Abstract Soil microorganisms are critical to soil health and environmental functions; however, the dynamics of microbial communities their response variables following conversion desert soils oasis farmland have not been well documented. We used high‐throughput pyrosequencing investigate along an irrigated cultivation chronosequence (cultivated for 16, 33, 45 60 years) in adjacent non‐cultivated a desert‐oasis ecotone northwestern China. Additionally, we explored which may be responsible...
Soil nitrification and denitrification are key nitrogen (N) removal processes in riparian wetlands extremely arid regions, but the driving factors of two N these still unclear. We measured soil rates related environmental properties a typical wetland middle reaches Heihe River, northwestern China. Our results showed that exhibited moderate variability, ranging from 52.77 to 221.18 μg kg−1 h−1 91.25 428.26 h−1, respectively. salinity was high, with mean electrical conductivity (EC) 6.8 mS...
Harmful cyanobacterial blooms in eutrophic water bodies pose a major threat to the environment and human health. The morphological functional traits of cyanobacteria play important roles maintaining their competitive advantages. To explore regulatory mechanisms different bloom-forming cyanobacteria, we performed one-year-long phytoplankton survey from November 2016 October 2017 Lake Chaohu, China. colony size cell diameter dominant were measured, relationships analyzed. results showed that...

<b><sc>Abstract.</sc></b> <b>For a sprinkler system, water losses through the wind drift and evaporation as well interception loss were usually considered main problem. Canopy part of has great influence on use efficiency analysis for irrigation system. A study was conducted to determine alfalfa canopy its factors. three growth stages (S<sub>1</sub>- Early vegetative stage, S<sub>2</sub>-Late stage S<sub>3</sub>- Bud stage) measured under two kinds low-pressure spray sprinklers.

寡—中营养型水体中，虽然营养盐水平偏低，但仍会偶发性出现较为严重的蓝藻水华现象，其具体机制仍有待深入探索研究. 本研究以偶发水华水体方便水库为例，通过历史数据分析和调查研究，探讨了其水华蓝藻的优势类群，并分析了蓝藻水华形成的主要驱动因素. 研究发现：方便水库优势的水华蓝藻为浮丝藻和长孢藻，这两种丝状蓝藻是发生偶发性蓝藻水华的潜在风险物种，其中浮丝藻的发生风险最高，风险时段为7—9月. 方便水库多年来营养盐浓度呈现下降的趋势，其中总氮浓度的下降趋势快于总磷浓度，整体有利于蓝藻水华的防控，但是营养盐的波动，尤其是随着降雨导致的地表径流入库对水体总磷的脉冲式补充，降低了水体氮磷比，增加了水库偶发蓝藻水华的风险; 在营养盐满足的条件下，水温、高锰酸盐指数和氧化还原电位是发生浮丝藻水华的主要驱动因素，氧化还原电位、水温和透明度是发生长孢藻水华的主要驱动因素. 本研究结果有助于提升对偶发性蓝藻水华机制的认识和应急处置工作的精准性.;Although sporadic cyanobacterial blooms have been reported in many oligo-meso...
