8UL5gTt;_1N0【中文摘要】 自20世纪60年代以来,旅游业的环境影响一直是国际学术界研究的热点问题,学者们在不同地区运用实证法和定性描述法就旅游业对不同环境系统(如自然环境、社会文化环境等)或某一环境系统中某些因子的影响进行了大量卓有成效的研究,但目前仍少有学者就某一地区旅游业对自然环境、社会环境的影响以及该地区居民对旅游业环境影响的心理响应展开全面系统的综合研究,探讨在旅游业的环境影响作用下旅游地环境系统之间的相互作用机理,建立起具有推广应用价值的旅游业环境影响的综合评价指标体系。鉴此,本研究以三峡库区为研究对象,综合运用实验分析、现场调查、比较研究、模型模拟等多种方法,全面系统地剖析了旅游业对三峡库区自然环境、经济环境和社会文化环境的影响,探讨了三峡库区居民对旅游业环境影响的心理响应水平,构建了三峡库区旅游业环境影响的综合评价体系以及旅游业环境影响的控制系统。 (1)旅游活动对三峡库区的水环境、土壤生态环境、植物及其生境的消极影响明显。①旅游业的发展直接导致三峡库区旅游用水需求的膨胀,加剧三峡库区水资源供应的紧张局势;旅游生活污染量的增加,加重三峡库区污废处理设施的运行负荷和水体质量恶化的潜在威胁。三峡库区旅...更多游者人均耗水量为290L/d,是当地城市居民的人均生活综合用水量的1.23倍;过夜游客的日均用水量是当地城市居民生活综合用水量的1.55~12.27倍,不断增长的旅游用水需求势必加剧三峡库区旅游城镇尤其是没有江河水源补充的山地旅游区水资源供给的紧张局势。旅游者人均产生的生活污水超过260L/d,生活垃圾900g/d,分别高出城市居民生活污水和生活垃圾产生量的20%和80%。与此同时其增长速度大超过当地城市居民的增长幅度,在一定程度上加重了污废处理设施的运行负荷。大量分散而无法搜集或者目前尚未采取任何处理措施的旅游废弃物和直接排入江中的旅游船舶废弃物是三峡库区最具有威胁力的水体污染源。②旅游活动的冲击不同程度地改变了土壤的物理化学因子。随着旅游活动强度的增加,土壤硬度、容重和pH值呈逐渐上升趋势,土表的枯枝落叶层、腐殖质层、土壤的孔隙度、含水量、有机质、全氮和碱解氮则呈逐渐减少趋势。土壤的全磷、有效磷、全钾、速效钾等因子的增减变化与旅游活动强度的增减没有对应关系,对旅游活动的冲击缺乏响应。地理环境因子坡度与土壤硬度、容重、pH值呈负相关,与枯枝落叶层厚度、腐殖质层厚度、孔隙度、含水量、有机质、全氮、碱解等呈正相关。坡向与土壤硬度、容重、pH值呈正相关,与枯枝落叶层厚度、腐殖质层厚度、孔隙度、含水量、有机质、全氮、碱解氮等呈负相关,因为这些地理环境因  还原水利论文/Z)uk~Vi~:Y%}3d~

+M~eK Q&h8F~0【英文摘要】 Since the 1960's, the impacts of tourism industry on the environment has long been a topic for heated debate in the international academic circle. Scholars researched the impacts of tourism industry on different environmental systems (such as physical environment, social environment, etc.) or factors in environmental system in different areas and procured fruitful achievement. But now, some researchers studied synthetically the tourism impacts on physical environment, social environment and local residents' psychological responses on the of tourism impacts in same area, probed into the interactions between different environmental systems under tourism impacts and established an applicable integrated evaluation system (IES) of the tourism impacts on the environment. Therefore, this paper focusse on the research of impacts of tourism industry on physical, economic and socio-cultural environment in the Three Gorges Reservoir Area, the research of residents' psychological responses on the ...更多tourism impacts, and the establishment of IES and control system of tourism impacts by adapting experimentation, field-survey, comparative research and model design, etc..(1)There are evident facts that water, soil, vegetations and their environment for existent are influenced negatively by the tourists' activities in Three Gorges Reservoir Area. (1)The development of tourism industry results in the increase of water need, of water supply, of pollutants by tourism industry, which has aggravated the burthen of sewage treatment facilities and exacerbation of water quality in the Three Gorges Reservoir Area. In this area, the average use of water 290 liters daily per tourist is 1.23 times as much as townsmen, the average use of water daily per overnight tourist is from 1.55 to 12.27 times as much as townsmen. The increasing need of water from tourism industry should beget the shortage of water supply of tourism cities or towns, especially mountainous tourism zones that lack due supply of water. Sewage of 260 liters daily per tourist is 20 percent more than townsmen, and rubbish of 900 grams daily per tourist is 80 percent more than townsmen, their increase speed is faster than that of townsmen. Much sewage by tourists or tourist ships that isn't gathered and treated, which is dumped into rivers, is a most dangerous pollutant to the rivers in the Three Gorges Reservoir Area. (2)Soil physical and chemic elements  还原
