宽谷丘陵区是以黄土高原丘陵沟壑区第Ⅴ副区为主体,涉及第Ⅱ、第Ⅲ、第Ⅳ副区的部分区域。该区域沟壑纵横,常年降水稀少,气候干旱,水土流失严重,人民生活水平低。水土流失、干旱、低产、贫困是该区突出的生态、社会和经济问题。选择黄土丘陵沟壑区第Ⅲ副区的中山沟流域东山村作为示范点,在治理水土流失的同时,配套集雨节灌措施,培育和发展葡萄等特色产业,大力推广节水农业,通过减少化肥、农药施用量,以减缓面源污染。并在综合确定监测指标的同时,通过定点监测、调查访问等监测方法,采用层次分析法建立了示范效益监测与评价指标体系,从而科学合理地评价示范效应及生态经济系统。
The hilly area in the hilly area is mainly the Ⅴ sub-district in the hilly and gully region of the Loess Plateau, and covers some areas of sub-districts Ⅱ, Ⅲ and Ⅳ. Longitudinal and ravine ravines in the region, sparsely populated perennial, arid climate, soil erosion is serious, the people’s living standards are low. Soil and water loss, drought, low yield and poverty are the prominent ecological, social and economic problems in this area. Dongshan village of Zhongzhaogou watershed, which is the third sub-district of the loess hilly and gully area, is selected as a demonstration site. In the process of soil and water loss control, rainwater harvesting and water saving measures are also provided to cultivate and develop special industries such as grapes, vigorously promote water-saving agriculture, , Pesticide application rate, to reduce non-point source pollution. At the same time, the monitoring indicators are determined synthetically. At the same time, through the monitoring methods such as spot monitoring and investigation, the analytic hierarchy process (AHP) is used to establish the indicator system of demonstration benefit monitoring and evaluation so as to scientifically and reasonably evaluate the demonstration effect and eco-economic system.
