Introduction

Interpretation of GB/T 43646—2024 Design Requirements for Terrestrial Wildlife Corridors

Dimensions of the Standard Framework	GB/T 43646—2024 Requirements	Comparative Analysis
Design Principles	Scientificity, Targetedness, Feasibility, Coordination	The "coordination" principle has been added, emphasizing the connection between corridors and regional development plans
Survey Scope	1~3 km (habitat corridors), Appendix B is extended to 300~3000 m (channels)	The survey scope is more detailed and dynamically adjusted according to different ecosystem types and engineering categories
Design parameters	Target animal groups, habitat suitability, and resistance coefficient calculation	Introduce the resistance coefficient model (E.1) to enhance scientificity and operability

Implementation suggestions and practical application cases

Case background: A highway is planned to pass through an important wildlife habitat, and a terrestrial wildlife corridor needs to be set up.

Specific measures:

• Carry out detailed investigation: including habitat suitability assessment, human disturbance intensity analysis, and target animal activity route identification (classified using Tables 1-4)
• Corridor functional zoning: The main corridor is the core area, the auxiliary corridor is the buffer zone, and refer to Figure 1 for functional zoning
• Channel site selection and design: Determine the proposed location according to Tables 5 and 6, give priority to the use of existing bridges and culverts, and add guiding facilities (as shown in Figures 3-4)
• Habitat creation and maintenance: Combined with the habits of target animals, plant local vegetation on the upper span bridge deck, set up water replenishment points and anti-predator devices

Standard formulation background and technology evolution analysis

Background:With the rapid development of transportation infrastructure construction, the problem of wildlife habitat fragmentation is becoming increasingly serious. In order to reduce the impact of human activities on terrestrial wildlife and protect biodiversity, my country has gradually established a standardization system in the field of ecological corridor design.

Technological evolution:

• Transformation from single channel construction to comprehensive corridor system
• Introduction of multidisciplinary cross-disciplinary methods of ecology and engineering
• Scientific decision-making based on field investigation and simulation experiments
