摘　　要：本文利用Arc GIS影像处理软件和Fragstats景观指数计算软件,采用空间影像数字化的方式,探究昭阳区城区土地利用现状及各绿地景观类型分布特征。结果表明,昭阳区城区耕地面积为88.24 hm^(2),占研究区总面积的51.00%,位于十一类土地利用类型第一位;昭阳区旧城南部区域各用地类型总体分布均衡,稳定性较好,整体优于新城北部;研究区绿地主要分布在郊区及近郊区,城区中心出现绿地空洞,绿地整体蔓延趋势呈现由中心圆辐射城区四周,建议城区在加大城市化扩张的同时提高城市新区绿地面积与质量。This paper uses ArcGIS software to explore the spatial characteristics and image distribution of green space in Zhaoyang City,and uses Fragstats software to calculate the landscape indices of each urban area.The results show that the cultivated land area of Zhaoyang District is 88.24 hm^(2),accounting for 51.00%of the total area of the study area,ranking first among the eleven land use types;the land types in the south of the old city of Zhaoyang District are generally evenly distributed and stable,which is better than that in the north of the new city as a whole;the green space in the study area is mainly distributed in the suburbs and suburban areas.There is a green space void in the urban center,and the overall spread trend of the green space radiates around the urban area from the central circle.It is suggested that the urban area should increase the urbanization expansion and improve the green space area and quality of the new urban area.
