- 摘要:
- 为识别影响水土流失综合治理适宜模式关键因素和分区针对性地开展水土流失治理,综合考虑自然环境和社会经济条件,应用专家打分、层次分析、模糊数学、空间分析等方法,开展了基于生态与生产功能权衡的赣南水土流失综合治理模式适宜性评价研究。结果表明:通过构建22项评价指标组成的区域水土流失综合治理模式评价指标体系,成功将赣南18县(市、区)划分为偏生态防护型、偏高效开发型和生态防护型与高效开发型皆可3类水土流失综合治理模式适宜区,并针对性地提出了分区综合治理对策建议; 土壤侵蚀现状、主体功能定位、地方水土流失治理能力、地形、农业人口是生态防护型水土流失综合治理模式适宜性的关键影响因素; 区域开发利用现状、土壤肥力状况、区域便捷程度、地形、农业人口与农业发展状况是高效开发型水土流失治理模式适宜性的关键影响因素。权衡生态与生产功能可遴选水土流失综合治理模式关键影响因素,识别各行政区适宜治理模式,为针对性治理提供依据。
- Abstract:
- To identify the key factors influencing the suitable model of comprehensive soil erosion control and to carry out targeted comprehensive control of water and soil loss in different regions, the natural environment and socio-economic conditions affecting the selection of soil and water loss control model were simultaneously considered, and the study on the suitability evaluation of the comprehensive management model of soil and water loss in southern Jiangxi based on the balance between ecological and production functions was carried out by using the methods of expert scoring, analytic hierarchy process, fuzzy mathematics and spatial analysis. The results were as follows. The evaluation index system of regional comprehensive control mode of soil and water loss composed of 22 evaluation indexes was constructed. 18 counties(cities and districts)in southern Jiangxi were successfully divided into three types of suitable areas for comprehensive control mode of soil and water loss: tending to ecological protection type, tending to efficiency development type, and type with ecological protection and high-efficiency development both suitable, and targeted countermeasures and suggestions for regional comprehensive control were finally put forward. The current situation of soil erosion, main functional area orientation, ability of local soil and water loss control, topography and agricultural population were the key factors affecting the suitability of the comprehensive control model of ecological protection soil and water loss. The current situation of regional development and utilization, soil fertility, regional convenience, terrain, agricultural population and agricultural development were the key factors affecting the suitability of efficient soil and water loss control model. By weighing the ecological and production functions, the key influencing factors of the comprehensive control model of soil and water loss can be selected, and the suitable control model in each administrative region can be identified, which can provide scientific basis for targeted soil and water loss.
