The Spiritual Research of Yanshan-Taihang Mountain Poverty Alleviation Cadres under the Background of New Era

Eliminating poverty, improving people's livelihood, and gradually achieving common prosperity are the essential requirements of socialism. After more than 40 years of reform and opening up policy, China has embarked on a path of poverty alleviation with Chinese characteristics. In precise poverty alleviation, cadres in villages have become an important force to tackle the problem, and contact channels. Through studying the actual situation of the implementation of the basic strategy of the Party Central Committee’s precise poverty alleviation in the concentrated and contiguous areas of Yanshan-Taihang Mountain, it is truly reflected in the successful examples of grassroots forces winning the battle against poverty under the strong leadership of party committees and governments at all levels. Finally, the research demonstrates the new era style of the vast number of poverty alleviation cadres stationed in the village taking up the role, dedicating to the grassroots, and making sacrifices on the battlefield of poverty alleviation.

The Chloroplast Genomes Comparative Analysis of Taihangia Rupestris and Taihangia Rupestris Var. Ciliate, Two Endangered and Endemic Cliff Plants in Taihang Mountain of China

The Taihangia is a native endangered cliff species that grows in the Taihang Mountains in China. The cp genomes with a whole length of 155,558 bp and 155,479 bp for Taihangia rupestris and Taihangia rupestris var. rupestris. They have 131 genes in total, covering 79 protein-coding genes, 29 tRNA, and 4 rRNA. Analyses of codon usage, RNA-editing sites, repeat sequences, and comparison of cp genomes showed a high degree of conservation. Phylogenetic analysis indicated that the Taihangia are closed to the Geum. Taihangia genus was inferred to have originated at 0.2057 Mya, and Geum rupestre was inferred to have originated at 1.4431 Mya. Overall, the gene contents, gene arrangements, the types, and frequency of codon usage, repeat sequences, and SSRs are similar and highly conserved in the species of T. rupestris and T. rupestris var. ciliate. It is found that based on bioprospecting, T. rupestris and T. rupestris var. rupestris are potential medicinal resources. This study provides a scientific basis for the conservation and sustainable use of endangered medicinal resources..

Response of Soil Respiration and Its Components to Precipitation Exclusion in Vitex negundo Var. Heterophylla Shrubland of the Middle Taihang Mountain in North China

Assessing the response of soil heterotrophic and autotrophic respiration to climate change is critical for forecasting terrestrial carbon cycle behavior in the future. In the present study, we conducted a drought experiment in Vitexnegundo var. heterophylla shrub ecosystem of the Middle Taihang Mountain. Three precipitation manipulation treatments (natural conditions/ambient precipitation (CK), reduced precipitation by 30% (PE30), and reduced precipitation by 60% (PE60)) were used to study the impact of different levels of precipitation exclusion on total soil respiration (Rs) and its heterotrophic (Rh) and autotrophic (Ra) components. Our results showed that the rates of Rs and its components were significantly decreased under the precipitation exclusion treatments. The proportion of Rh in Rs reduced from 72.6% for CK to 71.9% under PE60. The annual cumulative C fluxes of Rs decreased by 47.8 g C m−2 in PE30 and 106.0 g C m−2 in PE60, respectively. An exponential relationship was observed between the rate of each soil respiration component and soil temperature in all treatments ( p < 0.01). Moreover, each soil respiration component rate was better represented by a quadratic model which included soil moisture ( p < 0.01). However, including both of soil temperature and soil moisture did not explain more variation in soil respiration components compared than the regression model with soil moisture only. In addition, excluding precipitation increased the temperature sensitivity (Q10 values) of Rs and its Ra and Rh components compared to the control. Collectively, our findings suggest that increased drought will inhibit the release of carbon from the soil to the atmosphere, and will likely decrease the contribution of Rh to Rs in this semiarid shrubland ecosystem.

Hydrochemical Characteristics and Formation Mechanism of Strontium-Rich Groundwater in Shijiazhuang, North China Plain

Strontium is a kind of trace element. Groundwater containing strontium is called mineral water when its content reaches a level that is beneficial for human physiology. Some groundwater resources in Shijiazhuang are rich in strontium. In this study, groundwater samples collected from 103 sites were studied for the hydrochemical characteristics of strontium and its formation mechanism in the groundwater system in Shijiazhuang City. The methods of source provenance analysis, factor correlation analysis, and runoff condition analysis were carried out in the study. The results showed that the content of strontium in eastern Shijiazhuang is higher than 0.229 mg/L, with a maximum content of 1.942 mg/L. The source of strontium is the dissolution of strontium-containing minerals in carbonate rock, sheet hemp rock, clastic rock, and granite in the Taihang Mountain area of the Hutuo River Basin. Strontium is positively correlated with total dissolved solids, bicarbonate, calcium magnesium, and free carbon dioxide. The erosion ability of groundwater strengthens the dissolution of strontium, and the geochemical action is mainly due to the dissolution. The enrichment and distribution of strontium are related to the conditions of groundwater runoff. Areas with good runoff conditions and strong mining are low in strontium, while areas with poor runoff conditions have high strontium content.

The Taihang Mountain Region of North China is Experiencing A Significant Warming Trend

The Earth’s climate has warmed by approximately 0.6 °C over the last century, but temperature change in the Taihang Mountain region—an important transition zone in North China which functions as an ecological barrier for Beijing, Tianjin, and other big cities—is still unknown. In this study, we analyze the spatial and temporal trends in the average annual and seasonal surface air temperature in the Taihang Mountain region from 1968 to 2017. The effect of elevation, longitude, latitude, percent forestland, percent farmland, and gross domestic product (GDP) on temperature was also determined. Our results show that the Taihang Mountain has warmed by 0.3 °C/decade over the past five decades. Partitioned seasonally, average warming was 0.38, 0.14, 0.21, and 0.47 °C/decade in spring, summer, fall, and winter, respectively. Elevation and latitude were significantly negatively correlated with temperature but had no correlation with the temporal warming trend (i.e., the Z value from a Mann–Kendall test). The Z value was significantly negatively correlated with percent forestland and positively correlated with GDP, indicating that economic development has induced warming, but afforestation may reduce the rate of warming increase. Together, our results provide important insights into the rates and drivers of climate change within mountainous regions.
