【摘要】 本文选取全国退耕还林工程典型地区陕西省吴起县为研究区,采用替代价格法、影子工程法、直接市场法,并引入市场逼近系数和支付意愿系数,对该县退耕还林工程的生态价值进行了评估。结果表明,吴起县退耕还林工程的生态价值为11528.57万元/年。其中,涵养水源价值1151.69万元/年、保育土壤价值8207.90万元/年、净化环境价值8.97万元/年、固碳制氧价值2114.49万元/年、改善小气候价值45.52万元/年。通过对退耕还林工程生态价值的合理评估为建立退耕还林生态补偿机制提供了有益参考。更多还原

【Abstract】 Wuqi County,Shanxi Province,a demonstration area of the conversion of cropland to forestland in China,was chosen as a study case to evaluate the forest ecological value of the conversion of cropland to forestland project by using method of replacement price,shadow engineer market price and adjusting with approaching market coefficient and coefficient of willingness to pay.Results showed that the total actual ecological compensation value was up to 115.29 million Yuan,which 11.52 million Yuan for water conservation,82.08 million Yuan for soil conservation,0.09 million Yuan for environment purification,21.14 million Yuan for carbon dioxide fixation and oxygen release and 0.46 million Yuan for improving microclimate.The evaluation of ecological value of the land conversion project can be as references for proposing regulations for ecological compensation.更多还原
