Ecological Restoration Strategy of Abandoned Mines Based on Giant Panda Distribution Statistics: A Case Study of the Giant Panda National Park (Ya'an Area, Sichuan)

Abstract

Taking the Giant Panda National Park (Ya'an Area, Sichuan) as the research area, based on the current status of giant panda distribution points and comprehensive consideration of the impact of terrain, natural resources, climate, atmosphere, vegetation, and bamboo on giant panda distribution, a comprehensive evaluation index system for the living environment of giant pandas is constructed for evaluation, combined with on-site investigations, and the impact of abandoned mines on the distribution of giant pandas is judged, and finally an ecological restoration strategy for abandoned mines is obtained. The results are as follows: (1) priority should be given to restoration of abandoned mines in areas where the elevation, aspect, precipitation, and temperature are suitable for the survival of giant pandas. (2) During the restoration of the mine, a variety of bamboos, firs and shrubs with different flowering cycles are selected for mixed planting in the same area, within a controllable number of years, form a Closed evergreen needle-leaved forest (fc >0.4), and meet the NDVImax within the range of 0.8-1.0. (3) The pollution of the atmospheric environment by construction dust, vehicle exhaust, and asbestos mines will be prevented through manual intervention. (4) The slope should be trimmed within the range of 23-48° as much as possible, and the water source for giant pandas should be appropriately increased. This study provides an important basis for the restoration of abandoned mines in the Giant Panda National Park (Ya'an area, Sichuan), and will also provide a reference for the restoration of abandoned mines in other areas and the entire Giant Panda National Park.
