【摘要】 土地利用情况反映了国家地质资源的使用状况,能够反映资源和环境现状。现阶段对于土地利用时空变化的研究十分丰富,本文以焦作市为例,对该地区土地利用现状进行分析。首先本文选择2010和2018年焦作市Landsant8遥感影像,在ENVI软件中对该地区土地利用情况进行监督分类,之后在ArcGIS中对分类结果进行提取分析。在进行空间分析之后发现8年间土地利用情况有很大改变,2010-2018年间焦作市水体面积增加了3%,建设用地增加了6%,耕地面积减少15%,林地增加6%。通过数据分析发现,经济的快速发展和国家环保政策的推行,对土地利用状况具有较大影响。更多还原

【Abstract】 Land use reflects the use of national geological resources and reflects the current state of resources and the environment.At present,the research on the spatial and temporal changes of land use is very rich.This paper takes Jiaozuo City as an example to analyze the current situation of land use in this area.Firstly,this paper selects the Landsant8 remote sensing image of Jiaozuo City in2010 and 2018,and supervises and classifies the land use situation in the area in ENVI software,then extracts and analyzes the classification results in ArcGIS.After the spatial analysis,it was found that the land use situation changed greatly during the 8 years.In 2010-2018,the water area of Jiaozuo City increased by 3%,the construction land increased by 6%,the cultivated land area decreased by 15%,and the forest land increased by 6%.Through data analysis,it is found that the rapid development of the economy and the implementation of national environmental protection policies have a greater impact on land use.更多还原
