The Method and Model of Ecological Technology Evaluation

Abstract

In order to evaluate ecological technology scientifically, we constructed a modular “three-stage evaluation method” based on qualitative evaluation, semiquantitative evaluation and quantitative evaluation, and established the theoretical models of the four kinds of ecotechnology, such as soil and water conservation technology, desertification governance technology, rocky desertification governance technology and ecological restoration technology. We gave the quantification criteria of the first-level and second-level index commonly shared by four kinds of ecotechnology and defined the quantification criteria of the third-level index of reflecting the heterogeneity of soil and water conservation technology. An ecotechnology evaluation model combining Analytic Hierarchy Process and Logistic regression was established based on soil and water conservation technology. The rationality of the evaluation method and model were verified by field investigation data of soil and water conservation technology in Gaoxigou. The evaluation method and model could provide scientific basis for the effective introduction and popularization of ecotechnology.

How does the Traditional Heavy Industry Use Ecotechnology to Achieve the Ecological Innovation Goal? Analysis Based on Expert Survey in China’s Shipbuilding Industry

“…This study assumes that major types of ecotechnology considerably affect the ecological innovation goals and that the mutual influence and interaction of two technologies is the key to solving the ecological innovation problems associated with the traditional heavy industry. Related industries have used similar ideas for the research and promotion of ecotechnology [12]. Based on the expert opinion of China's shipbuilding heavy industry and empirical analysis, we identified the elements of two variables (i.e., ecotechnology and target), the internal relation between single variables, and the relation between the two variables; furthermore, we defined the internal influence law of the two variables and externalized them and verified the hypothesis of this study.…”

Benefit Evaluation of Water and Soil Conservation Measures in Shendong Based on Particle Swarm Optimization and the Analytic Hierarchy Process

“…Each level, according to the expert opinion, gives the evaluative weight and score of each index. Then, through a structural quantitative model and evaluation of the impact factors of the decision-making problems, the qualitative problems are quantified, and the real problems are in decision-making [60]. However, there are often subjective abilities and other aspects of the impact in the process of practical application.…”

“…With the help of computer language, it may solve the repeated detection and correction process. By applying the analytic hierarchy process, the authors could made the evaluation conclusion more objective [60].…”

Comprehensive Assessment of Soil Conservation Measures by Rough Set Theory: A Case Study in the Yanhe River Basin of the Loess Plateau

“…Due to the drawbacks of traditional evaluation methods, the qualitative evaluation method represented by the item-by-item evaluation method, weighted evaluation method, and expert scoring method, often are used in assessment research [24][25][26]. Experts will use their own experience to select indicators and determine the index weight, which although simple and easy to use, results in greater subjectivity [27]. Rough set theory is a data analysis tool that does not need to provide any prior information beyond the set of problems being studied, which composes a multi-index comprehensive evaluation method that is data-driven [28].…”
