Tropical rainforest zone and tropical monsoon forest zone

The tropical monsoon forest zone is influenced by the tropical monsoon climate.

It is a zonal closed forest vegetation formed under the tropical climate conditions of alternating dry and wet seasons. The main difference between the vegetation of tropical monsoon forest and tropical rainforest vegetation is that the community structure is simplified, the tree layer is reduced to two layers, at least some species have no leaves in the dry season, tabular roots, stem flowers, woody vines and epiphytes are usually far less developed than rainforests, and the understory shrubs are dense and rich in species.

Tropical monsoon forests are subject to climate change and can be divided into two types: deciduous monsoon forests and semi-evergreen monsoon forests (or evergreen monsoon forests). Deciduous monsoon rainforests are distributed in tropical areas with annual rainfall of 500 to 1500 mm and monthly rainfall of less than 100 mm for more than 5 months. The lower trees are mostly evergreen.

Typical deciduous monsoon forests are pumped forests. The semi-evergreen monsoon rainforest has two layers of closed tree layers, distributed in the annual rainfall of 1500 2500 mm, the dry and wet seasons are obvious, but the high temperature and rainy season, low temperature and low rain season are combined, the area with good hydrothermal effect has two layers of closed tree layer, and some of the upper trees belong to the species of fixed deciduous leaves, and the amount of defoliation and the duration of no leaves are quite different in different drought years. The lower layer is still composed of evergreen species, and lianas are generally more abundant.

There is a lack of strict boundaries between the two types of vegetation in tropical monsoon forest and tropical rainforest, showing a gradual transition continuity. Evergreen monsoon rainforests differ less from tropical rainforests during the rainy season, but a small number of tall trees can be leafless for a few days to a few weeks during the short dry season. The more primitive the community, the wetter the community, the fewer deciduous tree species, and the closer the appearance of the community is to the tropical rainforest.

Monsoon forests are found on the periphery of tropical rainforests with three discontinuous large areas, namely Southeast Asia and the Indian Peninsula, West Africa, northern South America, and the Caribbean. In the tropical areas of southern China, there are various types of monsoon forests, and the main components are dipterocarp and acnebus, ceibaceae, kapok, conjunaceae, pinch, five-flowered and ficus of the mulberry family.

Due to the strong influence of frequent human activities on monsoon forests, many monsoon forest communities are secondary in nature and even transformed into savanna vegetation caused by human action.

Tropical rainforests, where plants can grow all year round without significant seasonal changes.

In tropical monsoon forests, plant growth varies seasonally because of significant changes in precipitation and temperature, which are fast in the rainy season and when the temperature is high, and slow in the dry season and when the temperature is low. In fact, many crops can be grown in both regions.

The reason why there is a tropical monsoon forest is because in some places, the temperature and precipitation are suitable for the growth of tropical plants, but there are obvious seasonal changes so that the tropical monsoon forest is formed, in general, the tropical monsoon climate distribution of the tropical rainforest is mostly the tropical monsoon forest, and the mountain windward zone located at a slightly higher latitude also has its distribution, such as the tropical monsoon forest in the east of the island of Madagascar, the tropical monsoon forest on the east side of the Great Dividing Range in the northeast of the Australian continent, and so on.

Tropical rainforestsThe difference between the zone and the tropical monsoon forest zone is:

First, tropical rainforests are hot and rainy all year round, and leaves generally do not fall off; Tropical monsoon forests have a clear distinction between wet and dry seasons, when the main tree species lose their leaves and new leaves grow again during the rainy season.

Second, the tropical rainforest has a complex structure, which can be divided into 4 or 9 layers, with a wide variety of plants, and each species is relatively strong, and there is no obvious dominant species; Compared to tropical rainforests, tropical monsoon forests have a relatively simple structure, fewer plant species, and are often one species with a distinct advantage over others.

Thirdly, the competition of plants in tropical rainforests is cruel, and there are strangled plants, and the phenomenon of tabular roots, pillar roots and old stems and flowers is more common. There are no strangled plants in tropical monsoon forests, and the phenomenon of slab roots and old stems growing flowers is not common.

Fourth, the vegetation on the surface of tropical rainforest is not as much as that of tropical monsoon forest, and there are much more vine, epiphytic and parasitic vegetation in a single layer than in tropical monsoon forest.

1. The tropical rainforest is a kingdom of trees, and it is extremely rich in species.

2. Perennial high temperature and rain, the average temperature of each month is between 25-28, and the precipitation can reach more than 2000 mm.

3. There are many kinds of animals.

4. The special prosperity of vines and epiphytes is an adaptation mode for special competition for space, which has a great impact on the forest structure.

Tropical rainforest: Tropical rainforest is a forest ecosystem on Earth that is commonly found in tropical areas near the equator, mainly in Southeast Asia, northern Australia, the Amazon basin in South America, the Congo River basin in Africa, Central America, and many Pacific islands. Tropical rainforests are undoubtedly one of the most precious resources that the Earth has given to all living things on Earth. Since more than 25% of modern medicines are now extracted from tropical rainforest plants, tropical rainforests are known as the "world's largest pharmacy".

At the same time, because the photosynthesis of many rainforest plants has a particularly strong ability to purify the earth's air, among which the Amazon rainforest alone produces 1 3 of the world's total oxygen, so it has the reputation of "the lungs of the earth".

Rainforest trees, a lot, have very large leaves. There are also many dangerous animals or plants.

Geography trivia: distribution of tropical rainforests.

Put Kowloon. I didn't see Grandma Jing disturbing.

The characteristics of tropical rainforest climate: high temperature and rain throughout the year, no obvious seasonal difference, the average annual temperature is 25-30, the average temperature of the coldest month is above 18, the extreme maximum temperature is mostly below 36, and the annual precipitation is more than 2000mm.

Tropical rainforests are mainly distributed in tropical climate areas within 5-10 degrees north and south latitudes of the equator, and the most significant characteristics are high temperature, rainfall, and small temperature difference throughout the year.

The seasons are also evenly distributed, with no dry periods, and this type of climate is mainly found in the Amazon plain of South America, the Congo Basin in Africa and the coast of the Gulf of Guinea.

The diurnal variation of temperature is also relatively large, the diurnal range can reach 10-15, and the humidity throughout the year is relatively high, the lower reaches of the Amazon River, the relative humidity can reach more than 90%, so the precipitation is also relatively abundant, often accompanied by thunderstorms.

The cause of tropical rainforest is mainly because it is located near the equator and is controlled by the equatorial low pressure zone throughout the year, and the precipitation type of tropical rainforest climate belongs to multiconvective rain.
