Abstract Studying the spatial distribution pattern of soil organic carbon and its influencing factors is essential for understanding cycle in terrestrial ecosystems. Soil samples from four active layers typical vegetation types (Populus, subalpine shrubs, Picea crassifolia Kom, alpine meadow) upper reaches Shiyang River basin Qilian Mountains were collected to determine content physicochemical properties. The results show following: (1) There are significant differences vertical watershed,...
Sophora davidii (Franch.) Kom. ex Pavol is an important medicinal plant and a feeding scrub with ecological value. The effects of different gamma irradiation doses (20-140 Kr) on seed germination seedling morphology were investigated in S. davidii, intersimple sequence repeat (ISSR) markers used to identify the DNA polymorphism among mutants. Significant variations observed for germination, stem diameter, number branches per plant. improved agronomic traits, such as diameter plant, recorded...
Studies on the impacts of grazing carbon, nitrogen, and phosphorus stoichiometry storage are crucial for better understanding nutrient cycles grasslands ecosystems. Using a controlled experimental platform in meadow steppe ecosystem, effects different stocking rates (0.00, 0.23, 0.34, 0.46, 0.69, 0.92 AU ha−1) contents plant functional groups were explored. The major results were: (1) carbon content Gramineae Barnhart was significantly reduced by intensity (p < 0.05), organic Cyperaceae...
基于长序列遥感影像数据、水位日观测数据以及高精度湖盆地形数据,通过提取洞庭湖1987—2016年湿地植被信息,并构建表征水位波动的多周期水情变量,采用逐步回归分析法识别影响洞庭湖湿地植被分布格局的关键水情变量并建立其与植被面积的响应关系.结果表明:1)1987—2016年,洞庭湖湿地典型植被面积在全湖尺度上呈增加趋势,尤其是林地面积,占比由1.77%上升为7.24%.湿地植被格局演变上,东洞庭湖呈现芦苇群落挤占苔草群落空间,并推动湿地植被整体向湖心扩张的趋势.2)影响东洞庭湖苔草和芦苇分布最关键的水情变量是丰水期水位.苔草对丰水期水情存在非线性阈值响应,丰水期平均水位维持在29 m左右,最适宜苔草生长;对于芦苇,丰水期偏枯的水情条件对其生长发育起到促进作用.涨水期和退水期水文过程是影响东洞庭湖湿地植被分布的次为重要的水情因子.涨水期、退水期水位偏低的水情条件对芦苇分布面积的扩张起促进作用.;In this paper, based on the remote sensing image data, hydrological data from 1987 to 2016, and...
The use of ecological stoichiometry is quite effective for exploring the nutrient dynamics and relationships between plants soils. However, way that plant soil changes with remediation in mining ecosystems remains unclear. Biochar vermicompost are generally applied to remediate contaminated soil. In this study, a pot experiment was conducted mine planted alfalfa. (B) (V) were added separately three different proportions, equivalent application rates (w/w) 0% (control, CT), 2.5% (low rate,...
Biodiversity experiments have shown that soil organic carbon (SOC) is not only a function of plant diversity, but also closely related to the nitrogen(N)-fixing plants. However, effect N-fixing trees on SOC chemical stability still little known, especially with compounding effects tree species diversity. An experimental field manipulation was established in subtropical plantations southern China explore impacts richness (i.e., one, two, four and six species) with/without stability, as...
Litter decomposition plays a pivotal role in carbon (C) and nutrient cycling terrestrial ecosystems. However, little is known about the litter processes dynamics urban green space. In this study, of leaf fine roots from Cinnamomum officinarum Nee ex Wall. Elaeocarpus decipiens Hemsl. were studied an forest subtropical China. The results showed that mass loss, nitrogen (N) phosphorus (P) mineralization E. faster than C. first 180 days, but whole period, constant was higher decipiens. There no...
Phytoliths, as a newly developing plant proxy, have broad application prospects in paleoclimate and paleoethnobotany. However, the shortage of studies regarding tropical-subtropical plants topsoil phytoliths interferes with research progress on primitive humanity's utilization resources region. This focuses subtropical mountainous region monsoon climate low latitudes Southwest China to conduct phytolith morphology analysis living phytolith/pollen assemblages reveal indicative significance...
Abstract Humus is an important component of soil organic matter, but little attention has been paid to humus in newly shed litters. Moreover, the influence climatic factors and chemical composition on variation carbon ( HC ) among different litter components foliar plant functional types unknown. We conducted a field experiment subalpine forest eastern Tibetan Plateau southwestern China from April 2016 November 2016. Sixty collectors were fixed at three sampling sites that had randomly...
Appropriate nitrogen (N) fertilization in vegetable-maize rotations is effective improving agricultural production and mitigating environmental impacts to ensure sustainable food security. The dynamic sustainability of crop yields, root biomasses, accumulations sequestration rates soil organic C (SOC) total N (STN) were explored analyzed under four application (kg ha−1 year−1): 0 (Control), 285 (Low-N), 480 (Medium-N), 720 (High-N). Low-N Medium-N applications increased Chinese cabbage yield...
The initial carbon (C) quality of plant litter is one the major factors controlling decomposition rate and regulating C sequestration, but a comprehensive understanding still lacking. Here, we used proximate analysis 13C nuclear magnetic resonance (NMR) with spectral editing techniques to quantify variations in for four dominant species (fir: Abies faxoniana Rehd. et Wils.; spruce: Picea asperata Mast; willow: Salix paraplesia Schneid; rosa: Rosa omeiensis Rolfe.), including organic...
