金普新区2013—2018耕地利用变化分析

Analysis of Cultivated Land Use Change in Jinpu New Area from 2013 to 2018

主要以大连金普新区2013、2015、2017、2018年4个年份的地理国情数据为基础,通过对其数据进行分类、融合处理,得到成果数据。然后应用相关GIS手段获取各个年限下研究区域的耕地面积以及各个年份间的耕地具体转化情况。通过对其进行研究,能够直观地对新区成立以来耕地的利用以及变化情况有所认识。研究结果表明:新区成立初期,耕地的主要流转方向是林草植被,后期以转换向人居用地为主。随着新区发展,耕地变化渐渐趋于稳定。

Based on the geographical and national conditions data of Dalian Jinpu New Area in the years of 2013,2015,2017 and 2018,this paper classifies and fuses the data to get the result data.Then,the cultivated land area and the specific conversion of cultivated land in different years were obtained by using relevant GIS.Through the study,we can intuitively understand the utilization and change of cultivated land since the establishment of the new area.The results show that in the early stage of the establishment of the new area,the main transfer direction of cultivated land is forest and grassland vegetation,and in the later stage,the conversion to residential land is dominant.With the development of the new area,the change of cultivated land tends to be stable.
