: 1. What are the main characteristics of tourism resources in the middle and lower reaches of the Yangtze River?

1. Upstream (about 4500 km): Most rivers pass through plateaus, mountains and canyons, with obvious characteristics of plateau and mountain rivers. Here, the river bed gradient is large, the river is abundant, the water is swift and the water resources are abundant.

2. Middle reaches (about 1000 km): The river course is tortuous, the river surface is wide, the riverbed gradient is steep, the water flow is slow, and there are many tributary lakes. Rainwater has a significant impact on the water level and discharge of the main stream of the Yangtze River, and plays an important role in regulating the water quantity of the main stream of the Yangtze River.

3. Downstream (800km): The river is wide and deep, with short tributaries, dense water network and numerous lakes, which has little influence on the water quantity of the Yangtze River.

2. Several problems in the development of tourism resources in the middle and lower reaches of the Yangtze River

In, the Arabian Peninsula and the plain area in the middle and lower reaches of the Yangtze River were located at roughly the same latitude. Affected by land and sea factors, the climate is very different and the natural landscape is also very different. The Arabian Peninsula has a tropical desert climate, which appears on the west coast and inland areas of the mainland where the Tropic of Cancer passes. Under the influence of subtropical high pressure area and trade wind area, the airflow sinks and the precipitation is less, forming a desert landscape. There are significant differences between land and sea in the middle and lower reaches of the Yangtze River, with monsoon climate, abundant heat, abundant precipitation and contiguous paddy fields. Therefore, it was chosen as B.

3. Characteristics of tourism resources in the middle and lower reaches of the Yangtze River

The middle and lower reaches of the Yangtze River is the third largest plain in China. Including Jianghan Plain, Dongting Lake Plain, Poyang Lake Plain, Anhui Riverside Plain and Yangtze River Delta. It is alluvial from the Yangtze River and its tributaries. It covers an area of about 200,000 square kilometers. Features:

1. is mainly formed by alluvial sediment carried by the Yangtze River and its tributaries. The terrain is low, and the lower part is below 50 meters above sea level.

2. Freshwater lakes in China are the most concentrated areas, with rivers and tributaries criss-crossing, covering plains and lakes. It is called Zeguo Water Town.

3. China is an important agricultural base, an important grain, cotton and oil production base and a famous land of plenty.

4. Subtropical climate zone with mild climate and long frost-free period.

5. The soil is mainly yellow brown soil or yellow cinnamon soil. The southern edge is red soil, and most of the plains are paddy soil.

The middle and lower reaches of the Yangtze River include Anhui, Zhejiang, Jiangsu, Shanghai, Hubei, Hunan and Jiangxi provinces. This is one of the three plains in China, with dense river networks and abundant water resources, which is suitable for the growth of rice and other food crops, so it is called the land of plenty. There are Yueyang Tower, Yellow Crane Tower, Wangteng Pavilion, Dongting Lake, Panyang Lake and other cultural landscapes, and the tourism industry is also very rich.

4. The development of tourism in the middle and lower reaches of the Yangtze River

The natural water system and criss-crossing artificial canals in the middle and lower reaches of the Yangtze River make this area the densest river network area in China. The most important river in this area is the Yangtze River and its tributary Hanjiang River, and most of the rivers in this area are alluvial rivers.

There are many freshwater lakes scattered on the plain in the middle and lower reaches of the Yangtze River. The lake area is about 20,000 square kilometers, which is equivalent to 10% of the plain area. There are more than 300 great lakes 1.000, including small lakes, with an area of1.20 thousand square kilometers, accounting for more than 20% of the plain area of the two lakes. It has the most lakes in China. Jianghan Plain is called Thousand Lakes in Hubei, and Yangtze River Delta is also called water town, pastoral lake and depression, accounting for 13.4% of the total land area of the delta. In addition to Taihu Lake, there are more than 50 large lakes/kloc-0 with an area of more than 1000 mu, and thousands of lakes and docks with an area of less than 1000 mu.

Among the lakes in the middle and lower reaches of the Yangtze River, Poyang Lake, Dongting Lake, Taihu Lake, Hongze Lake and Chaohu Lake are relatively large. They play the most important role in the Yangtze River and its downstream.

The whole Yangtze River is characterized by its surging Yangtze River, towering mountains and majestic tigers. It is the mother river of great China and the third largest river in the world.

3. The Yangtze River is the longest river in China, with the largest drainage area, the largest number of provinces and the largest amount of water resources, including the Three Gorges in China, Nanjing in China, Shanghai in China, Yangtze River Delta in China, the largest tributary, Poyang Lake in China and Chongming Island in China.

5. The tourist areas in the middle and lower reaches of the Yangtze River include

The middle and lower reaches of the Yangtze River mainly include Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang and Shanghai. There are 10 world heritages in this area, namely: Huangshan (Anhui, 1990, 65438+ February talk, natural and cultural heritage), Wulingyuan Scenic Area (Hunan, 1992, 65438+ February talk, natural heritage), and ancient buildings in Wudang Mountain. Art Garden, Furong Garden, Canglang Pavilion, Lion Forest, Retreat Garden, 2000165438+1October, Cultural Heritage) Xidi, Hongcun (Anhui, 2000165438+1October,

From 20 10 to 20 10, the largest rivers in China flow through provinces and cities: Qinghai (Qinghai), Tibet (Tibet), Sichuan (Sichuan), Yunnan (Yunnan), Chongqing (Chongqing), Hubei (Hubei), Hunan (Hunan), Jiangxi (Jiangxi), and Hunan.

The Yangtze River is the third longest river in the world, with a total length of 6,387 kilometers and a drainage area of 6,543,800 square kilometers. The Yangtze River originates in the southwest of Gladding Cave in Tanggula Mountain of Qinghai-Tibet Plateau. It is the largest river in China and the third largest river in the world after the Amazon River and the Congo River.

The Yellow River basin starts from Bayan Kara in the west, reaches Bohai Sea in the east, Qinling Mountains in the south and Yinshan Mountain in the north, with a basin area of 752,000 kilometers. The Yellow River originates at the northern foot of Bayan Kara on the Qinghai-Tibet Plateau, flows through nine provinces and regions including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong, and joins the Bohai Sea in Kenli County, Shandong Province, with a total length of about 5400km.

From Heyuan to Tuoketuo, Inner Mongolia, the upper reaches, in which most areas above Lanzhou have good vegetation coverage; There are many valleys in the main stream from Mazhi to Qingtongxia, which are rich in hydropower resources. Below Xia Qing is Hetao Plain, where irrigation is developed and can be used for shipping. Tuotuo-Taohuayu in Henan Province is in the middle reaches and is rich in hydropower resources. The two banks are the Loess Plateau, with scarce vegetation and serious soil erosion, which is the main source of flood and sediment in the Yellow River.

Taohua Valley is in the lower reaches of the estuary, and most of the river banks have built levees. Sediment deposition makes the riverbed generally 3~5m higher than the ground on both banks, and most of them reach 10m, so it is called suspended river. There are many irrigation areas along the coast, and the main stream is navigable. Near the estuary, the Yellow River's waterway into the sea is continuously silted, extended and diverted, which has a strong land-building effect. There are ten tributaries with a basin area of more than 10 thousand kilometers, of which Weihe River has the largest area and water volume.

6. What are the main tourist features of the tourist areas in the middle and lower reaches of the Yangtze River?

The Yangtze River has a long history, with a total length of 6,300 kilometers. Traditionally, it is divided into three sections, with Hubei Heyuan-Yichang as the upstream; Yichang-Jiangxi Hukou is the middle reaches; Below the estuary is the downstream. The three major reaches of the Yangtze River are divided according to the geographical environment and hydrological characteristics of the main stream. Function (brief description):

1. Upstream (about 4500 km): Most rivers pass through plateau, mountain and canyon areas, with obvious characteristics of rivers in plateau and mountain valley. Here, the river bed gradient is large, the river is abundant, the water is swift and the water resources are abundant.

2. Middle reaches (about 1000 km): The river course is tortuous, the river surface is wide, the riverbed gradient is steep, the water flow is slow, and there are many tributary lakes. Rainwater has a significant impact on the water level and discharge of the main stream of the Yangtze River, and plays an important role in regulating the water quantity of the main stream of the Yangtze River.

3. Downstream (800km): The river is wide and deep, with short tributaries, dense water network and numerous lakes, which has little impact on the water quantity of the Yangtze River.
