Abstract:

This study evaluated and dynamically simulated the forest ecosystem services (FES) within the Luoshan National Nature Reserve (LNNR), Ningxia, China, aiming to provide a scientific basis for local ecological construction and forest management. Focusing on the forest ecosystem of LNNR, we assessed and projected the FES values from 2016 to 2030 based on the Specifications for Assessment of Forest Ecosystem Services in China (LY/T 1721-2008). The results indicate that the total annual FES value of LNNR forests was 2.8934×10⁸ yuan·a-1. The services ranked in descending order of value were: soil conservation>biodiversity protection>water conservation>carbon sequestration and oxygen release>atmospheric environment purification>timber resources. Notably, soil conservation, biodiversity protection, and water conservation collectively accounted for 91.77% of the total value. The aggregate FES value exhibited a consistent annual increase from 2016 to 2030, reaching 4.48×10⁸ yuan by 2030. Over this 15-year projection, the functional values for both arbor forests and shrub forests-encompassing soil conservation, biodiversity protection, water conservation, carbon sequestration and oxygen release, atmospheric environment purification, and timber resources-demonstrated a sustained upward trend. Specifically, shrub forests yielded higher values than arbor forests for soil conservation, biodiversity protection, and water conservation. Conversely, arbor forests provided greater value for carbon sequestration and oxygen release, atmospheric environment purification, and timber resources. In conclusion, the forest ecosystem within LNNR possesses substantial ecological service value locally, which is projected to increase over the next 15 years. Consequently, enhanced monitoring and conservation efforts targeting the growth conditions of both shrub and arbor forests are imperative to ensure an optimal stand proportion and the stable functioning of the forest ecosystem.
