| 2 | Modeling the Hook Depth Distribution of Pelagic Longlining in the Equatorial Area of Indian Ocean显示文摘A survey was conducted in the equatorial area of Indian Ocean for a better understanding of the dynamics of hook depth distribution of pelagic longline fishery.We determined the relationship between hook depth and vertical shear of current coefficiency,wind speed,hook position code,sine of wind angle,sine of angle of attack and weight of messenger weight.We identified the hook depth models by the analysis of covariance with a general linear model.The results showed that the wind effect on the hook depth can be ignored from October to November in the survey area;the surface current effect on the hook depth can be ignored;the equatorial undercurrent is the key factor for the hook depth in Indian Ocean;and there is a negative correlation between the hook depth and vertical shear of current and angle of attack.It was also found that the deeper the hook was set,the higher hook depth shoaling was.The proposed model improves the accuracy of the prediction of hook depth,which can be used to estimate the vertical distribution of pelagic fish in water column. | SONG Liming LI Jie GAO Panfeng ZHOU Ji XU Liuxiong | 2012 | Journal of Ocean University of China2012，11，4： | 10 |

| 5 | Using electrogeochemical approach to explore buried gold deposits in an alpine meadow-covered area显示文摘Exploration for buried gold ores and other deeply buried ores, especially in high altitude localities, is one of the tough challenges facing the geological world today.Fast and efficient ore prospecting methods are badly needed to deal with the situation. This paper documents a test that, for the first time, uses an electrogeochemical approach to prospect ores in the alpine meadow-covered Bangzhuoma area and its periphery in Qinghai–Tibet Plateau.The results were compared with conventional soil measurements from a 2 D prospection, and an ideal model of electrogeochemical anomaly formation in the area was established based on the comparison in order to provide theoretical guidance to buried ore prospecting in areas with similar conditions. The research shows that:(1) For exploration of deeply-buried mineral deposits, an electrogeochemical approach is better than soil measurements in terms of correspondence between element content values and anomaly forms and spatial distribution of known deposits in sections. Anomalies of high to low temperature element associations(Bi–Mo; Au–Ag–As–Bi and Au–Ag)and clear zonation were also observed along vertical vein runs in the sections. Based on integration of the observation with geological characteristics of the sections, we propose to use Au, Ag and As as the electrogeochemical indicators and Bi and Mo as the electrogeochemical tracing elementsto guide further analysis.(2) Judging from element statistics and the scale, intensity, and range of anomalies in plan maps, we found that an electrogeochemical approach is less affected by topography and secondary actions. The plan maps also show that elemental differentiation coefficients of the study area are in an ascending order of Ag(0.67) \ Mo(0.85) \ Bi(0.97) \ Au(1.51) \ As(2.35),better representing the element distribution in the area and yielding more striking and concentrated anomalies for known deposits than that of the soil measurements. Apart from that, electrogeochemical anomalies were observed in the south of lines 002 and 003 and the central of lines 008 and 009. We suggest the existence of deeply-buried mineral deposits based on analyses of element combinations and gold grade variations in samples taken from exploratory trenches in the area.(3) A three-stage(referring to the ore body dissolution, the mineralogenetic particle migration, and the mineralogenetic particle unloading) electrogeochemical ideal model was established for the study area, which takes into account moderate rainfall, high altitude, low air pressure, well-developed vegetation and roots, and an Upper Triassic Nieru Formation carbonaceous sandy slate as overburden. | Panfeng Liu Xianrong Luo Meilan Wen Jiali Zhang Wen Gao Fei Ouyang Xuchuan Duan | 2018 | Acta Geochimica2018，37，3： | 1 |
| 6 | Sustainability evaluation for a circular maize-pig system driven by indigenous microbes:a case study in Northeast China显示文摘Sustainable agricultural development is a topic of global concern aiming at satisfying food demand of the growing population while reducing impact on environment.Circular agriculture has become a promising development pattern with the advantages of complementing environmental resources,replacing feedback from outside system,and processing waste of bottom of system,etc.This study combined economic analysis,life cycle assessment and emergy accounting to evaluate sustainability of an integrated maize-pig system(IS)driven by indigenous microbes in Northeast China,compared with separated maize and pig system(SS).IS reduced input of concentrate feed,coal,vaccines,disinfectants,fertilizer and labor by 14.35%,100%,46.11%,100%,60.1%and 60.8%driven by indigenous microbes.Economic analysis results showed that IS has 82.88%higher profit than that of SS.The sum of potential environmental impacts of IS was lower than SS for 80.65%according to lifecycle assessment.The emergy results revealed that IS performed better sustainability.Internal feedback emergy for fertilizer and local resources for maize straw increasing of IS significantly improved emergy efficiency.The reduction resulted in nonrenewable resources decreased 33.01%than that of SS,and increased renewable resources by 67.81%,which reduced environmental load ratio of IS by 60.08%of IS.Meanwhile,these factors were the primary factors generating higher sustainability of IS.Overall,the integrated maize-pig system driven by indigenous microbes in this study can effectively alleviate the problems caused by agricultural waste and promote sustainable agricultural development. | Yinan Xu Panfeng Li Youhui Gao Yueming Li Shijie Li Yunfeng Li Peng Sui Xiaofen Wang Wangsheng Gao Yuanquan Chen | 2022 | Ecosystem Health and Sustainability2022，8，1： | 0 |
