Assessment of soil and water conservation technology of Zhifanggou watershed based on evaluation indices

Based on ecological technological attributes, application, implementation effects, and the characteristics of their latent variables, an index system in two scenarios was generated with the latent variables as the background, and the index system in two scenarios was verified in the Zhifanggou watershed. The evaluation results in both scenarios are consistent with the actual conditions. The interaction between soil and water conservation technology, their application, and technical systems are directly associated with latent variables. To accurately elucidate the nature of soil and water conservation technology, to clarify the application process of soil and water conservation technology in the Zhifanggou watershed and the technical system of soil and water conservation, based on the data regarding ″Eco-technical evaluation methods, indicators and evaluation model development″ and the survey data of farmers in May 2018, the technology maturity, technical application difficulty, technical suitability, technical benefits, and technology promotion potential were assessed. The soil and water conservation technology evaluation index system includes five first-level indicators and 14 second-level indicators. The indicators are interpreted, and the criteria are judged. The soil and water conservation technology of the Ansai Zhifanggou watershed was evaluated via mutual verification of the first and second indicators. The comprehensive assessment scores of soil and water conservation technology in stages of the Zhifanggou watershed are 0.5399(0.5191),0.6724(0.6628),and 0.7866(0.7748)(the values in parentheses are the secondary indicators). The comprehensive effect of soil and water conservation technology and its application in the basin has continuously improved because the water and soil conservation technology system is continuously optimized, and the coupling degree of soil and water conservation technology selection and application elements is continuously improved.
