Research on Ecological Sensitivity in Northwestern Sichuan
摘要
Taking northwestern Sichuan as the research object, ecological sensitivity evaluation is conducted through six factors including elevation, slope, land use, vegetation coverage (NDVI), river buffer, and geological disaster buffer. The results show that the area in the northwest of Sichuan is 6417.09 km2, accounting for 2.76%; the low-sensitive area is 8705.54 km2, accounting for 3.74%; it was 70,673.30 km2, accounting for 30.36%; the area of extremely high-sensitive areas was 646.75 km2, accounting for 0.28%; more than 90% of the research zone are in the middle and high sensitivity.
