Abstract Western Jilin Province is one of the world's three major saline–alkali land distribution areas, and also an important area global climate change carbon cycle research. Rhizosphere soil microorganisms enzymes are most active components in soil, which closely related to can reflect organic (SOC) dynamics sensitively. Soil inorganic (SIC) main existing form pool arid land, its quantity affects pattern accumulation storage. Previous studies mostly focus on SOC, pay little attention SIC....

Western Jilin province has the most serious area of soda salinization in Northeast China, which affects and restricts sustainable development agriculture. The effects physico-chemical properties rhizosphere non-rhizosphere soil on microbial diversity enzyme activities (polyphenol oxidase, catalase, invertase, amylase) were evaluated typical saline-alkali paddy field. Community-level physiological profile (CLPP) based Biolog-ECO plates was used to assess functional microorganisms....

Irrigation regime and fertilizer nitrogen (N) are considered as the most effective agricultural management systems to mitigate greenhouse gas (GHG) emissions from crop fields, but few studies have involved saline–alkaline paddy soil. Gas emitted fields (1-year-old 57-year-old) was collected during rice growing seasons by closed chamber method. Compared continuous flooding irrigation, lower average CH4 flux (by 22.81% 23.62%), higher CO2 24.84% 32.39%) observed intermittent irrigation fields....

Soil organic carbon (SOC) plays a critical role in cycling and soil quality of agroecosystems. Understanding the factors influencing SOC main indicators for can help better management sustainable agriculture. In this study, we selected three upland fields (U1, U2 U3) paddy (P1, P2 P3) saline-alkali agroecosystems to study impacts physico-chemical properties (soil pH, exchangeable sodium percentage, electrical conductivity bulk density) enzyme activities amylase, invertase, catalase...

Soil organic carbon (SOC) mineralization (conversion of carbonaceous material to dioxide) plays a central role in global cycle. However, the effects SOC under different saline–alkali stress conditions are poorly understood. In order understand processes, four paddy fields with saline and alkali degrees were chosen as experimental samples soil CO2 emission fluxes at nine time steps whole simulation experiment observed. The physical chemical properties soils field compared for dynamic changes...

With regard to environmental facilities, blindness and the subjectivity of site selection lead serious economic, engineering social problems. A proper siting proposal often poses a challenge local governments, as multiple factors should be considered, such costs, construction conditions impact. How make optimal decision has become topical issue in academic circles. In order enrich framework models, this study combined GIS, AHP Remote Sensing (RS) technologies conduct suitability analysis...

Simulating the hydrological process of a river basin helps to understand evolution water resources in region and provides scientific guidance for allocation policies between different basins management within basin.

The notion of a ‘Water-saving society’ may help China achieve sustainable development and high-quality development. In this paper, the concept water resources utilization level is discussed from perspective water-saving society, an evaluation index system including 33 indicators constructed. This paper takes Jingyu County 2009 to 2018 as example verify rationality indicator study. Additionally, by changing sensitivity analysis method weights, with greater influence on results are screened...

Wastewater treatment plants play a critical role in reducing point source pollution watersheds; however, taking on the task of pollutants such as COD and NH3-N, they also consume energy intensively, which can result additional greenhouse gas (GHG) emissions operating (OAM) costs. Therefore, appropriate effluent targets should be implemented to achieve balance between load reduction, costs, depending field conditions wastewater plant. In this study, four different technologies, namely, A2/O,...

On the basis of soil environment investigation in Da'an City, Jilin Province, China, 40 samples from main land use types were obtained and tested by standard method. Soil organic matter (SOM), total N (TN), P (TP), K (TK), available (AN), (AP) (AK) chosen as evaluation factors. A regional nutrient model was developed based on matter-element model. The results show that with grade II–V respectively account for 10%, 30%, 32.5% 27.5%, those IV V 60% all samples. relationship between nutrients...

The study of greenhouse gas emissions has become a global focus, but few studies have considered saline-alkali paddy fields. Gas samples and soil were collected during the green, tillering, booting, heading grain filling stages. emission fluxes CO2, CH4, N2O as well pH, soluble salt, available nitrogen, organic carbon contents detected to reveal (GHG) laws influence factors in Overall, GHG growing season increased, then decreased, increased again peaked at booting stage. CO2 CH4 observed...

Agricultural ecosystems are important contributors to atmospheric greenhouse gasses (GHGs); however, in situ winter emission data saline-alkali fields scarce.
