本文从自然地理特征入手,在分析土地类型形成、分异与演替基础上,结合编制1:5万,1:10万和1:20万土地类型系列图的实践,探讨了上地分级与分类的理论,将该区域分为11个土地型(一黄级),82个土地类(二级),它们分别属于土石山地、土台地和倾斜平地、黄土沟间地和沟谷地等土地演替系列,具有不同的演替过程、演替方向和演替速率。上地类型在空间有规律地组合成土地类型结构,并在此基础上,计算了土地生产潜力和用模糊评判方法进行土地评价。 文章在上述讨论基础上,将晋西与晋西北土地类型组合成12个自然小区,5个自然亚区,2个自然区。然后,从资源、环境和区位三个方面进行分析,提出自然亚区的国土整治方向和治理措施。 论文8万余字,附图21幅,表格31张。
Based on the analysis of the formation, differentiation and succession of land types, combining with the practice of compiling 1: 50000, 1: 100000 and 1: 200000 land type series maps, According to the classification theory, the area is divided into 11 land types (one yellow level) and 82 land types (second level), which belong to the land play of rocky mountainous land, terraced land and inclined land, land between loess and ditch and valleys For the series, there are different succession processes, succession directions and succession rates. On the type of land in the space regularly combined into a land type structure, and on this basis, calculated the potential of land production and fuzzy evaluation method for land evaluation. Based on the above discussion, the article combines the types of land in western Shanxi and western Shanxi into 12 natural areas, 5 natural sub-areas and 2 natural areas. Then, from three aspects of resources, environment and location, this paper puts forward the direction of national land remediation and governance measures in the natural subregion.
