跨域水治理中的尺度重构：以东江为例

水治理往往呈现地理空间上的跨区域性、组织制度上的多层级性以及管理单位上的跨部门性等多尺度特征。本文以珠江水系干流之一——东江的水资源跨域分配、开发与保护等治理过程为例，采用“物质-组织-表达”的尺度框架，分析了在不同的历史时期，东江水资源相关政策从出台到执行过程中所经历的多次尺度重构。主要结论如下：（1）总体上，国家在东江水供港和流域生态补偿政策等跨域水治理政策出台和执行过程的各个阶段都掌握着主导权，同时各级政府、民众和相关团体组织等也开展针对东江用水的尺度争夺。（2）物质空间上，随着时间的推移和社会政治背景的变迁，东江水治理在政治尺度和生态尺度之间切换并存。（3）组织空间上，横向和纵向的尺度重构在东江水跨域开发和治理的过程中同时发生。（4）话语表达空间上，国家和地方的众多行为体都在尝试塑造针对东江水治理的话语，这些话语将不同的主体纳入到东江水开发与治理的框架之内或将其排除在外，实现尺度的重组。

Rescaling of inter-jurisdictional water governance: A case study of the Dongjiang River

Taking the inter-jurisdictional water governance of the Dongjiang River basin as an example, this paper explores scalar reconstructions in the material space, organizational space and discursive space over the course of policy formulation and implementation. Major findings are as follows: 1) Overall, the central government dominates formulation and implementation of water governance policies in the Dongjiang River basin. Meanwhile, sub-national governments, public groups and other relevant organizations are also engaged in the competition of scalar construction. 2) In material space, the focal scale of water governance in the Dongjiang River has shifted and co-existed between the political and ecological scales.3) In organizational space, the horizontal and vertical scalar reconstruction of the Dongjiang River water governance policies occurred simultaneously in the process of policy formulation and implementation.4) In discursive space, various actors at national and local scales are trying to shape their own discourses on the Dongjiang River water governance. These discourses include and exclude certain subjects into and from the framework of policy implementation, by which scalar reorganization is achieved.
