### Calculation Results and Analysis of Carbon Footprint Pressure Index
#### 3.2.2 Spatial Distribution Characteristics of the Carbon Footprint Pressure Index  
When examining different counties and districts specifically, in 2010, the Yanshan-Taihang Mountain area within Hebei Province manifested a distinct pattern of regional differentiation. At that time, the carbon balance regions were primarily concentrated in several counties and districts, including Laiyuan County, Fuping County, Fengning Manchu Autonomous County, Chengde County, Longhua County, and Kuancheng Manchu Autonomous County. However, these regions represented only 27.27% of the total number of counties and districts within the entire study area. The reason these areas were able to achieve carbon balance lies in their unique natural conditions and robust ecological foundations. Generally, they exhibited relatively high vegetation coverage rates, which contributed to the development of healthy and stable ecosystems. In these ecosystems, plants efficiently absorbed carbon dioxide from the atmosphere through photosynthesis, converting it into organic matter for storage. Additionally, during the material circulation process within the ecosystem, carbon elements were circulated and reused effectively, maintaining a state of carbon balance and keeping land use carbon emissions in these regions at a relatively low level. In stark contrast, the regions with relatively high carbon cycle pressures were mainly distributed across Wangdu County, Quyang County, Kangbao County, Zhangbei County, Shunping County, Guyuan County, and Wanquan District, among others. These areas were in a phase of rapid economic development, characterized by frequent industrial activities and the acceleration of urban construction, which led to a continuous upward trend in carbon emissions and left them facing relatively substantial environmental pressures. In the process of promoting urbanization and developing industries in Wangdu County, the urban construction land continued to expand, while energy consumption in industrial production kept rising. However, the corresponding ecological greening construction failed to keep pace in a timely manner. As a result, carbon emissions far surpassed the carbon sink capacity of the regional ecological system, and the carbon cycle pressure was mounting on a daily basis. In Quyang County, when the ceramic industry was striving for production output and economic benefits, it overlooked the impact on the environment. The massive energy consumption and exhaust emissions during the production process caused the carbon footprint pressure in the region to remain persistently high. Similarly, in Kangbao County, the development of processing and manufacturing industries faced challenges in controlling carbon emissions due to a lack of comprehensive environmental protection facilities and advanced energy-saving and emission reduction technologies. Consequently, relatively large carbon cycle pressures and environmental risk ensued. During this period, the disparities in the levels of land use carbon emission risk among different regions were quite pronounced. By 2015, significant changes had taken place. Initially classified within the carbon balance area, Fuping County and Laiyuan County gradually transitioned to the carbon imbalance area due to the demands of economic development and changes in land use patterns. This shift resulted in a substantial increase in the proportion of counties and districts in an imbalanced state, reaching as high as 81.82%. Consequently, the majority of counties and districts faced considerable pressures on their carbon cycles and heightened environmental risk. To accelerate its economic development pace, Fuping County actively engaged in investment promotion activities and introduced industrial projects. During the construction and operation of these projects, ecological land was occupied, and simultaneously, energy consumption witnessed a drastic increase, which ultimately resulted in the disruption of the previously stable carbon balance state.
