摘要: 在首都圈生态地理分区的基础上,运用GIS技术,对首都圈4个生态地理区的土地利用现状图和土地资源图进行叠加处理和对比分析,得出研究区域易于起沙的疏林地、低盖度草地、河滩地、沙地、盐碱地、沼泽地和裸土地等7种用地类型的转化方向、转化面积和空间布局,为首都圈的防沙治沙和生态环境建设提供依据。

关键词: 合理转型, 首都圈, 土地利用, 土地适宜性

Abstract: The conflict of the need and supply of land and water in many regions is more and more sharp And the irrational use of land and water might cause environmental deterioration and sandy storms In this paper, the data was from digital land use map of 2000 of Resources and Environment Data Center of IGSNRR, CAS and the land resource map of PRC, which was digitized by myself Based on these data and the ecogeographic regionalization, GIS method was used to analyze the land use status and land suitability of 4 ecogeographic regions The conversion land use types, area and spatial distribution of the 7 low degree of vegetation cover land use types, such as sparse forest land and low degree of grass cover land in deferent regions, were achieved Based on those findings.

Key words: land suitability, land use, rational conversion, region around Beijing(RAB)
