the impact of deforestation
.The quantity of forest decline. Would cause the changing the physical and biological factors affecting the soil, water, air, wildlife and environment.The ecological balance, causing natural Deforestation is affected in the following aspects:
.1. Soil resources
1.1 soil erosion, normal flora in the tree, shrub, weed, every part of the tree as the role. To help prevent from rain to the ground directly. Resistance to flow of water. Reduce the speed of water to sediment, soil., but if the empty space rate. Soil erosion is severe. Soil loss will increase
.1.2 lack of fertile soil. The ground weed or forest cover. To blow the soil by rain or wind will happen much, especially at the soil surface
2. Water resources
2.1 floods in the rainy season. Any action to disturb the soil, such as deforestation, forest fire, wood, induction drag surface tightly. The pore size decreased. Infiltration through the soil decreased. Cause runoff facial skin soil increased until the drainage time.2.2 drought in dry season. To destroy forest reclaim the wide area that forest area no two consecutive big piece is going to cause evaporation of water from the soil surface is high. But the infiltration through the soil is low. Soil adsorption and collect water in the soil.Feed stream is minimal or stream are knitted dry. Drought and water shortage appeared in late 2534-2536 and early 2535-2537 and years 2536 has การรณรงค์เกี่ยวกับ acute water shortages extensively. By requestTo reduce the loss of water use and consumer
.2.3 water quality deteriorated water quality and physical, chemical, and biological properties are impaired. If there is a change or destroy the forest area. Contamination of sediments that carried by runoff through the surface of the soil or in the form of other also.In the guidelines for the passage of water. Causing contamination and make dirty water, more or less, and likely more passive. A double, which is different from the upstream area of forest cover is of good quality water flow.The sediment in the water or down to Lu sea to make water in opaque thick. The light from the sun, which is very important in photosynthesis cannot shine. Hinder movement of photosynthetic plants.3. Economic and social 3
.1 wood is expensive. Survey the use of wood in the country were high and not sufficient to meet demand. Those who want to use it to smuggle cutting wood in the forest. When the demand is more and more. Prices are usually expensive, so cause career.The illegal cutting trees for sale!3.2 migration, due to forest destruction. Lack of fertile ground, or from the heavy rain with the occurrence of soil erosion, down from the area of forest is destroyed. Blow houses things and destruction of human life.Immigration to new territory, it happens. Because the old place unsafe existence as occurred in the south, the area.The tune, a. phipun T. Kiri Wong, lansaka, Nakhon Si Thammarat. The drought that immigrants have come to work in local politics 4 4 other
.1 to wild policy is one that the government has done to prevent destruction of the forest area. The understanding between the members of the house of Representatives by saying The forest cover will be intercepted wood cutting more
4.2 campaign with the degraded forest area the people do eat. The forest was destroyed and conditions worsen. Advertising of the candidates to the election as a member of the house of Representatives. Have to promise people thatEat when elected is lobbying for the people authority according to self, promised a political problem nationally important
.4.3 to buy wood from abroad. Although the forest area as ever use rich has been destroyed. The tree to use out. But demand for wood to other activities.The one that did was to buy wood from abroad, make money out of the country each year, very
.5. Urban environment / world
5.1 air pollution due to respiration of all living things will release carbon dioxide. If there is a lot of trees or forests enough. These trees to absorb carbon dioxide in the daytime to.Or gas caused by incomplete combustion, such as carbon monoxide is absorbed by พืชชั world-advanced these. Polluted air will not happen!5.2 wastewater that is less in the dry season of all brook, stream and river, causing water conditions is broken or near broken distribution. Because the concentration of contaminants in high waterThe problems of wastewater especially Creek, streams, the water flows slowly in the plain. Neap tides and extinct creatures in the water, the lack of water, lack of water, and lack of fresh water irrigation made fire water, etc.!5.3 global warming greenhouse effect (or Greenhouse Effect) regular various gas that accumulates in the atmosphere over the earth's surface to 25 kilometers. Gathered into a shield surface is fitted with our warmth.A mirror in the greenhouse or "greenhouse" created to keep the temperature inside greenhouse tree alive. Because these gases allow heat from the sun through down fails.
