With the rapid growth of population and the rapid development of economic in China, urbanization has become an inevitable trend in the development of human society. Inevitably, the rapid urbanization has caused the loss of ecological land, the decline of ecosystem services and the risks of environmental health, thereout, all the facts has been influencing the eco-security of the urban. Although the concept of ecological security has been widely accepted by the society, people still lack of unified understanding of the connotation of ecological security and how to build an ecological security pattern. In this paper, combining the characteristics of urban ecosystem, the objectives, basic principles and framework for the construction of urban ecological security pattern are put forward based on analyzing the connotation of ecological security, distinguishing the concept of ecological security and building the basic principles and objectives of the urban eco-security pattern. The construction of urban ecological security pattern is a multi-scale regional comprehensive problem. In addition to following the basic principle of the construction of the eco-security pattern, the following four aspects should be considered: the people-oriented principle, the watershed adaptation principle, the regional coordination principle and the limited goal principle. At the same time, it is necessary to pay close attention to the coordination between the macro and micro scales, the coordination between the urban areas and the nonmetropolitan areas, the trade-off between the ideal and the realistic goal, and the trade-off between the needs of human existence and the needs of ecological services. The following goals must be achieved by the construction of urban eco-security pattern: a) Solving the problems in the process of urbanization. b) Maintaining the normal material circulation and metabolism in urban areas. c) Maintaining the healthy operation and sustainable development of urban ecosystems. d) Ensuring the urban residential environment health and normal life of residents. e) Meeting the ecological service needs of the urban residents in the foreseeable period. At last, we analyzed the entities, problems and goals in the construction of urban security pattern from the three spatial scales of landscape, city and region.
