基于GIS技术的湖南省土地分区

摘要

According to 1:1million soil, topographic and geological map, this paper studies the zoning of Hunan province based on soil type, topography and geology category by using MAPGIS space overlay method. The results show that: the province is divid-ed into four areas, including basic agricultural development zone, agricultural and industrial development zone, protection and moderate development zone, ecological protection and tourism devel opment zone. Combined with regional development strategies and policies, the writer concludes strategic layout of the districts and proposes reasonable direction for regional land use, which are favor of the province's sustainable land use.%借助1：100万湖南省土壤图、地形图和地质图，以土壤类型、地形高度和地质类别为依据，运用MAPGIS空间叠置法，对湖南省土地进行了分区研究。结果表明：全省共划分为四个区，包括基本农业发展区、农业和工业发展区、保护和适度开发区、生态保护和旅游发展区。结合区域发展战略、政策，对各区进行了战略布局，提出了区域土地利用的合理方向，研究为全省的土地可持续利用提供了科学依据。
