Research on the Tourism Space Structure in Lingui District of Guilin Based on the Development and Utilization of Landscape Resources

The 257 scenic spots in Lingui covered 5 main categories, 14 sub-categories and 26 basic types, in which there were 33 natural scenic spots and 224 humanistic scenic spots, featured by rich resources stock, humanistic landscape resources-based, and significant space agglomeration; the quality levels are 11 high-quality scenic spots that most of them have been developed, 57 good scenic spots and 189 ordinary scenic spots that have big development potential; of the 36 scenic spots developed so far, 7 are natural, and 29 are humanistic(22 of them have been oriented by cultural relic protection sites); from initial scattered-point to intensive scattered-point to point-axis period, they showed stepped and multi-center structure situation. We found that: 1) five levels of growth pole have been formed; 2) The influence mechanism of development on tourism space is: the theme park is the greatest, the natural landscape resources is secondary and the cultural landscape resources is the least, the former-residence -type cultural relics protection sites and traditional villages have a certain influence, and the influence of high-level landscape resources is big in general. Based on the above results, we can build the tourism space structure with “one ring, one core, one sub-core, and three axes”

Groundwater Hydrogeochemical Processes and Potential Threats to Human Health in Fengfeng Coal Mining Area, China

The Fengfeng mining area is in the transition zone between the North China Plain and the Taihang Mountains, and groundwater is the main source of water supply in the district. Under the combined influence of human activities and natural geological conditions, the quality of different types of groundwater varies greatly, posing a potential threat to the safety of drinking water. In this study, hydrogeochemical processes in different types of groundwater were analyzed using multivariate statistical analysis methods with ion–ratio relationships, and a groundwater quality and health risk assessment model was developed. The research findings show that the main chemical components and TDS in the groundwater have obvious spatial distribution characteristics, i.e., the content of deep karst water (DKW) in the west is significantly lower than that of shallow pore water (SPW) in the east, and the hydrochemical type has changed from HCO3–Ca to SO4–Ca. The chemical components of SPW and DKW are mainly derived from silicates and carbonates, accompanied by weathering dissolution of sulphidic minerals, especially SPW. The chemical components of the groundwater was also influenced by the cation exchange reaction and human activities. The quality of the SPW was significantly worse than that of the DKW, and the nitrates in SPW carry a high non-carcinogenic risk, especially to children. The shallow pore water is not suitable for drinking water. This study can provide guidance on the safety of drinking water in the Fengfeng coal mining area and other areas with intensive industrial, mining, and agricultural activities
