Abstract: Ecosystem degradation has been a major global environmental problem. Ecological control technologies aimed at restoring and rebuilding ecosystems have received considerable attention. Among many direct and indirect technologies, there is still a lack of systematic, scientific and perfect evaluation methods on how to select the most appropriate technology. Based on the review of the theories, methods and elements of technology evaluation in other fields, and taking several factors involved in desertification control technology as an example, a general concept model of “12-dimensional double-circle” ecological control technology suitability evaluation is proposed for the first time, which includes twelve dimensions in two categories: (1) endogenous factors (internal circle): restrictive, independent, economic and operational ones; (2) external factors (outer circle): objectives, regions, timeliness, political system, ideology and attitude, social economy, degradation and opportunity cost. It is also pointed out that when the conceptual model is applied to the suitability evaluation of a specific ecological control technology, the number of influencing factors can be reduced according to the need, and the influencing factors need to be concretely translated into operable indicators. In addition, the suitability of technology has spatial-temporal heterogeneity.

Key words: ecological control technology, suitability evaluation, influencing factors, “12-dimensional double-circle” conceptual model
