Effects of landscape composition and configuration on ecosystem services of Baishanzu National Park
【Objective】Vegetation types and structural configurations exhibit distinct characteristics and values in delivering ecosystem services, which are critical for maintaining ecological balance and human well-being. This study aims to elucidate the impacts of forest type composition and landscape configuration changes on ecosystem services (ES), and to clarify the differences in ES provision caused by variations in forest community structure.【Method】Taking Baishanzu National Park in Zhejiang Province as a case study, we quantified four key ES functions—vegetation net primary productivity (NPP), habitat quality, soil retention, and water yield—from 2000 to 2020 using the integrated valuation of ecosystem services and tradeoffs (InVEST) and carnegie-ames-stanford approach (CASA) models. Spatial heterogeneity of ES influenced by vegetation types and forest landscape configurations were analyzed through geographically weighted regression (GWR).【Result】During the study period, total forest coverage increased, while the area of coniferous forests declined significantly. Landscape patterns exhibited central aggregation but fragmentation in western and northern regions. Three ES metrics—water yield, soil retention, and NPP—showed overall upward trends, whereas habitat quality deteriorated.【Conclusion】Changes in forest composition and configuration differentially affected ES: expansion of coniferous-broadleaved mixed forests positively influenced NPP, while increased construction land and bare land negatively impacted water yield and soil retention. These findings provide a scientific basis for optimizing regional ecological management and forest conservation strategies.
