“…The global occurrence, high accumulation rates and a wealth of microfossils and biogeochemical tracers of lake and wetland sediments allow developing the past environmental change history of sub-decadal to millennial scales. This can place the present-day observed change into the context of long-term natural environmental variability, and provides a potential means for the investigation of the interactions between past climatic dynamics and anthropogenic activities, in the absence of long-term instrumental monitoring programmes (Moser et al, 2019;Bao et al, 2023).…”

“…However, it is not a renewable resource in the short term, and its exploitation has led to a rapid decline in availability. Consequently, some countries have had to resort to imports, resulting in a significant increase in the price of peat [3][4][5][6][7]. Moreover, the extensive use of peat has caused environmental issues such as imbalances in wetland ecosystems and an amplified greenhouse effect.…”

Chrysanthemums (Chrysanthemum × morifolium) are highly valued for their ornamental and economic benefits. However, the commonly used growing medium for chrysanthemums, peat, is not renewable, and peatlands are facing depletion. Therefore, it is important to find sustainable alternatives to peat. This study aims to evaluate the potential of rice husks and leaf mold mixed with peat and perlite in different ratios (10–20–30–40–80% v/v/v/v) as substitute materials for peat in chrysanthemum production. The study examines the physical and chemical properties of the different growing media ratios, as well as their effects on plant growth, development, and physiological indicators. The results of the experiment demonstrate that the different ratios of the cultivation substrate significantly influence the physical and chemical properties of the growing medium, as well as the growth and physiological indicators of chrysanthemums. A 20–30% proportion of rice husks and leaf mold promotes the growth and photosynthetic activity of chrysanthemum cuttings, resulting in increased plant height, leaf area, total chlorophyll content, and net photosynthetic rate. The mixed substrates (10–40%) maintain suitable pH levels, electrical conductivity (EC), and nutrient content (nitrogen, phosphorus, and potassium). However, an 80% ratio of rice husks negatively affects plant survival and growth due to elevated EC and potassium levels. In conclusion, a peat medium containing 20% rice husks and leaf mold provides a more favorable cultivation substrate for producing high-quality chrysanthemums while promoting sustainable horticultural practices.

Peatlands records can be used to reconstruct and understand the history of environmental evolution, as well as a more accurate reflection of human activities. The black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are ideal natural archives of anthropogenic activities. To identify the information of anthropogenic activities recorded by peatlands in the middle and high latitudes of the alpine mountains in the arid and semi-arid regions of China. this study analyzed the concentrations of BC, δ13C ratios of BC, PAHs, and molecular diagnostic ratios of PHAs (including Benzo(a) anthracene (BaA), Chrysene (Chr), fluoranthene (Flt), anthracene (Ant), phenanthrene (Phe), Benzo(a) pyrene (BaP), and pyrene (Pyr) in a 30-cm peat profile from the Altay Mountain, northwestern China. Our results revealed concentrations of BC from 11.71 to 67.5 mg·g−1, and PAHs from 168.09 to 263.53 ng·g−1. The δ13CBC value ranged from − 31.37 to − 26.27‰, with an average of − 29.54‰, indicating that the BC mainly comes from biomass combustion. The ratios of BaA/(BaA + Chr), Flt/(Flt + Pyr), and Ant/(Ant + Phe) exceeded 0.35, 0.5, and 0.1, respectively, revealing that the PAHs pollutants mainly originated from the combustion of biomass and fossil fuel burning. Furthermore, based on these findings and our knowledge of social development in Altay, industrial transport and tourism have influenced the emission, transport, and deposition of BC and PAH in peatlands in the Altay mountains since the 1980s. After 1980, pollutant concentrations decreased with the implementation of environmental policies. The results not only reveal the influence of anthropogenic activities on the sedimentary characteristics of peatlands in the Altay Mountains, but also provide an important theoretical basis for the conservation of fragile mountain peatlands.
