摘要:

【目的】国务院第三次全国土壤普查领导小组办公室(简称国务院三普办)2023年下发了《第三次全国土壤普查暂行分类系统(试行)》(简称《三普暂行分类》),但没有建立检索系统。为在土壤调查过程中避免发生同土异名、同名异土问题,特构建土类检索系统。【方法】依据农业重要性优先、确名先易后难、涵义先窄后宽、类型相似集中、体现土壤空间演变和发育规律等检索秩序原则,通过引用已有的诊断层/诊断特性、修改已有的诊断层/诊断特性、简洁化描述性语句、归纳特征土层等方法,从《三普暂行分类》土类划分依据中提炼各个土类的检索指标,构建土类检索系统。【结果】建立了包含《三普暂行分类》中62个土类的检索系统,检索秩序依次为:1工程土、2水稻土、3菜园土、4灌淤土、5灌漠土、6碱土、7寒原盐土、8漠境盐土、9酸性硫酸盐土、10滨海盐土、11草甸盐土、12火山灰土、13寒冻土、14紫色土、15磷质石灰土、16石质土、17粗骨土、18龟裂土、19新积土、20风沙土、21黄绵土、22红黏土、23石灰(岩)土、24白浆土、25灰化土、26棕色针叶林土、27暗棕壤、28棕壤、29黄棕壤、30黄褐土、31灰色森林土、32黑土、33灰褐土、34褐土、35燥红土、36黑钙土、37栗钙土、38栗褐土、39黑垆土、40棕钙土、41灰钙土、42灰漠土、43灰棕漠土、44棕漠土、45山地草甸土、46林灌草甸土、47砂姜黑土、48草甸土、49潮土、50沼泽土、51泥炭土、52砖红壤、53赤红壤、54红壤、55黄壤、56黑毡土、57草毡土、58寒钙土、59冷钙土、60冷棕钙土、61寒漠土、62冷漠土、63类型待定土。【结论】总体上,《三普暂行分类》的土类是可以通过剖面形态、土壤理化性质建立起检索指标的,但是高山土纲的多数土类没有完全遵循整个分类系统的分类原则,彼此之间难以从剖面形态和土壤理化性质上进行区分,需要利用分布区域、海拔等非土壤本身属性才能区分;《三普暂行分类》的土类还需要进一步完善,建议对部分土类要进行适当归并,同时增加一个“性土”土类。

Abstract:

【Objective】The State Council’s Office of the Leading Group for the 3rd National Soil Census released China’s Provisional Soil Classification System for the 3rd National Soil Census (Trial), abbreviated as 3PSC-T, in 2023, without retrieval system, which is unable to address long-standing questions such as “one soil having multiple names” and “different soils sharing the same name”. Therefore, the retrieval system for great soil groups need be built. 【Method】The retrieval indicators for each great soil group were extracted from the soil classification basis in 3PSC-T by using multiple methods, such as referring to existing diagnostic horizons and characteristics, refining existing diagnostic horizons and characteristics, simplifying descriptive statements, and inducting characteristic soil layers. Four principles for retrieval order were set up, which included prioritizing the importance of agriculture, prioritizing ease over difficulty in identification, narrowing down meaning, clustering similar types, and reflecting the spatial evolution and development patterns of soil. 【Result】Consequently, the retrieval system for 62 great soil groups in 3PSC-T was established, and the retrieval order was: 1 Artificial soils, 2 Paddy soils, 3 Vegetable cultivated soils, 4 Irrigation silting soils, 5 Irrigated desert soils, 6 Solonetzs, 7 Frigid plateau solonchaks, 8 Desert solonchaks, 9 Acid sulphate soils, 10 Coastal solonchaks, 11 Meadow solonchaks, 12 Volcanic soils, 13 Frigid frozen soils, 14 Purplish soils, 15 Phospho-calcic soils, 16 Lithosols, 17 Skeletal soils, 18 Takyr, 19 Neo-alluvial soils, 20 Aeolian soils, 21 Loessial soils, 22 Red primitive soils, 23 Limestone soils, 24 Bleached baijiang soils, 25 Podzolic soils, 26 Brown coniferous forest soils, 27 Dark-brown earths, 28 Brown earths, 29 Yellow-brown earths, 30 Yellow-cinnamon soils, 31 Gray forest soils, 32 Black soils, 33 Gray-cinnamon soils, 34 Cinnamon soils, 35 Torrid red soils, 36 Chernozems, 37 Castanozems, 38 Castano-cinnamon soils, 39 Black loessial soils, 40 Brown calcic soils, 41 Sierozems, 42 Gray desert soils, 43 Gray-brown desert soils, 44 Brown desert soils, 45 Mountain meadow soils, 46 Shrubby meadow soils, 47 Shajiang black soils, 48 Meadow soils, 49 Fluvo-aquic soils, 50 Bog soils, 51 Peat soils, 52 Latosols, 53 Latosolic red earths, 54 Red earths, 55 Yellow earths, 56 Dark felty soils, 57 Felty soils, 58 Frigid calcic soils, 59 Cold calcic soils, 60 Cold brown calcic soils, 61 Frigid desert soils, 62 Cold desert soils, and 63 Cambosol. 【Conclusion】It was found that some soil groups in 3PSC-T had overlapping or inclusive associations with one another. This necessitates the creation of a retrieval system to effectively address the issue of “one soil having multiple names” and “different soils sharing the same name”. In general, the majority of the soil groups in 3PSC-T had the ability to provide retrieval indicators through the examination of profile morphology as well as physical and chemical properties of the soil. Nevertheless, the soil groups within the alpine soil order deviated from the classification principles of the overall classification system. This deviation posed challenges in differentiating them based on profile morphology and soil physicochemical properties. Instead, distinguishing these soil groups required consideration of non-soil properties, such as distribution area and altitude. Further efforts were required to enhance the categorization of soil types in 3PSC-T. It is suggested to incorporate specific groups and to establish a new group called Cambosol.
