- Abstract:
- In view of the fact that the research on water and soil conservation technology was lagging behind, in order to provide reference for the selection of soil and water conservation technology in the watershed in the future, the current water and soil conservation technology in the Xiannangou watershed of Ansai County was evaluated by using the analytical hierarchy process model and Logistic regression model on the basis of the water and soil conservation technology assessment system established by us. The results showed that the suitability of soil and water conservation technology in the Xiannangou watershed was 4.1,(the measured results under the first, second and third level indexes were 4.167 1, 4.105 7 and 4.094 7, respectively), and had entered the highest level of the suitability state, in which the technical suitability was the highest, indicating that the currently applied soil and water conservation technology can meet the requirements of the water and soil erosion control; in the technical suitability, the site suitability was higher, which was consistent with the expert judgment; conversely, in the selection of soil and water conservation technology, the suitability of technology should be met first, and technology suitability could be considered as a veto indicator; at present, the suitability of the soil and water conservation technology system in the Xiannangou watershed has entered the highest level with the value of 4.1, there was still room for the further improvement. In the future development process, it is necessary to develop new soil and water conservation technologies and further optimize the soil and water conservation technology system, according to the new demands in the new era. The calculated results were consistent with the actual survey data, which verifies the rationality of the evaluation system established by the Project(2016YFC0503702), and revealed the essence of the selection and application of soil and water conservation technology.
