【摘要】 科学的土地研究方法,首先要建立一个能够体现土地分布与演变规律的概括性框架,即土地类型分类系统。有了这样一个框架,就能够对土地的共性加以定义和描述,也才能将地域上分隔的土地类型联系起来。土地作为一种可更新资源受社会和自然条件的影响,处于不停的变化之中。认真研究土地的动态变化规律,才能真正查清土地的性状,进而提出合理利用方案。多时相、多平台、多波段系列遥感资料,为土地资源调查提供了丰富的信息。充分发挥遥感技术在资源调查中应用的潜力,是今后土地调查方法研究的一个重要内容。更多还原

【Abstract】 As a scientific way of land resources research, it should bo the toppriority to build up a general framework,i.e.,land classification system,which can imbody distribution and evaluation of land resources. In thiscase, common land features can be definited and described, and land typesspatially departed can be linked.Being a kind of renewable resources, landalways is in variation due to influence of social and natural conditions.Onlyland dynamic law was studied deeply, all land features can be ascertain-ed and reasonable land use plan can be worked out. A series of romotelysensed data of multi-times, spectra and platforms supply abundant infor-mation to land resources investigation. It is one of the most importanttask in the future land research to give a full play of remote sensing po-tentialities.更多还原
