This article analyzed the abandoned quarrys negative impact on urban landscape and the development of the abandoned quarrys landscape transformation in Western countries and China. Then it constructs the theory, which combine the ecology domain and cultural landscape domain, to work with the damaged ecosystem and to satisfy the new functional requirement of abandoned quarry. This article would take Dakengding, one of abandoned quarries located in Zhongshan city, China, as an example and create quarry landscape regeneration strategy, which involves quarry ecological restoration and human landscape construction. Fund guarantee method for Abandoned quarries landscape transformation in urban area and post-custody are also discussed in this paper.

Candle Lake wetland at Qingxiu Mountain scenic spot is one of the most important parts of the 'China Water Town' program in Nanning city. In order to figure out the scientific rationality of the situation and design of wetland system, five pilot programs are set up based on flow velocity of three inlets, quantity and position of five outlets and the shape of center island to simulate the flow field and velocity of Candle Lake wetland by using two-dimensional numeral simulation. The results indicated that as follows: 1. The flow field and velocity of Candle Lake wetland can't be improved by increasing the velocity of inlets in the wetland system, so that the problem of large standing water can’t be solved. 2. The flow field and velocity of Candle Lake wetland are influenced by the position and quantity of outlets, especially the outlet 2, outlet 4 and outlet 5, which can improve the flow field and velocity effectively. 3. The flow field and velocity of Candle Lake wetland are also influenced by the shape of shoreline. Optimizing shoreline of Chengxiang Island can improve the flow field and velocity of Candle Lake wetland near the island very well. The flow field and slow velocity of Candle Lake wetland can be improved effectively by the optimizing shape of the Chengxiang Island and the position of outlet 4 and outlet 5, and the problems of large standing water and circulation can be solved very well.
