丽江旅游业的蓬勃发展的背后影藏着环境的负面影响，其主要表现为：1）大气

Behind the vigorous development of Lijiang's tourism industry, there are negative environmental impacts, which are mainly manifested as follows: <br>1) The quality of the atmospheric environment has declined. The development of Lijiang's tourism industry first promoted the development of the three major tourism industries, including tourist hotels, travel agencies, and tourism transportation. The increase in tourist facilities, motor vehicles and tourists has caused the atmospheric environmental quality in Lijiang urban areas to generally decline. The garbage generated by tourism is Another source of pollution that pollutes the atmosphere. <br>2) The water environment continues to deteriorate. The development of tourism has caused a large number of pollutants in tourist attractions to appear, resulting in the deterioration of water quality and landscape degradation in the morning area, and even the loss of the water function of tourist destinations. According to the Lijiang Environmental Monitoring Station, due to imperfect sewage pipelines, the potable water in the ancient city has gradually decreased from Class I and Class II water to Class III and Class IV water, mainly caused by excessive ammonia nitrogen and E. coli caused by domestic pollution. . <br>3) The geology and landforms are destroyed. Lijiang's geology and landforms are very fragile, and the discordant development of tourism will cause changes in geology and landforms and even destroy its environmental functions. Although the opening of the Da Su Road in Yulong Snow Mountain in Lijiang is to a certain extent convenient for tourists to reach the snowy mountains and increase the pleasure of travel, the imperfect management of the tourist volume has led to the melting of ice and snow, the continuous rise of snow lines, and the continuous pollution and destruction of snow, which ultimately leads to the four seasons The ecology of the glacier ice treasure house is seriously damaged.

Behind the booming tourism industry in Lijiang lies the negative impact of the environment, which is mainly manifested in:<br>1) The quality of the atmospheric environment decreases. The development of Lijiang tourism, first of all, to promote the development of tourism hotels, travel agencies, tourism and transportation and other tourism industry, increased tourism facilities and motor vehicles and tourists, so that the quality of the atmospheric environment in Lijiang City generally declined, tourism waste is another source of pollution of the atmosphere.<br>2) The water environment is deteriorating. The development of tourism has caused a large number of pollutants to appear in tourist attractions, resulting in the deterioration of water quality and landscape degradation in morning areas, and even the loss of water function in tourist areas. According to Lijiang City environmental monitoring station disclosed, because the sewage pipe is not perfect, drinking water in the ancient city has been gradually reduced from a class of two water to three and four types of water, mainly caused by life pollution caused by ammonia nitrogen and E. coli exceeding the standard.<br>3) The geological features have been damaged. Lijiang's geological features are very fragile, and the disharmonious development of tourism will lead to changes in geological features and even damage its environmental function. Although the opening of Lijiang Yulong Snow Mountain Dasin Road to a certain extent to facilitate tourists to go directly to the snowy mountains, increase the fun of tourism, but the management of tourist traffic is not perfect led to snow melting, snow line continues to climb, snow continues to be polluted and destroyed, resulting in the four seasons glacier ice treasure trove of ecological damage.

The development of Lijiang's tourism industry, first of all, promotes the development of three major tourism industries, such as tourist hotels, travel agencies and tourism transportation. With the increase of tourism facilities, motor vehicles and tourists, the quality of air environment in Lijiang City has generally declined. Tourism garbage is another source of air pollution.<br>2) The water environment is deteriorating. With the development of tourism, a large number of pollutants appear in the scenic spots, resulting in the deterioration of water quality and landscape degradation in the morning area, and even the loss of the water function of the tourist destination. According to the environmental monitoring station of Lijiang City, due to the imperfect sewage pipeline, the drinking water in the ancient city has been gradually reduced from class I and II to class III and IV water, mainly caused by excessive ammonia nitrogen and Escherichia coli caused by domestic pollution.<br>3) The geology and geomorphology were destroyed. Lijiang's geology and geomorphology are very fragile. The disharmonious development of tourism will lead to the change of geological landform and even destroy its environmental function. Although the opening of Dashu road in Yulong Snow Mountain, Lijiang, to a certain extent, is convenient for tourists to go directly to the snow mountain and increase the pleasure of tourism, but the imperfect management of tourist volume has led to the melting of ice and snow, the continuous climbing of snow line, and the continuous pollution and destruction of snow, resulting in serious ecological damage to the ice treasure house of four seasons glacier.<br>
