州市主城区人居环境生态适宜性评价,以期为该区域规划管理提供数据支撑。
Taking the main urban area of Changzhou City for example,GIS technology is used to interpret,extract,calculate and analyze the original image data.By comparing the current situation and planning objectives of the study area,the ecological suitability model(HI)of human settlements in the main urban area of Changzhou City was obtained.The suitability of ecological living environment was preliminarily evaluated.The results indicate that:①The ecological environment suitability of human settlements in the main urban area of Changzhou City ranges from 2.05 to 10.35,and the overall ecological suitability is high.The ecological suitability is improved after the planning.The low and general suitable residential areas in the main urban area of Changzhou City are mainly distributed in the belt,mainly in the industrial agglomeration area,agricultural land and village distribution area,accounting for 68.91%of the total area of the study area.After the planning,the area of low suitable and general suitable residential areas is significantly reduced by 83.32%;②The suitable and higher suitable residential areas in the main urban area of Changzhou City are mainly distributed in sheets,mainly in the middle of the elevated ring in residential areas,accounting for 30.31%of the total area of the study area;after planning,the area of suitable and high suitable residential area increased by 57.90%;③On the whole,along the north-south central axis,the suitability gradually decreased in the east and west directions.After the planning,the overall suitability is obviously improved,and the coordinated development of human and environment is realized.By evaluating the ecological suitability of human settlements in the main urban area of Changzhou City,this paper hopes to provide data support for regional planning and management.
