[Construction of Ecological Security Pattern in Hangzhou Based on MSPA and InVEST Model].

， accounting for 22% of the city's total area. The distribution of these sources was reasonable， especially with strong connectivity in the southwest， facilitating species migration. ② Fifteen ecological corridors， totaling 333.4 km in length， were extracted using the LM tool. These corridors connected different ecological sources， with a set width of 50 meters to ensure the highest forestland proportion， fostering migration and effective ecological functioning. ③ Twenty-four critical areas needing restoration were identified， including eleven core protection zones， three diagnostic enhancement zones， eight key restoration zones， and two source connection areas. This study provides key area identification for ecological corridor construction in Hangzhou and offers scientific guidance for enhancing and restoring critical zones.
