根据湖北省秭归县退耕还林工程状况,建立了秭归县退耕还林工程经济影响评价指标体系,并用层次分析法,计算出各指标权重;用线性加权和函数法,通过影响指数计算模型,计算出秭归县退耕还林工程经济影响指数;调查整理秭归县退耕还林工程实施10年来的数据,运用前后对比法、过程监测法,结合影响指数,从退耕还林工程对地方经济发展、对居民收入、土地生产3个方面的影响对秭归县退耕还林工程经济影响进行了定性与定量评价分析。通过分析,说明了退耕还林工程在保证了秭归县总体经济稳步增长的情况下,合理调整产业结构,不断挖掘自身潜力,在短期内已经开始发挥出巨大的经济效益影响,且其影响正随着工程的稳步推进愈来愈大。
According to the status of the project of returning farmland to forestry in Zigui County, Hubei Province, the index system of economic impact evaluation of returning farmland to afforestation project in Zigui was set up, and the weight of each index was calculated by analytic hierarchy process. By using the method of linear weighted sum function, Out of Zigui County, returning farmland to forest project economic impact index; survey and arrange the return of farmland to forest project in Zigui County 10 years of data, the use of before and after the contrast method, process monitoring method, combined with the impact index, from the conversion of farmland to forestry project on local economic development, Income and land production in three aspects of Zigui County, the economic impact of returning farmland to forest qualitative and quantitative evaluation analysis. Through the analysis, it is demonstrated that the project of returning farmland to forestland, under the condition of guaranteeing the steady growth of Zigui County’s overall economy, reasonably adjusting the industrial structure and continuously taping its own potential, has begun to exert enormous economic benefits in the short term, The steady progress of the project is getting bigger and bigger.
