摘要/Abstract

摘要： 利用地理信息系统技术和地学综合分析方法,对黄土高原(陕西部分)的水分生态环境区域空间格局进行了研究,并获取了1:50万的陕西黄土高原水分生态环境区域空间格局图.结果表明,黄土高原区域水分生态空间格局受气候(降水)、土壤(质地)、地质(黄土堆积厚度)、地形(区域地貌)、植被等多因素的综合作用,并可由上述系列因子进行分别度量;用不同植被的适生性作为区域水分生态状况的综合度量指标;陕西黄土高原的区域水分生态环境涉及乔木适生区、灌丛适生区和草被适生区3种类型,且在空间上具有镶嵌性,其主体则为乔木适生区,反映了该区具有生态良性恢复的巨大潜力.

关键词: 水分环境, 空间格局, GIS, 黄土高原

Abstract: Based on the integration of GIS and geo-synthesis analysis,the water circumstances for plant growth in the Shaanxi Loess Plateau area were studied and a map reflecting regional water circumstances at the scale of 1: 500 000 was made.The results showed that the water circumstances for plant growth in the Loess Plateau area were affected by the integration of precipitation soil texture,loess deposition,geomorphology and coverage,and could be measured by sub-indicators from the mentioned aspects.The index from the view point of plant development was used for the water circumstance assessment.The water circumstances of the Loess Plateau including forest zone,shrub zone and grassland zone appeared a complex spatial mosaic structure,and the main of the plateau was suitable for forestry which meant the plateau had an expected potential for eco-restoration.

Key words: Water circumstances, Spatial patterns, GIS, Loess Plateau
