Study On The Ecological Service Function Of Main Artificial Forest In Changtu County Of Liaoning Province

Forest service function and resource assessment is necessary demand of ecological civilization construction and the development of the green economy. In this paper, according to the positioning of continuous observation data and the Liaoning provincial forest inventory data, the farm of Mongolian Scotch pine and poplar plantation main ecological service functions of the Liaoning Province Changtu County to pay for comparative analysis and evaluation of economic value. The main conclusions are as follows:1. Comparison of the annual climate, forest temperature higher than forest outside 0.9 degree Celsius, the underground temperature inside of the forest is higher than that outside the forest 2.3 DEG C, underground air humidity higher than 8.0% of the forest, the wind speed Lynne Billing drop to 30%.2. Organic matter, total nitrogen, available nitrogen, total phosphorus, available phosphorus content, and C/N of poplar were 1.12%,0.11%,48.7mg/kg,0.00125%, and 0.525mg/kg 10.57 and Pinus sylvestris forest respectively to 1.09%,0.11%, 43.9mg/kg,0.00125%,0.403mg/kg and 10.83. Chemical indicators in poplar forest were higher than Pinus sylvestris var.mongolica.3. In the purifying atmosphere of Poplar Plantation in one year can absorb sulfur dioxide 7287430.92kg, fluoride 16900.35kg, nitrogen oxides 202804.2kg, dust removal 1122183kg; and Pinus sylvestris var. mongolica plantation year can absorb sulfur dioxide 717861.105kg, fluoride 37654.31kg, nitrogen oxides 48586.2kg, sluggish dust 81867.75kg.Nutrient cycling of Poplar Plantation for 141962.94kg, Pinus sylvestris var. mongolica plantation year net retention of nutrients for 413063.677kg; in fixing carbon and releasing oxygen function aspects poplar in solid carbon content for 21.33 million tons, in release oxygen for 5.709 million T, Pinus sylvestris var.mongolica is 3.42 million tons and 9.16 million tons of poplar and Scotch Pine in the ability of water conservation were 6033.43 m3 and 1445.44 million m3.4. Air purification, nutrient cycling, fixing carbon and releasing oxygen and water conservation of the four ecological function value of Poplar Plantation for 127833.51 million yuan per year., Pinus sylvestris varf rnongolica plantations for 24492.56 million yuan per year. Two kinds of artificial forest ecological function value for 152326.07 million yuan per year. The fixing carbon and releasing oxygen and water conservation function of the two value accounted for 98% of the total value.
