Dushan county, Guizhou province, is located in the southernmost tip of Guizhou province. It belongs to the temperate climate of the subtropical region and is one of the centers of the karst east Asia area. The total area of the county is 242220 hectares, of which 169142 hectares are rocky desertifi cation or endangered desertification state. At present, the problem of rocky desertification has seriously affected the ecological environment of the county, which is one of the important factors that restrict the local social living standard and economic development. Therefore, it is of great significance to promote the social and economic development of the county by investigating and analyzing the spatial differentiation rules, present situation and harm of rocky desertification in Dushan county.

The effects of Zn2+ stress on seed germination, seedling growth and chlorophyll content were studied in order to better understand the effect of heavy metal Zn on the growth and development of green plants. The concentration gradient of Zn2+ was 20, 50,100,150,200,300,500,700mg / L, and deionized water was used as control. The results showed that under the Zn2+ stress condition, the germination index of the rhubarb seeds increased with the increase of Zn2+ concentration. Germination potential, germination rate and germination index were the highest when Zn2+concentration was 100mg / L, the conductivity was the lowest at zinc concentration of 100mg / L, the root length, stem length and chlorophyll content of Zn2+ gradually reduced. The results showed that the amount of Zn2+ could promote seed germination, but the root length, bud length and chlorophyll content of seedlings could be affected by different degrees. The zinc fertilizer should be used in the production.

In addition to create a beautiful and comfortable environment for human beings, it is more important to create an ecological environment suitable for human beings. Plant landscaping is no longer just the use of plants to create visual effects of the landscape, it also contains the ecological landscape, cultural landscape and even deeper meaning. In this article, the concept of ecological garden the benefits produced and the related content of plant landscaping are analyzed, and the situation of plant disposition and existing problems in Shenyang area are analyzed concretely.

Purpose: This paper articulates a model that maximizes the use of e-HRM to achieve sustainable competitive advantage. It examines the indirect effects of e-HRM use on sustainable competitive advantage, through job satisfaction, employee performance, and perceived organizational politics. Design/methodology/approach: A survey approach was used to collect data from 30 organizations. A purposive sampling technique was used to select the study sample. The SPSS PROCESS Macro for running mediation analysis was used to analyze data. Findings: The findings show the indirect effect of e-HRM on sustainable competitive advantage through job satisfaction, employee performance, and perceived organizational politics. Job satisfaction has the biggest effect on achieving strategic outcomes. For organizational excellence, e-HRM use should complement other HRM practices. Practical implications: Management should pay attention to employee outcomes during the implementation of e-HRM. This study broadens the scope of the interaction between e-HRM use and sustainable competitive advantage. This study was conducted in a developing economy and demonstrated that the effects of e-HRM use on sustainable competitive advantage are not limited to developed economies. Originality/value: This study is one of the pioneering efforts to develop a model that maximizes organizational outcomes in developing countries. In addition, this study contributes to the understanding of intervening variables necessary to enhance information technology’s potential within the HR function.

Several studies have discussed the benefits of blockchain in human resources management (HRM) policies to support the efficiency of HRM routine practices in organizations. The discussion ranges from selection and recruitment to employee separation. With the growing interest in digital application usage, research focused on utilization and effective measurement is needed. However, the existing literature review on blockchain-based HRM practices linked to cost efficiency still needs to be improved. Hence, this study aims to review current studies on blockchain human resources management systematically. This study investigates the trends in blockchain application usage in terms of practices, methodologies, and settings. This study used a literature survey and Publish or Perish software with Google Scholar and Scopus as the databases. 123 articles published in 19 journals from 2010 to 2022 were selected. This study used systematic data to reveal trends in HRM practices and qualitative inductive analysis to define relevant themes within the topic. The results show that blockchain applications for efficiency are used mainly in the recruitment and selection process, ranging from personal data verification to the quality of decision-making in skill development and maintenance. Five HRM practices have been discussed, indicating potential explorative and exploitative future research to improve the effectiveness of using blockchain in HRM practices.

The article discusses the actual problems of practical training in the tourism and hospitality industries in Russia and identifies the main problems of training specialists at Russian specialized universities. The main focus is on building partnerships between universities and employer organizations in order to train highly qualified specialists. Purpose: The research is aimed at creating an effective model of practical training based on the interaction of the university with employer organizations within the framework of the training of specialists in the tourism and hospitality industries. Design/Methodology/Approach: The work is based on scientific publications devoted to evaluating the effectiveness of the existing system of personnel training for the tourism and hospitality industries, studying its features, building models of vocational education, and using practice-oriented programs in the training of specialists. To study the problems of practical training of personnel for tourism and hospitality, systematic and structural approaches were used as a methodological basis, as well as methods of analysis and synthesis, the study of models of cooperation between universities and employers, and methods of monitoring and evaluating the quality of training specialists. To obtain empirical data, an analysis of the needs of the labor market for specialists in the hospitality industry was carried out, as was the study of models of cooperation between universities and employers. Results: In the course of the work, the author has formed a model of practical training for specialists in the tourism and hospitality industries, including the purpose and objectives, process requirements, organization conditions, and requirements for the results of the process. The innovative nature of the proposals lies in the development of new models of practical training based on gamification technology. The direction of further research may include the development of a methodology for the organization of the university’s interaction with employer organizations in the framework of practical training. Conclusion: The results of the study can be used by professional educational organizations to organize the process of practical training of students, which will effectively solve the problem of training personnel for tourism and hospitality. The social consequences of organizing the process of practical training for students will include increasing the competitiveness of graduates in the labor market, improving the quality of tourist and hotel services, introducing innovations into the tourism and hospitality industries, and developing startups.
