The idea and principle of ecological civilization must be insisted during urbanization process. The central government has demanded to strengthen the system building for ecological civilization, and protect ecological environment relying on a complete legal system. Rapid process of urbanization and social development urgently requires legislation in urban soil and water conservation. The government should focus on the implementation of goals and responsibilities formulated in soil and water conservation laws in each functional urban area, and establish coordination mechanisms for soil and water conservation in relevant plans. The government should determine the key prevention and control areas based on the characteristics of cities, and implement the strictest soil and water conservation management process in all construction projects. Controlling urban rain flood and earthwork construction should be reinforced, in order to speed up the governance and ecological restoration of soil and water loss. Besides, a monitoring, announcing, reporting, and public supervising system should be established with clear legal responsibilities and precise penalty clauses.
