Anammox process has attracted attention due to its excellent nitrogen removal properties in nitrogen-rich wastewater treatment. However, there were some obstacles for the application of anammox treat high saline sensitivity salinity. In this study, Fe(III) addition strategy was developed assist adapt surroundings, with defense mechanism involved Fe(III)-assisted emphasized. Nitrogen performance deteriorated at 3.5% salinity, average total rate 0.85 kg/(m3·d) observed. The continuous could...
As eco–environmental effects have become important considerations in the construction and planning of production, living, ecological spaces, we used a combination quantitative qualitative methods to analyze effects’ spatiotemporal evolution present appropriate ideas for restoration based on land use data. The results show that during research period both an improvement degradation regional eco–environment occurred simultaneously. In earlier period, environment tended be worse, while later...
The urban ecological environment is crucial to the quality of life residents and sustainable development region, assessment prediction can provide a scientific guidance for management improvement. We proposed novel approach assess simulate using Geographic Information System Ecological Index (GISEI). First, we calculated remote sensing index (RSEI) Xi’an in 2020. Second, selected land use data, mean annual temperature, relative humidity as indicators. regressed these indicators on RSEI...
Food security plays an important role in maintaining national stability and sustainable development of human society, its research has become a hot issue at present. Shandong is the main grain producing area China, production food security. Accordingly, this paper based on county climate change, yield, sown area, fertilizer use, total power rural machinery, population data Province from 1995 to 2020. The evolution process pattern was studied by methods spatial analysis comprehensive...
This paper focuses on county-level grain production and food security in North China; selects 17 indicators from both climatic conditions human activities; applies yield fluctuation coefficients, spatial econometric modelling, the random forest method, factor analysis to study characteristics of China influencing factors; evaluates situation based capacity. The following results were obtained: (1) temporal changes located 2000 2020 are obvious. output maintains fluctuating growth at a rate...
With global warming, the frequency of drought in China is gradually increasing. The study characteristics and its impact on crop yield great significance to ecological construction food security. Based SPEI index Xinjiang from 1961 2020, changing their responses meteorological three kinds crops (cotton, wheat corn) were analyzed. results revealed that exhibited a decreasing trend. Drought occurred less during 1961–1996 mainly 1997–2020. annual variation trend decreased regionally, arid...
The Ms ≥ 8.0 strong earthquakes occurring in Chile since 1800 were analyzed using the ternary, quaternary, and quinary commensurability methods butterfly structure diagram, it was believed that earthquake signal 2014 is relatively strong, a large likely to occur 2014. An analysis of spatial epicenter migrations showed longitudinal latitudinal have symmetry synchronism, there five obvious northward four southward migrations. axis at about 71. 7° W 30° S; these axes are located subduction zone...
Suffering from the double blow of new crown pneumonia epidemic and floods, food security issues have once again become a source concern. Eastern Gansu is an important dry farming area in northwestern China, agricultural production has been greatly affected by climate change. Based on data 17 national meteorological stations eastern 1961 to 2020 population, grain planting each region 1986 2019, using Thornthwaite Memorial model, this paper analyzed potential (TSPV), population carrying...
The aim of this study was to provide a scientific basis for unified standard the reference value healthy presenile human hematocrit in China. We studied relationship between values hematocrit, tested according Wintrobe's laws, and five geographical factors. It found that altitude is most important factor affecting hematocrit. As gradually increases, also increases. quite significant. By using method stepwise regression analysis, two multivariate equations were deduced: Y1 = 39.7 + 0.00328X1...
Abstract Flood risk assessment is a critical aspect of flood management. The historical disaster statistics method and the index system are commonly employed for this purpose. In study, we combine these approaches to assess flooding in Hubei province, China. Our methodology includes compiling data from 1949 2000 calculate extent trend each geographic unit, hazard assessed using aspects. Additionally, also select relevant indicators such as elevation difference, distance water bodies, GDP,...
Revealing the spatial distribution and regional differences of red blood cell width (RDW) reference values in healthy Chinese population is important for monitoring, diagnosis prevention top chronic diseases disease spectrum China. Medical indicator data were matched with geographical environmental pollution to predict RDW whole region China using ridge regression analysis, support vector machine BP neural network. Taylor diagrams assignment methods used select optimal model, was mapped...
Flood risk assessment is an important aspect of flood management, and we combined the historical disaster statistics method with index system to assess in Hubei Province, China. Our methodology includes collecting data hazard by calculating degree trend from disasters each geographical unit. Meanwhile, selected relevant indicators such as elevation difference, distance water body, gross domestic product (GDP), population, proportion construction land measure susceptibility, weights for these...
