摘要
指出了京密引水渠及怀柔水库是北京市重要的饮用水源保护地,引渠两岸和库区的水源防护林在涵养水源、保持水土、净化水质方面发挥着不可替代的作用,但是目前水源防护林面临着不同程度有害生物的侵害,在对有害生物进行防治时,防治措施要尽量避免对水源环境的影响。为此,以京密引水渠防护林及怀柔水库水源涵养林为例,从林分结构分析了其有害生物的发生原因,总结了饮用水源保护区内林木有害生物的生态治理的措施,提出了水源防护林有害生物生态治理模式,以物理、生物的防治措施为主,合理优化植物布局,重视整个生态环境中各物种间的平衡,科学实施防治技术,确保饮用水源安全,可为相关人员提供借鉴。
The Jingmi Diversion Canal and Huairou Reservoir are important drinking water source protection 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 purifying 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.
