.What are the characteristics of river landscape?

Water is the most active factor in nature and the most vivid material in nature. It constitutes the water scenery that people enjoy and forget to leave. Shape, shadow, sound, light, color and taste are the six attractive elements of water. Water exists in various forms in nature. Water scenery can generally be divided into five categories: river scenery, lake scenery, spring and waterfall scenery, and sea area. Landscape, glacier landscape.

1. River scenery

During the flow of rivers, the surface of the earth is transformed, which is called the action of flowing water. This is a typical external force, mainly manifested by erosion and transportation. ,accumulation. These three methods are carried out simultaneously, but for a certain river, different river sections often express different forms. For example, the upper reaches are dominated by erosion, the middle reaches are dominated by transportation, and the lower reaches are dominated by deposition, so different scenery is formed from the source of the river to the mouth of the river. Example: Names and landscapes of different river sections in the scene

Source: The glaciers and snow-capped mountains above Yushu in Qinghai, desolate and mysterious;

Upstream: Yushu-Yichang Canyon Rapids in Hubei, majestic Deep and deep;

Midstream: Yichang----Jiangxi's meandering flat lake, bright and beautiful;

Downstream: Hukou-----Jiangsu's Zhenjiang water town Zeguo, misty rain ;

Estuary: Zhenjiang 1. Lake landscape

Lake: a relatively wide body of water formed by accumulated water in depressions on the land surface. Lakes are natural water storage basins on land and important forms of land water. Lakes are tourism resources that fully embody the characteristics of shape, shadow, sound, light and color in water landscapes. People often use "mirror, pearl" to describe lake landscapes ( 2) Tourism functions of lakes

Lakes are an excellent place for water tours and recreation;

Lakes are an ideal destination for lakeside sightseeing;

Lakes are an ideal place for vacation and cultivation Second, spring and waterfall landscape

(1) Spring

Spring is a natural outcrop where groundwater flows out of the surface and is a way of excreting groundwater.

There are many types of springs. The springs with great tourism value mainly include hot springs and mineral springs.

Hot springs (water temperature comes from geothermal heat)

Distribution: Consistent with volcanic and seismic zones, the world is mainly concentrated in the Pacific Ring of Fire and the Mediterranean-Himalayas. Japan is a country with many volcanoes and a big hot spring country, with more than 20,000 hot springs in Japan. In addition, New Zealand and Iceland are also home to hot springs, and both have achieved great success in the development and utilization of geothermal resources. The distribution of hot springs in my country: Tibet (more than 630 places), Yunnan (more than 480 places), Guangdong, Fujian and Taiwan (more than 100 places).

Mineral spring: refers to mineralized spring water that contains certain minerals and has medical and drinking value. Generally speaking, mineralized spring water is easily produced in areas where granite is developed. Generally speaking, hot springs are mostly mineralized springs, but mineralized springs are not necessarily hot springs. In Hainan Province of my country, granite is widely distributed, so the drinking mineral water is widely distributed, has large reserves and is of high quality.

Functions of spring water:

General functions: drinking, irrigation, power generation, wine making, extraction of industrial raw materials, etc.

Tourism functions: aesthetics, medical care, tea tasting and brewing, etc.

(2) Waterfalls

Types of waterfall formation:

Tectonic waterfalls: formed by uplift, fracture, and subsidence of strata

Lava Type waterfalls: formed by volcanic eruptions and lava flows blocking rivers

Accumulation waterfalls: formed by mountain collapse and mudslides blocking rivers

Accumulation waterfalls formed by glacier erosion: soft and hard river bed rocks Different, the flowing water invades for a long time

The scenery of the three sea areas

The ocean:

Vast, vast, mysterious; the cradle of life, the hometown of wind and rain; the source of resources Treasure houses, sea transportation channels, and collections of scenery provide a rich world of tourism for mankind.

There are three main categories of marine scenery with tourism significance: coastal scenery (mountainous coast, plain coast, biological coast), submarine scenery, and tidal scenery.

A Coastal Scenery

1. Mountain Coast (Bedrock Coast)

Bedrock Coast is composed of hard rocks with clear outlines, strong lines and majestic It not only has masculine beauty, but also has an ever-changing charm. It is one of the main types of coasts. Bedrock coasts often have protruding headlands. Between the headlands, bays are formed that go deep into the land. The headlands and bays alternate with each other and stretch endlessly. Absolutely, the coastline is very winding.

Bedrock coasts are widely distributed in my country's Shandong Peninsula, Liaodong Peninsula and Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Qiong and other provinces south of Hangzhou Bay. The most spectacular scenery on the bedrock coast is from The huge waves rushing from the sea hit the cliffs and filled the water columns, making bursts of roar.

2. Plain coast

The plain coast was once known as the "sand coast" and is composed of huge thick and loose sediments. The shoreline of this kind of coast is straight and monotonous, the terrain on the shore is flat, there are many sandbars and shoals in some places, the intertidal zone is wide, and there is a lack of natural harbors and islands.

Features: It is composed of fine-grained silt sand and silt sediments;

It has an extremely low and flat terrain with a slight slope toward the sea. The ground slope is very small, about 1/1000 to 1/4000;

Its inner edge is often connected with the alluvial plain;

Coastal dynamics are very active, and the erosion and siltation of the coastline changes rapidly, so the coastline is very Unstable.

Plain coasts are mainly developed in tectonic subsidence areas, and various marine topography are formed under the action of waves. Tide also plays an important role in the formation of the original coast. In areas with relatively large tidal range and strong tidal action, muddy shoals and tidal deltas are often formed.

Distribution area: my country has up to 2,000 thousand The plain coasts are mainly located on the west coast of the Bohai Sea and the Jiangsu coast on the west coast of the Yellow Sea. In addition, there are also small areas distributed on the periphery of the Songliao Plain and on the tops of some estuaries and bays in Zhejiang, Fujian, and Guangdong.

3. Biological coast

Definition: Coast formed by biological action.

Type: wetland swamp coast, mangrove coast, coral reef coast

Typical landscape: Mangrove coast and coral reef coast in tropical and subtropical areas are the most typical. Erosion caused significant height differences in the river bed.
