【摘要】 黄土高原自然条件特殊,耕作农业以引水灌溉为主。长时期的引水灌溉使土壤理化性质发生改变,并由此引发了地裂缝、滑坡等地质灾害,同时地下水水位的上升,使地表土壤盐渍严重。以民和地区,尤其是区内生态地质问题严重的黑方台为例,论述了黄土高原农业灌溉对生态地质环境的影响,提出从治水入手,改进灌溉方式,优化产业结构,并配合工程措施、生物措施以改善农业地质环境,促进黄土高原农业可持续发展。更多还原

【Abstract】 Irrigated farming is the primary kind of agricultures in loess plateau.But as the special geological condition,irrigation causes a series of problems of agroecological geology,such as landslide,salination and so on.Taking Minhe area,especially the Heifang platform for example,the effect causes by irrigation in are analyzed.And for the sustainable development of agriculture in loess plateau,some agricultural measurers are put forward,such as advanced water saving irrigation techniques,optimizing the agricultural configuration,combining with project to improve the geological environment.更多还原
