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。
Scientific land research methods, we must first establish a general framework that can reflect the law of land distribution and evolution, namely land type classification system. With such a framework, the commonalities of land can be defined and described, and the types of land separated by geography can be linked. As a renewable resource, the land is under constant social and natural conditions. Seriously study the law of dynamic changes in the land, we can really find out the traits of land, and then put forward the rational use of programs. Multi-temporal, multi-platform, multi-band series of remote sensing data provide a wealth of information for the investigation of land resources. The potential of remote sensing technology to be used in resource investigation is fully exerted, which is an important part of the research on land survey methods in the future.
