【摘要】：以郑州市域为研究范围,通过Arc GIS 10.2和ENVI 5.0等遥感软件,对1992、2000、2004、2009和2013年的Landsat TM遥感影像和DEM高程影像进行解译,获取郑州市域城乡景观空间分布和地形高程数字化信息,并通过GIS空间分析和Fragstats 4.2软件,分析过去20年间郑州市域城乡景观格局在不同地形区位上的时空演变特征。结果表明,平原黄泛沙区(海拔6.0~135.2 m)和丘陵黄土沟壑区(海拔135.2~315.4 m)分别占研究区域总面积的50%和24%,是城市、农田和水体空间的主要分布区域,也是人类活动的主要集聚区;浅山区(海拔315.4~495.6 m)和深山区(海拔495.6~1 459 m)分别占研究区域总面积的19%和7%,是绿地空间的主要分布区,也是风景名胜区集聚区和生态环境保护的重要区域。
[Abstract]:Taking Zhengzhou as the research area, the remote sensing images of Landsat TM and DEM height of 1992 / 2000/ 20042009 and 2013 were interpreted through remote sensing software such as Arc GIS 10.2 and ENVI 5.0, and the spatial distribution of urban and rural landscape and the digital information of topographic elevation in Zhengzhou were obtained. Through GIS spatial analysis and Fragstats 4.2 software, the spatial and temporal evolution characteristics of urban and rural landscape pattern in Zhengzhou during the past 20 years were analyzed. The results show that the Yellow River sandy area (6.0m above sea level) and the hilly loess gully region (135.2k315.4 m above sea level) account for 50% and 24% of the total area of the study area, respectively. It is the main distribution area of city, farmland and water body space, and also the main gathering area of human activities. The shallow mountain area (315.4N 495.6 m above sea level) and the deep mountain area (495.6 m above sea level) account for 19% and 7% of the total area of the study area, respectively. It is the main distribution area of the green space, and is also the important area of the agglomeration of the scenic spots and the protection of the ecological environment.
