Land use change is an important driving force factor affecting the river water environment and directly affecting water quality. To analyze the impact of land use change on water quality change, this study first analyzed the land use change index of the study area. Then, the study area was divided into three subzones based on surface runoff. The relationship between the characteristics of land use change and the water quality grade was obtained by grey correlation analysis. The results showed that the land use types changed significantly in the study area since 2000, and water body and forest land were the two land types with the most significant changes. The transfer rate is cultivated field > forest land > construction land > grassland > unused land > water body. The entropy value of land use information is represented as Area I > Area III > Area II. The shift range of gravity center is forest land > grassland > water body > unused land > construction land > cultivated field. There is a strong correlation between land use change index and water quality, which can be improved and managed by changing the land use type. It is necessary to establish ecological protection areas or functional areas in Area I, artificial lawns or plantations shall be built in the river around the water body to intercept pollutants from non-point source pollution in Area II, and scientific and rational farming in the lower reaches of rivers can reduce non-point source pollution caused by farming.

Encountering the articulation of the strongness of local authorities and market forces in China’s development, attention has been paid to the changing central state which recentralised the regulation capability of localities which has more discretional power on resources utilisation, land for example, in the post-reform era. Yet it is still not clear-cut what drives the state rescaling in terms of land governance and by what ways. After dissecting the evolving policies and practices of construction land supply in China with the focus on the roles of state, we draw two main conclusions. First, the policy trajectory of construction land supply entails a complicated reconfiguration of state functions, which is driven by three interwoven relations: land–capital relation, peasant–state relation and rural–urban relation. Second, state rescaling in terms of the governance of construction land provision works via four important approaches: limited decentralism, horizontal integralism, local experimentalism and political mobilisationism. By reviewing the institutional arrangements of construction land provision and the state rescaling process behind them, this article offers a nuanced perspective to the state (re)building that goes beyond the simplified (vertical or horizontal) transition of state functions.
