商洛市退耕还林综合效益评价和生态补偿策略研究

在调研的基础上,对商洛市退耕还林综合效益进行了评估,对后续生态补偿策略进行了探讨。结果表明:商洛退耕还林的生态效益显著,控制了水土流失,涵养了水源,增加了碳固定量和氧释放量,按目前退耕面积计算,生态总值达22.36×108元/年。退耕还林改善了商洛农业产业结构,加快了农村剩余劳动力转移,促进了农民增收,但退耕还林后续产业发展缓慢,应适当提高退耕补助标准,构建流域生态补偿机制,多渠道筹集资金,加大扶持后续替代产业力度。

Research on Comprehensive Benefit of Converting Arable Land into Forest Land and Eco-compensation Strategy in Shangluo City

On the basis of investigation,the overall benefit of returning farmland to forest land and subsequent ecological compensation strategy in Shangluo city were analyzed.The results showed that its ecological benefit was very significant.It controlled the soil erosion,conserved water,and increased the amount of carbon fixation and oxygen release.In terms of the current farmland area,the ecological value reached 22.36×108 yuan per year.It promoted regional agricultural structure,sped up the transfer of rural surplus labor force,and increased farmers' income.However,the follow-up industry of returning farmland developed slowly.So,the compensation should be increased appropriately,the basin ecological compensation mechanism should be built,the funds should be raised through various channels,and the follow-up efforts to substitute industries should be strengthened.
