Evolution Characteristics of Ecological Resilience in Typical Areas along the Phnom Penh-Sihanoukville Expressway
Different ecological environments in the highway pathway area respond differently to the construction,and the increasing intensity of highway construction is becoming more and more prominent in terms of ecosystem disturbance.This study focuses on a typical area within a 1km range of the Phnom Penh-Sihanoukville Expressway and uses remote sensing and geographic information systems technology to analyze the ecological resilience evolution characteristics of typical areas along the expressway from 2017 to 2021.The study selects ecological restoration and resistance indicators and uses a comparative analysis method to assess ecological changes.The study results reveal that the area of forest land in the Poundishi and the Koh Kong Provinces decreased by 24%from 2017 to 2021,while the area of unused land doubled.The center of gravity of each land use type shifted towards the direction of highway construction,and overall,land use types showed a trend of decreasing natural attributes and increasing human attributes.During the study period,the ecological resilience of the two research areas exhibited a downward trend and an"East big,West small"evolutionary trend.
