| Abstract: |
| 【Objective】Comprehensive and systematic evaluation of the ecological health status of large irrigation areas provides an important guarantee for food security and agricultural modernization in China. 【Method】The comprehensive evaluation index system of water-saving ecological irrigation area was preliminarily constructed from six aspects of irrigation water-saving system, environmental quality of irrigation area, ecological resources of irrigation area, socio-economic effects, service management system and humanistic ecological environment. 19 evaluation indexes were selected from 36 indexes by using the screening model, and 85.57 % of the information was expressed. Based on analytic hierarchy process and fuzzy comprehensive evaluation method, the comprehensive evaluation model of water-saving ecological irrigation area was proposed, and the comprehensive evaluation empirical study was carried out on Jiaokou Irrigation District in Shaanxi Province. 【Result】The Jiaokou Irrigation District was at a medium healthiness level, and the comprehensive evaluation levels of excellent, good, medium, fair and failing levels had an affiliation degree composite score of 0.224, 0.169, 0.409, 0.159 and 0.039 respectively; in the evaluation of the criterion layer, the irrigation water-saving system, the environmental quality of the irrigation area, the ecological resources and the social and economic effects of the irrigation area were at the medium level, the service management system and the humanistic ecological environment were at the excellent level The reasons for the destruction of the healthiness of the water-saving ecological irrigation district of Jiaokou Irrigation District were analyzed. 【Conclusion】The service management of Jiaokou irrigation area is good, but there is still a certain gap between the water-saving projects and the ecological environment of the irrigation area and the modern irrigation area. The research results can provide theoretical basis and technical support for scientific assessment and construction management of water-saving ecological irrigation areas. |
