Abstract: Under the background of regional integration,the evaluation of the land resources to be reserved is beneficial to the intensive and efficient land utilization,maximizing the land economical value,and relieving the financial pressure caused by river basin regulation. In this paper,the potential land available for development in Shima River Basin of Dongguan is investigated and evaluated. Firstly,the screening index system of land is established,and the potential plot for reservation is identified. Then,the planning conditions,reserve potential and economic benefits of the intentional land are evaluated. Finally,some proposals for land reserve is proposed. This study explores and establishes a complete land resources evaluation system of "screening-evaluation-reserve planning",which provides references for the integrated development of river basin and the formulation of land reserve plan.

Key words: land resources evaluation, spatial expansion and optimization, basin integrated development, land reservation, Dongguan
