北宋时期，江淮地区经济地位重要，但水患频发。其中，地方势力在水利建设中的作用尤为复杂:一方面，田户豪民集团具有双重性，其既与部分基层胥吏勾结侵占水利田、阻止水利设施建设，损害公共利益，又作为民间势力而成为水利工程的重要经费来源;另一方面，地方主政官僚和技术官僚受政绩考核和社会责任感激励而推动治水，发挥了积极作用。同时，中央与地方在治水与漕运上的矛盾、党争等因素也对水环境的治理产生了重要影响。

During the Northern Song dynasty,the Jianghuai region held significant economic importance but was also plagued by frequent floods. Local forces played a complex role in water conservancy construction: on the one hand,the wealthy landowners exhibited dual characteristics-while colluding with some grassroots officials to encroach on irrigation lands and obstruct water conservancy construction,thereby harming public interests,they also served as an important source of funding for water projects as a non-governmental force; on the other hand,local administrative and technical officials,motivated by performance evaluations and a sense of social responsibility,actively promoted water control and played a positive role. Meanwhile,contradictions between the central and local governments over flood control and canal transportation,as well as factional strife,also significantly influenced the governance of the water environment.
