Assessment of Anthropogenic Impacts on Water Quality and Microbial Communities in the Heilongjiang Maolan Gou National Nature Reserve.

ABSTRACT: Freshwater ecosystems within protected areas play a vital role in maintaining biodiversity and ecological stability, yet they are increasingly threatened by anthropogenic disturbances such as agriculture and tourism. Understanding the impacts of human activities on water quality and microbial community dynamics is essential for the effective conservation and management. This study investigates the spatial variability of water quality and microbial communities across the core, buffer, and experimental zones of the Heilongjiang Maolan Gou National Nature Reserve. Twelve water samples were collected and analyzed for key physicochemical parameters (turbidity, electrical conductivity (EC), chemical oxygen demand (COD), biochemical oxygen demand (BOD), NH₄⁺, PO₄³
