The Ecological Landscape Planning Of Urban Green Space System

City, as a special geographical landscape, is an ecological system mainly composed of human beings, and is embodied by populated citizens. With the increasingly rapid speed of urbanization, the urban and its surrounding environment are worsening. Most environmental problems are connected with industrialization, urbanization and modernization, and the sustainable development has challenged ecology. One of the best ways of solving the problem is to improve urban environment to make it develop healthily and sustainably.For a long period, the segment of urban green space system planning in our country is frail, people from leader, planners to citizens know little about green space system, and do not consider the problem systematically. The index system of greening is still not satisfactory, which often only include rate of Greenland, rate of green coverage, and public Greenland owned by per person, while these indexes can not reflect the relationship between the distribution and structure of the whole urban green space system and its function. Theoretically, our country has adopted the mode of recreational theory of the Soviet Union, which has enhanced the greening of our country to some degree, but could not reflect the ecological effects and economical effects.The planning concept of urban green space system has changed greatly since 1990's. The emergence of 'ecological landscape' make people be more aware of the function and effects of landscape architecture, that is to say, improving urban environment, and maintaining urban ecological balance now become one of the important function of urban Greenland. New epoch calls for new theory. The ecological landscape planning of urban green space system combined the theory and method of landscape ecology with urban green space system planning has opened a new way of rational distribution of urban Greenland, the better performance of the ecological function of Greenland, and the achievement of comprehensive function of recreation, ecology, environmental protection, culture, and education.Pointed at the defects of current urban green space system and the specific condition of Ba'nan central district Greenland, and combined the theory and method of landscape ecology with the...
