Of Forestry and Environmental Economy

Abstract: As the largest terrestrial ecosystem carbon, forests are recognized as the most effective way of biological carbon sequestration, while the carbon absorption is the most economical device.

Compared with industrial emissions, forest carbon sequestration with less investment, the price is low, a large comprehensive benefits, more economically viable and realistic operational.

Keywords:: forestry, environmental protection, economic

Forestry is the essential low carbon economy or the important areas. According to the current stage of China's economic development point of view, the development of low-carbon economy through forestry measures, not only low cost, overall efficiency is good, true absorption and reduction of carbon dioxide, and will not The so-called low-carbon, as some industrial projects, resulting in the production process equipment, a new carbon dioxide emissions.

First, the forest area to reduce the impact on the environment
Deforestation and forest degradation and disasters have led to forest destruction, the stored carbon in forest ecosystem was re-released into the atmosphere. The United Nations <2000 "Global Ecological Outlook>> that the world's forests from the beginning of human civilization, about 76 million hm2 reduced to 3.8 billion hm2, a decrease of 50%, difficult to support the building of human civilization on the global warming had a serious impact. Moreover, the current global trend of deforestation continues. around Copenhagen as well as future international negotiations Many countries and international organizations are actively promoted through the restoration and protection of forest ecosystems to promote the "reduce deforestation and forest degradation caused by carbon emissions (REDD +)" and other policies to control greenhouse gas emissions and slow global warming.

Second, the functions of forests
Carbon sink function of forests. As the largest terrestrial ecosystem carbon, forests are recognized as the most effective way of biological carbon sequestration, while the carbon absorption is the most economical device. As the main terrestrial ecosystems, forests absorb through photosynthesis carbon dioxide and release oxygen and carbon dioxide in the atmosphere fixed in vegetation and soil. Therefore, the biomass of the forest with its huge store significant amounts of carbon. compared with industrial emissions, forest carbon sequestration with less investment, lower costs, integrated effectiveness of large, more realistic operational and economic feasibility. forest carbon sink and many other important ecological functions as the maintenance of global ecological security and climate security has been playing an important leverage.

Third, the impact of forests on climate change
Forests are an important climate change adaptation measures, such as large-scale afforestation and desertification control, with water conservation, water and soil, sand-fixing role; construction of farmland shelterbelts, played to improve agricultural production conditions, enhance the role of food production; construction of coastal shelter, restoration of mangrove ecosystems, and to resist marine disasters, protection of coastal environment of great value. waterlogging and crop varieties with drought, strengthening the coast guard, the reduction of forest fires and pest disasters, such as speed up the breeding of fine varieties of trees to help improve forest itself, the ability to adapt to climate change, forests increased ability to adapt to climate change, in turn, will improve the ability of forests to mitigate climate change.

Fourth, wood forest products processing The role of energy saving
Increased use of wood forest products, improvement of timber utilization, extend the service life of wood and other wood forest products can enhance carbon storage. Chinese Academy of experts to study the draw: with 1m3 of wood substitute the same amount of cement, brick materials, about to 0.8 t of carbon dioxide emissions. This not only save energy and reduce pollution. In addition, the use of shrubs and forest left and planting material generation biodiesel fuel energy forest development, can replace some fossil fuels, both to increase carbon sequestration, and reduce emissions, in order to mitigate climate make a positive contribution to warming.
