“…Therefore, sediment dredging is very necessary. The second stage in improving water quality could be (1) managing the breeding of sh such as Hypophthalmichthys molitrix, bighead carp and Carassius auratus cuvieri to uptake algae; 54,55 (2) cultivating aquatic plants to absorb the nutrient sources and eliminate algal bloom; 56,57 and (3) scheduling lake water utilization to maintain a higher water elevation and mobility to increase the DO level and avoid sediment frost boil.…”

“…Further, Nitrogen (N) and Phosphorus (P) elements are determinant nutrients for plant growth and aquatic ecosystems functioning (Elser et al ., 2007) and their mass ratio can potentially affect plant-mediated ecological processes (Zechmeister et al ., 2015). Soil C: N: P ratios can directly reflect soil fertility and indirectly the nutritional status of plants and species composition of plant communities (Mao et al ., 2016). Carbon, nitrogen, and phosphorus biogeochemical circulations closely related to the soil’s ecological structure, processes, and functions in wetland ecosystems (Hansson et al ., 2005).…”

Ecological stoichiometric should be incorporated into management and nutrient impacted 32 ecosystems dynamic to understand the status of ecosystems and ecological interaction. The present study 33 focused on ecological stoichiometric characteristics of different macrophyte plants soil, leave, stem and root 34 after the removal of seine fishing since 2000 from Shengjin Lake. For C, N and P analysis from leaves, stems, 35 roots and soil to explore their stoichiometric ratio and deriving environmental forces here four dominant plant 36 communities (Zizania caduciflora, Vallisineria natans, Trapa quadrispinosa and Carex schmidtii) were 37 collected. C, N, P and C: N: P ratio in leafs, stems, roots and soil among the plant communities vary and the 38 studied plant communities had significant effect on the measured variables. There was high C: N in 39 C.schmidtii soil (7.08±1.504) but not vary significantly (P >0.05), and N: P ratio measured high in V. natans 40 (13.7±4.05) and C: P in T.quadrispinosa soil (81.14±43.88) and showed significant variation (P<0.05) 41 respectively. High leaf C: N and N: P ratio was measured in C. schmidtii and V. natans respectively. 42Nevertheless, high leaf C: P ratio was measured in Z.caduciflora. From the three studied organs leafs C: N, 43 N: P ratio showed high values compared to root and stems. The correlation analysis result showed that, at 0-44 10cm depth ranges SOC correlated negatively with stem total phosphorus (STP) ,and RTN (P<0.05) but 45 positively strongly with LTP and LTN (P<0.01) respectively. Soil total nitrogen at 0-10cm strongly positively 46 correlated with LTP (P<0.01) and positively with RN: P and LTC (P<0.05). Soil basic properties such as 47 SMC.BD and pH positively correlated with soil ecological stoichiometric characteristics. Redundancy 48 analysis (RDA) result showed pH and available phosphorus were the potential determinant of soil 49 stoichiometry. 50 51 52 53 54 55 56 57 58 Keyword: Wetland plants, Ecological stoichiometry, Shengjin Lake, Environmental variables. 59 60 61 62 63 64 3 65 66 Introduction 67 Ecological stoichiometry is an important tool for studying ecological processes and functions (Shang B et 68 al., 2018). Besides, it uses to explore the dynamic balance of various elements and their interactions (Moorthi 69 S D et al., 2016) and limitation of plant growth (Chen et al., 2016). Carbon (C), Nitrogen (N) and phosphorus 88 community type (Shang et al., 2013) can determine these nutrients and in turn it can be used for the 89 accumulation and allocation of plant biomass (Lie and Li, 2016). Because of human interference (Sardans 90 and Penuelas, 2014), climate change, hydrological fluctuation, aquatic and offshore environment wetlands 91 have been greatly affected. This is posing great impacts on vegetation and ecosystems (Qin et al.2014). C: N 92 and N: P ratio can be used as effective indicators for the health conditions and growth status of plants (Vrede 93 et al., 2004; Hessen et al., 2007) and understating the life strategies of plants (Wu ...

“…Among the most significant elements to be examined in plants are nitrogen (N) and phosphorus (P), two macronutrients involved in the synthesis of carbohydrates, lignin, cellulose, proteins and other essential compounds (Xia et al 2014). Their concentrations and ratios are effective indicators of plant nutrient use and growth (Herbert et al 2003, Mao et al 2016.…”

Plant nutrient stoichiometry is affected by both environmental factors and plant physiological processes. However, we know little about how small elevation gradients (influencing e.g. flooding regimes) and seasonality combine with soil physicochemical properties to influence nutrient stoichiometry in wetland plants. In this study, we examined these factors in Carex brevicuspis at Dongting Lake, China, during the non‐flooding periods in March, May and December of 2015 and February of 2016. We found that total foliar C concentration increased as elevation increased, especially during December 2015 and February 2016. At the low‐elevation site, total foliar C concentration decreased over the season, whereas it first increased and then decreased over time at higher elevations. Foliar total N and P concentrations decreased from March to May and subsequently increased throughout the season, and these concentrations were always much higher at the low‐elevation site. The C:N and C:P ratios first increased and then decreased over the season, while increasing with rising elevation. The N:P ratio was lower at the low‐elevation site, especially during May 2015 and February 2016; its variation over time differed across the elevations. A canonical correspondence analysis revealed that soil organic C, total N and soil nitrate N are important for determining C. brevicuspis stoichiometry. Our results suggest that both elevation and plant life stage have a significant influence on plant stoichiometry. This study improves our understanding of the seasonal dynamics of plant nutrients under different geographical conditions.
