摘要

县级土地资源清查

是与国民经济建设密切相关

且是迫切需要解决的问题。遥感资料为此提供了丰富的信息。据我们十几年的实践

遥感技术与常规地面调查相结合的方法

既能保证精度

又缩短了调查周期

是一种经济有效的方法。在今后相当一段时间内仍将广泛适用。主要作法是:1、建立资源卫星影象和航空象片解译标志;2、在卫片上判读Ⅰ、Ⅱ级土地类型;3、选择样区进行实地调查;4、航片细部判读与转绘;5、以土地类型为基本单元进行土地潜力评价;6、量算面积和编写报告。

Abstract

County-level land resources inventory has been regarded as one of the nation's priorities. According to our practices of more than ten years

remotely sensed data can provide abundant information for this work

and we consider that Landsat image and airphoto interpretation in cooperation with the traditional method is an effective and economic way

and would be the main approach for land resources inventory in the near future. Our main procedures are

(i) Landsat image interpretation and working out the highlevel land classes;(ii) Using airphoto and field check in the sampling areas to complete the land classification system，and establishing the interpretation criteria as well; (iii)Airphoto interpretation and transfering of land type and land current use;(iv)Land capability evaluation on the basis of land type;and (v) Measuring of area and compiling of reports involved. The final results include 3 maps(Land Type，Land Current Use and Land Capability)，land resources inventories and reports.During the last several years the results mentioned above have effectively and. successfully been used by the local authorities.
