In order to improve the working stability of distributed marine green energy resources grid-connected system, we need the big data information mining and fusion processing of grid-connected system and the information integration and recognition of distributed marine green energy grid-connected system based on big data analysis method, and improve the output performance of energy grid-connected system. This paper proposed a big data analysis method of distributed marine green energy resources grid-connected system based on closed-loop information fusion and auto correlation characteristic information mining. This method realized the big data closed-loop operation and maintenance management of grid-connected system, and built the big data information collection model of marine green energy resources grid-connected system, and reconstructs the feature space of the collected big data, and constructed the characteristic equation of fuzzy data closed-loop operation and maintenance management in convex spaces, and used the adaptive feature fusion method to achieve the auto correlation characteristics mining of big data operation and maintenance information, and improved the ability of information scheduling and information mining of distributed marine green energy resources grid-connected system. Simulation results show that using this method for the big data analysis of distributed marine green energy resources grid-connected system and using the multidimensional analysis technology of big data can improve the ability of information scheduling and information mining of distributed marine green energy resources grid-connected system, realizing the information optimization scheduling of grid-connected system. The output performance of grid connected system has been improved

The power industry is a major fossil fuel consumer in China, with large amounts of CO₂ emissions released from the production process of the power industry. To decrease CO₂ emissions, it is practical to start by analyzing its influencing factors in the power industry. This paper identified five influencing factors of CO₂ emissions through the extended STIRPAT model, including GDP, urbanization level, electric power structure, industrialization level, and power-consumption efficiency. According to the projection pursuit model, 30 provinces in China were divided into 4 categories based on the average of all the best projection values. Results indicate that there were positive correlations between the five influencing factors and CO₂ emissions – especially per capita GDP, power-consumption efficiency, and urbanization level. The impact of industrialization level and electric power structure on CO₂ emissions fluctuated greatly. The regional features of the each type were analyzed and policy implications proposed.

Planting rice (OryzasativaL.) is an effective and feasible approach for improving salt-affected soils, especially in saline-sodic soils. Improved rice is the main biological measure for rapid treatment and utilization of a saline-sodic paddy field. Reasonable application of nitrogen fertilizer is an important measure for obtaining saline-sodic soil high yield. Dongdao 4 (D-4), Dongdao 2 (D-2), Changbai 9 (C-9), and Baijing 1 (B-1)) were studied by a field experiment in this paper. On the growth, yield, and yield component responses of different nitrogen levels (150 kg N/ha, 225 kg N/ha and 300 kg N/ha), and the nitrogen uptake of four saline-tolerant rice cultivars at different nitrogen application levels was calculated, which provided a useful reference for the rational application of nitrogen fertilizer in a salinesodic paddy field. The results showed that: biomass of four kinds of rice accumulates over time and reached their maximums in September, with the biomasses of D-2 and D-4 reaching the maximum of 225 kg N/ha, and C-9 and B-1 reaching the maximum at 300 kg N/ha, which is related to rice varieties; the yields of four salt-tolerant rice plants reached the highest in 150 kg N/ha; applied nitrogen fertilizer reasonably was beneficial to increase the number of spikes and the number of effective grains per spike, in this experiment, the optimum amount of nitrogen is 150 kg N/ha, and the number of spikes and the number of effective grains per spike also were major factors in increasing production. With 1000-grain weight, primary and secondary branches made no significant contribution to the yield; the N uptake of four kinds of rice gradually increased over time and reached the maximum in September. There was no significant difference in the nitrogen grain production efficiency of 4 rice varieties under different nitrogen application rates; with the increase of nitrogen application rate, partial productivity of nitrogen fertilizer nitrogen of 4 rice varieties all decreased. Therefore, reasonable application of nitrogen fertilizer promoted the uptake and transfer of nitrogen to the plant.

This research was undertaken in order to determine and analyze various heavy metals present in sediments taken from Lake Donghu. Six heavy metals: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), and zinc (Zn) were determined by inductively coupled plasma-atomic emission spectroscopy (ICPAES). Relative enrichment factors and potential ecological risk indexes were used to study the pollution status of heavy metals in sediments and assess their potential ecological risk to the environment. Sediment enrichment factors of heavy metals were found in the following order Cr > As > Cd > Zn > Cu > Pb. Potential ecological risk indices for heavy metals were: Cd > As > Cr > Cu > Pb > Zn. The calculated potential ecological risk indices showed that the lake was polluted by heavy metals. Cd had moderate potential ecological risk to the ecological environment and was the main contributor to potential toxicity response indices for various heavy metals in Lake Donghu. Analysis of variance (ANOVA) was used to establish the significance of variations in heavy metals. The mean seasonal concentrations of metals showed that there were significant differences among seasons and sampling sites (P<0.05). The cause of pollution in Lake Donghu could be associated with industrial and human activities. We proposed strategies that can be applied in order to prevent accumulation of heavy metals in the lake.

Plants exhibit resistance to incompatible pathogens by localized and systemic defense responses. In this study, a proteomics approach was used to study compatible and incompatible interactions between wheat and Puccinia striiformis f. sp. tritici (Pst). Seedlings of wheat cv. Suwon 11 were inoculated with isolates of compatible race CYR31 and incompatible race CYR23. Total proteins isolated from wheat leaves were separated by two-dimensional gel electrophoresis. Compared with the mock inoculation, 41 differentially expressed proteins at 24 and 72 h post-inoculation were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and 23 of these proteins were positively identified. Of those, six were further examined for changes at the transcriptional level in wheat leaves infected with Pst. They were categorized into classes related to photosynthesis, antioxidant defense, signal transduction, and metabolism. Annotation of proteins induced in incompatible interactions revealed a rapid resistance response that included the induction of protein kinase signaling and the production of reactive oxygen species, which usually occur during R-gene-mediated responses. Proteins with antioxidant functions, e.g., ascorbate peroxidase, dehydroascorbate reductase, and glutathione S-transferase, were differentially expressed between compatible and incompatible interactions, indicating differential accumulation of reactive oxygen species in infected tissues. In addition, fragments of ribulose-1, 5-bisphosphate carboxylase/oxygenase (Rubisco) were identified in proteins isolated from Pst-infected leaves. Rubisco fragmentation in response to Pst inoculation was confirmed by western blot analysis, indicating that chloroplasts and photosynthesis in both the incompatible and compatible situations were affected by Pst infection.

Suspension cells of Panax ginseng C.A. Meyer were cultivated in 3-L balloon-type bubble bioreactors and the bioreactor with the angle of 90º at the bottom side was optimized. The gaseous composition in plant cell and tissue cultures is regarded as an important factor affecting the plant growth. Gas hold-up was remarkably higher in the bioreactor with an angle of 90º than the other ones. Aeration rates impacted on the growth ratio, the specific O2 uptake rate (SOUR) of ginseng cells were investigated. 0.4 vvm was selected as the optimal aeration rate with a dry weight of 6.45 g L-1. The specific O2 uptake rate in the culture time was detected and reached the top value at the maximum growth ratio.

Nansi Lake, a typical shallow and macrophyte-dominated lake in south Shandong Province, China, has a total surface area of 1,266 km2 and is the largest and most important freshwater reservoir in northern China for the eastern route of the South-North Water Diversion (SNWD) project, in which the water in Yangtze River will be transported more than 1,100 km from Yangzhou to Tianjin and Beijing. A water-level fluctuating zone (WLFZ) near Nansi Lake will be formed when the SNWD project begins to transport water flowing through the lake. Phosphorus fractions and adsorption-release characterization for soil samples from four typical lands (reed, wood, maize, and soybean) were conducted to investigate soil phosphorus stability. In addition, a soil submerged experiment was performed to simulate phosphorus release under submerged conditions. Phosphorus adsorption-desorption equilibrium concentrations (CEPC) of four lands were 0.006, 0.089, 0 .110, and 0.287 mg L-1, respectively, which means that maize, soybean, and woodland had higher potentials than reed land for phosphorus releasing to the overlaying water. Submerged experiment results showed that the quantities of p hosphorus released from reed, wood, maize, and soybean soils were -0.14, 0.06, 0.12, and 0.97 mg kg-1, respectively. Soils in the reed land adsorbed phosphorus from overlying water, but the other soils released phosphorus into the water. Thus, in order to decrease the phosphorus releasing quantity from the wood, soybean, and maize land under the conditions of submerged lands at water diversion time, the land uses of wood, soybean, and maize should be switched to land for planting reed.

Diurnal changes in the structure of the ciliate community in surface waters were studied in the aquaculture area of Dapeng’ao cove, China. Two periods of heavy rainfall occurred during the study period, intensifying water column stratification and influencing the water’s properties. A total of 21 ciliate taxa from 15 genera were identified; the dominant species was Mesodinium rubrum. The maximum abundance of M. rubrum reached 3.92×104 indiv. dm−3, contributing 95.1% (mean value) to the total ciliate abundance. Diurnal changes in M. rubrum abundance were highly variable, the driving force probably being irradiance and food availability. The results suggest that M. rubrum may form blooms in aquaculture areas when there is a suitable physical regime with enriched nutrients, which is potentially harmful to the fish-farming industry.

The objective of this study was to test whether haem oxygenase-1 (HO-1) is involved in hydrogen peroxide (H₂O₂)-induced lateral root (LR) formation. The results showed that 0.1 mM H₂O₂ mimicked the effects of the HO-1 inducer, haemin, on the up-regulation of tomato HO-1 (SlHO1) expression, increased carbon monoxide (CO) synthesis and LR formation. However, 1.0 mM H₂O₂ resulted in inhibitory responses. The above inducible or inhibitory responses elicited by 0.1 and 1.0 mM H₂O₂ were noticeably blocked or rescued by the HO-1 inhibitor zinc protoporphyrin IX (ZnPP) or haemin, and then separately reversed by CO or ZnPP. Further trials showed that haemin-induced responses were not altered by the H₂O₂ trap, dimethylthiourea (DMTU). When applied alone, DMTU not only decreased H₂O₂ contents but also inhibited SlHO1 expression and LR development. These responses were recovered by the application of haemin or CO. Molecular evidence revealed that H₂O₂-modulated expression of the target genes responsible for LR formation was blocked by ZnPP, but rescued by CO. Salinity-induced up-regulation of HO-1 expression and thereafter LR formation were also dependent on the H₂O₂ generation. Overall, these results demonstrated a possible role of HO-1 in the H₂O₂-induced tomato LR formation.
