摘要
通过分析中国耕作层土壤剥离利用研究现状,提出耕作层土壤剥离利用的关键问题和主要方向。运用文献调研法,剖析中国耕作层土壤剥离利用在类型、土壤调查评价、剥离、储存和回覆等技术环节,以及组织管理模式等方面的探索与实践。现阶段中国耕作层土壤剥离利用研究以实证分析为主,研究对象主要为试点市县和部分单独选址项目;耕作层土壤剥离利用工作暂无统一遵循的规范程序和技术体系,各技术环节均缺乏标准提炼;理论研究比较薄弱,暂未形成规律性总结。今后中国耕作层土壤剥离利用的研究重点是:健全完善规章制度,加强监督管理;规范耕作层土壤剥离利用程序,制订实施的技术标准;建立和完善耕作层土壤剥离利用相关的激励和约束机制;吸收国外耕作层土壤剥离利用的有益经验,探索在中国更具可行性和可操作性的路径和方法。以期为有效保护耕地资源,稳定粮食生产及保护生态环境提供科学指导。
[Background]The plow layer soil is the material base for grain growth,and is a precious natural resource,which is difficult to regenerate.However,with rapid development of industrialization and urbanization processes,cultivated land is inevitably occupied by construction.Therefore,the retention of plow layer soil occupied by the construction is an urgent task,which is meaningful for the protection for plow land and ensuring food security.The purpose of this paper is to figure out the key scientific problems and main directions of plow layer soil stripping and using by analyzing the research status in China.[Methods]The method of literature retrieval is applied to investigate the exploration and practice in the type,soil investigation and evaluation,stripping,storage,backfilling and other technical aspects,organization and management model of plow layer soil stripping and using in China.Then,the comprehensive analysis is used to reveal the research status of the above listed content on the plow layer soil stripping and using in China.Finally,the scientific issues for further research are proposed.[Results]The plow layer soil stripping and using involves many aspects,including soil investigation and evaluation,soil stripping,soil storage,soil transportation and backfilling.The research on plow layer soil stripping and using in China is mainly on empirical analysis,and the main research objects are pilot cities and counties,and projects of individual site selection.Due to the differences in application objects and main objectives of surface soil stripping,there is no standard procedure and formal system in plow layer soil stripping and using.Technical aspects are lack of standard extraction.The uniform standard and fixed method is lack in the processes of soil investigation and evaluation.And the modes of organization and management of surface soil stripping show differences in response to different application objects.In general,theoretical research on the soil stripping is relatively weak and only focuses on the description and discussion.In addition,due to differences of natural condition,resources and plow land,there is no regularity summary of soil stripping yet,and the universal law of plow layer soil stripping and using is not attained.[Conclusions]The paper concludes that the research focusing on plow layer soil stripping and using are to revise rules and regulations,strengthen supervision and management,standardize procedure of plow layer soil stripping and using,develop implementation standard,establish and improve relevant incentive and restraint mechanisms for plow layer soil stripping and using,absorb the beneficial experiences of foreign countries and explore more feasibility and workable paths and methods in China,which not only effectively protect cultivated land resources,but also have important significance to stabilize food production and protect ecological environment.
