Abstract: A ridge with an ecological isolation zone and a construction method thereof. The method includes: (1) spreading a geotextile on the bottom of a trimmed ridge; (2) stacking reinforced soil on the geotextile; (3) folding the geotextile from the end away from the ridge upwards and inwards to wrap the reinforced soil; (4) continuing to stack the reinforced soil on the folded end of the geotextile, and then trimming to form a first layer of reinforced soil ridge-protection structure; (5) repeating steps (1) to (4) to further construct multiple layers of reinforced soil ridge-protection structure. The present invention no longer uses an ecological bag to pack a soil mixture, and thus can reduce the cost of construction. Moreover, owing to the separation of geotextile and the consolidation of reinforced soil between two adjacent layers of reinforced soil ridge-protection structure, a more stable ridge structure is formed.
