To evaluate differences among 19 different ploidy hybrid poplar clones grown in northeast China, 21 traits related to growth traits and photosynthetic characteristics were detected and analyzed. Abundant phenotypic variations exist among and within populations, and these variations are the basis of forest tree genetic improvements. In this research, variance analysis showed that the traits except the net photosynthesis rate among the different ploidies and all the other traits exhibited significant differences among the ploidies or clones (p < 0.01). Estimation of phenotypic coefficients of variation, genotypic coefficients of variation, and repeatability is important for selecting superior materials. The larger the value, the greater the potential for material selection improvement. The repeatability of the different traits ranged from 0.88 to 0.99. The phenotypic and genotypic coefficients of variation of all the investigated traits ranged from 6.88% to 57.40% and from 4.85% to 42.89%, respectively. Correlation analysis showed that there were significant positive correlations between tree height, diameter, and volume. Transpiration rate, intercellular carbon dioxide concentration, and stomatal conductance were significantly positively correlated with each other but negatively correlated with instantaneous water use efficiency. Growth traits were weakly correlated with photosynthetic indexes. The rank correlation coefficient showed that most of the growth indicators reached a significant correlation level among different years (0.40–0.98), except 1-year-old tree height with 4-year-old tree height and 1-year-old ground diameter with 3-year-old tree height, which indicated the potential possibility for early selection of elite clones. Principal analysis results showed that the contribution rate of the first principal component was 46.606%, and 2-year-old tree height, 2-year-old ground diameter, 3-year-old tree height, 3-year-old ground diameter, 3-year-old diameter at breast height, 3-year-old volume, 4-year-old tree height, 4-year-old ground diameter, 4-year-old diameter at breast height, and 4-year-old volume showed higher vector values than other traits. With the method of multiple-trait comprehensive evaluation to evaluate clones, SX3.1, SY3.1, and XY4.2 were selected as elite clones, and the genetic gains of height, basal diameter, diameter at breast height, and volume of selected clones ranged from 12.85% to 64.87% in the fourth growth year. The results showed fundamental information for selecting superior poplar clones, which might provide new materials for the regeneration and improvement of forests in Northeast China.

The CO2 emissions of highway transportation industry are huge. In order to study factors affecting carbon emissions of highway operation period, selected five primary route design indicators to analyze. The five indicators were Speed, Gradient, Radius of Curvature, IRI, Traffic Volume and Green Belt. Combined the existing Carbon Accounting Model and the Carbon Accounting Software of Highway Operation Period[4], which could calculate the equivalent carbon emissions. By using Gray relational analysis method, calculated the relational degrees between route design indicators and carbon emissions of highway operation period. At last, found that the most important factor affecting carbon emissions of highway operation period was average daily traffic volume. The research will be helpful to discuss the carbon emissions of highway operation period in a targeted manner.

As an essential part of the highway ecosystem, road plants can absorb much carbon dioxide emitted by operating vehicles. In this study, road plants’ carbon sequestration capacity and carbon neutralization strategy were quantitatively investigated. Firstly, the structure of the asphalt pavement of the expressway was formulated, and the carbon emissions of asphalt pavement at each stage were calculated and analyzed through construction site data monitoring and reference to the life cycle assessment database. Secondly, combined with the theory of carbon sequestration and oxygen release, quantitative analysis was carried out on the photosynthesis of typical green plants, and the carbon sequestration amount of different plant combinations was calculated. Finally, based on the carbon neutralization goal, the time required to complete the carbon emission neutralization in the construction period was proposed. The results show that different plant types have different carbon sequestration and oxygen release capacity for carbon emissions in the road system, and a reasonable combination of plants can greatly reduce the number of years required to complete carbon emissions during the construction period of unit functional roads. This study has great theoretical significance and practical value for reducing carbon emissions and achieving sustainable development.
