[Abstract] With the continuous progress of China's economic concept and economic development, people have higher and higher awareness of environmental protection and safety in agricultural production, which puts forward higher requirements for the economic model of agricultural production. At the same time, people 's demand for natural agricultural products is also increasing year by year. Take the innovation of rice crab ecological co culture technology as an example to better realize the innovation development and healthy sustainable development strategy of agricultural industry.

河蟹,也叫“螃蟹”或“毛蟹”,学名叫中华绒螯蟹,属于节肢动物门甲壳纲动物。河蟹常穴居于河、江、湖沼的泥中,以水中的鱼虾等浮游生物为食。河蟹是我国经济价值较高的水产品,河蟹的肉质鲜嫩,是深受人们喜爱的一味食品。稻田中养殖河蟹能够有效的提高稻田的利用率,河蟹的生长为稻田除草、除虫、松土,河蟹的粪便为稻田提供肥料;稻田为河蟹提供含氧量高、营养丰富、阴凉避暑的良好生长环境,通过这种种养结合的高效生产方式,实现稻蟹双收、渔农双赢。
1 榆林横山无定河流域对稻蟹共养的环境影响
无定河地处黄河流域黄土高原北部,半干旱大陆季风性气候,其流域大多位于内陆地区,每年降雨相对集中在汛期,且大多为暴雨,所降水较难利用。无定河流域也是黄河中游含沙量最大的支流,水土流失情况需要提起高度重视,水污染情况严重,同时对于该地区水资源监管治理情况比较孱弱,导致水资源的供需矛盾尖锐,经常出现水事纠纷。……
