Partition-coordinated control of soil and water loss for chestnut forests in the Yanshan Mountain Region, China

引用

International Journal of Sediment Research 2019年第1期34卷 58-64页

作者： Xinhui Ding Guangquan liu xiaoying liu Yongsheng Xie Zhichun Yue China Institute of Water Resources and Hydropower Research State Key Labof Water Recycle Modeling International Research and Training Center on Erosion and Sedimentation Institute of Soil and Water Conservation Chinese Academy of SciencesMinistry of Water Resources State Key Laboratory of Hydraulic Engineering Simulation and Safety Tianjin University

Soil erosion from chestnut forests is one of the most important factors causing land degradation in the Yanshan Mountain Region. A 2-year field study was done to compare the effects on erosion of a control plot(CP), a repaired and maintained horizontal ditch built with an engineering baffle every 6 m(MP 1),and a repaired and maintained horizontal ditch built with an engineering baffle every 8 m(MP 2). The results showed that the slope runoff of chestnut forests was influenced by rainfall characteristic *** single rainfall characteristic factor showed dominance for hill slope runoff. The runoff reduction effect of the partition-coordinated erosion control measures(MP 1 and MP 2) was substantial for chestnut forests under high rainfall intensity conditions. However, the runoff reduction efficiency was higher under the conditions of heavy rainfall and low average rainfall intensity than for storms with higher intensity and lower total rainfall. The reduction effect of the partition-coordinated erosion control measures on the runoff and sediment yield of chestnut forest slopes was MP 2 > MP 1 > CP. The runoff reduction rate and erosion reduction rate of MP 2 reached 61.70% and 97.41%, respectively, and that for MP 1 was 54.15% and 85.31%, respectively. Therefore, after a comprehensive comparison, MP 2 was determined to be more effective for soil erosion control for a sloping chestnut forest.

Arbuscular Mycorrhizal Fungi in Wetland Habitats and Their Application in Constructed Wetland: A Review

引用

Pedosphere 2016年第5期26卷 592-617页

作者： XU Zhouying BAN Yihui JIANG Yinghe ZHANG Xiangling liu xiaoying School of Civil Engineering and Architecture Wuhan University of Technology School of Chemistry Chemical Engineering and Life Sciences Wuhan University of Technology

Over the last three decades, the presence and functional roles of arbuscular mycorrhizal （AM） fungi in wetland habitats have received increasing attention. This review summarized the mycorrhizal status in wetlands and the effect of flooding on AM fungal colonization. Plants of 99 families living in 31 different habitats have been found to be associated with AM fungi, even including submerged aquatic plants and several plant species that were thought to be nonmycorrhizal （Cyperaceae, Chenopodiaceae, and Plumbaginaceac）. The functions of AM fungi in wetland ecological systems could be concluded as their influences on the composition, succession, and diversity of the wetland plant community, and the growth and nutrition of wetland plants. Affecting the composition, succession, and diversity of the wetland plant community, AM fungi have positive, negative, or neutral effects on the performance of different wetland species under different conditions. The factors that affect the application effect of AM fungi in constructed wetland （CW） include flooding, phosphorus, plant species, aerenchyma, salinity, CW types, operation modes of CW, and wastewater quality. The generalist AM fungi strains can be established spontaneously, rapidly, and extensively in wastewater bioremediation technical installations; therefore, AM fungi can be considered ideal inhabitants of technical installations for the plant-based bioremediation of groundwater contaminated by organic pollutants or other contaminants. In the future, roles of AM fungi and factors that affect the purifying capacity of AM-CW system must be understood to optimize CW ecosystem.

Intensive selective breeding for high growth rate and body weight cause excess abdominal fat in *** microbiota and folic acid were reported to regulate lipid metabolism.A total of 210 one-day-old broilers were divided into the control(folic acid at 1.3 mg/kg)and folic acid groups(folic acid at 13 mg/kg)to illustrate the effects of folic acid on growth performance,abdominal fat deposition,and gut microbiota,and the experiment lasted 28 *** revealed that dietary folic acid addition decreased abdominal fat percentage(P<0.05)and down-regulated genes expression related to cell proliferation and differentiation in abdominal fat including IGF1,EGF,C/EBPα,PPARγ,PLIN1,FABP4 and PCNA(P<0.05).Folic acid addition decreased caecal Firmicutes-to-Bacteroidetes ratio(P<0.01)and increased the proportions of Alistipes,Oscillospira,Ruminococcus,Clostridium,Dehalobacterium and Parabacteroides(P<0.05).Caecal acetic acid,and propionic acid contents were found to be higher under folic acid treatment(P<0.05),which were negatively related to genes expression associated with adipocyte proliferation and differentiation(P<0.05).Ruminococcus was positively correlated with caecal acetic acid content,and the same phenomenon was detected between propionic acid and Oscillospira and Ruminococcus(P<0.05).Acetic acid and Oscillospira were identified to be negatively associated with abdominal fat percentage(P<0.05).In conclusion,our data demonstrated that dietary supplementation of folic acid reduced fat deposition in broilers by inhibiting abdominal adipocyte proliferation and differentiation,which might be mediated by changes in gut microbiota and short chain fatty acid production.
