"Care for vegetation and green the motherland" PPT courseware 4

Vegetation: All plants growing in an area are called the vegetation of this area.

Rainforest

1. Mainly distributed in Yunnan, Taiwan, and Hainan in the south.

2. In areas where tropical rain forests are distributed, the annual rainfall is very high, usually higher than 1800 mm, and in some places it reaches 3500 mm. That’s why it’s called a tropical rain forest.

3. Most of the trees in the rainforest are dicotyledonous plants, with thick leathery leaves and shallow root systems. The roots used for nutrition are usually only a few centimeters deep. This makes the nutrients easily washed away by rain. So this ecosystem is particularly fragile.

evergreen broadleaf forest

The structure of a typical evergreen broad-leaved forest is much simpler than that of a tropical rain forest, with shorter community heights and a neater crown. Trees usually have only two layers, with few interlayer plants such as vines, strangler plants, and epiphytes, and typical tropical rainforest phenomena such as flowers on old stems and plank roots rarely appear.

Although the evergreen broad-leaved forest is also evergreen all year round, it is different from the tropical rain forest. There are certain seasonal changes in the evergreen broad-leaved forest, similar to the summer green broad-leaved forest. The flowering period of evergreen broad-leaved forests is mostly concentrated in late spring and early summer, and the fruits are mostly in autumn. Some animals in evergreen broad-leaved forests hibernate, especially ectotherms such as amphibians and reptiles.

Anti poaching Geam Anti poaching Geam

After 1990, a large number of poachers entered Hoh Xil and illegally hunted wild animals, mainly Tibetan antelopes. Tens of thousands of Tibetan antelopes were shot every year. The anti-poaching armed forces of the local government and civil society fought desperately against the poachers under extremely poorly equipped conditions.

In 1992, Deputy Secretary of the Zhiduo County Party Committee Jesan Sonamdajie formed an anti-poaching team. On January 18, 1994, he was the only one left in a gunfight with 18 poachers at Sun Lake in Hoh Xil, and was eventually shot. Sacrifice, surrounded by more than 1,000 intercepted Tibetan antelope skins.

In 1995, Chika Zhaba Dorje, deputy secretary of the Political and Legal Committee of the Yushu Prefecture People's Congress, reorganized the anti-poaching team and dealt a heavy blow to the poachers. In three years, more than 4,000 Tibetan antelope skins were seized. Zhaba Dorje passed away at home on November 8, 1998.
