[Spatial heterogeneity of land use intensity]

Area of Science:

• Environmental Science
• Geography
• Urban Planning

Background:

• Land cover change dynamics are significantly influenced by the spatial heterogeneity of human disturbance.
• Jinjiang City, Fujian Province, is a region experiencing intense land use change and human disturbance.
• Understanding the directional structure of human disturbance is crucial for effective land management.

Purpose of the Study:

• To analyze the spatial heterogeneity of land use intensity and human disturbance in Jinjiang City from 1989 to 2001.
• To identify the directional characteristics and structural patterns of human disturbance.
• To investigate the influence of traffic lines and administrative centers on human disturbance patterns.

Main Methods:

• Systematic grid sampling was employed to collect data across the study area.
• Geostatistical methods were applied to analyze spatial patterns and heterogeneity.
• Spatial analysis techniques were used to map and quantify human disturbance.

Main Results:

• Significant spatial heterogeneity in human disturbance was observed, with a distinct NE-SW directional structure.
• Human disturbance increased across the entire study area during the period.
• Administrative centers acted as growth poles, contributing to a pole-axis structure of human disturbance, influenced by traffic lines.

Conclusions:

• Human disturbance in Jinjiang City exhibits a clear pole-axis structure, driven by the interplay of traffic infrastructure and administrative centers.
• The findings provide insights into the spatial dynamics of human disturbance, essential for understanding land use change.
• Effective land use planning should consider these identified directional patterns and growth poles for sustainable development.
