耕作层土壤剥离再利用模式研究——以安徽省为例

Study on the Patterns of Arable Layer Topsoil Stripping and Reuse—A Case Study of Anhui Province

耕作层土壤剥离再利用是切实保护资源、保护耕地的系统性工程,在各地已有实践。该研究在对已有土壤剥离再利用模式进行综述和分类的基础上,归纳了各模式的运行方法、优缺点和适用条件。并以安徽省为例,构建了判定规则,对全省16地市的耕作层土壤剥离利用模式选择提出了相关建议,旨在为全省建立土壤剥离利用制度找出方法及突破口。

Topsoil stripping and reuse, existing in practice in the country, is a systematic project with effectively conserving resources and pro- tecting farmland. On the basis of reviewing and classifying the patterns of arable layer topsoil stripping and reuse, the operation ways, advantages and disadvantages, and applicable conditions were summarized. Taking Anhui Province as an example, the determination model was built and was used to select the patterns of 16 cities. The results could find out some method breakthrough for establishing topsoil stripping and reuse sys- tem in Anhui Province.
