摘要
耕地坡度等级分析在土地适宜性与生产能力调查和土地质量评价的占有重要地位,同时实现了应用GIS技术来处理土地利用现状数据的需求。本文利用ArcGIS软件,根据云南省托姑村和黑土村耕地所处地势的坡面坡度,按对耕地利用的影响限制程度而划分级别,从坡度分级、数据拓扑等方面分析ArcGIS在耕地坡度分级中的应用。本文实例区耕地中以旱地为主,耕地的坡度分为五个级别,每个坡度级别中耕地都占有一定的比重。基于本文中的操作,也可考虑耕地整理在土地综合生产能力提高、生态环境改善、景观优化方面的潜力,这也是一项重要的研究。
The grade analysis of cultivated land slopes occupies an important position in land suitability and production capacity surveys and land quality assessments,and at the same time it realizes the application of GIS technology to deal with land use status data needs.In this paper,ArcGIS software is used to classify the slope gradient of cultivated land according to the degree of influence on the use of cultivated land in TuoGu and HeiTu countries of Yunnan.The application of ArcGIS in slope grade of cultivated land is analyzed from slope classification and data topology.The cultivated land in this example area is dominated by dry land,and the slope of cultivated land is divided into five levels.The cultivated land in each slope class occupies a certain proportion.Based on the operations in this paper,the potential of arable land consolidation in the improvement of comprehensive land production capacity,improvement of ecological environment,and landscape optimization can also be considered,which is also an important research.
