Ponds is an important ecological sustainable urban development depends on infrastructure, urban residents can be one of the foundations of sustainable access to natural service plays an important role in the city, such as: regulation of the urban river flows, drought prevention anti- floods; supplementary urban groundwater, urban water; adjust the components of urban air, purify the air; purify the sewage of urban rivers; regulating urban micro-climate, maintenance of urban living environment; beautify the urban landscape, tourism resources; educational and scientific value; for urban wildlife habitat. Together as the socio-economic development, human activities and climate change, water environment a greater degree of change, part of the regional pond area significantly reduced or even disappear, it has gradually lost the role. Historical and cultural city, more or less remained the history of the formation of the ponds, some of these ponds are formed naturally, some dug them once in the history of residents in addition to drinking outside production, life important water source, and plays water drainage role is an important part of the pulse of the city water. However, with the development of urban construction and the improvement of the water supply facilities, the historic mission of these ponds have been completed gradually been abandoned been filled, and some houses built on top, and some are gradually silting water drift full of garbage, emitting bursts of odor, became a city sanitation dead. Of course, the of Anyang old town is no exception, and its combined sewer system was formed in the 20 century, 70 years, and now in addition to the minority sections, in most parts of to drainage still Ring River and within the city pond way out, ponds important pollution sources; pollution and fill up in the old town pond phenomenon is very serious, some sections therefore waterlogging, people reacted strongly. Through the analysis carried out on the the ponds status and the meaning of existence, the specific measures proposed transformation of landscape ecology, provide some references in the pond for future conservation practices. Firstly, from the shortcomings of existing ponds as the starting point to analyze the reason and the significance of its environmental, ecological, economic, and other aspects of our ponds are dying. Secondly, through the use of landscape ecology theory for guidance, specific analysis of existing the pond landscape mode and eco mode transformation. Again, start from the basic situation of the Old City by Anyang old city pond, for example, through their history, hydrology, economic and other aspects of the research, analyze the reasons and uses a unique situation in the Old Town, past ponds formed , and is now the pond is the demise of the special reasons, to arrive at the idea of ??the Old City area ponds and moat connected through the stagnant water becomes flowing water, the local conditions of the Old City area ponds divided into two different landscape the landscape ecological transformation mode of delegation discusses in detail the transformation of the old city pond green space for the hydrophilic walkers and street two landscape ecological transformation mode. Finally, specific measures and recommendations for the management of day-to-day maintenance of the pond.
