The Jingmi Diversion Canal and Huairou Reservoir are important drinking water source protec-tion areas in Beijing.The water source protection forests on both sides of the diversion canal and in the reservoir area play an irreplaceable role in nourishing water sources,maintaining soil and water,and pu-rifying water quality.However,currently,the water source protection forests are facing varying degrees of harmful organisms.When controlling harmful organisms,prevention and control measures should try to avoid the impact on the water source environment as much as possible.Therefore,this paper takes the protective forest of the Jingmi Water Diversion Canal and the water source conservation forest of the Huairou Reservoir as examples,analyzes the causes of harmful organisms from the forest structure,summarizes the ecological management measures of harmful organisms in the forest in the drinking water source protection area,proposes the ecological management mode of harmful organisms in the water source protection forest,focuses on physical and biological prevention measures,reasonably optimizes plant layout,and emphasizes the balance between various species in the entire ecological environment.Prevention and control technologies are scientifically implemented to ensure the safety of drinking water sources,hoping to provide a reference for relevant personnel.
