摘要

<正> 欲了解一个地区的盐渍、风沙、积涝土壤的变化

必须研究该地区这些土壤在不同时期的分布状况。要查清这些土壤的分布现状

只要利用最新的航空像片进行土壤遥感制图即可做到。但要了解它们自某个历史时期以来的变化情况

由于时过境迁

则不很容易。而航空像片不仅详细、真实地记录了不同时期的土壤分布状况

而且还记录了它们在不同时期所处的环境条件

如排灌、植被、利用方式等状况。借助不同时期的航空像片来比较、分析各种土壤的分布状况及有关环境条件的变化

可以研究某些土壤的变化和引起其变化的原因。在天然文岩渠流域盐渍、风沙、积涝土壤历史变化的研究中

我们以1957和1983年的航空像片为主要资料

完成了所述的研究任务。

Abstract

The key of studying the historic change of salinized

aeolian sandy and waterlogged soils by using the aerophotos tanken at different times is as follows: （1） selecting the aerophotos tanken at the best time

（2） adopting a uniforme soil classification system and mapping units and （3） a transference method with high accuracy. Aerophotos tanken at different times can be used for studying not only the change of area of the salinized soil

aeolian sandy and waterlogged soil

but also the factors which cause these changes

all these are a base for determining some proper methods for ameliorating the soils.
