(1) The terrain on both sides of the Tuojiang River is rugged and there is little flat land; It is hot and humid in summer, and the diaojiao building is conducive to heat dissipation and ventilation and keeps dry; Can prevent the invasion of poisonous snakes, wild animals and other animals; Conducive to river flood discharge; Convenient for water traffic. (6 points for any answer at 3 o'clock)

(2) advantages: collecting tickets can control the number of tourists; Improve the tourism quality of tourists and protect the local tourism ecological environment. (2 points)

Disadvantages: high ticket prices will affect the enthusiasm of tourists and lead to a decrease in the number of tourists; Affect the development of related industries and reduce tourism income. (2 points)

Test analysis:

(1) Because of the rugged terrain and little flat land, the construction of the diaojiao building can adapt to the undulating surface and is relatively firm; The climate in this area is hot and humid, and the diaojiao building is higher than the ground, which is conducive to heat dissipation and ventilation and keeps it dry; There are many vegetation in this area, among which there are many animals such as poisonous snakes and wild animals, and the high diaojiao building can prevent its invasion; Because the diaojiao building is higher than the ground, it is beneficial to flood discharge in the river and convenient for water traffic.

(2) On the positive side, due to the limited capacity of the local environment, collecting tickets can control the number of tourists, improve the quality of tourists' travel and reduce the damage to the local ecological environment. From the analysis of unfavorable conditions, the higher tickets and the lower number of tourists will reduce the development of related industries and affect the local economic development.
