摘　　要：概述了自然景区园林化的概念。分析了自然景区园林化对景区内大气．土壤．水体及生物多样性产生的深刻影响。指出：自然景区园林化破坏了自然景观的原真性．整体性．园林化过程减弱了植被对有害气体的吸收能力．使自然景区的大气质量下降；园林化后旅游活动的加剧。降低了土壤中的有机质以及氮、磷等无机营养元素的含量；园林化活动改变了自然景区内水资源的时空分布，污染了水环境；园林化破坏了植被。干扰了野生动物捕食．交配等活动。The concept of gardenisation of natural parks was presented and its profound influences to the air, soil, water and biodiversity were analysed. Such a gardenisation process has been found not only to destroy the authenticity and integrity of the natural landscaping, but also to weaken the vegetation absorbency of deleterious gases resulting in decline of the air quality in natural parks. Increased tourist activities after the gardenisation would reduce the levels of organic matters and some inorganic nutrients such as nitrogen, phosphorus and etc. in the soil. The gardenisation activities could change the space-time distribution of water resources in the natural parks and deteriorate the water environment. Those activities would not only ruin the vegetations, but also disturb the preying and mating of wild animals.
