Ecological technology evaluation model and its application based on Logistic Regression

•Three-stage evaluation method was established based on Logistic Regression Model.•The weight of the model avoids the subjective factor of human being.•Modularly assesses the various elements of ecotechnology.•The evaluation process is dynamic because of the weight updating.•The model provides reference for the design of ecological engineering construction scheme. In order to cope with degradation and unsustainability of ecosystems, many countries had developed a large number of ecotechnologies. Before learning ecotechnology from other regions, we should evaluate the technology to judge whether it is suitable for our own situation. Based on the lack of scientific and reasonable index system as well as evaluation model in ecotechnology evaluation, we constructed a comprehensive evaluation index system consist of the eco-technology attributes, the implementation conditions, the implementation effects and the popularization potential; and established three-stage evaluation method with Logistic Regression Model according to the analysis of advantages and disadvantages of commonly used assessment models. According to our understanding degree of ecotechnology, the model could not only realize the comprehensive evaluation of ecotechnology as a whole, but also modularly assess the various elements of technology, and the evaluation process is dynamic and objective. We realized the evaluation model of ecotechnology based on the investigation on soil and water conservation technology in the Loess Plateau, and verified its effectiveness using the data of Nangou Village. The results show that the three-stage evaluation method based on Logistic Regression Model is suitable for ecotechnology assessment. The model can not only provide scientific and effective support for the introduction and popularization of ecotechnology, but also provide reference for the design of ecological engineering construction scheme.
