基于ArcGIS对鹤庆县松桂镇农用土地变化的研究分析

Research and Analysis of Agricultural Land Change in Songgui Town of Heqing County Based on ArcGIS

土地资源是不可替代且有限的资源,特别是农用土地,在保障农业生产的同时也要承担城市化进程中建设用地的供给。研究农用土地的地类转换特征及变化规律,分析地类变化的驱动因子,可以探索土地利用的发展方向,进而能为土地规划布局提供参考和指导。利用ArcGIS对云南西北部的鹤庆县松桂镇2006年、2011年、2016年、2021年的土地利用矢量数据进行分析,研究其土地利用幅度、程度以及地类相互转换的变化特征、过程和规律,对农用土地变化的驱动因子进行分析。根据结果提出问题和建议。

Land resources are ireplaceable and limited resources,especially agricultural land,which should bear the supply of construction land in the process of urbanization while ensuring agricultural production.Studying the characteristics and changes of land conversion of agricultural land and analyzing the driving factors of land change can explore the development direction of land use,and then provide reference and guidance for land planning and layout.Using ArcGIS to analyze the land use vector data of Songgui Town,Heqing County,Northwest Yunnan in 2006,2011,2016 and 2021,the characteristics,processes and laws of land use range,degree and land type conversion were studied,and the driving factors of agricultural land change were analyzed,and we can put forward questions and suggestions based on the results.
