关于耕作层土壤剥离用于土壤培肥的必要条件探讨

Prerequisites for Preserving the Fertility and the Soil Layer Before Farmland Converted for Construction Use

研究目的：探讨不同区域耕作层土壤剥离用于新增耕地、劣质耕地土壤培肥的必要条件。研究方法：现象溯因法和综合分析法。研究结果：不同土壤类型的耕地其土壤肥力水平和在剖面中的分布特征不一样。研究结论：开展耕作层土壤剥离再利用应该因地制宜，使得取土区的供土状况与填土区的需土条件相互匹配。

The purpose of this paper is to discuss the prerequisites for preserving the fertility and the soil layer for future use before the land is converted for construction use. Methods of phenomenon reasoning and comprehensive analysis were used. The results indicated that the fertility of soil and its distribution features were different regarding different types of soil. The paper concluded that to reuse the soil layer of the land converted for construction should take the local condition into account, matching the original features of the preserved soil with the condition of the new land.
