Analysis on sensitivity and landscape ecological spatial structure of site resources

Area of Science:

• Landscape Ecology
• Environmental Science
• Spatial Planning

Background:

• Site resources require standardized evaluation for effective land planning and management.
• Landscape ecology offers robust theories and approaches for assessing ecological sensitivity.
• Existing methods may lack qualitative-quantitative integration for small to medium-scale analyses.

Purpose of the Study:

• To establish indicators and standards for landscape ecological sensitivity analysis of site resources.
• To develop a qualitative-quantitative evaluation method for land planning and management.
• To assess the landscape ecological sensitivity of Yantian District, Shenzhen.

Main Methods:

• Utilized landscape ecology theories and approaches.
• Employed landscape diversity index (H), evenness (E), natural degree (N), and contrast degree (C).
• Analyzed spatial structure and landscape heterogeneity of site resources.

Main Results:

• Identified high landscape ecological sensitivity in Wutong Mountain, Shenzhen.
• Classified Sanzhoutian and Shangping Reservoirs as medium sensitivity and high ecological sensitivity areas.
• Determined Dameisha and Xiaomeisha as medium sensitivity areas due to declining natural environments; Shatoujiao and Yantian Pier as low sensitivity areas, significantly impacted by urban development.

Conclusions:

• The developed method provides a reliable qualitative-quantitative evaluation for landscape ecological sensitivity.
• Specific areas within Yantian District exhibit distinct sensitivity levels, necessitating tailored management strategies.
• Recommendations for planning, protection goals, and development intensity were proposed for each identified zone.
