基于密切值法的林农复合经营模式的综合评价研究——以江苏省泗阳县为例

针对林农复合经营系统的多功能性,从生态功能、经济功能、社会功能3个方面构建了林农复合经营的综合评价指标体系,并且运用密切值法对不同复合模式进行评价。最后,对江苏省泗阳县的林农复合经营的综合效益进行实证研究,运用建立的评价指标体系和密切值法选出较优模式,以期为当地发展林农复合经营提供理论依据和方向指导。结果表明：无论从生态功能、经济功能、社会功能来看还是从综合效益来看,泗阳县的杨农复合经营模式都优于纯杨树的种植模式。其中,杨树-蒲公英复合经营模式和杨树-蘑菇复合经营模式在各个功能方面较优于其他模式,当地农民可以根据实际需要进行选择,以充分利用林地资源,增加经济收入。

Research on Comprehensive Evaluation of Agroforestry Models Based on the Osculation Value Method

Considering its multifunctional, this paper established the comprehensive evaluation index system of agroforestry from three aspects, including ecological function, economic function and social function,and used the osculation value method to evaluate the value of different composite models. Finally, this paper make an empirical study on the comprehensive benefits of agroforestry of Siyang County in Jiangsu Province, using the established evaluation index system and osculating value method to select the superior model, in order to provide theoretical basis and guidance for the development direction of local agroforestry. The results show that： agroforestry models in Siyang County are better than the pure poplar planting model, in terms of ecologicalfunction, economic function, social function and comprehensive benefits. Among them, the poplar-dandelion multiple operation model and poplar-mushroom multiple operation model are better than other models in each function. Local farmers can make their own choice according to the actual needs to make full use of forest resources and increase the economic income.
