By means of literature review, field investigation, discussion and communication, we made a review on the eco-environment status and management situation of Taihu Lake Basin and summarized the experiences and deficiencies in the joint management and protection of the Taihu Lake Basin. On this basis, we put forward some policy measures to strengthen the joint management and protection in the following aspects: promoting the legislation of basin management, issuing guidance on joint management and protection, unifying plans and standards, strengthening cooperative work, adapting to the carrying capacity of water resources, green development, etc. We hope it will be helpful to improve the integrated management of boundary-sharing basin and the implementation of river and lake chief system for Taihu Lake Basin.
