Tourism Economy

With the implementation of the Belt and Road Initiative and the national strategy of “Ecological Protection and High-Quality Development in the Yellow River Basin”, the tourism development of the Yellow River basin of China is facing important opportunity. However, the spatial differences of tourism economy and the unbalanced development of interprovincial resources has become a threat for the sustainable development of the basin. By using the statistical data from 2003 to 2018, this paper aims to identify the numerical feature and spatial patterns of tourism development in the Yellow River Basin from the aspects of tourist volume (domestic tourists and inbound tourists) and tourism income (income from domestic tourism and inbound tourism) at provincial and prefectural scales. Analysis of spatial autocorrelation reveals significant clusters and outliers of tourist volume and tourism income at prefectural scale. Location condition, terrain condition, culture resources, regional policies, the interregional relationship and tourism infrastructure were the main factors influencing the spatial differences of tourism development in the Yellow River Basin. The study could offer useful information for the regional tourism management in the Yellow River Basin.

The Yellow River Basin

The Yellow River Basin is ecologically fragile, the relationship between water and sand is unbalanced and water resources are scarce. This paper takes the urban agglomerations in the Yellow River Basin as the research object, based on the guidelines for the coordinated promotion of ecological protection and high-quality development in the basin, and uses the entropy weight method and the coefficient of variation method as the means to establish a quantitative evaluation system for coordinated development. The degree of synergy is between ecological protection and high-quality development of the urban agglomerations from the time dimension and the space dimension, and we give the optimization directions. The results show that the degree of synergy among urban agglomerations in the river basin is steadily increasing, but there are significant spatial differences in the degree of coordination of ecological protection and high-quality development of the urban agglomerations and the development index of its subsystems. The degree of synergy generally presents a cascade distribution pattern that gradually decreases from east to west and from downstream to upstream. The ecological destruction, economic fluctuations and water waste of the river basin urban agglomeration are the main factors hindering the improvement of synergy.

Number Of Cycles

As a national development plan, ecological protection of the Yellow River Basin has attracted extensive social attention in recent years. Considering the influence of acid rain on the engineering characteristics of loess in this area, we investigated changes in the physical and mechanical characteristics of remolded loess under the combined action of acid rain and dry-wet cycles by means of triaxial tests, nuclear magnetic resonance spectroscopy, and scanning electron microscopy. The results are as follows: in the acidic environment, the stress-strain relationship of remolded loess undergoes stress hardening after dry-wet cycling. The cohesion and internal friction angle of remolded loess are negatively correlated with the number of cycles. From the multiscale analysis of the dry-wet cycle process under acid rain condition, the T2 spectrum of the test soil has three peaks at the micropore level. With the increasing number of cycles, the spectral area increases gradually, and the sample transitions from small pores to large- and medium-size pores. At the microscopic level, the clay mineral particles among soil particles decrease in size, the contact mode between soil particles develops from stable to unstable, the particles are gradually rounded, and the fractal dimension decreases. Chemical erosion and physical erosion are special features of this experiment. Physical erosion causes particle erosion and pore growth, while chemical erosion includes reactions by feldspar. Together, physical and chemical reactions aggravate the soil deterioration process. These research results have laid a good experimental foundation for the ecological protection of the Yellow River Basin.

The Yellow River Basin

<p>The Yellow River Basin is rich in land, energy, and mineral resources, which is an important energy base and major food producing area in China. However, water shortages have become a key factor restricting the development of the basin. With the economic and social development and population growth, resources demand of water, food and energy in the river basin has been further increased under the drive of national energy security and food security strategies. The conflict between resource supply and demand has become more prominent. This paper selected 9 provinces of the Yellow River Basin as the study area, and collected 16-year time series data, and quantitatively describes the temporal and spatial coordinated changes of water, energy, and food through methods such as MK test and synergetic evaluation system. The results show that in the nine provinces of the Yellow River Basin, the water supply has increased slightly, and energy and food production have increased significantly. The spatial differences of water supply and food production have little change and are relatively stable, while the change of spatial differences in energy production are more obvious with a downward trend, indicating that regionalization of energy production areas is becoming more and more obvious. According to the synergetic evaluation system, the coefficients of synergy for all of the nine provinces are gradually increasing. The evaluation coefficient of Henan is relatively high, indicating that Henan has a positive synergy of water, energy, and food resources. And the Ningxia province has the lowest evaluation coefficient. According to the results, the water energy and food system reconfiguration should be carried out for key provinces, and the allocation of water energy and food resources should be optimized to maximize the utilization of the three resources and achieve sustainable use.First of all, adjusting the energy structure among the provinces with poor synergy. For example, raw coal is still the core resource of energy consumption which is water-intensive. Reduce the investment in coal chemical industry and other high water-consumed energy industry to have a better synergy coefficient. Also, develop more clean energy, for example, hydro-power, nuclear power and wind power. Nowadays, the environment-friendly and resource-saving clean energy portion is less than 10% of the total energy consumption. The waste resources can be reuse to provide green energy. Last, high-end production technology in energy production is important to guarantee the water and energy safety. </p>

As a major national strategy, ecological protection and high-quality development of the Yellow River Basin aims to promote high-quality development in the areas of economy, ecology, society, people’s livelihood, and tourism. Taking 9 cities in the Shandong section of the Yellow River Basin as the main research area, the entropy Topsis method is used to analyze and evaluate the tourism development potential. The evaluation index system is constructed from the four subsystems of tourism economic potential, tourism service potential, tourism protection potential, and tourism environmental potential. The results of the study found that the comprehensive score of tourism development potential of the study area is between 0.2734 and 0.7054, with Ji’nan having the highest comprehensive score. At the same time, there is an imbalance in the development level of various subsystems within the region. On this basis, high-quality development countermeasures are proposed for the tourism development.

Land resources are the basis of human survival and development. Land use benefit is the embodiment of land input-output ability. As an important economic zone and ecological barrier in China, it is important to calculate the land productivity in the Yellow River Basin. Using the center of gravity model and other methods, this study evaluated the land use benefit of the Yellow River Basin from 1995 to 2018 based on the selected indicators of geographic grid-scale and analyzed the regional disparity. The results revealed that the comprehensive benefits, economic benefits, and social benefits of land use were on the rise, but the ecological benefits changed in volatility. Land circulation had a great impact on the change of land use benefits. So reasonable land transfer policy should be particularly significant for land use in the Yellow River Basin. In addition, there were obvious spatial differences and agglomeration effects in land use benefit. The high values of benefits were concentrated in urban groups, which showed that areas with better economic and social development had better land use benefits. To narrow land use benefits’ spatial differences between regions, the less developed areas deserve more preferential policies to improve their economic and social levels. Besides, ecological benefits are generally not high. Thus, the land policy in the Yellow River Basin should take ecological priority as the basic principle while considering economic factors.
