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。

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 ascertained and reasonable land use plan can be worked out. A series of romotelysensed data of multitimes

spectra and platforms supply abundant information to land resources investigation. It is one of the most importanttask in the future land research to give a full play of remote sensing potentialities.
