It is particularly important for college students to form a good career development plan during the critical period of life transition in college. Career planning level is one of the important abilities for the comprehensive development of college students. To improve the career planning level of college students will help them have a better understanding of the future and achieve better development. In this thesis, the university students as an example, using the way of questionnaire survey to collect data, and through descriptive statistics, analysis of variance, correlation analysis, regression analysis and other statistical methods to process and analyze the data, in order to understand the basic situation of undergraduate career planning in Shandong Jianzhu University. Through the analysis and research of the data, the thesis finds out some problems in the career planning of college students and some factors that affect the career planning. Finally, it puts forward three suggestions: college students should set up the correct view of career choice, parents should actively communicate with their children and colleges should vigorously carry out career counseling courses.展开更多

Consequently, planning suitable travel routes and selecting appropriate cities for these visitors has become a matter of utmost importance. This study aims to scientifically assess the impact of various cities and attractions on tourism choices by analyzing multidimensional factors such as attraction ratings, transportation convenience, and culinary offerings. Through the establishment of statistical analysis models and optimization models, we have conducted comprehensive evaluations. In response to the specific needs of foreign tourists, we have paid particular attention to selecting “cities with the highest number of top-rated attractions” and “the 50 most desirable cities for foreign tourists” based on a comprehensive evaluation of these factors. Additionally, this study has also considered how to design optimal travel routes for tourists, specifically addressing the challenge of maximizing the number of cities visited within a 144-hour time limit while ensuring the best overall travel experience through the use of transportation modes such as high-speed rail. To tackle the specific challenges of travel planning, we have employed methods such as the greedy algorithm and linear weighted comprehensive evaluation algorithm to find optimal solutions that meet both time and cost-effectiveness criteria. Through in-depth analysis and solving of these issues, this study aims to provide high-quality travel experiences for foreign tourists and further promote the development of China's tourism industry.展开更多

This study, taking Guangxi Zhuang Autonomous Region as an example, explores the connection between population-land allometric growth and economic development from the perspective of urban centralization. By introducing fractal geometry theory, we quantify the complexity of urban morphology and analyze the unevenness in various development sectors of the city through the concept of allometric growth. The study employs box-counting dimension methods and multi-radial analysis to calculate local fractal dimensions, and utilizes the entropy weight method to construct an economic agglomeration index to assess the agglomeration effects of urban economies. The research finds that the local fractal dimension of Guilin City ranges between 0 and 1.7 from 2014 to 2022, dividing it into four stages that reflect different levels of urbanization. By constructing a model of the economic agglomeration index and local fractal dimension, a strong positive correlation between the two is revealed, indicating that the optimization of urban structure can promote the concentration of economic activities. Moreover, the allometric growth indices of various cities in Guangxi unveil the unevenness between population growth and land expansion, which holds significant implications for urban policy making and planning. This study provides valuable references for optimizing urban planning and achieving coordinated regional development, contributing to a better understanding of the distribution characteristics of urban economic activities and how optimizing urban structures can promote balanced economic growth.展开更多
