Geography in the second day of junior high school, urgently seeking

1. Xiao Li's hometown belongs to mountainous areas, and the proportion of this terrain in the whole country is 5 1.9%.

2. Xiao Li's hometown is an underdeveloped area, and the reasons that restrict the local economic development are: rugged mountain roads and poor traffic conditions; The environment is closed and people's thoughts are backward; Cultivated land resources are insufficient.

Li Can Jr. changed the backwardness of his hometown by participating in highway construction, actively promoting agricultural products and promoting tourism in his hometown.

Second, China's topography is complex and diverse, with vast mountainous and plateau areas. This will have an impact on agricultural production in China: on the one hand, various landforms provide favorable conditions for China to develop agriculture, forestry and animal husbandry by-products according to local conditions; On the other hand, there are many mountains and few plains, which also brings difficulties to large-scale commercial production and production management; At the same time, due to the rugged terrain and traffic congestion in mountainous areas,

Economy and culture are often relatively backward, and cultivated land resources are insufficient.

Third, the topography of China is high in the west and low in the east, showing a ladder-like distribution. What impact will this topographical feature have on China's natural resources?

① Impact on climate: The westerly belt passing over China was forced to split into two branches in the west and meet over Japan. The eastward movement of the westerly trough in the south branch is the main source of precipitation in the southwest and east of China in east, spring and autumn, which makes the south of China not very dry in winter and spring, and also leads to drought in the northwest, because the Qinghai-Tibet Plateau prevents it from obtaining water vapor from the Indian Ocean.

② Impact on the river: The river flows from west to east to the sea.

(3) Impact on traffic: the eastern plain has a large area and convenient transportation, while the western part is mountainous and inconvenient.
