我国旅游企业普遍存在单体规模小，实力弱，经营管理水平低的弱点，使得我国旅游企业在资金、技术、人力资源、管理模式等方面无法满足未来发展的需要，从而削弱了其进行产品开发、市场拓展、服务质量改善的能力，限制了其在国内国际市场上的竞争力，而企业失去了竞争力就等于人没有了生命力，对一个企业的发展是致命的。而且，由于我国旅游企业资金短缺，技术力量薄弱，长期以来只能依赖于低效率的粗放式经营。这种粗放式的增长方式不但对企业本身造成伤害，而且对自然资源、生态环境构成极大威胁。许多旅游企业在开发旅游资源时缺乏深入的调查研究和全面的科学论证，具有极大的盲目性；还有一些旅游企业急于早日获得经济效益，开发时急功近利，进行掠夺式开发，经营时对资源过度利用，使资源超负荷工作。这些“重开发，轻保护”“重利用，轻保护”的行为造成了许多旅游资源的破坏与浪费。而我国政府及旅游主管部门对这些行为又缺乏完善的监督制约机制，我国还不健全的法律法规体系也使得某些不法分子有机可乘，最终造成了我国旅游业管理混乱，资源浪费的情况，成为制约我国旅游业可持续发展的因素。
(二)发展观念落后，环保意识缺乏成为制约我国旅游业可持续发展的主观因素
长期以来无论是我国政府及旅游主管部门还是旅游理论界都或多或少的存在着这样的认识，即认为旅游业是“无烟工业”，发展旅游业不会对生态环境造成污染。这种认识上的误区直接或间接地影响到了政府及旅游主管部门对旅游开发的监督、规划与管理。加上某些经营者的短视和缺乏社会责任感，导致了对旅游资源的盲目开发与过度利用。另外，由于教育水平及人口素质的差异，我国许多旅游者缺乏环保意识与可持续发展意识。触摸攀爬古迹，在古迹上乱刻乱画，随意丢弃垃圾，在保护区内狩猎、野营的现象屡见不鲜。这些不良行为使许多名胜古迹的原始风貌和存在寿命受到严重威胁，并且加重了旅游区的生态负担，使景区的生态平衡遭到破坏。
(三)生态环境恶化，自然资源破坏成为制约我国旅游业可持续发展的客观因素
1.开发利用不合理导致资源浪费与破坏
长期以来，对旅游资源的掠夺性开发与不合理利用导致许多资源被破坏。
2.水资源锐减并污染严重
水资源锐减一方面使生活用水紧张，另一方面使一些以水体为主的旅游景点消失。水资源锐减的同时，水污染也日趋严重。工业废水、生活废水及旅游区废水不加净化和净化未达标准便排入景区水体，严重污染了水体资源。
3.大气污染并威胁可持续旅游
大气污染往往是跨区域的。它不仅危害人类健康，而且还威胁旅游业发展。二氧化碳导致的温室效应使全球气候变暧，至21世纪30年代全球气温将上升1.5—4.5摄氏度，导致海平面上升25—140厘米，在这种情况下我国许多沿海旅游城市和景区将面临威胁；空气中二氧化硫含量的升高还会导致酸雨的出现，酸雨会毁坏植被，造成土地和水质污染，腐蚀文物建筑，旅游资源质量将受到严重破坏。

二、中国旅游业可持续发展的具体实施策略
（一）强化旅游管理，倡导绿色旅游
1、对旅游城市，旅游景区生态环境进行综合治理
针对我国目前旅游城市，旅游景区存在的空气污染，水污染、垃圾污染和噪音污染等问题，应采取综合治理的方式。
2、对旅游资源开发进行合理有效的规划与管理
良好的旅游环境是旅游业发展的基础。开发旅游资源的目的就是为了美化景观，促进人类与环境的有机结合。因此旅游开发过程中应注意对资源进行合理规划与有效管理。
3、开展生态旅游
生态旅游起源于人们对旅游资源可持续利用的思考。生态旅游的宗旨是既获得适当的利润，又维护自然资源和生态环境的价值。因此，发展生态旅游不仅可以发挥我国自然旅游资源丰富的优势，获取可观的经济效益，而且可以促进基础设施建设，增加就业机会，带动区域经济发展，更重要的是通过生态旅游可以对旅游者进行科普教育与可持续发展教育，提高旅游者的环境保护意识。
(二) 充分发挥政府职能，强化旅游立法执法工作，把旅游可持续发展以法律的形式固定下来

1、加强立法工作，加大执法力度，以法律手段保证旅游业的可持续发展
2、政府运用经济手段对环境问题进行间接控制
政府的经济手段主要包括以下内容：（1）资源环境税（2）排污收费制度（3）押金制度（4）财政补贴（5）环境标志（6）处罚制度
（三）加强环境保护和可持续发展的宣传、教育，提高公民的环保意识和可持续发展的意识

旅游可持续发展是一项浩大繁杂的工程，需要全民齐心协力才能做到。因此我们应加强环境保护和可持续发展的宣传教育，使全体公民树立可持续发展意识。

（四）弘扬中国传统文化，发掘旅游文化内涵，开展文化旅游
文化是旅游的灵魂，旅游本身就是一项广义的文化活动，是人们一种高雅的文化享受。作为旅游客体的自然景观和人文景观都集中了大自然的精华，渗透着人类历史的结晶。增添文化含量将成为旅游业新的增长点和新的价值取向。因此，对旅游资源的文化内涵与特色的开发与保护必是旅游业可持续发展的重要契机。

（五）促进科学技术在旅游业的应用，走“科技兴旅”之路

“科技兴国”是我国社会经济可持续发展的重要内容，旅游业要可持续发展，也必须走“科技兴旅”之路，在开发和经营中将科技和教育放在重要位置，重视知识，重视人才，使旅游业朝规范化、质量型发展。
结论:
旅游可持续发展是我国旅游业发展的必由之路和唯一正确选择，但目前我国旅游业还存在着许多不良因素制约着旅游业的可持续发展。这些问题的解决依赖于科学的规划与管理，依赖于健全的机制，依赖于完善的法律法规体系，依赖于全体公民的共同行动，依赖于科学技术的大力支持。我国旅游业的可持续发展虽任重道远，但前途无限光明，只要全国上下共同努力，我国旅游业必将更加欣欣向荣，蒸蒸日上。

Our country Tourist business universal existence monomer scale is small, the strength is weak, managerial and administrative expertise low weakness, will cause our country Tourist business in aspects and so on fund, technical, human resources, management pattern to be unable to satisfy in the future the need to develop, thus weakened it to carry on the product development, the market development, grade of service improvement ability, has limited it in the domestic international market competitive power, but the enterprise lost the competitive power to be equal to that the human did not have the vitality, to an enterprise's development was fatal. Moreover, as a result of our country Tourist business fund shortage, the technical force is weak, since long can only rely on the low efficiency extensive -like management. Not only this kind of extensive -like the growth way causes the damage to the enterprise itself, moreover to the natural resource, the ecological environment poses the enormous threat. Many Tourist businesses when development tourist resources lacks the thorough investigation and study and the comprehensive scientific examination, has the enormous blindness; Also has some Tourist business will obtain eagerly soon the economic efficiency, when the development is eager for quick success and immediate gain, carries on the plundering type development, when the management to the resources uses excessively, causes the resources excess load work. These “reopen send, light protection” “heavy use, light protection” the behavior has created many tourist resources destruction and the waste. But Our country Government and the traveling Department responsible for the work lack the consummation to these behaviors the surveillance to restrict the mechanism, our country also not perfect laws and regulations system also enables certain unlawful elements to have an opportunity, caused our country tourism management to be chaotic finally, the resources waste's situation, became restricts our country tourism sustainable development the factor. the (2) development idea is backward, the environmental consciousness lacks into restricts our country tourism sustainable development subjective factor regardless of since long is Our country Government and the traveling Department responsible for the work travels the theorists more or less to have such understanding, namely thought that the tourism is “the tourism”, the development tourism will not cause the pollution to the ecological environment. This kind knew the erroneous zone directly or affected the government and the traveling Department responsible for the work indirectly to the traveling development surveillance, the plan and the management. In addition certain operator's superficiality and lacks the social responsibilities, caused with to use excessively to the tourist resources blind development. Moreover, as a result of the educational level and human quality's difference, our country many tourists lacks the environmental consciousness and sustainable development consciousness. Touching climbs up the historical site, engraves randomly in the historical site doodles, discards trash at will, hunts, the camp phenomenon in the protectorate to be common. These misdeeds cause many scenic spot and historic resort the primitive style and the existence life receive the threaten seriously, and aggravated the tourist area ecology burden, causes the scenic area the ecological equilibrium to be destructed. the (3) ecological environment worsens, the natural resource destroys into restricts our country tourism sustainable development objective factor the 1. development to use causes the resources to waste and to destroy unreasonable since long, causes many resources to tourist resources' depletive development and the unreasonable use to destroy. the 2. water resources sharp decline and pollutes serious the water resources sharp decline to cause the domestic water to be intense at the same time, on the other hand causes some by water body scenic site vanishing primarily. Water resources sharp decline's at the same time, the water pollution day by day is also serious. The industrial waste, the life waste water and the tourist area waste water do not purify and the purification have not reached the standard then to disperse into the scenic area water body, has polluted the water body resources seriously. the 3. air pollution and threatens travels the air pollution often is sustainably the cross region. It not only harms the human health, moreover also threatens the tourism development. The carbon dioxide causes the greenhouse effect causes the global climate changes the dim daylight, will rise 1.5-4.5 degrees Celsius to the 2030s whole world temperature, causes the sea level to rise 25-140 centimeters, in this case our country many coast tourist city and the scenic area will face the threat; In the air the dioxide sulfur content will elevate will also cause the acid rain the appearance, the acid rain to be able to destroy the vegetation, will create the land and the water pollution, will corrode the cultural relic construction, the tourist resources quality will receive the heavy damage. two, Chinese tourism sustainable development's concrete implementation strategy (one) strengthens the traveling management, the initiative green travels 1, to the tourist city, the tourist scenic zone ecological environment carries on comprehensive program of public order in view of our country present tourist city, the tourist scenic zone existence air pollution, questions and so on water pollution, trash pollution and noise pollution, should adopt the comprehensive program of public order the way. 2, carries on the reasonable effective plan to the tourist resources development and manages the good traveling environment is the tourism development foundation. The development tourist resources' goal is to beautify the landscape, promotes human and the environment organic synthesis. Therefore in the traveling performance history should pay attention to the resources carries on the reasonable plan and the effective management. 3, development eco-tourism the eco-tourism stems from the people to the tourist resources sustainable use ponder. Eco-tourism's objective is both obtains the suitable profit, and maintains the natural resource and the ecological environment value. Therefore, the development eco-tourism not only may display our country nature tourist resources rich superiority, gains the considerable economic efficiency, moreover may promote the infrastructural facilities, increases the employment opportunity, leads the regional economies development, may carry on the popular science education and the sustainable development education more importantly through the eco-tourism to the tourist, raises tourist's environmental protection consciousness. the (2) full display government function, the strengthened traveling legislation law enforcement work, travels the sustainable development to get down by the legal form 1, to strengthen fixedly the legislation work, increases the law enforcement dynamics, by the legal means guaranteed that the tourism sustainable development 2, the government utilize the economic means to carry on indirect operation to the environment question the government's economic means mainly to include the following content: (1) the resources environment tax (2) the fee-levying for pollution discharge (3) the deposit system (4) the fiscal subsidy (5) the environment symbolized that (6) punishes system (three) to strengthen the environmental protection and the sustainable development propaganda, the education, raises citizen's environmental consciousness and sustainable development consciousness travels the sustainable development is a vast numerous and diverse project, needs all the people to work as one to be able to achieve. Therefore we should strengthen the environmental protection and the sustainable development public education, makes all citizen to acquire the sustainable development consciousness. (four) brings honor to China traditional culture, the excavation traveling culture connotation, the development culture travels the culture is the traveling soul, the traveling is in itself a generalized cultural event, is the people one lofty culture enjoys. Have concentrated the nature essence as the traveling object's natural landscape and the humanities landscape, is seeping the human history crystallization. The addition culture content will become the tourism new point of growth and the new value orientation. Therefore, to tourist resources' cultural connotation and the characteristic development and the protection must be the tourism sustainable development important turning point. (five) promotes the science and technology in the tourism application, walks “the science and technology to be popular the travel” road “to strengthen the nation through science and technology” is our country social economy sustainable development important content, the tourism wants the sustainable development, must walk “the science and technology to be popular the travel” the road, in develops and in the management places the science and technology and the education the key position, takes the knowledge, takes the talented person, causes the tourism to face the standardization, the quality development. conclusion: travels the sustainable development is our country tourism development way that must be taken and the only correct choice, but the present our country tourism also has many bad factors to restrict the tourism sustainable development. These question's solution relies on the science plan and the management, relies on the perfect mechanism, relies on the perfect laws and regulations system, relies on all citizen's combined action, relies on the science and technology support
