摘要：The Pailugou watershed of the Qilian Mountains in the arid region of northeast China was selected for research to analyze the species, height, and biomass in typical mountain grassland with an altitude of 2,700–3,000 m and measure soil moisture, so as to explore the seasonal characteristics of grassland biomass as altitude increases and the relationship between grassland biomass and soil moisture. The results showed that:(1) with a mean value of 135.36 g/m^2, grassland aboveground biomass showed a unimodal distribution from rise to decline as altitude increased, and reached its maximum of 176.79 ± 28.37 g/m^2 at an altitude of 2,900 m; with a mean value of 946.13 g/m^2, grassland underground biomass showed an uptrend as altitude increased, and reached its maximum of 1,301.19 ± 68.24 g/m^2 at an altitude of 3,000 m;(2) the difference between aboveground biomass and underground biomass in the grassland at different altitudes was significant;(3) values of root shoot ratio of the arid mountain grassland varied between 4.14–11.95;(4) values of soil moisture content of the arid mountain grassland varied between 9.23%–31.31%;(5) there was a positive correlation between aboveground biomass and underground biomass and the mean soil moisture content(p < 0.05), with a correlation coefficient of 0.778 4 and 0.784 3 respectively, soil layers with different moisture content made different contributions to grassland biomass, and moisture content in the soil layer where over-60-cm root systems were located was of significance to grassland biomass.

摘要：传统的生产管理往往面临着较为严重的“黑盒”问题,即不能及时掌握现场的各类信息,导致现场实际状态与预期计划脱节,并进一步导致效率降低、质量下降。针对这一问题,主要研究了面向数字孪生的监控系统实现关键技术,在虚拟空间中建立生产线的三维模型,通过现场数据的采集,实现数据与模型的关联映射,并通过各类状态及绩效看板,打造虚拟领导驾驶舱,从而解决生产现场的透明化,促进生产效率、质量的提高。
