基于GIS的城市景观聚集度空间分异研究——以大连市金普新区为例

Spatial Differentiation of Urban Landscape Aggregation Based on GIS——A Case Study on JinPu District

以大连市金普新区主城区2015年城市建筑数据为基础,利用城市景观二维聚集度指数,提出了城市景观三维聚集度指数,从多空间尺度,分析了城市景观聚集度的空间分异特征。研究结果表明,主城区景观聚集度指数分布呈现西南高东北低的趋势;景观聚集度大小与区域功能有关,工业区较低,居住区和商区较高,其中商居混合区出现最高值;大连民族大学、天成国际金融中心、安盛购物广场等附近空间格局呈较严重封闭状态,开发潜力较弱。

Based on 2015 building data of the main urban area of Jinpu New District in Dalian,this paper analyzes the spatial differentiation characteristics of urban landscape aggregation degree from multiple spatial scales by using two-dimensional urban landscape aggregation degree and putting forward three-dimensional urban landscape aggregation degree.The results show that the landscape aggregation index of Jinpu New Area presents a trend of high in southwest and low in northeast;the degree of landscape aggregation is related to regional function,the industrial area is lower,while the residential area and commercial area are higher,the highest value exists in the mixed area of commercial and residential areas;the spatial pattern of Dalian Minzu University,Tiancheng International Finance Centre,Ansheng Shopping Plaza and vicinityare in a serious closed state with weak development potential.
