Question 2:B

Question 3: A.

Question 1: Hangzhou West Lake is located in the eastern plain of China, with a flat terrain; The climate is subtropical monsoon climate; High vegetation coverage. Affected by natural environmental conditions, the hydrological characteristics of the four major rivers in this area mainly include large flow in summer and autumn, obvious flood in summer, large seasonal variation of water level, mainly atmospheric precipitation recharge, small sediment concentration, no ice age and relatively flat water flow. The average temperature in winter in this area is higher than 0℃, so the rivers are not frozen and there is no ice age in winter, so this question should be selected as ① ② ③.

Question 2: Hangzhou West Lake is located in the south of China. According to the division of China regional cultural areas, it should belong to Jiangnan water town culture.

Question 3:RS is mainly used for the acquisition of geographic information data, GIS is mainly used for the management, query, analysis and application evaluation of geographic information data, GPS is mainly used for space development, and GPRS does not belong to geographic information technology. Remote sensing (RS), which can be used for resource investigation, environmental monitoring and natural disaster prevention and control monitoring, should be used to understand the pollution or sediment status of the West Lake.
