Beijing topographic survey paper
(1) Beijing is located on the northern edge of North China Plain, bordering Yanshan Mountain in the north and Xishan Mountain in the west.

(2) Beijing has a typical temperate monsoon climate, with dry and windy spring, high temperature and rainy summer, sunny and pleasant autumn and cold and dry winter. The annual average temperature in Beijing is 10 ~ 12℃, and the seasonal distribution of precipitation is uneven. Most of the precipitation in the whole year is concentrated in summer, and there are often heavy rains in July and August.

(3) Summer in Beijing is characterized by hot weather and concentrated rainfall. For example, in 1959, the annual precipitation in Beijing was as high as 1 400 mm (the average precipitation for many years was only over 600 mm), and the rainfall in July and August was1235 mm. Due to the influence of topography, the windward slope of the southeast mountainous area (Jundushan) in Beijing,

(4) The terrain of Beijing inclines from northwest to southeast. The main rivers are Yongding River and Chaobai River, both of which belong to Haihe River system and flow into the sea from northwest to southeast.

(5) Miyun Reservoir, known as "a basin of clear water in Beijing", is located in the upper reaches of Chaobai River. Beijing is densely populated, with developed industries, and the shortage of water resources is becoming increasingly obvious. The main solutions are: ① saving water and preventing water pollution; (2) Developing water-saving technology to improve the efficiency of water resources utilization; (3) Planting trees and building reservoirs; ④ Construction of inter-basin water transfer project; ⑤ Raise water price, etc.

So, the answer is: (1) mountain; (2) Less rain; Rainy; (3) Southeast slope; (4) Yongding; Northwest flows to southeast; (5) Miyun; Save water and prevent water pollution.
