Analysis of Human Disturbance Features in Natural Reserves and Empirical Research on Their Restoration: A Case Study of the Huangchulin Nature Reserve in Fujian Province

Nature reserves are important areas delineated to protect natural resources and the ecological environment. They have various functions, such as protecting biodiversity, conserving water sources, purifying atmosphere. However, with rapid development of social economy, human disturbance in is becoming increasingly pronounced, which has seriously damaged initial balance ecosystem reserves. Based on specific local conditions reserve, this study selects four influencing factors that closely related activities, namely, land use, vegetation cover, slope elevation primary evaluation indicators disturbance. With support an analytic hierarchy process GIS technology, conducts a comprehensive analysis Fujian Huangchulin Reserve proposes corresponding restoration measures for different disturbed areas. The results indicate area completely by activities primarily around river basin, accounts 25.30% total area. lightly covers largest area, followed intermediately 37.91% 32.96% respectively. smallest slightly only 3.83% analytical functional zoning China, Shitan Stream selected experimental site restoration. According sectors concept “Mountain, Water, Forest, Field, Lake Grass,” “Four-tiered Protection System” proposed experiment, system restoration, brownfield soil conservation, original protection Natural regeneration active then combined be implemented areas, problems brown pollution, cutoff, erosion been effectively solved, plant coverage increased substantially. In summary, shows taking social, economic into account establishing sound management can work proceed smoothly achieve more environmental benefits.
