| 摘 要： | 农田土壤质量评价是耕地地力升降实行奖惩使用的前提。由于当前耕地土壤质量评价是以地块、地片为基础进行的。为适应这一需要,我们在第二次全国土壤普查的基础上,以太谷县为试点,将土壤普查土壤分类中之土种以下通过因素重迭法续分为土种—变种—土片三级基层分类;同时以1/万地形图作底图,用航片与地形图上对应明显地物点分别建立相应菱形锁,用相似透视网格法按成图比例尺转绘成(1/5000、1/2500或1/万)地形地块(片)及土壤质量等级图、作为农田地力升降奖惩的图幅依据。

| Abstract: | Farm soil quality appraise is the prerequisite to realize the system of rewards and punisher- ents for using farm.For the farm soft quality is evaluated on tracts at present,the three grades of basic soil classification with factor overlap methed—soil species,soil variety and tract—were u- tilized to classify the soil types under the soil species in Taigu county.The linear lock was formed between the surface features on aerial photographs and the homologues on 1/10000 topographic maps and the 1/5000 or 1/2500 or 1/10000 topographic tract maps and soil quality grade maps were drawn with similar perspective net—check method.The topographic tract maps and soil quality grade maps can be used as the basis of reward or punishment for using field. |
