Comprehensive Evaluation on the Rehabilitation Landscape in Yangtiangang National Forest Park

Abstract

To comprehensively evaluate the rehabilitation landscape of Yangtiangang National Forest Park, the research selected the PSR model, organically combined the rehabilitative landscape pattern, forest ecosystem environment and social economic development to construct a comprehensive evaluation index system for the rehabilitative landscape of Yangtiangang National Forest Park, and used the analytic hierarchy process, entropy method and comprehensive index method to measure the rehabilitation landscape quality of Yangtiangang National Forest Park. The results showed that the comprehensive index of rehabilitation landscape of Yangtiangang National Forest Park in 2006, 2011, 2016 and 2020 was 0. 524 9, 0. 491 5, 0. 482 4 and 0. 621 5 respectively, and the comprehensive level of rehabilitation landscape had achieved from “general” in 2006, 2011 and 2016 to 2020 “good” transition of the year. In the three subsystems of pressure, status quo and reaction, the weights of each index from large to small were the status quo layer (0. 489 9), the pressure layer (0. 291 2) and the reaction layer (0. 218 9). In the comprehensive evaluation index system of the rehabilitation landscape of Yangtiangang National Forest Park, landscape passenger flow, regional water quality compliance, ecological conservation function and regional environmental protection investment were the most critical factors affecting the comprehensive level of the forest park's rehabilitation landscape.
