1979年我们在章丘县埠村公社应用航片(1/24000)进行了土壤普查试点,在较短的时间内,完成了全社的土壤普查,并积累了一些有关航片目视判读土壤和地貌的经验,同时也发现了应用航片进行土壤普查所存在的某些问题。为搞好土壤普查,交流经验,现将初步体会整理于下。 一、在航片上判读土壤的基本方法 埠村公社位于章丘县南部,系泰山山系北麓的低山丘陵区,地形分异明显,土壤类型及利用状况与地形部位的相关密切,而地形、地貌在航片上一般都反映得比较清楚,尤其在立体镜下进行立体观察时,影象显得更加直观,容易较准确地判读出微地貌单元,从而可间接判读出土壤类型。所以我们经过路线踏勘在初步掌握土壤与地形、地貌、母质、利用状况等因子之间的相关性后,即转入室内予判,首先将易于判
In 1979, we carried out a soil census pilot project at Bucun Commune, Zhangqiu County (1/24000). In a relatively short period of time, we completed a soil census of the entire community and accumulated some relevant information on aerodrome visual interpretation of soil and Landform experience, but also found that some of the problems of using aerial photos for soil census. To do a good job of soil census, exchange of experience, now will be the initial experience finishing. First, the interpretation of the basic methods of aerial photos Bucun commune is located in southern Zhangqiu County, Department of the northern foot of the Taishan Mountain hilly region, obvious topographic differences, soil types and utilization of the terrain and the site closely related to the topography, Geomorphology is generally reflected in the aerial photos more clearly, especially in the stereoscopic microscope, the image is more intuitive, easy to interpret the micro-geomorphological units more accurately, which can indirectly interpret the soil type. Therefore, after our initial exploration of the correlation between the soil and topography, topography, parent material, utilization and other factors, we transferred to the indoor judgment. First, we will make it easy to judge
