To reveal the litter water-holding capacity of typical forest in Mopan mountain in central Yunnan Plateau, in this study, the litters of five typical forest types, namely Pinus armandii (PA), Pinus yunnanensis (PY), Quercus semecarpifolia (QS), Keteleeria evelyniana (KE), and evergreen broad-leaved (EB) forest were selected as research objects. The water-holding capacity of different forest litters were analyzed by the field investigation and indoor soaking experiment. The results showed that, (1)the total biomass of five typical forests litter were ranged from 26. 46 t/ hm2 to 69. 83 t/ hm², with the largest biomass in EB; and the biomass of different decomposition layers from large to small showed: DL, SL, and UL. (2) The average maximum water-holding rate (395. 94%, 370. 89%) and effective water storage rate (275. 91%, 266. 90%) of EB and KE were significantly lower than those of other forest, and the maximum water-holding capacity (24. 82 t/ hm², 23. 33 t/ hm²)and effective storage capacity (17. 04 t/ hm², 17. 08 t/ hm²) of EB and PY were higher than those of other forest. The maximum water holding capacity and effective storage capacity of litter layer of five forest increased with the increasing of decomposition degree in different decomposition layers. (3)The power function relation were found between water loss rate and air-drying time in different forest litters, and the lowest water loss rate and the best water-holding capacity were found in EB among five forests.

Vegetation coverage is an important indicator to reflect the ecological environment status of the lower Yellow River floodplain and its changes mirror natural evolution and the effect of human activities on the ecological environment. The county-level administrative area involved in the wide beach area of the lower Yellow River was used as the research area, and the seven periods of Landsat in 1987, 1994, 1998, 2003, 2008, 2013 and 2017 were used as the remote sensing data source. It used the pixel dichotomy method based on the NDVI index to obtain vegetation coverage and classification. It used the methods of univariate linear trend analysis, transfer matrix method, center of gravity transfer model and correlation analysis to analyze the spatial and temporal changes of vegetation coverage in the study area and the influencing factors. The results show that the overall vegetation coverage in the broad beach area of the lower Yellow River and along the area has shown an overall improvement trend in the past 30 years. The gap between the vegetation coverage in the beach area and the vegetation coverage in the coastal administrative areas are gradually decreased after 2003, and it achieves an overtake in 2017. The annual change of vegetation coverage presents an obvious “bimodal” characteristic. The channel contraction and the development of urbanization have an important impact on the inter-annual changes in vegetation coverage. [ABSTRACT FROM AUTHOR]

In order to analyze the spatial-temporal variation along the wide floodplain of the Lower Yellow River, using Landsat time-series data, the temporal and spatial changes of grass wetland habitats along the wide floodplain of the lower Yellow River of 2000 and 2015 were interpreted by utilizing the modification of normalized difference water index method. The disturbing factors of grass wetland habitats were analyzed in conjunction with the activities of water and sediment along the Yellow River channel. The results show that from 2000 to 2015, the habitat area of grass wetland along the beach area has been decreased and grass wetland habitats tend to migrate downstream. At present, the upstream runoff is concentrated, and the peak value of the corresponding hydro logical pulse is as high as nearly 3 meters, which is not conducive to the stable succession of wetland habitat vegetation along the beach area. In addition, human activities such as agricultural cultivation and sand digging along the beach area also seriously affect the stable development of grass wetland habitats. Based on the analysis of the water and sediment activities along the beach area, the total area of grassland wetland habitats along the Yellow River floodplain area is 247.41 km², accounting for only 9.01% of the total area of the wide beach area.

Considering the problem of civil and military integration pre-decision evaluation for military information system projects, an improved AHP and cloud model based civil and military integration demand degree evaluation model for military information system projects is proposed, which explored a new approach to study the civil and military integration evaluation work. The normal interval number is used to express the evaluation data, and then the interval number backward cloud generator is used to generate the cloud model of each evaluation indicator. Finally the normal cloud model integrated similarity measure method based on shape and distance is used to comprehensively evaluate the civil and military integration demand degree. The simulation experiment results show that the proposed evaluation model is reasonable and feasible. [ABSTRACT FROM AUTHOR]

In order to study the effects of loading age on the creep behavior of steel tubular columns filled with compound concrete made of demolished concrete lumps and fresh concrete, basic creep tests were performed on twelve groups of specimens. The creep coefficient-time curves and creep stain-time curves under different loading ages for each pecimen were obtained and analyzed. The effectiveness of variation of creep coefficient and different calculation methods to predict the creep strain of specimens were studied. The results show that: for both concrete-filled steel tube specimens and steel tubular column specimens filled with compound concrete, the creep coefficient increases with the increasing loading age, and the effect of loading age on the latter is less than that on the former. For the same loading age, the creep coefficient of steel tubular columns filled with compound concrete is smaller than that of the concrete-filled steel tube, and the difference between the two decreases with the loading age. The age-adjusted effective modulus method based on the Counto model is presented to predict the creep stain of specimens, and the calculated values are in good agreement with the experimental results.

In order to study the seismic behavior of monolithic precast concrete shear wall structure, a 12-story 1/5 scale monolithic precast concrete shear wall model structure was designed and constructed. The dynamic characteristics, acceleration magnification factor, floor shear and displacement, and the maximum inter-story drift were examined through a shaking table test considering three seismic waves. The cracking phenomenon was also studied in detail. The experimental study shows that after the first loading stage the natural frequency is reduced to 80% of the original frequency. With increase in PGA, the natural frequency and the acceleration magnification factor are reduced, and the floor shear is increased. In the inelastic performance stage, evenly distributed horizontal cracks are observed of the junctions between the prefabricated wall and the floor. In addition, the model structure shows evidently nonlinear behavior, where the inter-story drift ratios increase and the natural frequency decreases significantly. By examining the peak inter-story drift ratios response, it is concluded that the monolithic precast concrete shear wall structure could be used against seismic intensity 8. However, the connection performance of the prefabricated wall and the floor should be strengthened to avoid through cracks. [ABSTRACT FROM AUTHOR]
