本文讨论的范围大致是黑龙江省肇州县的头台、泰来县的大兴和内蒙古自治区突泉县的突泉镇之间的三角地区.在土壤地理区域上,北部和东北部邻接黑钙土,西部毗连山地栗钙土.一些研究者,曾把该区的地带性土壤称之为碳酸盐化灰钙土、草甸黑土、黑钙土等;中国自然区划和中国土壤区划亦把本区划归温带半湿润地区草原黑土地带;近年,中国科学院内蒙宁夏综合考察队则将其西部划为暗栗钙土,但新出版的中国土壤一书则仍把本区大部作为黑钙土.根据我们1977—1978年对该区植被和土壤调查,并结合有关资料的分析,我们认为把本区划归温带半干旱地区草原栗钙土地带更为妥当,现就地带性土壤作一概述.
The scope of this paper is roughly the triangular area between Toutai in Zhaozhou County, Heilongjiang Province, Daxing County in Tailai County and Tuquan Town in Tuquan County, Inner Mongolia Autonomous Region.On the soil and geography area, the northern and northeastern regions are adjacent to Chernozem , Adjoining the mountain chestnut soil in the west.A few researchers once referred to the zonal soil in this area as carbonate calcareous soil, meadow black soil, chernozem soil and so on; Chinese natural division and Chinese soil division Divided into the temperate semi-humid grassland black soil zone; in recent years, the Chinese Academy of Sciences Inner Mongolia Ningxia comprehensive expedition will be divided into the western part of the dark chestnut soil, but the newly published soil in China is still a book most of the area as Chernozem Based on our survey of vegetation and soil in the area from 1977 to 1978 and the analysis of relevant data, we think it is more appropriate to divide the area into the chestnut-lime soil zone in the temperate semi-arid area, and we will give an overview of the zonal soil .
