摘要
东北黑土区是目前关注较多的话题,但其界定非常混乱。因此,有必要理清东北黑土区的界定及其分类体系。通过对比各种黑土和黑土区数据,对文献中存在的黑土及典型黑土、东北黑土区及东北典型黑土区等概念进行了归纳,并将东北黑土区研究分为黑土演化历程、广义东北黑土区演化历程和狭义东北黑土区演化历程3方面。其中,黑土演化历程包括黑土演化与确立(1978年前)和典型黑土界定(1979年至今)2个阶段,形成了第一次全国土壤普查黑土数据、第二次全国土壤普査和全国数字化土壤图的典型黑土数据等3套数据。广义东北黑土区演化历程包括暂时数据界定阶段(2002年~2003年)和正式数据界定阶段(2004年~2008年),分别形成广义东北黑土区暂时数据和正式数据。东北典型黑土区演化历程包括2个阶段:东北典型黑土分布区界定阶段(1978年~2006年)和东北典型黑土区(狭义东北黑土区)界定阶段(1992年至今)。前者存在4套代表性数据:松嫩典型黑土(专指黑土)分布区数据、松嫩典型黑土(黑土和黑钙土)分布区数据、黑吉2省农业区划的东北典型黑土(黑土、黑钙土和草甸土)分布区数据和WRB(1994)估算的东北典型黑土(厚度225 cm的黑土和草甸土)分布区数据;典型黑土区界定阶段,以松辽委1992数据、黑龙江水保所数据、松辽委2004数据和北师大数据4套数据为代表,它们依次界定了松嫩东部典型黑土区,松嫩典型黑土区,松嫩和呼伦贝尔典型黑土区,松嫩、呼伦贝尔和三江典型黑土区。研究有助于学者根据需要选用恰当的东北黑土区范围和面积数据,对于深化东北黑土区研究具有一定的促进作用。
The concept of"Black Soil regions of Northeast China"is currently a more concerned topic,but the definitions are seriously confused.It's necessary to clarify the boundaries and classification systems of Black Soil regions.Based on the data of Black Soils and Black Soil regions,the concepts of Black Soils,typical Black Soils,Black Soil regions and typical Black Soil regions of Northeast China in the current literature were summarized.The current research of the Black Soil regions in Northeast China was divided into 3 evolution histories of Black Soils.The evolution process of Black Soils included the evolution and establishment stages of Black Soils(before 1978)and the definition stage of typical Black Soils(1979一present).And the Black Soil data from the first national soil survey,the second national soil survey and the national digital soil map were obtained.The evolution process of generalized Black Soil area of Northeast China covered the definition stage of temporary data(2002-2003)and the definition stage of formal data(2004一2008).The development process of typical Black Soil regions of Northeast China included 2 definition stages of the distribution of typical Black Soil regions(1978一2006)and narrow Black Soil regions(1992 to present).During the earlier stages,the distribution data of typical Black Soil regions were gained,including the Black Soil type,the Black Soil and Chernozem types in the Songnen Plain,the Black Soil,Chernozem and Meadow soil types in the agricultural division regions of Heilongjiang Province and Jilin Province,and the Black Soil and Meadow Soil types with thickness h 25 cm in Northeast China estimated by WRB(1994).During the definition stage of typical Black Soil regions of Northeast China,the representative data were formed from Songliao Commission in 1992,from Heilongjiang Water Conservation Bureau,from Songliao Commission in 2004,and from Beijing Normal University.This review would help the researchers to select the appropriate area data of Black Soil in further research.
