The Yangtze Kiang Basin can be divided into the following regions from its source to mouth-

Szechuan Basin:

This basin extends from the source of the River Yangtze, Ichang and is surrounded by Szechuan Alps, Tibetan Plateau and Yunnan Plateau. In the Tertiary Age there was a lake here which got filled up and gave rise to this lowland.

This part of the basin is also called the Red Basin due to the presence of red sandstone. The climate of this region is pleasant, it is densely populated and prospers in agriculture.

Middle Yangtze Basin:

This part of the basin extends from Ichang to Hunan. It consists of a large plain, innumerable lakes and low hills. As this region is composed of new alluvium it is highly suitable for agriculture and is known as the ‘Granary of China’.

Hunan is also called the ‘Rice Bowl of China’ for its considerable production of paddy cultivation. Other crops produced are wheat, cotton, sugarcane, oilseeds etc.

Delta region:

The Yangtze Kiang Delta region extends from Hunan to the China Sea. It is a plain area and intensive agriculture produces loads of crops here. The river forms a huge delta and divides itself into a number of distributaries before draining into the China Sea.

Many places have been reclaimed from the sea and so this delta region is also called the ‘Holland of China’. The Grand Canal which is located here is the longest canal in the world.

Shanghai, the largest city and port of China, is located in this region. This city is known as the ‘Manchester of China’ due to advancement in the textile industry.

The Szechuan Basin constitutes the upper course of the Yangtze River which passes through the Szechuan Province. It extends from the source of the Yangtze River to Ichang.

It is mainly a lowland bound by different plateaus and mountains on all sides and has been. formed by the depositions brought down by the four tributaries of the Yangtze River.

The rivers which flow over this basin are Yalung Jiang, Min Jiang, Tuo Jiang, Jialing Jiang, Jinsha Jiang, etc. The climate prevailing over this region is pleasant and due to the predominance of red soil in the region, it is also called Red Basin.

This region prospers in agriculture and is densely populated.

Question 2. What are the reasons for the development of agriculture in the Yangtze Klang Basin?
Answer:

The reasons for the development of agriculture in the Yangtze Klang Basin:

The Yangtze Kiang Basin is one of the most agriculturally developed regions in China. The reasons for the development of agriculture in this region are-

  1. Plain land formed by the rivers.
  2. Highly fertile soil
  3. Favourable climate for cultivation
  4. Availability of sufficient cheap and skilled labour
  5. High demand of agricultural products
  6. Government aids.

Apart from these, high yielding variety of seeds, excellent fertilisers, modern tools and equipment for cultivation, provisions for modern agricultural training, etc are the main reasons for the development of agriculture in the region.

The Yangtze Kiang River basin is the most agriculturally rich region in China. Out of the total agricultural production of China, 70% of wheat and more than 50% of the other crops is produced in this region.

Question 3. Which region is called ‘The Granary of China’ and why? Or, Why is the Hunan Province known as the ‘Rice Bowl of China’?
Answer:

The Granary of China:

The Middle Yangtze Kiang Basin in general or the Hunan Province in particular, the most agriculturally rich region in China, is also the largest geographical region in China.

Favourable topography, moderate temperature and rainfall, fertile soil, dense population and government aid help in the abundant production of different types of crops (wheat, paddy, sugarcane, cotton, pulses, tobacco, oilseeds, etc.) across the river basin.

Out of the total crop productivity in China, 70% is of paddy and more than 50% is of wheat. Apart from these, a huge number of mulberry trees are grown for the breeding of silkworms.

Thus, this agriculturally rich Central or Middle Yangtze Kiang Basin is also known as the ‘Granary of China’.

Question 4. Which region is called ‘The Holland of China’ and why?
Answer:

The Holland of China:

The delta region of the Yangtze Kiang is called the ‘Holland of China’, because, like the northwestern part of Holland (now the Netherlands), the Yangtze Kiang delta region is also a low flat plain and there are a number of polders (tracts of lowlands reclaimed from the sea) in this region.

A large number of canals have been dug out for convenience in irrigation and cheap means of water transport similar to that in Holland.

Although the region is not rich in minerals like that of Holland, it is rich in agriculture and industry and is densely populated.
