|
摘要
随着工业化在大多数国家的普及,城市化进程在全球范围内迅速展开,长期而持续的城市用地扩张导致土地利用方式发生了显著改变,这种改变会对土壤的性质产生深刻影响。国内外对城市土壤的早期研究主要以土壤肥力为中心进行,初步探讨了城市土壤的性质、化学组成等方面。之后,随着全球环境形势的日益严峻,城市土壤碳储存开始受到关注。当前国内外城市土壤有机碳研究主要侧重于绿地土壤表层与次表层的养分特征分析,对有机碳的垂直分布研究较少;缺乏对有机碳时间变化规律的分析;研究对象集中于植被覆盖下的绿地土壤,对无植被覆盖下土壤有机碳的研究十分薄弱;对有机碳组分的分析力度不够,及缺乏对有机碳组分间相互关系的探讨。因而,开展全面而深入的城市土壤有机碳研究,了解城市化过程对土壤有机碳库的影响是十分必要的。本研究以具有2700多年建城史的开封市为研究对象,在调查采样和实验室分析的基础上,从土壤有机碳组成、储量、空间分布和时间变化几个方面开展较系统的城市土壤有机碳分析,以丰富城市土壤有机碳库基础数据信息和城市土壤有机碳研究案例,为城市土壤的科学管理和城市生态系统的可持续发展提供依据。研究中布设了绿地标准土壤剖面样点(25个)、非绿地土壤剖面样点(8个)和绿地表层样点(112个)3种样点类型,共采集绿地土壤标准剖面样品91个,非绿地土壤剖面土壤样品79个,表层绿地土壤样品112个。对土壤样品分别进行了基本理化性质、有机碳、腐殖质碳、轻组有机碳、颗粒有机碳、易氧化有机碳、水溶性有机碳和黑碳的测定。

With the industrialization in most countries, Urbanization carried out in global area. The long–term and continuous land expansion changed the land use and land cover, what had profound influence on soil organic carbon. The early researches of the urban soils focused on the fertility, including the characteristics and chemical components. Afterwards, with the serious situation of global environment, soil organic carbon of urban soils were concerned. The current researches concerned on the topsoil and sub–surface layer of soil, ignoring the vertical distribution of soil organic carbon; concerned on the soil covered by vegetation, ignoring the soil with no vegetation cover; concerned on the total organic carbon, ignoring the components; and the researches on temporal variation of soil organic carbon were not enough. Therefore, to be familiar with the influence of urbanization on soil organic carbon depended on deeper and wider researches. Taking Kaifeng city which had about 2700 yrs city–building history as the research object, the components, storage and temporal–spatial variations of soil organic carbon were studied based on the sampling and experiment. 25 norm soil profiles in greenlands, 8 soil profiles in lands with non–vegetation cover and 112 topsoil samples were set, collecting 91 profile samples in greenlands, 79 profile samples with non–vegetation cover and 112 topsoil samples. The samples were experimented on physical–chemical property, organic carbon, humus, light fraction organic carbon, Particulate organic carbon, Readily oxidizable carbon, water–soluble organic carbon and black carbon. There were nine chapters in the paper, including five sections:
The first section was introduction(the first chapter), including the background, survey, existing problems, trend of urban soil organic carbon; main contents and significance of this paper.
The second section was material and methods(the second chapter), including natural and socioeconomic status , environmental pollution situation; setting and collection of soil samples; experimental methods of items; data processing method; technical route of this paper.
The third section was the components, storage and temporal–spatial variations of urban soils(the third, fourth, fifth and sixth chapter), including storage, difference among functional districts, horizontal and vertical distribution of soil organic carbon, active organic carbon, carbon in humus(carbon in humic acid, fulvic acid and humin) and black carbon.
The fourth section was the temporal variations and variations along transaction line from urban areas to suburbs(the seventh and eighth chapter), including the difference of soil organic carbon in topsoil and profile along the time; the difference of soil organic carbon and active organic carbon in topsoil among different–aging greenlands; variations of soil organic carbon and the components between urban areas and suburbs, and along the transaction line from the center of urban area to suburbs.
The fifth section was conclusion and discussion(the ninth chapter), including the conclusion, deficiency and prospect of this research.
The main results were as follows:
(1)The contents and densities of soil organic carbon in topsoil of urban areas were higher than soils with non–vegetation cover and soils in suburbs.

The storage of soil organic carbon in greenlands was higher than lands with non–vegetation cover; the values of POC and LFOC in urban soils were higher than that in suburbs, the situation of ROC and WSOC were the opposite. The storage of humus in urban soils was lower than that in suburbs, and the percentage of carbon in humus in total organic carbon in urban soils was lower than that in suburbs by 10.76%. The contents of carbon in humic acid and humin were higher in urban soils than that in suburbs, the contents of carbon in fulvic acid in urban soils was lower than that in suburbs by 31%. The value of HA/FA in urban soils was 0.09 higher than that in suburbs. The value of E4/E6 in urban soils was 0.03 lower than that in suburbs. The urban soils had 1.34–fold more BC in topsoil than suburbs.

The order of the contents and densities of topsoil were all industrial district > administrative district> traffic district > residential district > cultural/educational district >recreational district. The SOCD in profile followed the order of cultural/educational district> traffic district >industrial district > residential/administrative district > recreational district. Industrial district and administrative district had the higher storage of POC, ROC and LFOC; cultural/educational district and recreational district had the lower storage of them. However, the storage of WSOC in recreational district was the highest among functional districts, and the storage WSOC in industrial district and administrative district were lower. The storage of carbon in humus and its components were the highest in industrial districts, the lowest in recreational district. The value of HA/FA was the highest in recreational district, the lowest in industrial districts. The order of the value of E4/E6 was cultural/educational district administrative district> cultural/educational district> traffic district> recreational district> residential district.
(3) The storage of soil organic carbon in bare land was higher than that in land with building and road cover. The contents and densities of POC, ROC and LFOC in topsoil all followed the orders of bare lands> lands covered by buildings> land covered by road. The content of WSOC followed the order of bare lands> lands covered by buildings> land covered by road. However, the soils in land covered by road had 1.33–fold and 1.50–fold more density of WSOC than bare lands and lands covered by buildings, respectively.

The shape of horizontal distribution of soil organic carbon was annular, and the contents declined from the east area to northwestern area. The distribution of POC took on a string shape, and the contents declined from southeastern area to northwestern area. The content of ROC declined from the southern area to northern area. The shape of WSOC’s distribution was speckle, with three high value centers in southeastern area and western area in urban area, western area and southeastern area in suburbs, respectively. The value of LFOC declined from eastern area to western area. The value of carbon in humus declined from eastern area to western area, and from the center of urban area to northern area, and to southern area, respectively.

They were mainly distributed within the scope of 0~30cm, with about 40~60% of soil organic carbon, 46.59% of LFOC, 56.41% of POC, 50.31% of ROC. The storage of WSOC in the scope of 0~30cm and 30~60cm were closed, with the percentages of 30.62% and 30.08%, respectively. The components of humus declined with the depth, and the order of regularity was carbon in humin>carbon in humic acid> fulvic acid. There was no obvious variation of HA/FA in vertical distribution. The vertical distribution of E4/E6 followed the regularity of power function(R~2=0.448~0.988,p<0.05). The soil organic carbon and BC in topsoil of lands covered with no vegetation declined with the depth.
(6) The contents and densities in topsoil and densities in profile increased with the time, with the increasing range of 0.99～28.19 g kg~(–1), 0.12～3.39 kg m~(–2) and 0.39～7.59 kg m~(–2), respectively. Period I(before the early of 20th century) had 1.19–fold more content of soil organic carbon and 1.08–fold more SOCD in topsoil than period II(after the early of 20th century), respectively. The contents of LFOC, POC, ROC and carbon in humus of period I were 1.15, 1.35, 1.44 and 1.16 times more than periodⅡ, respectively. There was no obvious rise of WSOC. The value of HA/FA of periodⅠwas lower than periodⅡ.
(7) The storage of soil organic carbon in topsoil and in profile in urban area were higher than that in suburbs along the transaction line. The storage of soil organic carbon declined from the center of urban area to suburbs. There was obvious variation of the contents of carbon in humus along the transaction line. however, the percentage of it in total organic carbon was followed the order suburbs>old urban area> new urban area, and the percentage increased along the transaction line from the center of urban area to suburbs. There was no obvious variation of HA/FA in this line. The value of E4/E6 in urban area was higher than that in suburbs. The storage of LFOC, POC and BC in urban area were higher than that in suburbs, and they all declined from the center of city to suburbs. The storage of WSOC in urban area was lower than that in suburbs, increasing with the distance. The storage of ROC in urban area was similar to that in suburbs, and took on a complicated variation in transaction line. The contents of BC in urban area was higher than that in suburbs, and it declined with the distance.

There was obvious variation of the contents of carbon in humus along the transaction line. however, the percentage of it in total organic carbon was followed the order suburbs>old urban area> new urban area, and the percentage increased along the transaction line from the center of urban area to suburbs. There was no obvious variation of HA/FA in this line. The value of E4/E6 in urban area was higher than that in suburbs. The storage of LFOC, POC and BC in urban area were higher than that in suburbs, and they all declined from the center of city to suburbs. The storage of WSOC in urban area was lower than that in suburbs, increasing with the distance. The storage of ROC in urban area was similar to that in suburbs, and took on a complicated variation in transaction line. The contents of BC in urban area was higher than that in suburbs, and it declined with the distance.
