湾塌地是陕北黄土丘陵沟壑区一种独特的侵蚀地貌类型.塌地由于水分条件好、地势平缓,且往往被细长梁状分水岭所环绕,形成良好的小气候单元,为农作物生长提供了良好的生态环境条件,因而是当地农业生产上宝贵的土地资源.但长期以来,由于技术手段的限制,对安塞县湾塌地类型及分布规律等资源现状,底数不清.1986年9月至1987年6月,我们应用彩红外航空遥感信息源进行了湾塌地的分类解译、制图及量化等摸清资源现状等工作,为湾塌地的治理和开发利用规划提供了科学依据.
Bay collapse is a unique type of erosion landform in the loess hilly and gully regions of northern Shaanxi, where, due to its good water conditions, gentle terrain and often surrounded by slender beam-shaped watersheds, favorable microclimate units are provided for crop growth Good ecological environment conditions, and therefore is a valuable agricultural land resources, but for a long time, due to technical means restrictions on the Ansai County Bay landfall types and distribution of resources such as the status quo, the bottom is not clear. By June 1987, we applied color infrared remote sensing information sources to classify the interpretations, mapping and quantification of the collapsed land in the Bay so as to find out the status quo of the resources so as to provide a scientific basis for the management and development and utilization planning of the collapsed land in the Bay.
